A filter assembly comprises a filter element and a housing. The filter element comprises a filter media, and an alignment feature positioned on at least a portion of an outer surface of the filter media. The alignment feature comprises an alignment channel. The housing defines a housing internal volume. At least a portion of the filter element is positioned within the housing internal volume. The housing comprises an alignment protrusion extending axially from a housing inner surface towards the filter element so as to mate with the alignment channel. The alignment feature comprises a ring member positioned circumferentially around the filter media at a filter media first end proximate to the housing, and a filter baffle extending from the ring member. The filter baffle is circumferentially positioned on at least a portion of the outer surface of the filter media and defines the alignment channel.

An air cleaner assembly is disclosed. In one aspect, the air cleaner assembly includes a housing defining an inlet and an outlet, and including an access opening between the inlet and outlet. The air cleaner also includes a filter cartridge received within the housing and covering the access opening. The air cleaner also includes a lock mechanism. The lock mechanism is movable between an unlocked position in which the filter cartridge can be installed and removed from the housing and a locked position in which the filter cartridge is secured within the housing. The filter cartridge and lock mechanism include interacting features allowing the lock mechanism to be moved from the unlocked position to the locked position only when the filter cartridge is installed within the housing.

A liquid separator comprises a vessel with an inlet for a liquid/gas mixture. The vessel defines a space sealed at the top by means of a lid in which is situated an outlet to discharge treated gas. A shield is provided in the space extending around the outlet as of the lid, and a filter element provided within the shield. An outlet zone is defined between the shield and the filter element, wherein the outlet zone is in connection with the outlet. The shield comprises a bottom wall with at least one inlet opening and connection means for attaching the filter element onto the bottom wall. The connection means is configured such that the filter element, in a mounted condition, extends around the inlet opening as from the bottom wall, within a chamber defined by the shield, the lid and the bottom wall.

A dust collector includes an enclosure and a tube sheet separating filter and clean air compartments. The tube sheet forms a filter opening and a filter is located within the filter compartment and includes a filter flange having an air outlet aligned with said filter opening. The flange includes first and second alignment structures located on a first lateral side of the flange. A clamping assembly includes first and second filter clamps that are movable between a sealing position for sealing the filter flange against the tube sheet, and a release position. The first filter clamp engages the first alignment structure when in the sealing position. The second filter clamp engages the second alignment structure when in the sealing position. The dust collector includes means for moving the filter clamps between the sealing position and the release position.

In one embodiment, a material sorting system comprises: a suction gripper assembly, the suction gripper comprising: a body assembly that includes: an internal airflow passage configured to communicate an airflow between an airflow application port positioned at a first end of the body assembly and a gripping port positioned at the opposing second end of the body assembly; a cup fitting attached to the gripping port; a suction cup secured to the cup fitting; an attachable filter inserted into the suction cup and fastened to the cup fitting; and a mounting assembly, wherein the mounting assembly includes one or more mounting points for pivotally attaching the suction gripper assembly to a sorting robot of the material sorting system.

A filter bank includes a filter enclosure. A first filter panel and a second filter panel are flexibly joined along respective proximal ends of the first filter panel and the second filter panel by a living hinge. A first sealing gasket extends along a distal end of the first filter panel and forms a first air seal within the filter enclosure. A second sealing gasket extends along a distal end of the second filter panel and forms a second air seal within the filter enclosure. A third sealing gasket extends along the living hinge. A pivoting sealing rail pivots within the filter enclosure to form a third air seal against said third sealing gasket extending along the living hinge

An air cleaner includes a housing and an access cover. The internal volume of the housing can be reached through an opening in a side wall of the housing. A filter element having fluted filter media is removable and replaceable from the air cleaner. The housing is constructed and arranged to cam the element into sealing engagement with the housing. The access cover includes structure to help support and ensure proper seating of the filter element within the housing. A method of installing the filter element in the air cleaner includes sliding a portion of the filter element against a slide surface in the housing. A method of servicing an air cleaner includes tilting the filter element against a tilt surface in the housing to release a seal between the filter element and the housing. The filter element can have a handle to assist in servicing of the air cleaner. The housing can have a window to allow visual inspection of the internal component of the housing and to determine visually whether a filter element is installed therein.

An air cleaner arrangement or assembly is provided. The air cleaner arrangement includes a serviceable filter cartridge. The air cleaner assembly also includes an arrangement for positioning the filter cartridge into a preferred, sealing, orientation and for securing the filter cartridge in that location. Preferred serviceable filter cartridges are provided, as well as methods of assembly and use.

An air freshener is disclosed. The air freshener includes a body case defining the air freshener, the body case having a filter installation opening formed in one side thereof, a filter housing disposed in the body case, a drawer including a frame forming therein a drawer opening, through which air passes, and a filter cover coupled to the frame for covering the filter installation opening, and a filter module separably located on the frame for filtering the air that has passed through the drawer opening. The drawer is configured to be withdrawn from the inner space of the filter housing through the filter installation opening.
