A liquid filter, with a housing inlet port and outlet port arranged at the bottom of the liquid filter. The liquid filter may also be configured with an inward projecting domed top cover and/or an eccentric septum plate supporting a desired filter element and/or filter basket. The inward projecting domed top cover configurable with respect to the septum plate to retain the desired filter element and/or filter basket in place when in a closed position.

Bottom feed liquid filter

A fluid filtering device includes a housing having an interior chamber with an open top and an inlet and outlet open to the chamber. An annular seat is secured to the housing within the chamber in a position spaced downwardly from the open top so that the seat protrudes inwardly into the chamber. A filter element is removably insertable into the chamber through its open top and to a filtering postion in which the filter element is positioned between the housing inlet and outlet. The filter element includes an outwardly flanged portion which abuts against the seat when the filter element is in its filtering position. A cover is detachably secured over the open top of a housing and a spring member is secured at one end to the filter element to extend upwardly to abut against the cover and secure the filter element in position against any loss of seal with respect to the housing during operation of the filtering device. A handle is mounted to the filter element to facilitate removal and insertion of the filter element.

Fluid filter retaining device

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.
