Abstract
The invention relates to a filter cartridge for removing impurities from a dirty gas flow to be filtered. The filter cartridge includes a cylindrical filter element made from filter material, a filter insert inserted in the filter element, an inner space formed between the filter element and the filter insert, with the filter material being designed for being cleaned when a compressed air flow is applied against a flow direction of the dirty gas flow, and a base body of a flow guiding device having a surface designed for guiding the compressed air flow. The base body has a distal end zone which is prepared for being completed by an end piece separate from the filter cartridge and mountable to an external housing for flow guiding the compressed air flow. Further, the invention relates to a centering device, a filter unit, a method for assembling and a method for cleaning said filter cartridge.
