CVP Central Liquid Ring Vacuum Systems

AF™ Series CVP Central Vacuum Systems provide a remote supply of plant vacuum which can be located away from the production area or vacuum outlets, reducing noise and heat in the work area. CVP systems feature the “A” Series single-stage liquid ring pumps in either a simplex or duplex design. 

These energy-efficient systems are designed to operate automatically, with the pump(s) starting when the plant vacuum demand increases and stopping when the demand is met.
