Compressor oil is composed of a mixture of high quality lubricating base fluids and high-performance additives that offers exceptional lubrication in compressors in various types of service. Compressor oil is designed to lubricate and seal the compression components as well as lubricate the bearings inside the compressor. In addition, the fluid helps to reduce the buildup of carbonaceous deposits in the compressor valves and downstream piping, thus increasing the compressor life. Compressor fluids are typically rust and oxidation inhibited antiwear products blended to standard ISO viscosity grades. They are often customized for the intended service (air, gas, or refrigeration) as well as the type of compressor to be lubricated (rotary screw, reciprocating, axial, etc.).
