AirFanta is a name that I hear more about every day. While it’s a relatively niche company, it’s quickly becoming well-known – at least within the air quality ‘enthusiast’ community – for performant yet affordable air purifiers and air quality monitors. I’ve been using the AirFanta G2 Air Quality Monitor for quite a few months now, but the two products that have always interested me the most are 3Pro and 4Lite air purifiers.

After having the 3Pro set up inside my office for over two weeks now, I am happy to be able to present my full review of the device. For anyone unaware, this purifier is designed to filter a massive amount of air (we will discuss the CADR and more soon!) at a relatively affordable price. It does this by being essentially a pre-assembled CR (Corsi-Rosenthal) Box – a form of air purifier that was itself created due to the need for affordable and effective air purification devices.

While the 3Pro doesn’t embrace the typical DIY aspect of traditional CR Boxes, it has the advantage of having proven performance (no need to worry about whether your DIY box is effective!) and being ready to go out of the box. However, perhaps my favourite aspect of this device over traditional CR Boxes is how easily obtainable it is. While this probably isn’t an issue for anyone in the U.S. or Europe, I find it hard to source good HEPA filters in New Zealand at an affordable price. The 3Pro ensures I don’t run into this issue.

In today’s review of the AirFanta 3Pro, I want to answer a few key questions. Firstly, how does it perform? Secondly, how does it compare to more ‘traditional’ air purifiers? Finally, and most importantly, is the 3Pro worth the markup compared to making your own CR Box at home? By the end of the article, I will share the answers and my opinions regarding each of these questions. Let’s dive in!

The key selling point of the AirFanta 3Pro is its fantastic CADR – especially at this price. For anyone new to air purifiers, CADR stands for clean air delivery rate, which indicates how much air an air purifier can clean and deliver in a set period. The measurement typically used for CADR is CFM, or cubic feet per minute. A higher CADR in CFM indicates the purifier delivers more clean air.

CADR is calculated by considering both the filter efficiency and the airflow through the filters, making it a much better metric (and the standard for air purifiers) than airflow alone. Most CADR tests use a room of around 30m3 and test how much faster the purifier removes particles from the air than if they were left to settle naturally without any other influences.

So, what is the CADR of the 3Pro? It is quite impressive, 413cfm (702 m3/h) at full speed. To best put this in perspective, I recommend reading the fantastic HouseFresh review to see how it compares to other devices currently on the market (spoiler alert; it performs very favourably). I also believe these official figures, as multiple other sources have confirmed them.

The AirFanta 3Pro uses HEPA H11 filters, which are rated to provide ≥ 95% filtration. It’s worth noting that while this figure may not seem that high and that while many air purifiers use higher-rated filters, the H11 filters used here aren’t necessarily bad. That is because, unlike respirators and masks, air purifiers are not designed to purify the air as best possible on a single pass. Rather, if an air purifier can continually filter the same air after multiple passes through the filter, the particle count and concentration will be significantly reduced.

This is important to note because H11 filters are less dense, allowing for better airflow and generally with less noise. Compared to masks, you can think of the balance between filtration and breathability – generally, the more filtration a mask or respirator provides, the less breathable it is. The same goes for air purifiers. The key difference here is that purifiers are designed to have air pass through them multiple times, unlike a mask or respirator, which only has one chance to filter the air before the wearer breathes it. This is why, despite having ‘only’ an H11 filter, the 3Pro can achieve a fantastic CADR.

Of course, this is a very simple explanation, but it’s important to clarify this because I can predict many questions asking, ‘But why weren’t better filters such as HEPA H13 filters used?’. While I can’t speak for the exact answer (you’d have to ask Adam from AirFanta about that!), it’s likely to strike a balance between single-pass filtration performance, airflow, and noise level. While we’ll dive into it soon, I believe complaints about the H11 filter will quickly disappear once you see the performance that the AirFanta 3Pro has to offer.

It’s also worth noting that carbon filters are available, which will provide filtration through adsorption for VOCs and many odours. While I didn’t get these filters to test, some people will opt for them to help manage VOCs. Since these add another layer to the filter, they will likely slightly drop the CADR, but probably not enough to make any significant impact (and, of course, the extra filtration is a big benefit).

AirFanta also has a full list of third-party certifications and test results, which can be viewed here. Interestingly, both bacterial efficiency and viral efficiency reports from Guangzhou Institute of Microbiology Group Co., Ltd. (a CNAS-accredited laboratory) have been provided, and both reports show a > 99.99% decrease in particle concentration after 60 minutes of use in a 30m3 room. The bacterial test goes further and shows the results after 15 minutes, 30 minutes, and 45 minutes. These results show a ≥ 95.63%, ≥ 99.91% and 99.99% drop in tested particles, respectively.

These results show that, at least in a room around 30m3 in size, the AirFanta 3Pro can reduce bacterial and viral particles by ≥ 99.9% in 30 minutes, with 60 minutes seeing a near complete removal of such particles. While we can’t tell exactly what size the particles were in this testing (at least not without paying for access to the original standards), these results are very promising. Potentially worth noting is that since the 3Pro is rated for 702 m3/h, there would have been around 23 air changes within one hour in the 30m3 test chamber. Therefore, the ≥ 95.63% is after almost six air changes, and ≥ 99.91% after around 12.

Of course, these tests and the stated CADR are at the device’s maximum fan speed, which isn’t ideal in many situations. While it’s important to know a device’s maximum performance when needed, it’s more likely you’ll want to leave the device running at a lower speed either all the time or at least quite regularly. Below are the stated CADRs at different fan speeds:

6 – 413CFM 5 – 374CFM 4 – 321CFM 3 – 247CFM 2 – 141CFM 1 – 57CFM Of course, I was also curious to run some tests myself, but I must make the disclaimer that my tests are far from scientific. That said, I wanted to perform some testing similar to a real-life setting where the AirFanta 3Pro is likely to be used. As such, I decided to set up a test room. I measured this room to be 25.6m3, which is about the size of a standard bedroom (it is a bedroom!). While this room is smaller than what I believe this device is intended for, it’s the most controllable room in my house regarding airflow as it only has one door and one window, which can easily be closed and no other forms of ventilation or air disturbances.

