  • Patent number: 11701606
    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.

  • Publication number: 20170028330
    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.

  • Patent number: 9138671
    Abstract: A gas-liquid separator has a housing having an inlet for receiving a gas-liquid stream and an outlet for discharging a gas stream. A nozzle structure in the housing has a plurality of nozzles that receive the gas-liquid stream and accelerate the gas-liquid stream therethrough to create a plurality of gas-liquid jets. An inertial collector in the housing causes a sharp directional change of the gas-liquid jets, causing separation of liquid particles from the gas-liquid stream to produce the gas stream. The inertial collector has a porous collection substrate. According to the present disclosure, at least one of the following three conditions is met: (a) the porous collection substrate comprises fibers of small diameter and has low packing density; (b) the porous collection substrate comprises oleophobic fibers; and (c) the nozzle structure and the inertial collector are configured to allow for full expansion of the plurality of gas-liquid jets.
