A filter assembly includes a ring of filter media, a first end cap, a second end cap, a first seal, and a second seal. The first end cap is coupled to a first end of the filter media. The second end cap is coupled to a second end of the filter media and includes (i) a radially extending portion having a first opening and (ii) a first axially extending portion having a stepped ledge defining a first inner diameter. The first seal is supported by the second end cap and includes a second opening defining a second inner diameter that is less than the first inner diameter. The second seal is supported by the second end cap and includes a third opening defining a third inner diameter that is greater than the first and second inner diameters. The stepped ledge is disposed between the first seal and the second seal.

Filter element

A filter is disclosed. The filter includes a sheet of filter media defining a body having an upper portion, a lower portion, a first end surface proximate the upper portion, a second end surface proximate the lower portion, and a first side surface extending between the first and second end surfaces. One or more of the upper and lower portions define a ledge, wherein the ledge defines a third end surface arranged between the first and second end surfaces, and a second side surface extending between the first and third end surfaces; and a seal disposed upon the ledge. A method for manufacturing the seal is also disclosed.

Filter

A filter element includes a first end cap, a second end cap, and a ring of filter media disposed between the first end cap and the second end cap. The ring of filter media circumscribes a central cavity. The filter element also includes an air-bleed conduit axially extending through the central cavity. The air-bleed conduit includes a first portion integrally formed with the first end cap and a second portion integrally formed with the second end cap. The second portion is configured to fluidly connect to the first portion.

Filter element with air-bleed conduit

A filter assembly includes a housing, a filter element, and an end cap. The housing includes an interior surface, an exterior surface, and a protrusion. The interior surface defines an interior volume. The exterior surface is opposite the interior surface. The protrusion extends from the exterior surface. The filter element is configured to be disposed at least partially in the interior volume of the housing. The end cap includes an axially-extending outer rim defining a slot configured to receive the protrusion to inhibit rotation of the end cap relative to the housing.

End cap for a filter element

A filter element includes a first end cap, a second end cap, and an intermediate end cap disposed between the first end cap and the second end cap. A ring of first filter media circumscribing a first central cavity is disposed between the first end cap and the intermediate end cap. A ring of second filter media is disposed between the intermediate end cap and the second end cap. The filter element also includes an air-bleed conduit axially extending through the first central cavity and comprising a first portion integrally formed with the first end cap and a second portion integrally formed with the intermediate end cap and configured to connect to the first portion thereby forming a conduit for transmitting fluid.

A sub-component of a replaceable filter element that is interfacably sealing a standpipe includes an end cap, said second end cap defining a first central opening; a central tube extending from the first central opening of the second end cap, wherein the central tube defines an inner surface, an outer surface and a top surface, wherein the top surface defines a second central opening, wherein the central tube includes an actuator excluding keys, free ends, or projections; and a standpipe seal disposed proximate the top surface of the central tube, wherein the standpipe seal defines a third central opening.

One aspect of the disclosure provides a filter element including a first end cap, a second end cap, a ring of filter media and an annular seal. The first end cap defines a cylindrical collar that circumscribes a first central opening and includes a substantially planar first outer surface that extends radially outward from the cylindrical collar to an outer peripheral edge. The second end cap defines a second central opening substantially coaxial with the first central opening. The ring of filter media is disposed between the first end cap and the second end cap, and circumscribes a central cavity in fluid communication with the first central opening and the second central opening. The annular seal is disposed upon the first outer surface of the first end cap and around the cylindrical collar. The annular seal extends axially way from the first outer surface.
