摘要： A washable cloth vacuum cleaner filter bag for use on wet/dry vacuum cleaners and in central vacuum cleaner systems includes a first opening for receiving vacuumed debris, means for attaching the first opening to the inlet of the vacuum cleaner or system, and a second opening, which is reversably sealable, for removing the vacuumed debris from the bag. In combination with the bag, the vacuum cleaner or system may be successfully used to suction up fine particulate debris, including gypsum dust and MDF dust. For a preferred embodiment of the new vacuum cleaner filter bag, the bag, which is of generally rectangular shape, is fabricated from a tight weave, synthetic-fiber cloth having a warp of about 160 threads per inch and a weft of about 68 threads per inch. A variety of fastener types may be employed for the reversably sealable second opening. The second opening incorporates a cuff on one side of the opening which is turned inside out to fold over the edge of the other side of the bag.

摘要： A mounting collar is for supporting a vacuum cleaner filter bag in a mounted condition over a vacuum cleaner fill tube. The fill tube has a cylindrical outer surface. A panel of the mounting collar is configured to be attached to the filter bag. The panel has a first inner edge defining a first opening for receiving the fill tube. An elastomeric diaphragm of the collar extends across the first opening. The diaphragm has a second inner edge defining a second opening. The second inner edge is configured to be elastically stretched circumferentially about the fill tube and to be in contact with the cylindrical outer surface about the entire circumference of the cylindrical outer surface when the first opening receives the fill tube. A lobe of the diaphragm is defined by the second inner edge and a baseline. The baseline extends from a first point on the second inner edge to a second point on the second inner edge and is located entirely on the diaphragm.

摘要： A filter element is includes a cylindrical media pack defining a central open volume and a longitudinal axis; a first end cap having a central aperture in flow communication with the central open volume; and a second, closed end cap having a central region closing an end of the media pack central, open volume. The closed end cap includes a projection extending axially outwardly therefrom and positioned at a location intersected by the longitudinal axis. An end cover for an air cleaner includes an inner side including a central projection thereon. Preferably, the central projection comprises a wall that includes an outer perimeter defining a regular polyhedron having at least five sides. An air cleaner comprises a cylindrical filter element having a first open end cap, a second closed end cap, and a cylindrical media pack extending therebetween. The first end cap defines an internal radial seal region. The second, closed end cap has a central region including a circular recessed portion. The air cleaner also includes an end cover. The end cover includes an inner side including a central projection thereon. The central projection is sized and shaped to matably engage the recessed portion of the second closed end cap, when the filter element is operably installed in the end cover. Methods for installing a filter element in an air cleaner preferably will use constructions as described herein.

摘要： A ring filter comprising a star-shaped folded filtering material and a closure on both front sides thereof in the form of a closed end disc. This closure has a plate-shaped insert forming the central area of the closure and located radially inside the filtering material. The insert is made of a different material from that of the rest of the closure. The invention aims at providing a ring filter than can be rationally produced and that is more resistant and durable. To this end, the ring filter has a radially permeable tubular frame that extends approximately along the entire axial length of the ring filter that borders radially inward on the filtering material; and wherein the plate-shaped insert is connected to the tubular frame and wherein the material of the closure is a foamed plastic.
