Abstract: A filter element may include a tubular element defining an internal space, and a retainer element associated with a first end of the tubular element, wherein the retainer element is configured to be coupled to a first housing. The filter element may also include a valve seat member in the internal space. The valve seat member may include a valve seat aperture configured to provide a fluid seal with a valve poppet. The filter element may further include first and second end caps associated with ends of the tubular element. The filter element may also include filter media around the tubular element, and the second end cap may be configured to provide a fluid seal between the filter element and a drain passage in a second housing, such that as the filter element is separated from the second housing, fluid flows from the filter element into the drain passage.

Abstract: A filter element for an air cleaner assembly may include a first side member and a second side member opposite the first side member. The first and second side members may extend in a substantially longitudinal direction and substantially within respective first and second planes with an intermediate space therebetween. The filter element may further include filter media separating and extending between the first side member and the second side member in the intermediate space. The first and second side members and the filter media may have a perimeter cross-section substantially perpendicular to the longitudinal direction, and the filter element may further include a locating flange extending substantially around the perimeter cross-section and transverse to the longitudinal direction, wherein the locating flange does not lie within a single plane.
