Types of Oil-Free Air Compressor

The oil-free air compressors produced by our company mainly include the following types

Oilless Screw Compressor

The 150 CFM Air Compressor features a stainless steel gas seal that provides excellent corrosion resistance and sealing performance, effectively preventing gas leakage and ensuring the quality and pressure stability of compressed air. Additionally, the unique labyrinth oil seal design further enhances the sealing effect, preventing lubricating oil leakage, reducing compressed air pollution, and protecting internal components from impurities.

Oil-Free Rotary Screw Air Compressor

The Oil-Free Rotary Screw Air Compressor is an essential tool for equipment maintenance and testing in demanding industries such as oil refineries, nuclear power plants, and the petroleum, petrochemical, and natural gas sectors. In these high-stakes environments, ensuring the purity and reliability of compressed air is critical.

Oil Free High Pressure Air Compressor

The larger 700 CFM model provides a higher air volume, making it suitable for heavy-duty applications such as large-scale construction or oil refinery operations, where consistent and high-capacity air delivery is crucial. However, both models maintain similar high standards for environmental protection and ease of maintenance, ensuring sustainable and reliable operations across a variety of industries.

‌Precautions For Using Oil-free Air Compressors

● Grounding protection‌: When using an oil-free air compressor, a compressor protection grounding wire must be installed to ensure that all metal shells of the compressor are in good contact with the ground, and the grounding resistance should meet national standards‌.

● ‌Clean environment‌: Keep the workplace clean and tidy, avoid clutter and disorder, to reduce the possibility of accidents‌.

● ‌Environmental requirements‌: Oil-free air compressors should be protected from wind and rain, do not work in humid air or dark places, and do not store flammable and explosive liquids and places with excessive dust‌.

● ‌Regular maintenance‌: Regularly check and maintain the air compressor, at least once a quarter, including removing dust and dirt, checking connecting bolts, electrical circuits, etc. ‌ ‌Filter cleaning‌: The filter medium in the filter should be cleaned every three months, and if necessary, it should be washed with water and dried before use‌.

● ‌Safe operation‌: If serious air leakage, abnormal sound or odor is found, stop the operation immediately, find out the cause and eliminate the fault before operating again‌.

● ‌Power supply voltage‌: Make sure the power supply voltage is consistent with the voltage and current marked on the oil-free air compressor to avoid damage to the equipment due to over-high or under-low voltage‌.

Comparing the Key Differences Between Oil and Oil-Free Air Compressors

Lubrication requirements
As its name suggests, an oil air compressor requires oil to lubricate its moving parts. For example, if you have a rotary screw air compressor with lubricated helical screw pairings, you must change the oil and oil filters to ensure it operates properly. In comparison, oil-free air compressors use a different lubrication medium to operate, eliminating the need for oil.

Maintenance needs
It likely goes without saying that oil-flooded air compressors require more maintenance. If users neglect to change the oil or check the oil filters or provide routine maintenance, their air compressors will not be as reliable and might not live a long, trouble-free life. Comparatively, oil-free air compressors come with fewer maintenance needs, but they tend to not last as long as a properly maintained lubricated system. Once the frictionless coating starts wearing off in oil-free compressors, you will need to replace your compressor in short order. They also run hotter than lubricated systems.

Maintenance costs
Because oiled air compressors use oil, they are more expensive to operate. To properly maintain your air compressor, you must have oil on hand so you can change out the old oil based on the manufacturer’s maintenance schedule. However, oil air compressors tend to last longer than oil-free air compressors, which can offset the costs required to operate them.

Contamination risks
If your company is not concerned with oil contamination, an oiled air compressor can be a highly effective and reliable tool for your operations. For businesses where any contamination must be avoided, the oil-free alternative is the best option.

Noise levels
An oil-lubricated air compressor is quieter because it has the oil to lubricate it. If you are OK with using oil in your applications and would prefer to use a machine with less noise in your work area, choose an oil air compressor. Though they still produce more noise, the good news is modern oil-free air compressors are quieter than previous models.

Mobility
Oil-free air compressors are lighter in weight than oil-lubricated systems. Part of this is because they don’t require additional oil water separators, gallons of oil, oil filters, and other equipment that oil-flooded systems require.

Our Factory

Jiangxi Gas Compressor Factory began as Ganzhou Machinery Factory after the public-private partnership in 1951. It was renamed Ganzhou Machinery Factory in 1955, Gannan General Machinery Factory in 1958, and Jiangxi Gas Compressor Factory in 1969. Jiangxi Gas Compressor Factory was always at the forefront of the industry in terms of technical strength in the 1970s and 1980s. As a result, the First Ministry of Machinery Industry at that time designated Jiangxi Gas Compressor Factory to conduct research and production of many new models.

FAQ

Q: Can an oil-free air compressor run continuously?

A: An oilless air compressor is unsuitable for applications requiring high pressures or continuous operation. They are best suited for intermittent use in the medical, food, or electronics industries.

Q: Are oil-free air compressors any good?

A: While the performance differences between these compressors were more pronounced in the past, today, each is designed to do its respective job well. In general, for sensitive air jobs, go with oilless. If the quality of the air doesn't matter, go with either.

Q: How long will an oilless air compressor last?

A: These compressors usually have a shorter lifespan than oil-flooded rotary screw compressors, typically lasting up to 70,000 hours or 10-15 years.

Q: How do you maintain an oil free air compressor?

A: Keep the pressure in control. Having the right pressure levels is important so that the oil-free air compressor can work with maximum efficiency and productivity.
Ensure your power lead is functional.
Keep an eye on the leaks.
Evaluate the air filter regulatory.

Q: How do you break in an oilless air compressor?

A: Set the pressure switch OFF/AUTO lever to the "OFF" position.
Plug the power cord into the correct branch circuit receptable.
Turn the regulator clockwise, opening it full, to prevent air pressure build-up in the tank.
Move the OFF/AUTO level to "AUTO".
Run the compressor for 15 minutes.

Q: Can I leave air in my compressor overnight?

A: Even if your air compressor's pump cycles only a handful of times per day, you should drain your compressor tank every other day or several times per week to prolong its operating life and to protect your pneumatic devices and equipment.
