A filter arrangement made up of an accordion fold pack which is sealingly arranged in a housing. The housing is deep drawn in one piece from a polymeric material sheet. A limit stop is punched out of the base of the housing. A seal surrounds the accordion fold pack and seals against the housing.

Filter arrangement and a method for its manufacture

A filter cartridge has a frame made of tough material, which sealingly surrounds an accordion fold pack on its circumferential side. The frame is made of assemblable, plate-shaped frame elements and has, on the circumferential side along the lower and/or upper edge of the frame, a tongue, the tongue being insertable in a latticed holder having a U-shaped profile. A viscous joining compound is used to affix the tongue in place. The tongue is formed by strip-shaped tongue elements, each tongue element being joined to a frame element, wherein the adjacent ends of the tongue elements are sealingly fastened to each other by connecting corner pieces.
