Abstract

The disclosure relates to a filter cartridge for removing impurities from a stream of raw gas to be filtered, including a cylindrical filter element which is made of a filter material and in which a filter insert is inserted, an interior space being formed between the filter element and the filter insert, the filter material being designed to be cleaned when a stream of compressed air is applied against a flow direction of the stream of raw gas, a cap designed as a flow guiding device being provided for guiding the stream of compressed air, wherein the cap is arranged such that it projects beyond an axial length of the filter element in the axial direction. The disclosure further concerns a filter system for removing impurities from a stream of raw gas to be filtered. In addition, the disclosure relates to a method for cleaning such a filter cartridge.
