Synthetic, ester-based lubricating oil which offers excellent thermal and oxidation stability as well as protection against corrosion and wear at higher levels than conventional mineral oil. As result, it reduces wear on cylinders, rings and bearings, keeping air compressors cleaner with fewer deposits in the valves. These oils have been especially developed to meet the strictest specifications of reciprocating air compressor manufacturers, operating in extreme conditions with unloading temperatures up to 200ºC and start-up temperatures of -20ºC. Teh product is recomended for alternative type air compressors, used in marine, industrial and stationary applications.
