Air cleaner and preferred components for an air cleaner are provided. In certain arrangements, a band is mounted to the media pack, surrounding the media. Also, the cartridge is non-circular and includes a seal thereon.

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.

The present disclosure relates to a filter housing having a bowl and a head. The bowl is configured to house a portion of a filter cartridge. The bowl has an annular groove disposed about a rim of the bowl. The head is configured to mate with the bowl. The head includes an inlet, outlet, and a pair of levers. The inlet is to receive a flow of fluid into the filter housing. The outlet is to release the flow of fluid from the filter housing. The pair of levers are to draw the bowl partially into the head. Each lever has a first arm configured to mate with the annular groove, a second arm having a bearing surface, and a pivot disposed between the first arm and the second arm. A force upon the bearing surface urges the bowl into the head to form a seal.

An air filter element for an air filter for an internal combustion engine is provided with a filter medium surrounding annularly a longitudinal axis of the air filter element. A first end disk is provided at a first end face of the air filter element, wherein the filter medium is embedded in the first end disk at the first end face. A clean air seal is configured to seal a raw side of the air filter against a clean side of the air filter. The clean air seal and the first end disk are embodied together as one piece. The clean air seal protrudes continuously radially past the filter medium. A filter housing for the air filter element is provided with a filter pot and a cover and has a clean air outlet and a raw air inlet arranged at a side wall of the filter pot.

A side-covered axial flow filter has a housing, a filter core, a filter frame, and a side cover. When assembling, the filter frame and the filter core are both obliquely installed into the housing. Limiting ribs of the filter frame are obliquely mounted between first pushing panels and a clamping surface of the housing, and inner pushing parts of the limiting ribs abut the first pushing panels. The portions of the inner pushing parts abutting the first pushing panels serve as fulcrums to straighten the filter core and the filter frame, so outer pushing parts of the limiting ribs may abut the clamping surfaces of the housing and generate a strong torque and a tightly sealing effect without much effort. The side cover also abuts the filter frame when assembled on the housing, so the filter frame is under balanced pressure to avoid leak.

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.

A filter device has a filter element (1) received in a filter housing of at least two interconnectable housing parts (17, 19). The filter element (1) can be fixed to a housing part (19) in a removable manner by one screw connection (32, 33). An additional screw connection (17, 41) is provided for connecting the housing parts (17, 19). To transmit a torque between threaded elements (33) of the one screw connection (32, 33) and of the additional screw connection (41), the threaded elements are rotatable relative to each other. A coupling device (43, 46, 61) is added that allows an additional rotational movement of the threaded element (17) of the additional screw connection (41) when the threaded element (33) of the one screw connection (32, 33) reaches the fixed rotational state.

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.

An air filter, an air filter assembly, and method of installing the air filter into a housing of the air filter assembly are provided. The air filter includes an attachment portion and a lock tab. The lock tab is carried by and resiliently moveable relative to the attachment portion. The lock tab is located radially outward from the attachment portion and movable circumferentially about a central axis of the air filter. Another feature relates to using an end stop in a housing as a catch. Yet another feature relates to using a perforated end cap and capping such perforations with a housing seal.

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 filer 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.
