Valve Assembly - All units use large disc-type valves made from swedish steel for high efficiency and long durability.
After Cooler - The copper tube is fitted with high-efficiency cooling fins that effectively reduce gas working temperature and increase air compression efficiency.
Rings - Long life industrial design compression and oil control rings are used to assure maximum performance
Long-Life Cylinder - Precision-machined cylinder walls are honed glass-smooth to reduce friction and wear to a minimum. Extra-deep fins provide increased cooling and greater strength.
Continuous Running Unloader - For continuous-running air compressors. Unloader lets the unit idle load-free until air supply drops to cut-in pressure; automatically lets unit idle again after high pressure limit is reached. (Tubing and fittings are not included on bare pumps)
Balanced Fan-Type Flywheel - Airfoil-type spike provides a continuous powerful blast of cooling air for all parts of the compressor. Balanced flywheel provides smooth vibration less operation.
Cool Cylinder Head - Deep directional fins provide quick cooling. Compact streamlined air passages in the cylinder head permit fast, efficient flow of cooler intake and rapid removal of discharge air.
