Abstract: Filter media having generally tetrahedral shaped flow channels is described. The filter media is generally formed by a flat filter sheet and a formed sheet. The formed sheet may be formed by a curves and/or pleats in the sheet. The curves and/or pleats form the tetrahedron channels. Embossments, such as dimples, are provided on the crests formed by the curves and/or pleats. The embossments help to maintain spacing between adjacent layers of the filter media, thereby increasing dust holding capacity and decreasing pressure drop over similarly configured filter media not having the embossments.

Abstract: A filter assembly includes a conditioning device that conditions a flow of air upstream of a mass air flow sensor. The filter assembly includes a support frame. The filter assembly further includes a filter media coupled to the support frame, the filter media having a dirty side configured to receive a stream of air and a clean side configured to output a stream of air that has been filtered through the filter media. The filter assembly includes a conditioning device coupled to the support frame, the conditioning device positioned in a downstream direction from the clean side of the filter media with respect to the stream of air, the conditioning device offset from the clean side of the filter media by a separation distance.

Abstract: Filter media including one or multiple sheets of filter media, an upstream inlet, and a downstream outlet. A pleat pack can be formed by alternately folding a flat sheet along pleat fold lines with a high media surface density. The flat sheet of filter media may include a separation geometry feature or separation mechanism that maintains a separation distance between adjacent pleats of the filter media. A separation geometry can comprise one or more embossments forming a raised surface, an inlet spacer mesh and/or an outlet spacer mesh positioned between adjacent pleats, and/or an adhesive bead. The upstream inlet receives dirty fluid along a first direction and the downstream outlet discharges clean fluid along a second direction substantially not parallel to the first direction. The filter element defines an angle between the inlet and outlet flow, allowing large dust particles to move out of the media pack due to inertia.

Abstract: Various rotating coalescer elements are described. The rotating coalescer elements include various arrangements of stacked separator discs or cones. In some arrangements, the described rotating coalescer elements include a combination of stacked separator discs or cones and filter media. In some arrangements, the stacked separator discs are designed to provide the largest possible amount of radial-projected separation surface area in a given rotating cylindrical volume, where flow to be cleaned is passing radially (outwardly or inwardly) through the rotating coalescer element. In some arrangements, this is achieved by stacking non-conical separating plates containing various area-maximizing features (e.g., spiral ribs, axial cylinders, spiral grooves, or spiral “V” shapes).

Abstract: A gas-liquid separator includes a housing. The housing includes an inlet structured to receive a blowby gas stream from a crankcase. a cleaned air outlet, and a liquid outlet. A cover is disposed downstream from the inlet and upstream from the liquid outlet. The cover includes a baffle disposed over the blowby gas stream flow path from the inlet. The blowby gas stream impacts the baffle and separates liquid and aerosol contained in the blowby gas stream. A flange extends substantially axially downward from a side of the baffle. The flange is tapered substantially axially downward forming an inner surface. The inner surface is structured to route the separated liquid toward the liquid outlet. The inner surface biases separated liquid away from shedding toward the cleaned air outlet.
