Technical Information

N/A Long lasting cast iron, hard chrome plated cylinders. PTFE guide rings prevent the pistons from contact, raising efficiency. Sealed anti-friction bearings in the upper and lower connecting rod ends for increased life.

Strong ductile iron crankshafts are mounted with sealed anti-friction bearings in a rugged cast iron crankcase.

Cast iron heads and spring-loaded valves with stainless steel cages, phosphoric bronze seats and Swedish steel discs keep your compressor running cool and offer a longer operating life.

Large aluminum cooling fan and low compressor speeds keep the PureAir II crankcase, cylinders and heads running cool, reducing wear and increasing the life of the unit.
