ABSTRACT:
A filter and replaceable filter leaf apparatus are provided. The filter includes a housing defining a cavity having fluid inlet and outlet ports and a lid member with a manifold coupled to the outlet port and being adapted to conduct a fluid flow between the outlet port and a plurality of attachment areas. Replaceable filter leafs are selectively movable through an opening into the housing cavity and attachable with the manifold at the plurality of attachment areas. The replaceable filter leafs include a filter envelope consisting of a single substantially rectangular filter panel, a nozzle member on the filter panel and defining a passageway adjacent an opening in the filter envelope for conducting fluids therethrough, and a porous grid member contained within the filter envelope. The nozzle member is selectively attachable onto the manifold of the polishing filter apparatus at one of the plurality of attachment areas. In one form, the filter envelope includes a folded rectangular filter panel with the nozzle member disposed at an outer edge thereof. In another embodiment, the nozzle member is located at a crease line formed in the filter panel. In yet another, a pair of filter panels are connected at their edges with the nozzle member located along a selected edge as desired. The filter leaf apparatus are installed onto the manifold along attachment axes extending through the housing opening.
