Abstract
A filter element having an end cap is provided with a seal that can better accommodate non-round holes. The seal may be a chevron type seal and/or other similar seal having a sealing flange for forming a radial seal. Methods of replacing a filter having an O-ring gasket to improve upon sealing are provided as well as filtration systems employing the filter element.
Claims15
A filter element, comprising:
- a first end cap and a second end cap and a tubular ring of filter media extending between the end caps and around a longitudinal axis;
- a gasket carried by the first end cap, the gasket having an annular sealing flange and an annular base portion, the annular base portion carried by the first end cap with the annular sealing flange having an annular terminating end spaced either radially inside an inner peripheral surface or radially outside an outer peripheral surface of the first end cap, wherein the gasket is elastomeric with sufficient resiliency and flexibility to conform and seal to a non-round opening with up to at least 0.01 inch in a diameter variance from round,
- wherein the first end cap defines an annular groove, the annular base portion positioned in said annular groove,
- wherein the first end cap is an open end cap having an annular disc sealing a first end of the filter media, the annular disc having a central opening communicating with an internal cavity of the tubular ring of filter media,
- wherein the second end cap is a closed end cap having an annular disc sealing a second end of the filter media for creating radial flow through the tubular ring of filter media.

A filter element, comprising:
- a first end cap and a second end cap and a tubular ring of filter media extending between the end caps and around a longitudinal axis;
- a gasket carried by the first end cap, the gasket having an annular sealing flange and an annular base portion, the annular base portion carried by the first end cap with the annular sealing flange having an annular terminating end spaced either radially inside an inner peripheral surface or radially outside an outer peripheral surface of the first end cap, wherein the gasket is elastomeric with sufficient resiliency and flexibility to conform and seal to a non-round opening with up to at least 0.01 inch in a diameter variance from round wherein the first end cap is an open end cap having an annular disc portion surrounding a central flow opening, wherein the end cap defines an outwardly opening annular groove, the annular base of the gasket retained in the groove;
- wherein the second end cap is a closed end cap having an annular disc sealing a second end of the filter media, for creating radial flow through the tubular ring of filter media.

- a housing with an inlet and an outlet with flow from the inlet to the outlet and having a radial seal housing surface, wherein the housing comprises:
- a vessel having an inlet and an outlet,
- a partition wall having an array of flow openings and dividing the vessel into an inlet side and an outlet side;
- a plurality of sleeves mounted to the partition wall, each sleeve defining one of said radial seal housing surface, each sleeve aligned with one of the openings to facilitate flow therethrough, and wherein a plurality of filter elements are arranged in parallel circuit with each other, each filter element extending at least partly into one of the sleeves and radially sealed thereto.
