Abstract: An air cleaner assembly includes a filter housing extending axially along a longitudinal axis and a cover. The filter housing includes at least one sidewall (e.g., an annular sidewall) extending between a first housing end and a second housing end and a retainer formed proximate at least one of the first housing end and the second housing end. The cover is removably coupled to at least one of the first housing end and the second housing. The cover includes a handle assembly having a latch configured to releasably engage the retainer of the filter housing. The filter element includes filter media and is axially insertable into the filter housing when the cover is removed from the filter housing.

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: Inertial particle separators having an axially translating or a deformable poppet component are described. The poppet component axially translates to accommodate a wide range of flowrates through the inertial particle separator. In some arrangements, the poppet component is biased by a spring towards a closed or restricted position. The variable flowrate and constriction provided by the poppet maintains a substantially constant pressure drop and separation efficiency during operation across a wide range of flowrates through the separators.

Abstract: Filtration systems having a tangential air cleaner having a coiled media filter element and a cyclonic pre-cleaner are described. An outer wall of the filter element acts as a pre-cleaner sleeve of the housing to generate a cyclonic flow of the intake air prior to the intake air being filtered by the filter element. The housing cover includes geometry that redirects the cyclonic flow from a tangential path to an axial, straight-through flow directed through an inlet flow face of the filter element. Various embodiments of such filtration systems offer increased filter performance and capacity compared to similarly sized cylindrical pleated filter elements having a radial flow filtering path.
Abstract translation: 描述了具有切线式空气净化器的过滤系统，所述切向式空气净化器具有卷绕介质过滤元件和旋风式预净化器。 过滤元件的外壁用作壳体的预清洁器套筒，以在吸入空气被过滤元件过滤之前产生进气的气旋流。 壳体盖包括将旋风流从切向路径重新引导到被引导通过过滤器元件的入口流动面的轴向直通流的几何形状。 这种过滤系统的各种实施例与具有径向流动过滤路径的类似尺寸的圆柱形折叠式过滤元件相比提供了增加的过滤性能和容量。

Abstract: Various example embodiments relate to a filtration system. The filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing comprises a first alignment portion disposed on the first housing end. The filtration system further comprises a filter element positioned within the central compartment of the housing. The filter element has a first filter end and a second filter end. The filter element comprises filter media and a second alignment portion disposed on the first filter end. The second alignment portion is complementary to the first alignment portion. The installation of the filter element within the housing causes the first alignment surface and the second alignment surface to align to provide for engagement of a radial seal between the filter element and the housing.

Abstract: A filter assembly includes a support frame, a filter media, and a conditioning device. The filter media is coupled to the support frame. The filter media has a dirty side that receives an air stream and a clean side that outputs the air stream after having been filtered by the filter media. The conditioning device is coupled to the support frame. The conditioning device is positioned downstream of the clean side of the filter media with respect to the air stream and directly contacts the clean side of the filter media.

Abstract: An air filter assembly comprises a housing, a filter element and a permeable baffle. The housing comprises an outer wall with a substantially cylindrical inner surface, an inlet, and an outlet. The inlet is positioned along and extends through the outer wall. The outlet is positioned along and extends through an axial end of the housing. The filter element comprises a filter media with a substantially cylindrical outer surface. The filter element is positionable within the housing. The permeable baffle is positioned between the inlet and the filter element. The permeable baffle allows at least some air to flow therethrough.

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.
