Abstract: A rotating crankcase ventilation filter element comprises a filter media comprising a plurality of filter media layers. A first endcap is positioned on a filter media first end of the filter media, and a second endcap positioned on a filter media second end of the filter media. the second endcap coupled to the first endcap such that the first endcap and the second endcap define an internal volume within which the filter media is disposed. The second endcap comprises an axial seal member extending from a surface of the second endcap towards the filter media and forming an axial seal with the filter media. The axial seal member projects substantially parallel to a direction of axial fluid flow entering the filter media.

Abstract: A crankcase ventilation device includes a housing and a flow directing member. The housing defines an inlet, an outlet and an internal volume. The inlet is configured to receive blow-by from an engine. The flow directing member is coupled to the housing and extends into the internal volume. The flow directing member includes a plurality of sidewalls, at least two of the plurality of sidewalls defining a window that fluidly couples the inlet to the internal volume. A filter media may be coupled to the flow directing member.
