The present invention relates to an air filter housing for supplying air to a space, said air filter housing being configured to be arranged in a ceiling of said space, said housing having a mouth facing downward, said mouth comprising a sealing surface configured to receive a panel type air filter comprising a frame and a filter medium held within said frame, such that a sealing connection between said sealing surface and said frame is achieved, characterized in that said filter housing further comprises at least one resilient member arranged below the sealing surface such that when a panel type air filter is inserted into the mouth, the resilient member will be deformed by the filter frame as the filter passes the resilient member, and resume its original shape once the filter has passed, such that the filter is retained between the sealing surface and the resilient member. The present invention further relates to the use of a filter housing in a cleanroom, and to a method of mounting a panel type air filter in an air filter housing.

An air filter group for air supply to internal combustion engines of motor vehicles, of a type comprising an external casing provided with an inlet opening of the air to be filtered, and an outlet opening of the filtered air, and a removable cover, the inlet and outlet openings being separated by a removable filter cartridge which comprises a hollow cylindrical filter wall crossed by the air in a centripetal direction, in which the at least a filter cartridge is fixed to the cover in which cover a chamber is present, delimited by a base provided with at least a hole at which the at least a cartridge is fixed, by an opposite wall to the base and by an annular wall located between the base and the opposite wall and comprising the outlet hole of the filtered air, the cover being destined to be inserted sealedly in the casing.

A filter element (3), in particular an air filter element, for a filter arrangement (1), having a frame (6) that has at least one contact surface (11) for contacting a clamping surface (30) of at least one clamping element (27, 28) of the filter arrangement (1), wherein the at least one contact surface (11) includes straight segments (12, 13, 14) and oblique segments (15, 16) arranged between the straight segments (12, 13, 14), and wherein the straight segments (12, 13, 14) are arranged such that the clamping surface (30) when the latter is displaced relative to the at least on contact surface (11) essentially exclusively contacts the oblique segments (15, 16).

Disclosed herein are replaceable filter frame gaskets and air filters having the same. The gasket is secured elastically to a filter frame of the air filter, making the gasket easily reusable and removable from the air filter.

The invention relates to an engine air filter unit for a vehicle (1) that is designed to supply filtered air to an internal combustion engine of the vehicle (1). The engine air filter unit (10) comprises a main filter (14), a mounting base (15) to secure the engine air filter unit (10) on at least one body panel (7, 71, 72) of the vehicle, a pre-separator fluidically connected to the main filter. The main filter (14) is arranged on a side of the mounting base (15) and the pre-separator (18) is arranged on the opposite side of the mounting base (15). The pre-separator housing is at least partly formed by the mounting base (15) and an air duct (19) extends through the mounting base (15) to fluidically connect the pre-separator to the filtration chamber.

A method and extrusion die to form a laminar integral skin of a honeycomb structure is provided. The method includes extruding a ceramic precursor batch through a die with feedholes in entry side and slots in exit face of the die to form the honeycomb structure. In a region on the periphery of the die configured to form the cell matrix, a series of concentric slots around the matrix in the exit face of the die are configured to feed skin onto the matrix. Ring sections between concentric slots are angled away from the center and a mask is disposed on top of the periphery producing a channel for extruded skin to meet and bond to extruded matrix. Optionally, slots in the skin-forming ring sections enhance knitting between laminar skin layers.

An air filtration system comprising an extrusion frame with an associated grille proximal to an occupied space, the frame dimension for insertion within a drop ceiling or solid ceiling associated with either a plenum air space or directly to a return air duct associated with an air handler and conditioned supply air, a pleated filter positioned adjacent the grille so as to filter air flowing into the plenum air space from the occupied space, the pleated filter dimensioned for entrapping particles in the 1 to 3 micron size, an ultraviolet lamp for emitting UV-C light positioned adjacent the pleated air filter so as to substantially irradiate airborne particles that may pass through the pleated filter and, in particular to irradiate particles associated with microorganisms, including viruses, an electrical switch and associated electrical ballast for controlling operation of the electrical lamp and so as to ensure that the lamp is not energized when the air filtration system is being installed or service; and means for securing the extruded frame of the air filtration system to a drop ceiling or solid ceiling or wall.

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.

An air filtration system is coupled to an inlet of an enclosure of or to a piece of equipment. The air filtration system is coupled to the enclosure at the air inlet such that air entering the enclosure through the air inlet passes through the air filtration system. The air filtration system includes a frame assembly. The frame assembly includes an outer frame and a support mesh. The outer frame is coupled to the enclosure. The air filtration system includes a door assembly. The door assembly includes a door frame and a door support mesh. The door assembly is received by and mechanically coupled to the frame assembly. The air filtration system includes filter media positioned in an interior of the air filtration system defined by the frame assembly and the door assembly.

A filter device has a filter housing and a filter element arranged in the filter housing. The filter element at least partially encloses an inwardly positioned flow chamber. A purified medium can be discharged from the filter device through a flow socket provided with a wall that has an opening. A fastening flange is arranged at the wall of the flow socket adjacent to the opening, wherein a purging gas pipe of a purging device can be detachably fastened by the fastening flange to the flow socket. The opening in the wall of the flow socket receives the purging gas pipe.
