    Abstract: An air cleaner assembly with a restriction indicator includes a housing having an exterior surface around an interior volume. The housing includes a bore extending through a portion of the exterior surface of the housing surrounded by a bore wall protruding from the portion of the exterior surface. A receptacle wall of the housing is disposed around the bore wall and is radially spaced from the bore wall to form a channel between the bore wall and the receptacle wall. A restriction indicator measures a restriction in the interior volume and displays an indication of the restriction. The restriction indicator includes a stem that is at least partially insertable into the bore that engages an inner surface of the bore wall. One or more tabs of the restriction indicator are at least partially insertable in the channel and removably couple to the receptacle wall.

    Abstract: A filter assembly comprising a first body coupled to a second body via a hinged connection to rotatably couple the first and second bodies together. The assembly further comprises a releasable connection releasably coupling the first and second bodies together. The assembly further comprises a filter coupled to at least one of the first and second bodies and configured to prevent solids from flowing through the filter while allowing fluid flow through the filter. The filter assembly is configured to be coupled to a dispensing pipe of a dosing device and a fill pipe of a packaging system.

    Abstract: A gaseous fluid filter has a filter element insertable into the filter housing through a service opening. A clamping wedge is insertable in a joining direction for clamping the filter element in clamping direction against the filter housing. The filter element rests against the filter housing with a seal surface facing away from the clamping wedge. The clamping wedge has a housing wedge side facing a housing stop and a filter element wedge side facing a filter element stop. These wedge sides each have first and second bearing surfaces separated by a step. The joining direction extends in or parallel to a contact plane between housing wedge side and housing stop. The first and/or second bearing surface of the filter element wedge side is positioned at a wedge base angle of 1° to 20° to the joining direction. The steps of the wedge sides are offset in joining direction.

    Abstract: A filter element includes a frame having an outlet panel and two side panels defining a U-shape. A U-shaped media anchor channel extends along the distal side edge of each panel. Each media anchor channel can have a snap-tab or other locking feature. The element encloses a pleated panel filter media pack having a side edge along each side of the pack. Each side edge of the media pack is located in a media anchor channel, and a bead of adhesive is applied along the channel. A pair of seal bars, each having a u-shape and a snap-tab or other feature that cooperates with the u-shape and the snap-tab of each media anchor channel, is pressed into each channel. Each seal bar mechanically retains a respective media side edge in the channel and together with the adhesive, provides a consistent, robust seal between the media and the frame.
