Large-diameter finned tubing is positioned to obtain the greatest cooling effect between stages for maximum compressor efficiency. An integral, precision- bored crank pin bearing and a needle bearing for the piston pin properly distribute bearing loads for longer bearing life than bushings. High-density, die-cast aluminum alloy rods minimize reciprocating weight. Two compression rings and one oil control ring provide excellent oil control, and high efficiency air delivery. Gasket-less design eliminates the possibility of blown head gaskets for trouble-free operation.Īluminum alloy first-stage piston is weight matched to the cast iron second-stage piston, ensuring proper balance.
Loaded with rugged features, the R-Series splash-lubricated compressors deliver high performance, long life and tremendous value.Ĭooler operating temperatures result in longer life and consistent performance over time.
