AirlFluid Regulator Kit

The AirlFiuid Regulator Kit is an assembled unit. It consists of the following parts:

one air regulator (B) to control the air pressure to the pump (A), and a second regulator trol the air pressure to the spray gun (H)

an air line fitting nect the main air line to the airlfluid regulator kit

connectors and fittings.

Connect the pump air regulator (B) to the pump's air inlet. Use this regulator to control pump speed and

fluid pressure.

The regulator kit's air inlet consists of a quick-disconnect coupler (503) and a pin fitting (502). Disconnect the coupler from the pin fitting and screw it onto the end of your air supply hose, but do not reconnect the coupler to the pin fitting yet.

System Accessories Install an air line filter remove harmful dirt and moisture from the compressed air supplied to the pump and gun. Downstream from the pump air regulator (B), install a bleed-type master air valve adapters.
