FSafety Relief Valve
Bleed-type Master Air Valve (B)
Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts.
The bleed-type master air valve is required in your system to relieve air trapped between it and the air motor when the valve is closed.
Air Regulator (C)
Adjusts air pressure to the motor and fluid outlet pressure of pump. View the gauge (D) to read air pressure.
Air Filter (E)
Removes harmful contaminants from entering the air control module and air motor.
Safety Relief Valve (F)
Automatically opens to relieve air pressure, to prevent pump overpressurization.
