Abstract:
A rotating crankcase ventilation filter element comprises a filter media comprising a plurality of filter media layers. A first end cap is positioned on a filter media first end. The first end cap comprises a first end cap main body, and a first plurality of indenting features positioned on the first end cap main body proximate the filter media first end. The first plurality of indenting features contact and indent corresponding segments of the filter media first end, causing the plurality of filter media layers to interlock at the corresponding segments. The interlocking prevents movement of the plurality of filter media layers relative to each other.