In this room, I burned incense until I reached a PM2.5 concentration of 500ug/m3. However, since I can’t exactly control the PM concentration, it ended up being somewhere between 500 and 600 in my tests. I then put the incense out and did a control test to see how long it took the particles to settle without any assistance at all. This took around 90 minutes, and I used this as my baseline.

I monitored the particle concentrations with five AirGradient monitors that were located in each corner and the centre of the room. I then reran this experiment three more times – once with the purifier at maximum speed, once at half speed, and once at the minimum speed to see how long the concentration took to reach < 5ug/m3. I measured the particle concentration by averaging the data from all five monitors to ensure the whole room had been filtered. Here are my results.

In this graph, you can see the baseline data in blue (labelled Ambient) and the particle concentration drop from the AirFanta 3Pro at maximum speed (speed 6) in red. As you can see, it took around 90 minutes for the particle count to drop to < 5ug/m3 without the purifier running but less than 20 minutes with the device at maximum speed. I was very impressed by these first results, and while I wouldn’t want to run the device at full speed often as it is loud, I appreciate having a good peak performance for times when you need to clean the air in a room quickly.

I reran this test, but this time with the 3Pro at half speed (speed 3) and was impressed by the relatively low performance drop. I was worried my results were incorrect, and I reran this three times, but each result was within one minute of the initial result. It looks like a large chunk of the device’s performance is retained between the higher speeds, even though the noise level decreases significantly. This gave me high hopes for the 3Pro’s performance at minimum speed.

Unfortunately, but perhaps not unexpectedly, the device performed far worse at the lowest speed (speed 1). While the particle concentration did drop more quickly than without the device, it was vastly slower than at the faster speeds. It is worth noting that this is not bad at all, as the device is very quiet at this speed and we can see the performance is clearly there, if needed, just turn the device to a higher speed. However, I had inflated hopes after seeing the great performance at higher speeds. Of course, this does match with the stated speed 1 CADR which is roughly 1/8 of the maximum CADR at speed 6.

If we add the times it took the 3Pro to reduce the PM concentration to below 5ug/m3 at each speed setting, we can see that it took between 17.3 minutes and 80.1 minutes to clean the room, depending on the speed. Interestingly, between the higher speeds (speeds 3-6), there appears to be little performance drop-off but a significant improvement in noise levels. At the slow end, the device takes a long time to filter the room, and if you want to use these near-silent speeds, you will probably want to have the device constantly on.

It’s worth noting that previously, the AirFanta 3Pro came with a voltage dial on the adapter. This could be used to adjust the speed, and many reviews of the device still refer to this voltage dial (essentially, a speed dial). Newer versions come with a speed dial with speeds 1-6, so I have referred to speeds instead of voltages for this section.

Before concluding this section, I was also curious how this device would perform if I lit incense in the room while the air purifier was on. I didn’t have a reason for doing this other than curiosity. Still, considering the stellar performance at the higher fan speeds, I wondered how the purifier would handle a pollutant source emitting particles while the device was running. Below, you can see the results (keeping in mind that this same room reaches over 1000ug/m3 when burning incense without an air purifier).

As you can see, the AirFanta 3Pro significantly reduced the maximum particle concentration in the room and rapidly cleaned the air once the incense finished burning. I would be very confident using a device such as this even during periods of heavy pollution, such as during wildfire season.

Overall, I’m quite impressed with the performance of the AirFanta 3Pro, and although it’s loud at full speed, it’s great to know that it’s more than capable of cleaning a small to medium-sized room quickly when needed. Larger rooms will take longer to filter, but I am confident this device can do it based on this performance.

If you prefer a quieter device, you can still use the AirFanta 3Pro, but you will want to leave it at a lower speed and constantly have it on. Thankfully, at the lower speeds, it’s a relatively quiet device, and I found it easy to work even with the purifier constantly on – as long as it was set to a lower speed, such as 1 or 2.

On the certifications page (located here), AirFanta also discloses and publically makes its results from non-performance-related certifications publicly available. There are a few pertinent and important documents here, so let’s discuss these before moving on. For the 3Pro, we can find the following documents provided:

UL507 certificate of AirFanta 3Pro CE-EMC certificate of AirFanta 3Pro and 4Lite CE-LVD certificate of AirFanta 3Pro and 4Lite FCC certificate of AirFanta 3Pro and 4Lite California Air Resources Board certification of Airfanta 3Pro Let’s review these individually, beginning with the UL507 certificate at the top. This certification might seem minor, but this is a safety standard for low and mid-powered fans such as those in PCs, kitchen hood vents, and, obviously, some air purifiers. The documentation for this certification is extensive (around 200 pages long), but this certification ensures the fans on the 3Pro are safe from a range of potential issues.

The next two certifications, both CE certificates from the European Union, indicate that the device meets EMC (electromagnetic compatibility) and LVD (low voltage directive) requirements. These are essentially further safety tests and indicate that the device is safe and provides high protection from potential EMC and LVD dangers.

The FCC certificate shows that the AirFanta 3Pro complies with FCC requirements, which are pertinent to customers from the United States. Still, these certifications are also helpful for trust-building with global customers. While I’m not U.S.-based, I certainly feel more confident in a product if it’s also FCC-compliant.

Finally, the CARB (California Air Resources Board) certification shows that the AirFanta 3Pro complies with California’s electrical safety and ozone requirements. This is particularly important as ozone can be a big issue with some air purifiers, and it’s reassuring to know that this is not an issue in the case of the AirFanta 3Pro.

