Air Pump

Air pump is a belt-driven, positive displacement, vane type pump. It is available in 11 cu. in. and 19 cu. in. sizes. The 11 cu. in. pump takes air through a filter attached to air inlet nipple. The 19 cu. in. pump takes air through an impeller type centrifugal air filter fan, thus eliminating the need for a separate air filter.

Dust and dirt particles cannot enter the pump because these heavier-than-air particles are thrown from the air intake by centrifugal force. The air pump does not have a pressure relief valve, this function being controlled by the air by-pass valve.
