R-Series reciprocating compressors are loaded with features designed for day-in, day-out performance. This industrial air compressor delivers high performance and tremendous value. Available as a gas or diesel driven model, a maximum pressure of 175 psig can be reached with this reciprocating compressor. This product was designed to support single and two stage splash lubricated pumps. R-Series reciprocating compressors can be tank or base mounted, as a simplex or duplex model.
Positive acting, governor-type centrifugal unloader assures longer motor life by allowing the compressor to start unloaded every time.

Benefits at a glance…
Cooler operating temperatures result in longer life and consistent performance over time.
Gasketless design eliminates the possibility of blown head gaskets for leak-free operation.
Aluminum alloy first-stage piston is weight matched to the cast iron second-stage piston, ensuring proper balance.
Three compression rings and one oil control ring provide excellent oil control, minimum blow-by and high efficiency air delivery.
Lightweight Connection Rods
High-density, die-cast aluminum alloy rods minimize reciprocating weight. An integral, precision-bored crankpin bearing and a needle bearing for the piston pin properly distribute bearing loads for longer bearing life than bushings.
Pressure Relief Valves
Located in interstage and discharge.
Large-diameter finned tubing is positioned to obtain the greatest cooling effect between stages for maximum compressor efficiency.
Optimized Cooling Fan/Flywheel
Precision balanced flywheel has fan blades for optimum compressor cooling and life.
Reliable, High-Flow Valves
Single-unit, disc-type valves provide low lift and long life. Discs are made of corrosion resistant Swedish steel. Valves are easily serviced by removing the manifolds only.
Oversized Main Bearings
Tapered roller-type main bearings provide full contact and support of the crank plus delivers the longest possible life.
Constructed of rugged ductile iron with large diameter throws for minimum bearing loads and counterweights to minimize vibration.
Large Capacity Crankcase
Rugged cast iron oil reservoir has convenient sight gauge glass, corner oil fill boss and large oil drain.
