Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.
