What oil does the air pump and air compressor use?

What oil to add to the air compressor depends on different situations:

1. 100 to 150 air compressor oils are used for piston air compressors.

2. No.68 to 100 compressor oil for vane air compressor.

3.32 to 46 screw oil.

The function of oil in air compressor is to form a protective film between two friction pairs to avoid direct contact between metals, thus buffering friction, lubricating, reducing wear and protecting the normal operation of machinery. This protective film can be physical adsorption film, chemical adsorption film or oxide film, and the thickness and strength of the film directly affect lubrication. Simply put, air compressor oil mainly plays the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Million car purchase subsidy