If you’ve ever seen a CR Box, you will already know exactly what to expect from the 3Pro because that’s exactly what it is – a CR Box with pre-chosen parts that come as one ready-to-assemble package. While CR boxes aren’t that hard to assemble, the 3Pro streamlines the process and removes the difficulty of selecting and choosing your own parts. While some enthusiasts might opt for another CR Box, many other prospective customers will appreciate this approach.

When you open the 3Pro’s box, you will be met with six ‘layers’ that must be assembled. This is a very clean approach, as it means that the packaging for the device is relatively compact (albeit still quite heavy), and it even means that the device can be transported and reassembled easily. While it would be a stretch to call this device portable (that’s what the AirFanta 4Lite and SmartAir QT3 are for!), this means it is far more compact than other air purifiers with similar CADRs. While it is still quite large, you could easily take it on the road and use it at hotels, or perhaps even fly with it if you are taking large suitcases.

Back to actually assembling the product! Once you open the box, you will see six panels layered on top of one another. These are the cube’s six sides, with four being HEPA filters, one being a solid plastic base for the device, and the final being the top, where the four fans are located. Assembling the device is easy, and you will want to place the base on the ground before slotting the four filters into it. The only potential difficulty with assembling this purifier is holding the four sides in place as you slot the top on, but even this is quite straightforward with the included velcro intended for exactly this purpose.

A manual is included, but the device is so easy to put together and take apart that I can’t imagine anyone ever using it past the first assembly. Even then, it’s not really needed, as assembling the device is quite self-explanatory. The only note I think might be important to the user is that the mesh surface on the filters should be facing outwards (not the filtering surface, which should face inwards).

All of this is to say that assembling the device is very straightforward, and no one should be scared away or turned off this device because it has a small DIY element. It’s also a bit easier to assemble than other CR boxes as the slots have already been cut out of the base plate, and everything can be put together without the need for glue, tape, or other materials. Perhaps more helpful, the filters have already been chosen, and there is no need to shop around for the best price-performance filter.

Once assembled, the device takes the shape of quite a compact CR Box. On top of that, I must add that I think this device also looks a lot better than any traditional CR Box – at least any that I’ve ever made! While it still has an industrial look, it’s a device that could quite easily fit into a classroom, office, or room without attracting too much attention. While I value aesthetics much less than performance, I appreciate having a device that looks good, too – especially if it can blend in.

Once assembled, the device feels quite solid, and despite there being no adhesive or tape used in the assembly of the purifier, I feel confident lifting it and moving it without dislodging the pieces. With that said, I tend to lift the device from the bottom and hold the top down to ensure none of the pieces slide out from their intended positions.

On top of the purifier are four large fans connected to a controller that will allow you to adjust the speed of the device. These fans look almost identical to large PC fans, and they’re held in place by a wire bracket that also serves as an extra layer of protection to stop any children or animals from getting fingers or paws into the fans. That said, if you have the device around children, you may want to place it up higher so they can’t easily reach the fans.

That’s really all there is to the design of this device. It’s very simple, but it’s also affordable and performant. While some might miss the smart features and connectivity of more pricey air purifiers, the two types of devices cater to very different customers. Overall, I’m a fan of this straightforward approach, which reminds me of the SmartAir Sqair.

The AirFanta 3Pro uses four 140mm fans to push air through the filters. Characteristically, smaller fans tend to have higher-pitched sounds than larger fans and the AirFanta 3Pro sits somewhere in the middle as it uses medium-sized fans. If you have a desktop PC with a case fan (not the other fans, such as the higher-pitched CPU fan), you’ll likely already know what these fans sound like, as most desktop cases use 120mm or 140mm fans. This isn’t an unpleasant sound, but it is quite audible.

To see how loud the AirFanta 3Pro is, I conducted noise tests at 30cm and 2 metres with a sound level metre that measures in dBA (A-weighted decibel). dBA differs from traditional dB because it is adjusted for the human ear’s sensitivity to different frequencies. Low and very high frequencies are de-emphasized, mimicking how humans perceive loudness. In other words, it’s a better representation of the actual noise level than dB for a device such as an air purifier. However, I do want to note this as many other websites use dB, which will explain why my results are significantly different.

For further context, here are a few examples of the volumes of some noises in dBA. Obviously, these can vary, and especially with dBA, they will vary between different devices. However, they are rough examples:

10 dBA – Breathing or leaves rustling: Extremely quiet. 30 dBA – Whispering: Comparable to a quiet library. 40 dBA – Refrigerator hum: A typical low background noise. 50 dBA – Moderate rainfall: Light, soothing noise. 60 dBA – Normal conversation: The sound of talking at a close distance. 70 dBA – Vacuum cleaner: Considered moderate noise, can be annoying over time. 80 dBA – Heavy traffic or a loud alarm clock: Noise becomes uncomfortable after prolonged exposure. As you can see, at the lowest speeds, the 3Pro doesn’t add much to the noise of most rooms, but at the highest speeds, it can sound almost as loud as a vacuum cleaner (provided you are close to it). This is a lot of variation, but I like how this device gives the user full control over speed and noise, allowing them to pick a good balance.

I think most people will have this device running on speed 2 or 3, and both sounds are very manageable at a distance. If you do want a short burst of cleaning, the device will be significantly louder, and that’s why I only recommend using the higher speeds when needed.

When it comes to power consumption, the device can go from very low power to relatively high power. Here is a list of the wattage and voltage at each fan speed:

6 – 33.2 watt – 12v 5 – 27.4 watt – 11v 4 – 18.9 watt – 9.3v 3 – 11.1 watt – 7.3v 2 – 4.7 watt – 4.8v 1 – 2.2 watt – 3.0v I won’t dive into power costs here because those vary greatly depending on where you reside, but I hope these specifications can give some insights. What’s most impressive to me is how much range this device has, whether we are discussing volume or power draw. There is such a large range that you can choose exactly what setting works best for you and leave the device to it.

The AirFanta 3Pro costs $149 or $159 (USD) depending on whether you opt for the CE-certified or CARB-certified version (the CARB variant is the lower priced of the two). It’s surprising to see a different price on these two units, but I assume it’s due to extra costs, either with the CE certification or getting the device into Europe. Either way, if you’re in the U.S. (or any non-EU country), the CARB variant will work, and that’s the model I received.

