Abstract: A round filter element has an annular circumferentially extending pleated filter medium body to be flowed through by a fluid to be purified radially relative to a longitudinal axis of the filter medium body. A first end disk is arranged at a first end face of the filter medium body. A second end disk is arranged at a second end face of the filter medium body. The second end face is axially opposite the first end face. An outer or an inner contour of the first end disk is identically or at least substantially identically embodied to an outer or an inner contour of the filter medium body. An outer or an inner contour of the second end disk is identically or at least substantially identically embodied to the outer or the inner contour of the filter medium body. One of the first and second end disks is open.

Abstract: A filter element includes a media pack and a gasket member. The gasket member includes first and second gasket regions separated by a channel. The elements are usable in a dust collector having a dirty air inlet, a clean air outlet, and a tubesheet dividing between an unfiltered and a clean air volume. An element is removably mounted and sealed within the tube sheet. At least one projection angled relative to a plane of the tube sheet extends into the channel of the gasket member. A method of servicing a dust collector includes removing a first filter element from the tube sheet in the housing, and then sealing a second filter element against the tube sheet by orienting at least one projection extending from a plane of the tube sheet into a channel defined by a gasket member secured to the second filter element. An axial force is exerted to form a seal between the gasket member and the tube sheet.

Abstract: A filter assembly and a drying apparatus having the filter assembly are proposed. The filter assembly (180) may purify air introduced into the main body (100) of the drying apparatus. The filter assembly (180) may be protruded by a predetermined distance to a side surface of the main body (100) by the moving plate (190). The filter frame (182) protruded by the moving plate (190) may be removed from the moving plate (190) to perform maintenance of filters (184, 186, 188).

Abstract: Various example embodiments relate to a filtration system. The filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing comprises a first alignment portion disposed on the first housing end. The filtration system further comprises a filter element positioned within the central compartment of the housing. The filter element has a first filter end and a second filter end. The filter element comprises filter media and a second alignment portion disposed on the first filter end. The second alignment portion is complementary to the first alignment portion. The installation of the filter element within the housing causes the first alignment surface and the second alignment surface to align to provide for engagement of a radial seal between the filter element and the housing.

Abstract: Filter cartridges including tubular filter media having ovate cross-sections and filter systems using the ovate tubular filter cartridges are described herein. The inner perimeters of the ovate cross-sections of one or more of the filter cartridges may be asymmetric, i.e., the inner perimeters of the cross-sections of the tubular filter media in the filter cartridges may have no lines about which they are symmetric. The inner perimeters of the ovate cross-sections of the tubular filter media in one or more of the filter cartridges may have only one line of symmetry.

Abstract: A filter element for filtration and dehumidification of a gas has at least one filter medium body with an outflow side delimiting a clean-side flow chamber. A dehumidification unit is arranged downstream of the at least one filter medium body in a flow direction of the gas in the clean-side flow chamber. A carrier body accommodates the at least one filter medium body and the dehumidification unit. The dehumidification unit is connected flow-tightly to an outflow opening of the clean-side flow chamber. The dehumidification unit is arranged in the clean-side flow chamber at a spacing relative to the at least one filter medium body.

Abstract: A debris canister and filter assembly, which may be used in a vehicular vacuum cleaner, includes a debris canister having an inlet, an outlet, and a peripheral side wall. The peripheral side wall at least partially defines an interior space of the debris canister. A filter is disposed in the interior space of the debris canister, and includes filter media having a non-pleated portion and a pleated portion. The peripheral side wall forms a corner of the debris canister, and the filter media has a rounded-corner shaped to fit adjacent to the corner of the peripheral side wall.

Abstract: An air filter element for an air filter may include a first end plate and a second end plate spaced apart from each other in an axial direction and configured to bound the filter element in the axial direction. The first filter body may be arranged axially between the first and second end plates. A second filter body may be arranged axially between the first and second end plates. An intermediate plate may be arranged axially between the first and second filter bodies and have an intermediate plate area enclosed by an intermediate outer contour and a first end plate area enclosed by a first outer contour.

Abstract: Methods and systems are provided for regeneration of a particulate filter including a filter body having a filter paper looped along a plurality of rolling guides. At least one rolling guide may be a roller heater having a motor and a heater. Activation of the roller heater based on a pressure difference across the particulate filter regenerates the particulate filter during a regeneration phase and positions a regenerated section of the filter paper for trapping soot in a subsequent soot loading phase.
