r-series 5 hp air compressor two stage 80 gallon 208/230v 1-phase | vr7f-8
loaded with rugged features, the champion r-series splash-lubricated compressors deliver high performance, long life and tremendous value.
1 multi-finned cylinders - cooler operating temperatures result in longer life and consistent performance over time.
2 integral cylinder/head - gasketless design eliminates the possibility of blown head gaskets for trouble-free operation.
3 balanced pistons - aluminum alloy first-stage piston is weightmatched to the cast iron second-stage piston, ensuring proper balance.
4 piston rings - two compression rings and one oil control ring provide excellent oil control, and high efficiency air delivery.
5 lightweight connecting 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.
6 pressure relief valves- located in interstage and discharge.
7 intercoolers - large-diameter finned tubing is positioned to obtain the greatest cooling effect between stages for maximum compressor efficiency.
8 optimized cooling fan/flywheel - precision balanced flywheel has fan blades for optimum compressor cooling and life.
9 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 oversized 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.
