Powered by compressed air, this wet-only pick-up vacuum creates waterlift substantially beyond that found in traditional wet vacuums. This unit was designed for wet recovery applications requiring extremely aggressive pick-up power. The only other wet-only pick up vacuum we have in our jumbo industrial vacuums section, is our air powered oil recovery vacuum. From the assembly line to the tool shop, these units handle such challenges as heavy oil, machine oil, ink, sludge, and a variety of other common type of liquid debris in an industrial environment.
