CHAMPION R SERIES

Model: R70A TWO-STAGE BARE PUMP (20, 25, 30 HP)

Multi-finned cylinders- Cooler operating temperatures result in longer life and consistent performance over time.

Integral cylinder/head- Gasket-less 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.

Piston rings- Two compression rings and one oil control ring provide excellent oil control, and high efficiency air delivery.

Lightweight connecting rods- High-density, die-cast aluminum alloy rods minimize reciprocating weight. 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.

Pressure relief valves- Located in interstage and discharge.

Intercoolers- 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.

10 Over-sized main bearings- Tapered roller-type main bearings provide full contact and support of the crankshaft plus delivers the longest possible life.

11 Balanced crankshaft- Constructed of rugged ductile iron with large diameter throws for minimum bearing loads and counterweights to minimize vibration.

12 Large capacity crankcase- Rugged cast iron oil reservoir has convenient sight gauge glass, corner oil fill boss and large oil drain.

13 Loadless starting- Positive acting, governor-type centrifugal unloader assures longer motor life by allowing the compressor to start unloaded every time.
