ABSTRACT:
A vacuum cleaner treats cleaning air by forcing the air through a liquid bath so as to remove suspended particulates within the air. The cleaner comprises a pan member adapted to contain the fluid bath, a cleaning air inlet, an upper casing supported from and secured to the pan member, and a motor mounted on the upper casing having a cooling air inlet and cooling air exhaust separate from that of the cleaning air. A main baffle shrouds the cleaning air inlet for the containment of the over splash created by induced fluid turbulence created in the liquid bath by the incoming cleaning air. At least two fluid collector rings are mounted between the cleaning air inlet and cleaning air outlet to provide a circuitous path for the cleaning air after it has traveled through the fluid bath to collect liquid particles and moisture in the cleaning air and redirect it back into the liquid bath. A replaceable air filter is located above the fluid collector ring, through which the cleaning air must pass before exiting through the cleaning air outlet and into the environment to remove additional particulate matter.
