Oil-free air compressor compared to different places of oil-injected air compressor

From the oil content point of view, the oil and no oil in the air compressor generally refers to the amount of oil in the exhaust outlet of the air compressor. There is also a completely oil-free air compressor, which is not Oil lubrication is used, but water lubrication is used, so the final discharge of gas without oil is called water lubricated air compressor.

From the working principle, there are obvious differences between the two. Oil-free air compressor does not involve oil during operation. The high temperature generated during operation of water-lubricated oil-free screw machine is taken away by water. If oil is involved in air compressor, the high temperature generated during compression of air compressor will be taken away, thus cooling the machinery. However, the temperature difference between the two will be relatively large. The temperature of water-lubricated air compressor will not be higher than 70 degrees, and water will boil and stop above this temperature.

Oil-free air compressors are cleaner and more environmentally friendly than oil-free air compressors to some extent, so institutions such as hospitals, laboratories, schools and other institutions are very suitable for the use of oil-free air compressors.
