Making Screw Air Compressors Oil-free

It might be hard to believe but air compressors have been around for thousands of years. The earliest known compressors were bellows, used to blow compressed air into furnaces to stoke up the heat, thereby allowing ancient men to produce stronger and better metals for tools and weapons. >

Following the invention of steam engines, they became a popular method to power air compressors. Subsequently, Internal Combustion (IC) engines began to be used as a power source for operating reciprocating air compressors. Later, as larger industries were established, they demanded more efficient compressors capable of running with minimal maintenance and for longer periods. A rotary air compressor was the answer. Both these types of compressors continued to evolve over time and today, they are both highly efficient and technologically well advanced. Conventional reciprocating air compressors though have certain innate limitations; most notable being that the oil used for lubrication is carried along with the compressed air. Filtering removes much of the oil but not all of it. For example; pre-filters, high efficiency coalescing filters and activated carbon filters remove trapped oil to a great extent.

Oil-free compressed air solutions are used extensively in the pharmaceutical, textile & automotive industries.

But these filters themselves have characteristic limitations. For instance, above 20°C, coalescing filters do not remove fine oil vapours, leaving very fine particles of residual oil in the form of aerosols; and activated carbon filters are not usable at filtration temperatures above 40ºC because the carbon then absorbs the oil vapour, gets saturated, and becomes ineffective. And, filtration itself raises another problem: safe disposal of used filters to avoid environmental contamination. Notwithstanding the environmental issue however, there are several industrial applications that require compressed air that is completely oil-free. Food and beverage, pharmaceuticals, electronics, automotive painting, textiles, paper and cosmetics are typical examples. These applications demand wide operating temperatures of 0-45°C, stringent air purity standards higher than ISO 8573-Class I, high levels of safety, eco-friendly operation and some more. Even the most advanced filtration technology falls short of meeting such exceptional standards of air purity.

Plainly, lubricated compressors were not the answer. It required a radically new technology of air compression. Enter oil-free screw air compressors.

ELGi’s Screw Compressors are designed to save energy and ensure long life.

This inventive machine uses no lubricating oil in the compression chamber and hence delivers compressed air with practically no trace of oil. Additionally, because of the continuous sweeping motion of the screws – two meshing helical screws known as rotors, driven by a pair of timing gears – there is very little pulsation or surging of flow, which occurs with piston compressors. Screw compressors thus deliver smooth, pulse-free compressed air. They also tend to be compact and run smoothly with minimal vibration. Since they also employ a more efficient compression system, they not only reduce energy costs but also enable precise adaptation to end-user requirements based on careful study and analysis of their critical processes and customising with a controlled, total compressed air system, thereby also improving productivity.

Despite all its apparent advantages, oil-free screw air compressors continued to face technological and manufacturing challenges, especially pertaining to the problem of overheating due to the absence of lubricating oil in the compressor chamber. Furthermore, despite being oil-free, there was still the need for filtration as hydrocarbons and other contaminants ingested from the ambient air required to be removed prior to the point-of-use. All this began to affect their popularity to some extent. However, this also prompted a new development: oil began to be injected into the compression cavities to not only aid sealing but also provide a cooling sink for the heat of compression.

In this so-called ‘oil-flooded’ rotary screw compressor, the oil was then separated from the compressed air, cooled, filtered and recycled. The injected oil not only helped in lowering the compression temperature but also captured extraneous particulates from the incoming air, thus effectively reducing the particle loading of subsequent air filtration. Having thus overcome the initial problems that oil-free compressors faced, there was a shift from oil-free to oil-flooded compressors, which then gained popularity.

Oil-Free Two Stage: Air-Cooled Model

But the need for a completely oil-free compressor remained. This was felt keenly in industrial applications where even traces of oil in processed air could be disastrous. For instance, even minute particles of oil in precision electronic circuitry or critical semiconductor components can play havoc with electronic gadgets. Lube oil traces in processed food and beverages mean serious health risks. Pharmaceutical applications demand pristine air too. It is the same with paper mills, textiles, high-gloss painting of automobiles and many others. While Western countries had strict regulations governing the purity of air used in such critical applications, Asian countries including India and China had less stringent rules. But it was only a question of time before they too fell in line. And, although industries continued to rely on filtration to get rid of the entrapped oil, complex filtration equipment added to the cost, created air pressure drops and still did not deliver 100% oil-free air. At ELGi, this presented a situation ripe with potential.

Oil-Free Two Stage: Water-Cooled Model

ELGi embarked on developing the oil-free screw air compressor by obviating the need for oil as a medium to carry away the heat of compression. By early 2005, the first prototype was assembled and tested. And by early 2008, a test compressor was commissioned at a user’s facility for validation. Next year five more were commissioned at different locations. These models completed 10,000 hours of validation. Regular sales began by early 2011. Today, ELGi’s in-house oil-free technology with inter-cooler has been validated in demanding industrial applications for over 150,000 cumulative hours.