In the box, you will get six panels to assemble the 3Pro. This includes four HEPA H11 filters, which, as per AirFanta, should be good to last 6-12 months, depending on air quality conditions. In most cases, I would assume these filters will last closer to 12 months, but those who experience severe wildfire seasons or whose homes are exposed to consistent year-round pollution may need to replace the filters more regularly.

When you need your first filter replacement, you can opt for the default H11 filters or H11 filters with activated carbon. Interestingly, it doesn’t seem you can choose the filters you get with the device initially. If you want activated carbon filters from the get-go, you must purchase the device alongside an extra pack of filters. The activated carbon filters will set you back $74.99 compared to the basic filters, which cost $54.

The filters aren’t cheap, but it’s important to remember that each filter replacement pack you order has four individual filters, which is a substantial amount of filter materials. It’s also important to note that, unfortunately, you will need to purchase official AirFanta filters as they are smaller than most square HEPA filters, and other filters will not fit on this device. I don’t think this is a big deal, as I appreciate the smaller form factor of this device over larger devices, and even four HEPA filters from other brands will not be cheap.

If we estimate that most users use each set of filters for around nine months, your yearly filter costs for non-activated carbon filters will be $67.5. On the other hand, if you opt for the extra VOC adsorption of the carbon filters, you are looking at an ongoing cost of just under $100 per year. This is in a similar price range to other equally performant air purifiers, and this device’s initial cost is also much lower.

While power cost also needs to be factored into the ongoing cost equation, that cost will vary significantly depending on your air purifier usage (hours, speed, etc) and location. However, regardless of usage patterns, you should plan to spend between $67 and $100 on replacement filters for this device every year.

Overall, I’ve been very happy with the AirFanta 3Pro. While it’s not a perfect air purifier – if one even exists – this is a fantastic device that balances many difficult factors. Ultimately, it comes in as an affordable air purifier that doesn’t skimp on performance. In fact, it has a higher CADR than many more (and much more) expensive air purifiers. Furthermore, it offers a wide range of speeds that allow the user to choose the ideal balance between speed and sound for the setting.

I’ve always been a fan of the CR box concept, but I think the AirFanta 3Pro takes this a step further and, due to this, will appeal to many more people. While I’ve never had an issue constructing CR boxes, I often have difficulty sourcing the parts (especially good filters), and I appreciate how the 3Pro can provide the same or better performance at a slightly higher price while also simplifying the shopping process for me.

Surprisingly, for a device of this size, it’s also quite portable, and you will be hard-pressed to find anything that provides a higher CADR than this device while also being ‘packable’. While I still wouldn’t go so far as to say it can fit in a backpack, it can definitely fit in a car or suitcase and is ideal for longer trips where you might be staying in hotels with unknown air quality. If, on the other hand, you want to use it around the house, it’s also a great device.

The biggest disadvantages I see with the AirFanta 3Pro are the sound and the design. There’s no denying that while the device is powerful, it’s also loud at its higher speeds. While this isn’t unusual for an air purifier, it is worth noting that you probably won’t want to run this device at its higher speeds unless necessary. I usually find myself using speed 2 or 3, which is the sweet spot for most users. On the upside, the lower speeds are almost silent, and although they significantly diminish performance, they are good for users who are okay with constantly running the device.

The design may also bug some users. While I don’t mind (and actually like) the device’s industrial design, I know some people don’t use CR boxes due to the design. If you don’t like the look of CR boxes, the chances are you also won’t like the design of this device. With that said, this design allows this device to have such a good price-to-performance ratio, and I think many potential customers will appreciate this more.

Overall, the AirFanta 3Pro is a cost-effective air purifier that should be on your radar – especially if price is a concern. If you’ve tried the 3Pro, I would love to hear your thoughts, so please feel free to use the comments section below! Furthermore, if you have any remaining questions, please don’t hesitate to as,k and I will do my best to reply. Thank you for reading.

Pros: High CADR (413 cfm) for effective air purification Affordable compared to similar high-performance devices Pre-assembled CR box design simplifies setup Portable and compact for travel use Certified for safety (UL507, CE-EMC, FCC, CARB) Cons: Loud at higher speeds Design may not appeal to all users (industrial look) Limited to proprietary filters, increasing costs No activated carbon filters included in basic kit

Note

question on the air purifiers! when they give the square footage do they only mean it in like one open space or throughout multiple rooms? my whole house is maybe 900ft². could I get say one airmega 250 and just put it in the central hall (living room/kitchen is on one end and the bedrooms and bathroom are at the other end) or would I need to get like a unit for each room?

With the disclaimer that I am not an expert in air purification and have not had the time or energy to research this as much as I'd like, the short answer to your question is that you'd probably want multiple air purifiers (or a much bigger/better one) for your space. The long answer is that there are several factors you'd need to take into account when choosing a purifier, including:

Air Changes per Hour (ACH): When air purifier companies list a unit's square foot coverage, almost all of them (including Coway) list the coverage for one air change per hour at the highest fan speed. Especially if your goal is to reduce the concentration of airborne viruses in your space, you want 4-6 ACH at minimum. The Coway Airmega 250 can offer 1 ACH at 1,860 sq. ft., 2 at 930, and 4 at 465. This means it does an amazing job of filtering the air in my 120 square foot office, but you'd probably want at least two of them in your 900 square foot living space. (Note: Your HVAC system will also contribute to the overall ACH in a space, though you may not have access to all the data needed to calculate how much air it's moving or how good the filter is.)

Clean Air Delivery Rate (CADR): CADR/CFM math makes my brain hurt, but essentially, CADR is basically a reflection of the air flow (CFM) times the efficiency of the air filter. It's a measure that makes it easier to compare air purifiers without being misled by marketing (see above). Generally, you want a filter with a CADR that equals at least two-thirds of a room's area, and a smoke CADR (if provided) is the best proxy for a filter's ability to clear virus particles from the air. The Airmega 250's smoke CADR is 249, meaning it'll be most effective in a room no larger than 370-ish square feet.

