The formation and harm of carbon deposits in air compressor

The reasons for the formation of carbon deposits in air compressors are more complicated. In terms of air compressor oil lubrication, the main reason is that the oil used in the internal lubrication system of the air compressor is often in the form of mist and high temperature, high pressure, high oxygen partial pressure air and metal The contact of the catalyst causes the air compressor oil to rapidly oxidize and deteriorate.
