What Is Air Compressor Oil?

The lubrication principle of air compressor oil is to reduce friction. The so-called friction means that when two relative moving surfaces undergo relative displacement under the action of external force, there is an opposite contact surface, called a friction surface. There are many types of friction phenomena, including external friction, internal friction, sliding friction, rolling friction, dry friction, boundary lubrication friction, fluid lubrication friction and mixed lubrication friction.