Noise: CADR and ACH tend to be measured based on the device's highest fan speed. In my personal experience, most decent air purifiers with multiple speed settings are near-silent at level one, audible but tolerable at level 2, and sound like jet engines at level 3+. Coway is not exempt from this judgment, though I've found their purifiers to be quieter than most for their size. Unless you are profoundly unbothered by white noise, you'll likely want to run the purifier below its max fan speed, which means you can expect slightly lower CADR and ACH than advertised.

Unit Position (and walls): Air purifiers are most effective if you place them near the middle of an open space, as opposed to in a corner or near a wall. If your house is essentially an open-concept square, one purifier in a central area (maybe something a little heftier than an Airmega 250) might be sufficient to rid the air of most allergens and provide some protection from airborne viruses. However, if you have a lot of walls and doors and/or want better protection, you're better off getting a couple of purifiers and spreading them out.

I hope this info is helpful! It's a bummer that adequate air filtration is so expensive, but at the end of the day, even one decent-sized purifier in one section of your house will make some measurable difference in your health and well-being. And if your primary concern is COVID, not environmental allergies or air pollution, remember that opening windows is free!

Choosing the Right Industrial Fan and Blower for Malaysian Factories

In Malaysia’s industrial landscape, where heat, humidity, and airborne contaminants often challenge operational efficiency, the role of industrial fans and blowers is crucial. Whether it's for ventilation, cooling, drying, or air pollution control, selecting the right fan or blower can dramatically improve working conditions, protect equipment, and boost overall productivity.

This guide will help Malaysian factory managers and engineers make informed decisions when choosing industrial fans and blowers for their facilities.

Understanding the Difference: Fans vs. Blowers

Although the terms are often used interchangeably, fans and blowers serve different purposes.

Industrial Fans: These move air at relatively low pressure and high volume. They're typically used for general ventilation, cooling, and air circulation in factories.

Industrial Blowers: These are designed for higher pressure applications and are used where airflow needs to overcome resistance, such as in ducted systems, combustion air supply, or dust collection.

Knowing the fundamental difference is the first step to selecting the right equipment.

Key Factors to Consider When Choosing

1. Application Needs

Different industries require different types of airflow. For example:

Electronics factories require clean, cool air to prevent overheating.

Food processing plants may need humidity control and odour removal.

Chemical plants must manage fumes and hazardous gases.

Start by evaluating your factory’s specific air movement requirements—whether it's cooling, exhaust, dust removal, or process air.

2. Airflow and Pressure Requirements

Understanding how much air needs to be moved (measured in CFM—cubic feet per minute) and at what pressure (measured in static pressure or Pascals) is essential. Malaysian factories operating in high-temperature environments may need fans with high airflow, whereas operations involving ducts or filters may require blowers with higher pressure ratings.

Consult with an HVAC engineer or use fan selection software to calculate accurate specifications.

Types of Industrial Fans and Their Uses

Industrial ventilation systems must comply with safety and environmental standards set by DOSH (Department of Occupational Safety and Health) and DOE (Department of Environment). Ensure the fan or blower system meets local guidelines for:

Noise levels

Emission control

Workplace air quality

Check for product certifications or approvals to ensure compliance with these regulatory requirements.

Conclusion

Choosing the right industrial fan and blower for your Malaysian factory is not a one-size-fits-all decision. It requires careful consideration of the application, performance requirements, environmental factors, and compliance standards. Investing in the right system can significantly improve air quality, employee comfort, safety, and energy efficiency—key drivers of productivity in today’s competitive manufacturing landscape.

Working with reputable suppliers in Malaysia who understand local industrial needs can make all the difference. With proper selection and maintenance, your fan and blower systems will serve your factory efficiently for years to come.

Investing in a laser cutting machine is a major decision for any shop or manufacturing operation. While the sticker price of a new SLTL cutting machine ranges from USD 90,000 to USD 250,000 depending on power and bed size, the true cost of ownership extends far beyond that initial purchase. In this article, we’ll break down the key factors—purchase price, installation expenses, facility requirements, operating costs, consumables, maintenance, and depreciation—to help you calculate total cost of ownership (TCO) for a laser cutter in the USA.

1. Initial Purchase Price

SLTL cutting machines come in a variety of configurations. Entry-level systems (1 kW–2 kW, 4 ft × 4 ft beds) typically start around USD 90,000. Mid-range machines (2 kW–4 kW, 4 ft × 8 ft or 5 ft × 10 ft beds) run from USD 120,000 to USD 160,000. High-end systems (6 kW–12 kW, 6 ft × 12 ft or 8 ft × 20 ft beds) can exceed USD 250,000. Factors that influence price include:

Laser Power (kW): Higher power means faster cutting and thicker-plate capability but costs more.

Bed Size (ft × ft): Larger beds require more steel and larger motion systems, increasing frame and gantry costs.

Automation and Material Handling: Features like automatic sheet loaders or robotic unloaders can add USD 20,000–USD 50,000.

Control Software and Optics: Advanced nesting software, IoT monitoring, and premium optics packages add another USD 5,000–USD 20,000.

Brand, Warranty, and Service: SLTL machines include standard warranties, but extended warranties and nationwide service contracts add USD 10,000–USD 20,000 annually (Source: https://www.laseruser.com/laser-equipment/laser-cutting-machines-pricelist/ and https://www.sltl.com/en-in/products/laser-cutting-machine-fiber).

. Installation and Training

Once the machine is purchased, installation and training costs must be factored in:

Site Preparation: You may need concrete floor reinforcement, a dedicated 3-phase electrical cut-in (480 V), and compressed-air hookups. Costs can range from USD 5,000 to USD 15,000, depending on local contractor rates and the complexity of electrical upgrades.