Inside the ELGi factory

The fully-packaged ELGi-NE series has models with high volumetric efficiency that deliver from 500 to 1800 cfm (cubic feet per minute) and pressures of up to 10 bars (kg/cm2.) Incorporating superior safety norms, these models not only have low energy losses and low air outlet temperatures but are also energy efficient and compact.

They employ two-stage compression with external water jacket inter-cooling, a unique eta-V profile rotor enabling high swept volume, low operating noise and low vibration achieved by combining radial roller bearings and 4-point axially loaded ball bearings. Innovative features like carbon impregnated SS air seals, helical grooved non-contact bronze oil seals and high-performance Visco-seals at suction and discharge rotor ends, an ingenious process of PTFE and PFA (Teflon) dry lubricant coating on carbon steel rotors, an efficient helix-angled timing gear and robustly designed cupro-nickel intercooler and after cooler, heat exchangers offering superior corrosion resistance and finally optimally designed capacity control valves; all ensure not just high efficiency but safety, durability, easy maintenance and low operating cost.

Compression is also very efficient on account of the precise clearances maintained between the helical rotors and the compression chamber, thanks to the unique eta-V profiles designed by ELGi. This rotor design reduces pressure losses and increases stage efficiencies, leading to an overall increase in adiabatic efficiency.

ELGi builds its own rotor milling machines to ensure quality rotors with lowest manufacturing cost.

Only a handful of companies in the world have this design capability. It is to be noted however, that though the machine is termed an oil-free screw compressor, it applies to only the screw chamber that forms the air compression cavity. Oil is nevertheless used in the machine – to lubricate a slew of components like the capacity control valves, air-end bearings, the timing gears and the air-end stage gear. So even though the rotors and the screw chamber do not use any lubricating oil, there is nevertheless an oil circuit comprising the oil pump, cooler, filter and oil sump. Similarly, there is also a water circuit that supplies cooling water to the intercooler, after cooler, and the 1st and 2nd stage air-ends. For ELGi, this development has been a rewarding experience. Industry watchers have it that globally, ELGi is one of only 5 corporate companies to design and manufacture oil-free air-ends.

What Makes Screw Air Compressors the Preferred Choice for Air Experts?

When seeking the optimal air compressor solution for your operations, it's essential to consider various parameters which extend far beyond the upfront cost. The productivity and effectiveness of your material handling systems, spray painting procedures, and diverse machine tools are heavily contingent upon the compressed air system. Consequently, industry experts often advocate for the adoption of screw air compressors for their exceptional efficiency, continuous operational capacity, reduced noise levels, space-saving design, and reliability.

Air compressors can be broadly categorized into two types: reciprocating and rotary screw compressors. Reciprocating compressors use pistons to compress air, while rotary screw compressors utilize rotating elements to generate compressed air. Among them, rotary screw compressors consist of interlocking helical rotors that compress the air as it moves through the compression chamber, allowing for continuous and efficient operation.

Screw Air Compressors

Screw air compressors are known for their efficiency, reliability, and ease of use. They typically use oil for cooling, sealing, and lubrication within the compressor. These compressors consist of two rotors, often referred to as male and female rotors, which have interlocking helical grooves that reduce the volume of air as it passes through the compression chamber. As the rotors rotate, air is drawn into the chamber, trapped between the lobes of the rotors, and compressed as the volume decreases. The injected oil provides cooling and lubrication, ensuring smooth operation and minimizing wear on the components. The compressed air and oil mixture are then separated, with the oil being cooled and recycled, while the compressed air is discharged.

Types of Rotary Screw Air Compressors

There are two main categories of rotary screw air compressors commonly used in businesses and manufacturing:

Oil-free Screw Air Compressors: These compressors operate without the need for oil lubrication. Instead, alternative lubricants such as PTFE, distilled water, or proprietary coatings are used for lubrication and heat dissipation. Oil-free compressors are essential for industries where even the tiniest trace of oil is unacceptable, such as food and beverage production, pharmaceuticals, packaging, and other sensitive sectors.

Oil-lubricated Screw Air Compressors: In oil-lubricated screw compressors, oil is introduced into the compression chamber to facilitate lubrication and efficient heat dissipation.

Keeping your air compressor cooler clean

Why preventive maintenance pays off when the hot and humid summer weather hits?

With high temperatures and humidity persisting in many parts of Australia, we are currently experiencing a higher call out rate for air compressor breakdowns, stemming from air compressor cooler blockages. However, this unnecessary downtime can be avoided by following one simple rule.

High ambient temperatures created by a hot and humid summer mean your compressed air system has to work harder. If maintenance has lapsed then it’s likely your cooler will be dirty, and a dirty cooler will increase the compressors running temperature, creating an array of issues within your compressed air system, that can ultimately cause the compressor to breakdown, leading to costly unplanned downtime and maintenance.

