    Abstract: 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.

    Abstract: 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.

    IPC: B01D29/15

    Abstract: 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.

    Abstract: 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.
