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.

Abstract: The present application relates to a filter cartridge for removing impurities from a dirty gas flow to be filtered, including 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, wherein 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 present application relates to a kit, a filter unit, and a method for cleaning the filter cartridge.

Abstract: The present invention generally relates to a backdraft damper having a flap valve, a dust collector having a backdraft damper and a method for preventing a pressure wave from propagating upstream of a dust collector. In one embodiment, a backdraft damper is provided that includes a body having a flap valve disposed therein. The flap valve includes a valve seat disposed in an interior volume of the body. The flap valve includes a blade movable between an open position and a closed position which prevents fluid flow between an inlet and an outlet of the body. The blade of the flap valve includes a core material sandwiched between a first plate and a second plate.
