What are the characteristics of air compressor lubricants

In addition to reducing the friction, wear and temperature rise of the motion pair, air compressor lubricants. It also has the function of sealing compressed air. The lubricating oil of the air compressor directly contacts the compressed gas of high temperature and high pressure, so it is easy to cause lubrication failures that are not found in other machinery.
