ABSTRACT:
A parts washing apparatus comprising a basin having a drain, a reservoir located below the drain, and a solvent filtering and recirculating system. This system comprises a centrifuge filter assembly and a solvent recirculating system. The centrifuge filter assembly in turn comprises a centrifugal filter comprising a receptacle and a replaceable filter element, and also a turbine to drive the centrifugal filter. The centrifuge filter and the turbine are positioned in an enclosing structure to enclose the turbulent flow of the solvent from the centrifuge filter and also enclose the fumes associated with the turbulent flow. Thus, there is a discharge of solvent as less turbulent flow while substantially enclosing the associated fumes.
