FILTER ARRANGEMENT, IN PARTICULAR AIR FILTER ARRANGEMENT

摘要

Within a housing with an untreated room entrance and a clean room exit, a filter insert is arranged at the clean room exit in such a manner that the interior of the filter insert forms a clean room and the space remaining in the housing outside the filter insert forms an untreated room. A housing interior lining is arranged on the filter insert in the vicinity of the clean room exit in order to prevent dirt from penetrating the clean room exit during changing of the filter insert.
