Lubricated rotary screw air compressors mix oil with the intake air to lubricate the compressor's screws. After the air is compressed an air/oil separator separates compressed air from compressor oil. The compressor lubricant collects at the bottom of the separator tank and the compressed air continues to the air receiver. A standard rotary screw separator reduces the lubricant entrained in the compressed air to 2-3 ppm. Under normal operating conditions an oil separator's service life is 4,000 to 6,000 operating hours.

Purification of air we breathe carries contaminants. Airborne particles, water, microbes, and chemical gases enter compressors. At a state these contaminants become concentrated and more destructive.
