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.
