Abstract: The technology disclosed herein relates to a filter element having a first endcap, a second endcap, and filter media extending between the first endcap and the second endcap. The filter media defines a central opening and is coupled to the first endcap and the second endcap. A filter cover is coupled to the first endcap, and a breather filter is integral to the filter cover. The breather filter defines a first flow face and a second flow face. The filter element defines an airflow pathway from ambient environment through the first flow face and the second flow face.

Abstract: A removable filter assembly for filtering a fluid having a particulate or a contaminant and configured to engage a filter housing having a center post. The removable filter assembly includes a filter element adapted to remove at least one of the particulate or contaminate from the fluid, wherein the filter element includes an interior wall defining a passage having a first end and a second end. A container arrangement includes a channel and an outer wall in contact with the filter element at the first end of the passage, wherein the outer wall defines an outer profile extending from the first end of the passage toward the second end of the passage. The channel defines an inner wall configured to provide a relatively fluid tight seal with the center post. The container arrangement is adapted to capture at least one of the particulate or contaminate from the fluid. The outer wall of the container arrangement can include a plurality of radially aligned ribs.

Abstract: A filter element has a filter media assembly extending between a first end and a second end to define a media length along a longitudinal axis. The filter media assembly defines a central opening on an upstream side and an outer radial boundary on a downstream side. A first endcap is coupled to the first end. The first endcap has a media potting structure defining an annular surface abutting the first end of the filter media assembly, an inner tubular flange extending longitudinally from the annular surface into the central opening, and an outer tubular flange extending longitudinally from the annular surface over the outer radial boundary of the first end of the filter media assembly. The first endcap has an outer circumferential sealing surface about the longitudinal axis and a shroud to obstruct fluid flow extending longitudinally from the outer circumferential sealing surface towards the second end.
