What is the difference between an oil-free air compressor and an oil air compressor?

From the perspective of oil content, the oil and oil in the air compressor generally refers to the oil content of the exhaust gas from the air compressor exhaust port. Generally, the oil content of the oil machine is large, and the oil content of the oil-free machine is 0.01ppm, so use this oil content to distinguish between air compressors with oil and no oil. There is also a completely oil-free air compressor, which is not lubricated with oil, but is lubricated with a resin material, so the final gas discharged without oil is called a full oil-free air compressor.

From a structural point of view, there is no difference between an oil-free air compressor and a bearing with an oil air compressor. However, from the working principle, there are obvious differences between the two. Oil-free air compressors are not involved in the operation of the oil, whether it is oil-free piston machine or oil-free screw machine, they will generate a lot of high temperature during the operation, if there is oil air compressor oil Participation will take away the high temperatures generated during the compression of the air compressor, thus cooling the machine.

However, oil-free air compressors do not involve oil, and a large amount of high temperature is generated during the compression process. How to solve the high temperature to ensure the normal operation of the machine? In fact, the oil-free air compressor uses a type called Teflon or two. The special high-temperature resistant material of molybdenum sulfide replaces the oil to solve the high temperature in the compression process of the air compressor, thus achieving the purpose of oil-free compression.

Oil-free air compressors are somewhat cleaner and more environmentally friendly than oil-based air compressors. Therefore, hospitals, laboratories, schools and other institutions are very suitable for the use of oil-free air compressors. These institutions also prefer to use no air compressors.
