Vanguard Reciprocating Compressor Oil is a premium synthetic lubricant formulated for reciprocating air compressors working in difficult applications. Premium synthetic base stocks and performance additives hold viscosity across wide temperature swings ISO 68 grade, about 68 cSt at 40 C with a viscosity index near 139 while a 270 C (518 F) flash point and a pour point of 51 C (59.8 F) cover hot-running compressors and cold-weather starts alike.
Vanair calls for this oil across all of its reciprocating air compressors, including the 20 CFM piston compressor on the Air N Arc 150 all-in-one power system, and its excellent demulsibility sheds the condensed water that compressor duty cycles pull in. Crowder Supply stocks quarts and gallons in Denver next to the Vanair compressors they serve, alongside our wider ranges of compressor and tool oils and air compressor accessories.
