Abstract: Filter media and media packs that provide robust performance in high-speed rotating coalescer (HSRC) elements for crankcase ventilation systems are described. The filter media is HSRC filter media. As such, the filter media has a higher resistance to compressibility than traditional coalescer filter media, such as filter media used in low-speed rotating coalescer arrangements or stationary coalescer arrangements.

Abstract: A filter assembly for separating liquid from a fluid mixture that includes a filter housing with an inner surface, a filter element configured to separate a liquid from a fluid mixture and defining an outer surface, and a porous filter media. The filter element is positioned within the filter housing such that the outer surface of the filter element faces the inner surface of the filter housing. The porous filter media is attached to the inner surface of the filter housing to facilitate drainage of the liquid through the filter housing and prevent liquid carryover after the fluid mixture flows through the filter element.

Abstract: Filter media and media packs that provide robust performance in high-speed rotating coalescer (HSRC) elements for crankcase ventilation systems are described. The fiber media is HSRC fiber media. As such, the filter media has a higher resistance to compressibility then traditional coalescer filter media, such as fiber media used in low-speed rotating coalescer arrangements or stationary coalescer arrangements.
