Liquid Shut-Off Assembly – 20/30/55 Gallon Vacuums – Model No. N638
Ideal for wet vacuum applications, Liquid Shutoff Assembly limits the intake of vacuumed fluids when the drum is full, preventing damage to exhaust silencer(s). Float ball rises as liquid level rises, blocking vacuum inlet to Venturi box, ceasing vacuum operation. A wire cage with internal float ball mounts to drum cover. Replaces standard (dry) cartridge filter. Available as a stand-alone item or factory-installed option.
