Abstract: Rotating coalescer crankcase ventilation (CV) systems are described. The described CV systems utilize a pumping pressure created by the porous media of the rotating coalescer to maintain positive recirculation of filtered blowby gases through a potential leak gap between a static housing inlet and a spinning component of the rotating coalescer. In some arrangements, the porous media is fibrous media. The filter media may be pleated or non-pleated. The positive recirculation caused by the pressure balance prevents unfiltered blowby gases from bypassing the media of the rotating coalescer from the upstream side to the downstream side of the filter media through the gap. During operation, the pressure balance between the upstream side and downstream side of the filter media maintains the positive recirculation, which in turn maintains a high filtration efficiency.

Abstract: A filter element comprises a filter media and a restriction indicator device. The restriction indicator device comprises an attachment portion and a movable portion. The attachment portion is attachable to a portion of the filter assembly. The movable portion is movable relative to the attachment portion between a non-buckled position and a buckled position. The movable portion moves from the non-buckled position to the buckled position once a predetermined pressure drop between an upstream side and a downstream side of the movable portion of the restriction indicator device is met.

Abstract: A filtration assembly includes a housing. The housing includes a first housing for fluid and a second housing opening for fluid. A containment cover is removably coupled to the housing. The containment cover defines a cover opening, a cover surface, and a flow passage. The cover opening is in fluid communication with the housing. The cover surface is substantially continuous around a circumference of the containment cover. The cover surface includes an open portion in fluid communication with the second housing opening. The flow passage is formed by a first passage surface and a second passage surface. The flow passage includes a first end in fluid communication with the cover opening. A second end is in fluid communication with the second housing opening through the open portion of the cover surface. The flow passage extends radially outward from the cover opening.

Abstract: An external brace for a filter element is described. The brace is configured to wrap around an exterior of a filter element having a filter media pack. The brace helps to support the filter media pack during filtering operations by preventing outward flexing of the filter media pack caused by fluid flowing through the filter media. In some arrangements, the brace interfaces with a filtration system housing to provide additional support to the filter element.

Abstract: A separation assembly comprises a housing, a jet that expels a fluid within the housing, and a turbine positioned within the housing. The fluid causes the turbine to rotate about a center rotational axis within the housing. The turbine comprises a first axial end, a second axial end, and a plurality of vanes extending axially relative to the center rotational axis from the first axial end to the second axial end. The plurality of vanes defines axially-extending channels between each of the plurality of vanes. The first axial end comprises a radially-extending structure that axially blocks the flow of the fluid through the first axial end. The second axial end does not comprise any structure that axially blocks the flow of the fluid through the second axial end.

Abstract: A no filter no run bidirectional pin element is disclosed. A shell housing is removably coupled to a filtration housing, a removable no filter no run attachment, and a filter element. The filter element comprises a filtration media and a bidirectional pin element. The bidirectional pin element comprises a center tube formed as a single piece with a bidirectional pin. The installation of the filter element and the shell housing into the filtration system results in the bidirectional pin entering a pin aperture of the removable no filter no run attachment and the bidirectional pin preventing the operative engagement of a blocking element with a divider inside the no filter no run attachment.

Abstract: Filter housings that have housing wall surface irregularities are described. The surface irregularities are positioned on the inner walls of the housings and/or axial ends of the housing walls. The surface irregularities may be, for example, grooves, ribs, bumps, and the like. The surface irregularities provide an engine integrity protection (EIP) feature by preventing non-approved replacement filter elements from forming seals against alternative sealing surfaces of the housing wall inner surfaces or axial ends.

Abstract: An air intake system having an air filter and a cyclonic pre-cleaner is described. The cyclonic pre-cleaner includes a plurality of fins that cause the air flowing through the pre-cleaner to go from a substantially axial flow to a substantially swirling flow. As the air flow through the pre-cleaner increases, the air is swirled at a faster rate, and some contaminant particles in the air will be forced out of the flow of air before reaching the air filter. The air intake system includes a blower unit having a motor, an impeller, and a controller. The blower unit structured to selectively draw more air through the air intake system to increase the flow of air through the pre-cleaner thereby increasing the efficiency of the pre-cleaner.
