Campion Air Compressors - R Series Slash-Lubricated Pump

Loaded with rugged features, these splash-lubricated compressors deliver high performance, long life and tremendous value.
- Piston Rings
Three compression rings and one oil control ring provide excellent oil control, minimum blow-by and high efficiency air delivery.
- Integral Cylinder/Head
Gasketless design eliminates the possibility of blown head gaskets for trouble-free operation.
- Balanced Pistons
Aluminum alloy first-stage piston is weight-matched to the cast iron second-stage piston, ensuring proper balance.
- Multi-Finned Cylinders
Cooler operating temperatures result in longer life and consistent performance over time.
- Lightweight Connecting Rods
High-density, die-cast aluminum alloy rods, minimum 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.
- 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.
- Intercoolers
Large-diameter finned tubing is positioned to obtain the greatest cooling effect between stages
for maximum compressor efficiency.
- Pressure Relief Valves
Located in interstage and discharge.
- Loadless Starting
Positive acting, governor-type centrifugal unloader assures longer motor life by allowing
the compressor to start unloaded every time.
- Oversized Main Bearings
Tapered roller-type main bearings deliver the longest possible life.
- Balanced Crankshaft
Contructed 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.
