ABSTRACT:
A filter device for media, such as air and liquids, has a filter cartridge which has an inflow surface and a flow-off surface, a disk-shaped adaptor located at one end of the filter cartridge, at least one first orifice for the inflowing unfiltered medium, at least one second orifice for the flowing-off filtered medium, a filter bowl which has a side wall and a bottom region, and a sealing device between the adaptor and the free end region of the side wall. A media-proof hose is connected in a sealed manner by means of one end region to a face of the adaptor which is at least adjacent to the edge region of the side wall of the filter bowl. The hose, at least over part of its length, receives the filter cartridge. The second end region of the hose is closed at least during the operation of the filter device. The hose material has such strength that, when detached from the filter bowl and filter cartridge, it does not tear despite the filtrate and medium contained in the hose.
