The present invention is disinfecting air filtration apparatus that allows multiple disinfecting air filtration modules to function in parallel. The apparatus may provide energy to respective parts of a filtration apparatus, such as a V-Bank filter apparatus. The apparatus may also include a front-mounted pre-filter frame that can be secured to other parts of the apparatus without tools. The securing of the pre-filter frame grounds the air filtration module and creates an airtight interface between the air filtration module and the array. Methods consistent with the present disclosure allow for filter apparatus to be connected to or coupled to virtually any size air ducts of an air distribution or a high voltage alternating current air conditioning (HVAC) system.

A filter element having a filter media pack with an inlet end, outlet end, and outer periphery extending therebetween. The inlet and outlet ends are separated along an axis. The outer periphery includes a first pair of opposed sides between the inlet and outlet ends, and a second pair of opposed sides extending transversely between the first pair of opposed sides. A frame supports the outer periphery, having opposing first frame side segments, and a second frame segment. Each first frame side segment includes a pair of guide projections extending along respective first sides. The guide projections are spaced apart from one another from a broad end at one second side, to a narrow end at the other second side, and arranged to receive axial forces received within a housing having complementary engagement surfaces. A housing seal is supported along one guide projection, sealing against the complementary engagement surfaces.

A pocket filter comprising a plurality of filter pockets, a frame holding the filter pockets, and at least one clamping strip fixing filter layers of two neighboring filter pockets. A profile of the clamping strip is designed in one piece and has a first section and a second section that are movably connected to one another, a T-shaped locking element is formed on the first section, and the T-shaped locking element has a base and a cross-piece extending substantially perpendicularly to the base. A proximal hook-shaped locking element and a distal hook-shaped locking element are formed on the second section, between which the T-shaped locking element is arranged and which engage behind the cross-piece when the clamping strip is in a locked state in which the filter layers of the two neighboring filter pockets are clamped in the clamping strip.

A fluid filter has a filter housing with inlet opening for fluid to be cleaned and outlet opening for cleaned fluid. A filter element arranged in an element receptacle of the filter housing separates inlet opening from outlet opening. The filter housing has a housing body with an installation opening to the element receptacle, through which the filter element in an installation direction is introduced into the element receptacle. The filter housing has a housing cover for closing the installation opening. The installation opening is arranged in a transverse side of the housing body that is lateral relative to the housing axis. The filter housing has a sealing surface, surrounding the housing axis at least partially circumferentially, for contacting a seal of the filter element. The filter element has a seal support device for the seal and the filter housing has a pressing device for the seal support device.

A filter for a vacuum cleaner includes a top having an open center, a bottom plate having an outermost edge, a center, an inside surface facing towards the top, an outside surface facing away from the top, and a catch extending from the inside surface annularly around the center, filter material being secured between the top and bottom plate. An adaptor for a filter cage or the filter cage itself includes a radial retention ring that engages the catch of the filter.

An air cleaner assembly is disclosed, along with related methods. In one aspect, the air cleaner assembly has a housing including a housing body and a removable cover that together define an interior volume for holding a filter cartridge. The housing can include a first part of a first connection arrangement. The air filter cartridge can include a second part of the first connection arrangement. In one aspect, the first and second parts can be secured together place the air filter cartridge in a latched position by moving the air filter cartridge in a first direction. In one aspect, the first and second parts can be disconnected from each other to place the air filter cartridge in an unlatched position by moving the air filter cartridge in the first direction. The air cleaner assembly can include a second connection arrangement securing the air filter cartridge to the housing cover such that the housing body and housing cover are secured together.

The pocket channel frame provides a means for attaching the distal ends of a pocket frame without the need of any tools. The pocket channel frame is formed from a longitudinal member having an elongated “C” shaped cross section. One end comprises is a flared out female end with a rectangular slot or 5 hole in it. The opposing distal end of the longitudinal having a C shaped cross section is swaged down into a projecting male end including a lance punched in the web. When the male end is swaged, an edge is created in the transition area from male to female which acts as a stop means for cooperatively engaging the female receiving distal end and sets the length of a short side of the pocket channel frame. During assembly, the lance snaps into the hole cooperatively engaging the slot on the 10 female side preventing the channel frame from coming back apart.

A filter for compressed air systems is provided. The filter includes a filter housing with a filter therein between an air inlet and an air outlet. Compressed air flowing between the air inlet and the air outlet passes through the filter housing and the filter element. A base is removably fastened to the filter housing which may be separated from the filter housing to allow the filter element to be removed and replaced.

A filtration device may include a filter element and a housing that is configured to receive the filter element. The filter element may include a casing having a first outer surface and a flange connected to the first outer surface. The flange may include a plurality of snap members. A snap member, of the plurality of snap members, may include a fulcrum projecting from the flange and a lever mounted on the fulcrum. The housing may include a shell having a second outer surface and a plurality of ramp members. The plurality of ramp members may be fixedly connected to the second outer surface and may be configured to engage the plurality of snap members of the filter element. A ramp member, of the plurality of ramp members, may include an angled surface that extends from the second outer surface at an acute angle relative to the second outer surface.

A filtration device may include an adapter, a filter element, and a housing. The adapter may include a collar having an upper rim and a lower rim, a plurality of locking tabs extending from the upper rim, and a plurality of snap members extending from the lower rim. The filter element may include a casing and a plurality of receptacles connected to and arranged around a first outer surface of the casing. The plurality of receptacles are configured to receive the plurality of locking tabs. The housing, which is configured to receive the filter element, includes a shell and a plurality of ramp members that are connected to a second outer surface of the shell. The plurality of ramp members are configure to engage the plurality of snap members.
