Reversible vacuum pump out operation. The Spillrite two way reversible vacuum and pump out system utilises a unique venturi that has a double reverse way action. When the system is in reverse mode the internal reverse venturis direct the compressed air into the drum forcing the fluid up the internal drop pipe and out through the suction/pump out hose. The internal pressure cannot build up above 9 psi as only one venturi is blocked and one is left open to allow escape of pressure.
Pressure is also released through the suction/pump out hose.
