PowerQUAD™ 20/30/55 Gallon Liquid Shut-Off Assembly Model No PQ638

Perfect for wet vacuum tasks, the Liquid Shutoff Assembly ensures efficient fluid management by limiting the intake when the drum reaches capacity, protecting the exhaust silencer from damage. As the liquid level increases, the float ball rises and blocks the vacuum inlet, halting the vacuum operation. This wire cage with an internal float ball attaches to the drum cover’s underside, replacing the cartridge filter. Compatible with Guardair PowerQUAD™ 20, 30, and 55 Gallon Drum Vacuums and Vacuum Generating Heads.
