Multi-finned Cylinders Cooler 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 Three compression rings and one oil control ring provide excellent oil control, minimum blow-by 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 fly wheel 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. Over-sized Main Bearings Tapered roller-type main bearings deliver 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. Load-less Starting Positive acting, governor-type centrifugal unloader assures longer motor life by allowing the compressor to start unloaded every time.
