Abstract
A filter element includes a first filter media defining a central channel. An endcap is disposed on an end of the filter media, the endcap defining an outlet for clean fluid to exit the filter media. A second filter media is disposed radially inward of the first filter media, the second filter media structured to coalesce water. A hydrophobic screen is disposed across the outlet defined in the endcap.
Claims22
A filter element, comprising:
- a first filter media defining a central channel;
- an endcap disposed on an end of the first filter media, the endcap defining an outlet for clean fluid to exit the filter element, and the endcap comprising an endcap flange;
- a sealing member disposed within the outlet such that a radially inner surface of the endcap flange contacts a radially outer surface of the sealing member to form a radial seal therebetween;
- a second filter media disposed radially inward of the first filter media, the second filter media structured to coalesce water;
- and
- a hydrophobic screen disposed on the sealing member across the outlet defined in the endcap.

A sealing member for forming a seal between a filter element and a filter head, comprising:
- a sealing member main body configured to be disposed within a central channel of a filter media of the filter element, the sealing member main body defining an upstream end of the sealing member;
- a sealing member downstream portion located downstream of the sealing member main body, the sealing member downstream portion having a larger cross-sectional width than the upstream end, wherein the sealing member further comprises a plurality of arms extending radially outwards from an outer surface of the sealing member downstream portion;
- a sealing member intermediate portion coupling the sealing member main body to the sealing member downstream portion;
- and
- an endcap sealing portion comprising a circumferential wall extending axially towards the upstream end of the sealing member from the sealing member intermediate portion such that a radial space is formed between the sealing member main body and the endcap sealing portion.

A filter element comprising:
- a filter element comprising a filter media having a central channel;
- a sealing member comprising:
- a sealing member main body disposed within the central channel of the filter media of the filter element, the sealing member main body defining an upstream end of the sealing member;
- a sealing member downstream portion located downstream of the sealing member main body, the sealing member downstream portion having a larger cross-sectional width than the upstream end;
- a sealing member intermediate portion coupling the sealing member main body to the sealing member downstream portion;
- and
- an endcap sealing portion comprising a circumferential wall extending axially towards the upstream end of the sealing member from the sealing member intermediate portion such that a radial space is formed between the sealing member main body and the endcap sealing portion and
- an endcap comprising an endcap outlet and an endcap flange extending axially from an inner peripheral edge of the endcap outlet into the central channel of the filter media;
- and
- wherein the endcap sealing portion is disposed with the central channel of the filter media such that a radially inner surface of the endcap flange is disposed around and contacts a radially outer surface of the endcap sealing portion to form a radial seal therebetween when the sealing member is coupled to the endcap.
7 more elements
A filter element, comprising:
- a first filter media defining a central channel;
- a filter media tube disposed within the central channel, the filter media tube having a tapered profile along a longitudinal axis of the filter element;
- and
- first and second end caps disposed on first and second ends of the first filter media, wherein the filter media tube extends between and is connected to the first and second end caps, the first endcap defining an outlet for clean fluid to exit the filter element.
