How to lubricate an oil-free air compressor

air compressors can be divided into two types according to different lubrication methods. One is oil-free air compressors and the other is oil-free air compressors. The latter uses lubricating oil to lubricate the parts to reduce the wear between the parts. The oil-free air compressor is not involved in the operation of the lubricating oil. Therefore, the compressed air is not polluted by the lubricating oil. Speaking of this, there are customer questions, oil-free air compressor does not need lubrication? Here to answer everyone's questions.

Oil-free screw air compressor adopts advanced oil-free water lubrication single screw compressor technology, compared with dry double screw, air compressor parts are completely free of lubricating oil, ensure oil-free compression, provide reliable oil-free compressed air solutions.

Oil-free air compressor mainly uses water to replace oil, realizing the four major effects of lubrication, cooling, sealing and noise reduction, providing high-quality oil-free air, no pollution, and no special treatment for discharged water, which meets the requirements of environmental protection. Due to the role of water, its compression is an ideal isothermal compression. The gaps of various mechanical parts forming the compression chamber use the water film effect to prevent air leakage. The amount of air discharged is 25% more than that of a dry screw compression.

It should be noted that the compressed air of the oil-free air compressor is not 100% oil-free. Because the air contains a small amount of oil, the compressed gas also needs to be treated.
