The buffer unit is mounted in the second receiving section of the housing and includes a positioning ring secured in the retaining portion of the housing, and a cushioning member mounted in the positioning ring. The cushioning member is elastically movable in the positioning ring. When the cushioning member is compressed by a force, the cushioning member is contracted and elastically deformed toward the second receiving section of the housing, to form a buffering force.

A duct opening portion structure includes an air intake duct; a filter that is disposed in an opening portion at an air introduction side of the air intake duct; and a bezel that is disposed in the opening portion at the air introduction side of the air intake duct, the bezel being configured to support the filter. The bezel is attached to a vehicle body-side member, and the bezel includes a rib including a support portion configured to support the filter. The filter is attached to the support portion. The rib is provided with an extension portion having a length that allows the extension portion to be directly or indirectly pressed against a seal member provided at an edge of the opening portion in a state where the bezel is attached to the vehicle body-side member.

The disclosure relates to a sealing arrangement comprising a gasket arranged to seal a gap formed between a first element and a second element, wherein the gasket is arranged to be located in the gap and to be in contact with the first and the second elements, where the gasket comprises two elongated gasket members located on a distance from each other so as to form an intermediate gasket space confined by the gasket members and said first and second elements, and in that the sealing arrangement further comprises a pressure source adapted to apply a pressure on the intermediate gasket space, said pressure source preferably being configured to maintain a set pressure difference towards the surroundings. The disclosure further relates to a method, a system, a computer program product arranged to perform the method, a further sealing arrangement and a further method of monitoring sealing integrity of a pharmaceutical production space.

An air filtration apparatus includes an airflow powerhead assembly including a fan assembly and a vane assembly, a filter assembly, and a separator chamber housing inside of which the filter assembly is disposed. The separator chamber housing has a chamber inlet at a first axial side and a clean air outlet at a second axial side of the separator chamber housing opposite the first axial side. The filter assembly has a first axial end adjacent the chamber inlet and a second axial end adjacent the clean air outlet. The separator chamber housing includes at least one debris ejection slot extension configured to eject debris from an inner space of the separator chamber housing. The filter assembly includes a debris catch tray disposed at the second axial end, the debris catch tray having a debris ejection slot aligned with the at least one debris ejection slot extension.

An air filter includes: a pleated filter material folded into a zig-zag form at folding lines along a first direction to have peak parts and valley parts arising alternately in a second direction perpendicular to the first direction, trapping fine particles in a gaseous matter flowing in a gas flow direction perpendicular to the first direction and the second direction; a filter frame being a rectangular filter frame including one pair of first frame materials facing each other in the second direction having end parts in the first direction, and one pair of second frame materials facing each other in the first direction having end parts in the second direction, opening in the gas flow direction and housing the pleated filter material, each of the first frame materials and each of the second frame materials being combined to provide an overlap part.

An air cleaner system including a housing having a first housing end with an opening, a second housing end, and an inlet proximate the second housing end. The air cleaner system also includes a filter element removably installed within the housing through the opening, the filter element including filter media, a first endplate coupled to the filter media at a first filter end, an open second endplate coupled to the filter media at a second filter end, and an annular projection extending axially from the open second endplate, the annular projection sealing against the housing and creating an axial gap between the filter element and the housing.

A filter cartridge for an air cleaner assembly is disclosed. The filter cartridge can include a media pack configured for installation into an air cleaner housing, the media pack extending along a longitudinal axis between opposite inlet and outlet flow ends, the media pack defining an outer perimeter. The filter cartridge can also include a circumferential shell surrounding at least a portion of the media pack outer perimeter. A radial flange extending from the circumferential shell proximate the media pack inlet end can also be provided. The flange can define a plurality of openings that are configured to receive protrusions on a housing body of the air cleaner assembly. The interaction between the protrusions and openings operates to ensure a secure seal between the housing body and the seal member.

A filter element, in particular a replaceable filter element, more particularly for separating particles and/or gases and/or liquids, in particular a filter cartridge for use in a filter, more particularly a compressed air filter, in particular as a component of a filter comprising multiple filtration stages, includes a substantially tubular body with an annular end face that faces a filter head, an underside, and a circumferential surface. Multiple, preferably four, retaining arms, running radially in relation to the central axis, are provided in the region of the end face and a toroidal filter-element sealing surface is provided on the end face, and the retaining arms protrude in relation to the filter-element sealing surface. The filter element is usable in a filter.

A compressor system includes a compression module having an inlet for receiving air; and a filter housing in fluid communication with the compression module. The filter housing is constructed to house a filter, the filter having a sealing feature disposed at a first end of the filter and having an engagement feature disposed at a second end of the filter opposite the first end. The filter housing includes a trap door constructed to contact the engagement feature, and constructed to drive the engagement feature in a direction parallel to an axis of the filter toward the sealing feature and urge the sealing feature into sealing engagement with the filter housing.

A filter assembly comprises a filter element, and a mount having at least one port. Each of the filter element and mount has inter-engaging connection formations, where the filter element and mount can be detachably connected to one another. The mount defines a flow path between the port and filter element when the element is connected to the mount and includes a link element which can slide relative to the mount between retracted and deployed positions. The link element has one of a lug and an inclined ramp surface, and the filter element has the other of the lug and ramp surface. The lug and ramp surface form a cam drive where the lug engages the ramp surface as the filter element and mount are assembled, and slide along the surface when the element is rotated to draw the link element out of the mount towards its deployed position.
