ABSTRACT:
A fluid filter includes a housing having a fluid inlet, a fluid outlet, and an open top filter chamber intermediate the inlet and the outlet. The filter chamber is adapted to receive a filter basket holding a filter bag therein. The filter basket is supported in the filter chamber by the bottom end of the basket which engages an inwardly radiused wall portion of the housing. The basket includes a support plate for supporting the bottom of the filter bag within the basket above the bottom end portion of the basket. The lower end of the basket beneath the plate includes a wall portion which can be modified to conform to the shape of the housing to stably support the filter basket in a fixed position within the filter chamber. The filter bag includes a seal ring adapted to seal against the periphral wall of the filter chamber so that fluid entering the filter through the inlet is forced to pass through the filter element before it reaches the outlet, and the seal member is supported by the top lip of the filter basket.
