CP Genoil M is Chicago Pneumatics mineral-based compressor oil for rotary screw and reciprocating air compressors, supplied here in the 5.3 gallon size. High-quality mineral base oils carry a balanced additive package oxidation stability, rapid water separation, foam control and anti-wear protection for reliable lubrication in ambient temperatures from -10 C to +35 C, keeping industrial, construction and shop compressors running through standard operating conditions.
Seal and paint compatibility protects the machines internals, and de-aerating additives keep the oil film consistent under load. It is the service fill to keep on the shelf beside Chicago Pneumatic air compressors such as the CPS 185 KDU; a 1.32 gallon size of Genoil M is also available.
