What Are The Advantages Of Oil-Free Air Compressors In Use?

Firstly, the machine itself is made of materials that are free from oily substances. During operation, there is no need to add any lubricating oil. This significantly enhances the quality of the discharged air and ensures the safety of the user's associated equipment. In contrast to oil-lubricated air compressors, which emit gases containing a large amount of oil molecules that can cause varying degrees of corrosion to the user's associated equipment, choosing an oil-free, silent air compressor is essential for ensuring air quality.

Secondly, the maintenance of oil-free, silent air compressors is more convenient and straightforward compared to oil-lubricated compressors. As is well known, some oil-lubricated compressors require regular oil changes, and some may experience oil spraying or leakage, causing pollution to the surrounding environment. This necessitates users to spend time on cleaning, which increases the workload, contradicting people's desire to use machinery and equipment to improve work efficiency.

In comparison, oil-free, silent air compressors basically require no user maintenance time since they don't use a drop of oil. The fully automatic pressure sensing switch starts or stops the compressor based on the user's air consumption, making it both hassle-free and energy-efficient. The automated drainage device also adds to user convenience, making it extremely user-friendly. Moreover, the lifespan of oil-free, silent air compressors is longer than that of oil-lubricated silent compressors!

Through surveys, users who have used silent oil-free air compressors have expressed their willingness to recommend such compressors to friends!

With the rapid development of industry and the improvement of people's living standards, there is a significant increase in society's demand for required products. Simultaneously, the increased precision of pneumatic components has led to higher requirements for compressed air, demanding that it be free from oil and water. In the past, the extensive use of new oil-free air compressors was greatly restricted due to quality issues. However, with the improvement in the quality of oil-free air compressors, their fundamental improvement has fully met the needs of modern industrial production. The superiorities of oil-free air compressors during use are reflected as follows:

1.Due to the high viscosity of lubricating oil, oil removal equipment cannot completely remove it. Therefore, the characteristic of oil-free compressed air produced by oil-free air compressors becomes irreplaceable.

2.Oil-removal equipment such as refrigerated dryers, heatless regenerative dryers, and micro-heat regenerative dryers lose their dew point reduction function due to the presence of oil in compressed air. In contrast, the clean, oil-free gas compressed by oil-free compressors fully protects dew point reduction equipment, reducing additional funds required for maintaining dew point reduction equipment.

3.Using oil-free air compressors to supply compressed gases externally does not incur pressure loss due to oil removal equipment, significantly reducing the motor load and achieving energy-saving effects. High-quality three-stage oil removal devices generate 1 to 1.2 kilograms of pressure loss during use. For example, a 7.5KW air compressor will expend an additional 600W of power consumption for every 1 kg increase in pressure. Over a day's work (taking 10 hours as an example), this translates to 6 degrees of electricity consumption, representing a long-term invisible expense.

4.Using oil-lubricated air compressors significantly wastes lubricating oil. For a 7.5KW high-quality oil-lubricated air compressor, the minimum monthly consumption is 5 kilograms of lubricating oil. Over a year, this results in an additional cost of 60 kilograms of lubricating oil. Additionally, to remove oil from compressed gases, efficient oil filters must be used, requiring multiple replacements of filter cores, which is also a considerable expense.
