The working principle of an oil-free air compressor

The essence of oil and oil-free air compressors is to provide users with compressed air, but in terms of working principle, there are obvious differences between the two. Because the air compressor will generate a lot of high temperature during the compression process, the oily air compressor will take away the high temperature generated during the compression process of the air compressor because of the participation of lubricating oil, thereby cooling the machine.

Oil-free air compressors do not have lubricating oil during operation. Therefore, oil-free air compressors must find a solution to high temperature. Traditional oil-free piston and oil-free screw air compressors mostly use Teflon or molybdenum disulfide special resistance. High-temperature materials can solve the problem of high temperature in the work of air compressors, but they still need to use lubricating oil for lubrication between bearings, cranks, and sliders. The oil evaporates, which ultimately affects the cleanliness of the compressed air and cannot do to be completely oil-free.
