Champion VR7F-8 Air Compressor with Aftercooler, Starter Auto Tank Drain, Low Oil Monitor, and Vibration Pad - 230V, 1PH, 7.5HP, 80GL
The Champion Advantage Series offers a complete line of compressed air packages that meet any application. The Advantage Series has been carefully engineered to stand up to years of use.
Multi-finned cylinders- Cooler operating temperatures result in longer life and consistent performance over time.
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 secondstage 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 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.
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.
Oversized main bearings- Tapered roller-type main bearings provide full contact and support of the crankshaft plus delivers the longest possible life.
Balanced crankshaft- 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.
Loadless starting- Positive acting, governor-type centrifugal unloader assures longer motor life by allowing the compressor to start unloaded every time.
