Reasons for the blackening of the air compressor oil 1. The overall operating environment of the air compressor: The air compressor can easily react with nitrogen oxides and sulfides in a closed environment at a high temperature to generate alcohols, aldehydes, ketones, and acids. Oxygen-insoluble substances, and at the same time very easy to produce tiny hydrocarbon compounds and gases at high temperatures.

Second, due to the air compressor oil temperature is too high and a failure, the device is very easy to produce iron particles inhaled air particles.

How can we prevent air compressor oil from turning black?

First, seal the unused engine oil.

Second, when purchasing related products, choose special oil products that are not easily decomposed.

Third, keep the engine oil storage environment temperature and humidity in normal temperature operation....
