A gel-sealed air supply box includes an air inlet and a box body, wherein the box body is internally provided with a filter. A plurality of filter profiles that are sequentially connected are arranged on the inner side surfaces of the box body, and a corner dust generating pipe is arranged between two filter profiles. A dust distributing pipe is arranged at the top end of the filter profile, and the dust distributing pipe is communicated with the corner dust generating pipe. A plurality of dust holes are formed in the top end of the dust distributing pipe. According to the disclosure, dust can be uniformly generated and a more precise detection result can be achieved.

A filter support for mounting an air cleaning device includes an access panel, at least one support member extending from the access panel, and a latch mounted to the access panel. The latch is operable to selectively couple to the air cleaning device.

A filter element has a filter media assembly extending between a first end and a second end to define a media length along a longitudinal axis. The filter media assembly defines a central opening on an upstream side and an outer radial boundary on a downstream side. A first endcap is coupled to the first end. The first endcap has a media potting structure defining an annular surface abutting the first end of the filter media assembly, an inner tubular flange extending longitudinally from the annular surface into the central opening, and an outer tubular flange extending longitudinally from the annular surface over the outer radial boundary of the first end of the filter media assembly. The first endcap has an outer circumferential sealing surface about the longitudinal axis and a shroud to obstruct fluid flow extending longitudinally from the outer circumferential sealing surface towards the second end.

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.

An air filter element inlcudes a first end and a second end located opposite to the first end in relation to a longitudinal direction of the air filter element. The air filter element is configured for axial insertion into a filter housing with the first end leading the axial insertion. The air filter element inlcudes a gripping structure at the second end, the gripping structure comprising an external surface accessible for interaction by a tool to facilitate removal of the air filter element from the filter housing. The gripping structure is also configured to, during insertion of the air filter element into the filter housing, radially align the air filter element in the filter housing.

The present invention relates to filter housing (12) of a filter (10) for a fluid and a filter (10). The filter housing (12) comprises a housing body (24), which is comprising at least one openable installation opening and at least one housing cover (26), which is configured to close off the at least one openable installation opening, and at least one fastening and/or locking device (186), which is configured to secure the at least one housing cover (26) in its closed position in the housing body (24). The housing body (24) comprises an element receptacle configured to receive, through the at least one openable installation opening at least one filter element. At least one fastening and/or locking device (186) has at least one U-shaped bracket element (188), whose arm sections (206) are connected to a cross beam (192), and at least one eccentric element (187) which is mounted rotatable with respect to a rotation axis (190) on the cross beam (192). The at least one bracket element (188) can pivot with respect to a bracket pivot axis (196) such, that the cross beam with the at least one eccentric element (187) is pivotable on the side of the housing body (24) with the at least one installation opening. In a closed position the at least one eccentric element (187) is engaged with the at least one housing cover (26) and the at least one bracket element (188) grips around the housing cover (26) such, that a part of the housing cover (26) is located between the arm sections (206) of the bracket element (188).

A filter support for a filter is adjustable to modify the size and/or shape of the filter. The filter support may include one or more wedges engaging a wall of the filter, and a connector connecting the one or more wedges to one another. The connector allows selective adjustment of the filter support.

Disclosed herein is an air cleaner disposed in an indoor space. An air cleaner according to an embodiment includes a blowing device including a suction port and a discharge port, a fan motor configured to generate an air flow, a purifying unit installed inside the blowing device to purify air, a driving portion configured to move the air cleaner, a communication unit configured to communicate with a moving agent moving in the indoor space, and a processor configured to receive status information including at least one of air quality information and dust occurrence information collected by the moving agent, determine a specific zone in which air purification is to be performed using the status information collected by the moving agent, and perform air purification in the specific zone.

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.

An air purifying system includes first, second, and third air purifiers controlled independently and a docking station having first, second, and third supports configured to support and charge the first, second, and third air purifiers. The docking station has a vertical backbone, and the first, second, and third supports horizontally extend from the backbone. At least the second and third air purifiers are configured to be separated from the docking station and include handles to assist a user in transporting the second and third air purifiers to separate rooms or indoor spaces.
