A filter equipment includes a main body portion which has a hollow columnar structure with an open upper portion and a closed lower portion, and has a plurality of air inlets formed on a side surface to be spaced apart at regular intervals; a top cap which is detachably attached to an upper opening surface of the main body portion, and has a doughnut structure having a width corresponding to that of the filter portion in a plan view, a magnetic member attached to a lower surface of an air vent by a magnetically detachable structure being mounted on an upper surface of the top cap; a filter portion which has a hollow columnar structure corresponding to an inner peripheral surface of a main body portion, has a doughnut structure having a width corresponding to the lower surface of the top cap, has a structure that is in close contact with the lower surface of the top cap, purifies the air drawn in from the air inlet of the main body portion and then makes the purified airflow through a central opening portion of the top cap to the air vent; and a safety wire which is mounted inside the main body portion and extends by a predetermined length to be combined with one side of the top cap.

A filter and kit assembly for securing to one or more intake surfaces associated with a V-shaped heat exchanger unit. A screen includes a reinforced edge, within which is configured a plurality of spaced apart grommets aligning with and receiving therethrough engaging portions of the fasteners. In one variant, a frame is constructed for supporting the fasteners and attached filter and which is subsequently secured by clips against a flange surface surrounding the intake opening. In a further variant, the screen is configured in wrap-around fashion for supporting against first and second consecutively arranged intake openings along with an interconnecting intermediate flange surface.

An extraction arm for an extraction device includes a suction pipe and a suction head and defines a suction path that extends from an extraction region in the surroundings of the suction head through the suction pipe to the extraction device. The extraction arm includes an exchangeable filter which is arranged within the suction path. The filter is located in a filter housing which has a main body and a closable cover. The filter is exchangeable, which makes it very easy to prepare the extraction arm for a new application. Since the filter is arranged in front of the suction pipe, the suction pipe remains clean. The filter can easily be changed, whereby disinfection or cleaning of the suction pipe is not necessary.

The airflow exhaust system for a combination washer/dryer includes an exit duct portion to couple with an exit from a tub. A lint screen box portion is associated with the exit duct. A transition duct portion is associated with the lint screen box portion. A fan is associated with the transition duct. The fan includes an outlet to couple with an exhaust tube. A mounting assembly stationarily fastens the airflow exhaust system within a housing of the combination washer/dryer machine.

Apparatuses, systems, and methods are provided for and in conjunction with n external oil coalescing apparatus for receiving an air flow containing oil; a honeycomb material for coalescing oil contained in the air flow; a first end for receiving the air flow containing oil; and a second for emitting air from the apparatus.

An inflator for generating inflation gases for a safety device includes a housing having an internal cavity including a combustion chamber and a filter chamber. A filter is disposed in the filter chamber. A separating member is disposed in the housing on a first axial side of the filter and separates the filter chamber from the combustion chamber. An insulating member is disposed in the filter chamber on a second axial side of the filter. The second axial side is opposite the first axial side. The separating member is coupled to the insulating member.

Filter media having a design embossed into the media are described. In some arrangements, the filter media is pleated filter media. In other arrangements, the filter media includes a plurality of channels, such as tetrahedron channels. The filter media includes a pattern of interrupted straight or angled embossments that help maintain separation between adjacent layers of the filter media. The embossments allow for two adjacent media layers (e.g., mating surfaces of the filter media) to remain separated, thereby increasing dust holding capacity and lowering pressure drop ever similarly configured filter media not having the embossments.

An adjustable filter track system a filter track having a recess configured to receive a filter, and a frame having a first coupling feature configured to couple to the filter track in a first configuration and a second coupling feature configured to couple to the filter track in a second configuration, where the filter track and the frame are configured to hold the filter in place within the recess, and where the filter track is adjustable between the first configuration and the second configuration to accommodate different thicknesses of the filter.

A clamping system (1) for mounting a filter housing (10) to a wall structure (20), said clamping system including a filter housing clamping flange (2) arranged on a front side of the filter housing (10), and being adapted to abut a front side (20a) of the wall structure (20); a first locking plate (4, 44) having a longitudinal direction (y), and including a locking plate clamping surface (5, 45) extending along a longitudinal side of the locking plate (4) and being adapted to abut a rear side (20b) of the wall structure (20); a first engagement component (3a, 43a) associated with a filter housing wall (11) on a distance from the filter housing clamping flange (2); and a puller (6), said locking plate being configured to cooperate with the puller (6) via an abutment surface (7) associated with the locking plate (4; 44) and being adapted to engage with a part of the puller (6), and said locking plate (4; 44) further being configured to cooperate with the first engagement component (3a, 43a) via a second engagement component (8a, 48a) arranged in the locking plate, wherein one of said first and second engagement components (3a, 43a; 8a, 48a) is a retainer bracket (12a, 42a), and the other of said first and second engagement components (3a, 43a; 8a, 48a) is a push edge (13a, 46a) comprised in a push opening (14a, 50), said push edge (13a, 46a) being an inclined edge adapted to engage with the retainer bracket, said puller (6) being configured to manipulate the abutment surface (7, 47) so as to move the locking plate (4, 44) in the longitudinal direction thereof, such that the inclined push edge (13a, 46a) of the push opening and the retainer bracket (12a, 42a) interact to push the locking plate (4) in a transverse direction thereof and toward the filter housing clamping flange (2), thus clamping the wall structure (20) between the filter housing clamping flange (2) and the locking plate clamping surface (5, 45).
