Abstract: The air filter systems described herein include one or more pulse collectors and pulse generators aligned along pulse axes. The pulse generators and filter elements may be arranged along a pulse distance as measured from a pulse outlet to a filter element opening. The pulse collectors and the filter elements may have openings with a relationship between them within parameters described herein. The pulse collectors may have a relationship between their hydraulic diameter and their length within parameters described herein. The pulse collectors may include a filter section and a pulse section that meet at a junction along a length of the pulse collector. The pulse sections may have a hydraulic diameter that increases when moving from the junction to the tube sheet opening of the pulse section. The filter sections may have a hydraulic diameter that remains constant when moving from the junction to the filter end opening of the filter section. Filter elements/cartridges used in the air filter systems may have filter media shaped or formed into ovate cross-sections

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.
