Mineral compressor lubricants with excellent resistance to rust and oxidation. . Their properties eliminate the risk of formation of deposits in valves and hot areas, consequently reducing equipment shutdowns and thereby maintenance costs. They also ensure great protection against wear in rings and liners. These lubricants are recommended for lubricating compressor cylinders and bearings, both rotary and reciprocating, for air or inert gases, with one or more stages, and operating in normal or severe conditions.
