Air Pump

Pump is belt driven from crankshaft pulley or from alternator. Pump takes air in 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 contaminants 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 bypass valve.