Machine Setup and Calibration: Professional installation by factory-trained technicians typically runs USD 5,000–USD 10,000. This includes leveling, alignment, testing, and basic adjustments to ensure optimal cut performance.

Operator and Maintenance Training: On-site training for operators and maintenance staff adds USD 3,000–USD 7,000. Comprehensive training cuts down learning curves, reduces early-stage errors, and improves uptime (Source: https://www.sltl.com/en-in/services/laser-machine-installation-training).

3. Facility and Utilities

Laser cutters have specific facility requirements beyond standard workshop space:

Space Requirements: A 4 ft × 8 ft laser table needs roughly 15 ft × 20 ft of clear floor area for the machine, operator access, and material handling. Larger machines (6 ft × 12 ft beds) require 20 ft × 30 ft or more. Real-estate costs vary widely; in some regions, industrial rent can exceed USD 1.50 per square foot per month.

Electrical Consumption: A medium-duty 2 kW fiber laser system typically consumes 25–30 kW during cutting. Running an 8 hr shift at USD 0.10 per kWh equates to about USD 20–USD 24 daily in electricity. Over 250 operating days, that’s roughly USD 5,000–USD 6,000 per year. Higher-power lasers (6 kW–10 kW) can double or triple those figures.

Cooling and HVAC: Fiber lasers use closed-loop water chillers or industrial chillers. A dedicated chiller can consume 5 kW–10 kW continuously, adding another USD 1,000–USD 2,500 annually in electricity. HVAC modifications—such as increased air conditioning capacity—can add USD 3,000–USD 8,000 to initial capital costs.

Fume Extraction: Proper ventilation is mandatory. A 600–800 CFM extraction unit with multi-stage filters costs USD 2,000–USD 5,000. Annual filter replacements and duct cleaning add USD 1,000–USD 2,000 per year (Source: https://www.accurl.com/blog/fiber-laser-cutting-safety/).

4. Consumables and Operating Costs

Your laser cutter relies on various consumables that wear out or require regular replacement:

Nozzles and Protective Glass: Nozzles typically last 100–300 hours depending on material and power settings. At USD 100–USD 200 per nozzle, and assuming 2–3 nozzles replaced monthly, that’s USD 2,400–USD 7,200 annually. Protective cover glasses run USD 50–USD 100 each; you may change one per month, costing USD 600–USD 1,200 per year.

Focus Lenses and Mirrors: OEM focus lenses cost USD 1,000–USD 2,000 and often last 800–1,200 cutting hours. Plan on one replacement every 5–8 months in heavy use, i.e., USD 1,500 × 2 = USD 3,000 annually. High-quality mirrors also degrade, costing USD 1,500–USD 2,500 each; replacing mirrors once a year could add USD 1,500–USD 2,500.

Assist Gases: Cutting mild steel usually uses oxygen; stainless steel and aluminum require nitrogen. High-purity nitrogen (99.998 percent) costs USD 1.50–USD 3.00 per cubic foot. A 2 kW system might use 50–100 scfh during cutting. Over 2,000 cutting hours, that equates to USD 9,000–USD 18,000 annually. Some shops use nitrogen generators to reduce costs, but generator capital can be USD 20,000–USD 40,000 with maintenance expenses.

Electricity for Running the Laser Source: As covered above, estimate USD 5,000–USD 6,000 per year for a 2 kW system; a 6 kW system could consume USD 15,000–USD 18,000 yearly.

Combined annual consumable and operating costs for a mid-range 4 kW laser could reach USD 30,000 or more (Source: https://www.laseruser.com/laser-equipment/laser-cutting-machines-pricelist/).

5. Maintenance and Service Contracts

Regular maintenance keeps your machine running reliably, but it carries its own costs:

Preventive Maintenance Visits: Factory technicians typically charge USD 1,500–USD 3,000 per visit, and recommended schedules are twice a year for medium-use machines. That’s USD 3,000–USD 6,000 annually.

Spare-Part Kits: Annual spare-part kits (including O-rings, seals, sensors, filters) cost USD 2,000–USD 5,000 depending on machine complexity.

Service Contracts: Extended service agreements covering travel, labor, and parts often start at USD 10,000–USD 20,000 per year. These contracts guarantee response times (4 hr–8 hr) and may include software updates, on-site repairs, and wear-part discounts.

If you skip a service contract, unplanned service calls can cost USD 5,000–USD 10,000 per visit, plus lndustrial Laser Cutting Machines | USA Sheet Metal Cutter

6. Depreciation and Financing

The capital cost of a laser cutter is depreciated over its useful life (5–7 years for tax purposes). Depreciation expense can be USD 15,000–USD 50,000 per year depending on machine price. If financed, interest charges add to overall cost:

Depreciation (Straight Line): A USD 150,000 machine depreciated over 7 years yields an annual depreciation of USD 21,428.

Lease or Loan Interest: If you finance USD 150,000 over 5 years at 5 percent interest, total interest paid is approximately USD 20,000, or USD 4,000 yearly (Source: https://www.sba.gov/funding-programs/loans).

Thus, annual non-cash costs (depreciation + interest) for a USD 150,000 machine could be USD 25,428.

7. Total Cost of Ownership (TCO) Example

To illustrate, consider a mid-range SLTL 4 kW, 5 ft × 10 ft machine purchased at USD 160,000. Below is a rough TCO estimate for Year 1:

Annual Cost Breakdown:

Depreciation (7 years): $22,857

Loan Interest (5 years at 5%): $3,000

Electricity (20 kW average draw): $10,000

Chiller Electricity (7 kW): $2,500

Assist Gas (Nitrogen + Oxygen mix): $12,000

Nozzles and Cover Glass: $4,000

Focus Lenses and Mirrors: $4,500

Filters, Seals, and Other Consumables: $3,000

Preventive Maintenance Visits: $5,000

Service Contract: $15,000

In this example, the first-year TCO approaches USD 260,357—well above the USD 160,000 purchase price. Subsequent years (excluding installation and facility mods) may run roughly USD 80,000–USD 100,000 annually depending on usage (Source: https://www.accurl.com/blog/fiber-laser-cutting-safety/ and https://prathamtech.com/blogs/use-original-spare-parts/).

