ABSTRACT:
A liquid filter apparatus particularly useful in removing particulates from parts washing solvent. A filter assembly includes an exterior, fluid-impermeable container, preferably in the form of a flexible sidewall bag, and an interior filter element with permeable sidewalls and inlet and outlet ends, preferably in the form of a sleeve. In use, liquid entering the sleeve may pass unfiltered entirely through the sleeve and exit through a sidewall of the exterior container, or all or any part of such liquid may pass through the filter sleeve and into a portion of the apparatus outside the sleeve but inside the exterior container. From this portion, the liquid emerges in a filtered condition. Consequently, the filter continually operates in both filtration and bypass modes. Preferably the flexible sidewall container is received within a rigid support housing, two filter units are provided, and their inlets and outlets are removably secured to a manifold controlling passage of fluid to be cleaned from a liquid pump assembly and to another part of a parts washer associated with the filter.