What are the likely outcomes of an air compressor cooler blockage?

Firstly, this means your compressed air system will be working overtime to maintain required output and have a detrimental effect on the lubricating properties of your oil. This would result in shortened service intervals and additional costs that could be easily avoided.

Secondly, a higher running temperature will increase the amount of oil passed downstream into the reticulation system. This can lead to high differential/early spoilage on plant filtration that will increase energy costs. It will also reduce service intervals and increase the chance of machine breakdown.

However, the other impact that shouldn’t be overlooked is the long-term effect this will have on the lifespan of the air compressor. As we mentioned, a higher running temperature will increase oil carry over and create a lower oil level in your compressed air system. Without adequate lubrication, the internal components of the air compressor will prematurely wear – and even fail. This means that wearing parts will have a shorter life span and need replacing sooner than expected (creating extra expense). It could also cause longer term damage to the compressed air system which significantly reduces its overall useful life, meaning it will need replacing sooner than under normal conditions.

How can this be avoided?

It’s actually quite simple. By following the manufacturers recommended maintenance schedule you can ensure your air compressor cooler is clean and your compressor is ready to handle the higher temperatures and humidity of the summer months. In addition, don’t forget to consult your user manual and perform the daily and weekly checks as prescribed. As they say, an ounce of prevention is worth a pound of cure.

Best for intermittent use.

Uses a piston-cylinder setup to compress air.

Common in garages, workshops, and small businesses.

B. Rotary Screw Compressors

Designed for continuous-duty applications.

More efficient and quieter.

Preferred in industrial and commercial settings.

Choose reciprocating compressors for light to moderate work and rotary screw compressors for high-demand, continuous operations.

3. Assess Tank Size and Air Storage Capacity

Air compressors come with tanks that store compressed air. The larger the tank, the longer you can operate tools without the compressor motor restarting frequently.

Smaller tanks (1–10 gallons): Ideal for home use or quick jobs.

Medium tanks (20–60 gallons): Suitable for small workshops.

Large tanks (80+ gallons): Required for industrial use and extended air demand.

Important: The tank size doesn’t affect air pressure but does influence how long the compressor can supply air before recharging.

4. Consider Portability vs. Stationary Design

Depending on your work environment and mobility needs, you must choose between:

Portable Compressors

Lightweight, compact, and often have handles or wheels.

Great for job sites, home use, and mobile service units.

Stationary Compressors

Larger, fixed units designed for garages, factories, or workshops.

Pro Tip: Go oil-free if you need clean air and less maintenance. Choose oil-lubricated for high performance and longevity.

6. Analysed Duty Cycle and Workload Capacity

The duty cycle tells you how long a compressor can run within a 10-minute period without overheating.

50% Duty Cycle: Runs 5 minutes, rests 5 minutes.

100% Duty Cycle: Can run continuously without damage.

For industrial and continuous applications, choose a compressor with a higher duty cycle, preferably 100%. Occasional users can opt for lower-duty models.

7. Check for Power Source Compatibility

Air compressors are powered by either electricity or gasoline. Each type serves different environments.

Electric Air Compressors

Cleaner and quieter.

Require a stable power source.

Suitable for indoor or enclosed spaces.

Gas-Powered Compressors

Ideal for outdoor use and remote locations.

Produce emissions, so not suitable for indoor use.

Match your compressor’s voltage and amperage requirements with your available power supply. Larger units may require 230V or three-phase power.

8. Evaluate Noise Level (Decibels)

If noise is a concern—especially in indoor or residential areas—consider the compressor’s noise rating in decibels (dB).

Below 60 dB: Quiet models (good for indoor or medical use).

60–80 dB: Average for small to medium compressors.

Above 80 dB: Loud and better suited for industrial environments.

Look for models with built-in noise reduction or use soundproof enclosures for louder units.

9. Review Maintenance Needs and Spare Part Availability

Some compressors require regular oil changes, filter replacements, and belt checks. Consider how easy it is to perform maintenance and get replacement parts.

Choose a brand with strong after-sales support.

Look for readily available filters, valves, belts, and service kits.

Prefer models with user-friendly design for DIY maintenance.

10. Set a Realistic Budget with Long-Term Cost in Mind

While it’s tempting to go for the lowest price, consider the total cost of ownership, which includes:

Purchase price

Maintenance cost

Power consumption

Repair expenses

Expected lifespan

A slightly more expensive, energy-efficient and durable compressor can save more money over time than a cheaper, high-maintenance unit.

11. Consider Special Features and Add-Ons

Modern compressors offer added convenience and efficiency:

Auto drain valves: Automatically release moisture.

Thermal protection: Prevents overheating.

Dual quick-connects: For multiple tool usage.

Digital displays: Easy pressure monitoring.

Choose features that align with your needs and improve operational comfort.

12. Always Buy from a Trusted Manufacturer