8. Optimizing Your TCO

Match Power to Your Needs: Avoid over-specifying power. A 2 kW system may suffice if you rarely cut beyond 12 mm steel.

Invest in Automation: Higher upfront costs for loaders and part unloaders pay off if labor is expensive and you need high uptime.

Budget for Consumables: Negotiate bulk-purchase discounts on nozzles, lenses, and filters. Consider nitrogen generators if cutting large volumes of stainless.

Schedule Preventive Maintenance: Stick to OEM recommendations to prevent costly unplanned repairs.

Monitor Energy Usage: Use variable frequency drives (VFDs) on chillers and ensure proper system insulation to reduce power draw.

Conclusion

The real cost of owning a laser cutter in the USA extends well beyond the purchase price of USD 90,000–USD 250,000. When you factor in installation, facility upgrades, utilities, consumables, service contracts, depreciation, and financing, annual TCO can exceed USD 80,000–USD 100,000 for a mid-range system. Careful planning—matching machine power to your application, investing in preventive maintenance, and managing consumable usage—will help you optimize your investment and ensure a strong return over the life of your SLTL laser cutting machine.

Choosing the Best Air Breather Filter for Industry

How to Select the Right Air Breather Filter for Industrial Use

Industrial hydraulic systems face harsh operating environments and high demands for performance and reliability. In such settings, even the smallest component can make a major impact—and air breather filters are a prime example. These filters play a crucial role in keeping contaminants out of hydraulic reservoirs, maintaining fluid cleanliness, and preventing costly system failures.

At Techknow Engineering Enterprise, we've seen far too many equipment breakdowns traced back to the wrong or neglected air breather filters. Selecting the correct breather for your specific application isn't just good practice—it's essential. The right filter extends equipment life, reduces downtime, and safeguards your investment in high-performance machinery.

Let’s explore the key considerations to help you choose the ideal air breather filter for your industrial operation.

Understand the Role of Air Breather Filters

First, it’s important to grasp what air breather filters actually do. As hydraulic systems operate, fluid levels in the reservoir rise and fall due to thermal expansion and system movement. This causes air to move in and out of the reservoir. Without proper filtration, airborne contaminants like dust, dirt, and moisture can enter the system during this process.

Over time, these contaminants degrade the hydraulic fluid and cause wear on pumps, valves, and seals. Air breather filters act as the first line of defense—removing particles and, in some cases, moisture from incoming air to keep the system clean.

Techknow Engineering Enterprise always starts system diagnostics by evaluating filtration quality—because contamination is often the root cause of failures.

Assess Environmental Conditions

Your operating environment should guide your filter selection. Not all air breather filters are created equal, and using the wrong type can do more harm than good.

Dusty and Dirty Environments

If your facility or field equipment operates in dusty areas—such as mining, construction, or agriculture—you’ll need filters with a fine particulate rating. Look for filters that can trap particles as small as 3 to 5 microns.

High-Humidity or Marine Settings

In humid environments or near saltwater, standard breather filters won’t suffice. You’ll need desiccant air breather filters, which absorb moisture before it reaches the reservoir. These are ideal for offshore rigs, shipyards, and open-air storage tanks.

At Techknow Engineering Enterprise, we recommend desiccant models with color indicators so users can easily monitor saturation and schedule timely replacements.

Consider Flow Rate and Reservoir Size

The capacity of the air breather filter must match the airflow requirements of the system. Undersized filters can restrict air exchange, creating vacuum pressure in the reservoir that stresses seals and reduces performance.

Check the reservoir’s displacement volume and select a filter that allows for adequate airflow during peak operation. Most manufacturers provide airflow ratings in cubic feet per minute (CFM) or liters per minute (LPM).

Our experts at Techknow Engineering Enterprise help clients calculate proper sizing to avoid the common mistake of overloading a filter beyond its capacity.

Match Filter Mounting to System Design

Compatibility with your reservoir is crucial. Air breather filters come in various mounting styles:

Threaded: Most common for industrial tanks, offering secure attachment.

Bayonet: Quick-release type for easy maintenance.

Flanged: Used on larger systems or in high-vibration environments.

Techknow Engineering Enterprise can customize mounting adapters when clients need to upgrade filtration systems without altering their existing tank designs.

Choose Between Standard and Desiccant Models

Deciding between a standard particle filter and a desiccant model depends on your specific risks.

Standard Filters: These remove airborne dirt and dust. Suitable for indoor use or controlled environments.

Desiccant Breathers: These include a moisture-absorbing gel, typically silica-based. The gel changes color as it absorbs water vapor, providing a visual signal for replacement.

For most outdoor or variable-climate industrial applications, desiccant air breather filters offer superior protection and peace of mind.

Techknow Engineering Enterprise maintains a full inventory of both types and helps clients decide based on their exact needs and budget.

Evaluate Maintenance Requirements

Different air breather filters have varying maintenance intervals. Some are disposable, while others are serviceable or refillable.

Disposable Filters: Easy to replace but generate recurring costs.

Refillable Desiccant Filters: Economical over time but require manual replacement of the desiccant beads.

Spin-On Types: Like automotive filters, these are easy to remove and replace during routine servicing.

We recommend setting up a maintenance schedule based on system hours, environmental exposure, and manufacturer guidelines. At Techknow Engineering Enterprise, we also offer preventive maintenance kits and training for in-house teams.

Factor in Cost vs. Performance

While cost is always a consideration, cutting corners on filtration is a gamble. A low-cost filter may not offer sufficient protection, leading to contamination that damages components worth tens of thousands of rupees.

Always weigh the cost of the air breather filter against the potential cost of downtime, part replacement, and fluid changes. In our experience at Techknow Engineering Enterprise, clients who invest in higher-quality breathers save significantly in the long run through improved system uptime and fewer repairs.

