Filter element has filter material surrounding riser pipe having recess at one end for filter material

摘要

A filter element has a riser pipe (10) and a filter material (12) surrounding the pipe. The pipe has a recess (20) at one end for the filter material so that a separating join between the filter material as one component group and the riser pipe as the other component group is produced which allows the contaminated filter material to be exchanged. Preferred Features: The recess is a ring-like groove (26) into which the filter material can be placed. The recess is provided with a screw piece (38) having a screw connection (40) with the housing parts (34).
