American Made

• 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.