Choosing the right air breather filter isn’t just about plugging a hole in your reservoir. It’s about engineering your system for optimal protection and performance. With guidance from Techknow Engineering Enterprise, you can ensure your filtration solution matches your industry’s demands, keeping your hydraulic systems running smoothly and efficiently.

Is it like weird that I don't have some fucking divine purpose for going to college. Like my interest that I am pursuing is getting a degree. I'm not here because I'm trying to change the world. Like yesterday I was listening to the WTYP podcast and Mark "Hyce" Huber said that a lot of his friends in mechanical engineering calculate how many CFM of air need to be evacuated from a train tunnel so you don't fucking die from asphyxiation. Like that's the big thing they do. They aren't designing skyscrapers they are calculating how not to kill people, and then getting ignored because doing it right is expensive.

To ensure optimal performance and energy efficiency, it's crucial to prioritize proper installation. Evaporative Cooling Installation Melbourne needs to be handled by skilled professionals, like the team at Hitech Air Solution, who understand the intricacies of the system and can ensure its correctly fitted for maximum benefit.

Factors Influencing Evaporative Cooling Installation Costs

Several key elements determine the final price tag for your evaporative cooling installation. Understanding these factors will empower you to have a more productive conversation with potential installers and secure the best possible deal:

System Size and Capacity: The size of your home and the number of rooms you want to cool will directly impact the size and capacity of the evaporative cooling unit needed. Larger homes require larger, more powerful systems, which naturally translates to higher installation costs. Installers will typically calculate the necessary airflow (measured in cubic feet per minute, or CFM) based on your home's square footage and layout.

Roof Type and Accessibility: Evaporative coolers are typically installed on the roof. The type of roof you have (tile, metal, or shingles) and its accessibility can influence the complexity and therefore the cost of the installation. Roofs that are difficult to access or require specialized equipment for safe installation will likely result in higher labor charges.

Ductwork: The existing ductwork in your home plays a crucial role. If you already have a well-maintained ductwork system, the installation process will be simpler and less expensive. However, if your ductwork is old, damaged, or inadequate for the new system, it may need to be repaired or replaced, adding to the overall cost. New ductwork installation is a significant expense.

Brand and Model: Different brands and models of evaporative coolers come with varying price points. High-end models often boast superior energy efficiency, advanced features, and longer warranties, justifying a higher initial investment. Research and compare different options to find the best balance between price and performance for your needs.

Additional Features and Upgrades: Consider whether you want any additional features or upgrades, such as zoning (allowing you to control the temperature in different areas of your home independently), smart home integration, or advanced filtration systems. These additions will naturally increase the installation cost.

Labour Costs: Labour charges can vary significantly depending on the installer's experience, reputation, and overhead costs. It's wise to obtain quotes from multiple reputable companies to compare pricing and ensure you're getting a fair deal. Always prioritize qualified and licensed technicians.

Permits and Compliance: In Melbourne, you may need permits for evaporative cooling installation, depending on your local council regulations. Factor in the cost of these permits and ensure that your chosen installer is familiar with the relevant building codes and compliance requirements. A reputable installer will handle the permit process for you.

Getting Accurate Quotes and Avoiding Hidden Costs

To ensure you receive accurate and transparent quotes, follow these tips:

Get Multiple quotations: Request at least three quotations from various installers. This allows you to compare pricing and assess the level of service and professionalism offered by each company.

Request a Detailed Breakdown: Ask for a detailed breakdown of the installation costs, including the price of the unit, ductwork modifications (if needed), labor charges, permit fees, and any other associated expenses. This will help you identify any hidden costs or unexpected charges.

Check References and Reviews: Before hiring an installer, check their references and read online reviews to gauge their reputation and customer satisfaction.

Verify Licensing and Insurance: Ensure that the installer is licensed and insured to protect yourself from liability in case of accidents or damages during the installation process.

Ask About Warranties: Inquire about the warranties offered on both the evaporative cooling unit and the installation workmanship. A broad warranty offers peace of mind and protects your investment.

Long-Term Savings and Benefits

While the initial installation cost is a consideration, remember to factor in the long-term savings and benefits of evaporative cooling. These systems typically consume significantly less energy than traditional air conditioners, resulting in lower electricity bills. Furthermore, evaporative cooling uses water as its primary cooling agent, making it a more environmentally friendly option. Investing in evaporative cooling can be a smart move for Melbourne homeowners seeking a cost-effective and energy-efficient way to beat the summer heat. By understanding the factors influencing installation costs, obtaining accurate quotes, and considering the long-term savings, you can make an informed decision that benefits both your comfort and your budget. Remember to choose a reputable and experienced installer like Hitech Air Solution to ensure a seamless and successful installation process.

How to take up perfect the Right Industrial Air Compressor

In industrial operations, efficiency and reliability are essential to success. A well-chosen industrial air compressor can greatly improve productivity while reducing downtime and costs. But how do you choose the right industrial air compressor for your needs? With the various technologies and different types of compressors available, choosing the correct one can be confusing and oftentimes overwhelming. Selecting the perfect industrial air compressor for your application requires careful consideration of several factors. These include the required air pressure, the air volume based on airflow and pressure needs, the level of air quality demanded by your application, energy efficiency requirements, the operating environment, and the intended use in industrial processes. Whether you’re a factory owner, a workshop manager, or involved in heavy-duty applications, understanding these factors will help you get the most out of your investment. Let’s take a look in depth!

What is an industrial air compressor?

An industrial air compressor is a versatile machine that converts power into compressed air, providing energy for various tools, machines, and systems. From powering pneumatic tools to aiding in assembly lines, these compressors are the backbone of many industries. Industrial compressor manufacturers facilitate different types of compressors and sizes, each tailored to specific needs. Understanding their features and benefits is essential for selecting the right one.

A comprehensive guide to choosing the right industrial air compressor
