The difference between micro-oil and oil-free air compressor

What is the difference between micro oil air compressor and oil free air compressor?

At present, oil-free air compressors are improved and developed on the basis of oil-free air compressors. There are two main ways: one is to use water instead of oil, and the other is to coat the rotor with a self-lubricating coating.

Oil and no oil in the air compressor generally refers to the amount of oil content in the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the oil machine is relatively large, and the oil content of the oil-free oil machine is 0.01ppm. Therefore, this oil content is used to distinguish the oil and no oil in the air compressor. There is also a full oil-free air compressor, it is not the use of oil lubrication, but the use of water lubrication, so the final discharge of the gas does not contain oil called full oil-free air compressor.

Compressed air is the second largest power energy after electric power, and it is also a process gas source with multiple uses. Its application scope covers petroleum, chemical industry, metallurgy, electric power, machinery, light industry, textile, automobile manufacturing, electronics, food, Pharmaceutical, biochemical, scientific research and other industries and departments.
