    摘要： A filter element comprises a pleated metal fiber fleece which is pleated according to pleating lines, providing an edge with pleat openings to be closed to make gas flowing through the metal fiber fleece. The filter element comprises at least two flanks, each of these flanks comprises a ceramic plate. The metal fiber fleece is mounted between the ceramic plates of both flanks, while flanks exercising a clamping force on the edges of the metal fiber fleece in a direction essentially parallel to the pleating lines, meanwhile closing the pleat openings.

    摘要： A method for operating a filter assembly having a filter medium includes applying a constant or nearly constant static DC potential to dust entering the filter assembly and the filter medium, passing dust-laden gas through the filter medium in a first direction through the filter assembly while the filter medium is statically charged with the DC potential, measuring pressure drop through the filter assembly, and, in response to the pressure drop meeting a preset limit, reversing the polarity of the DC potential to thereby allow dust particles on the filter medium to drop off the filter medium.

    摘要： A filter apparatus for mounting over an opening at an end of a forced air system duct has a filter frame with sidewalls between open front and back ends and a channel which opens inwardly of the sidewalls. At the front end is a sheet of preferably self charging electrostatic washable filter material behind a grill, both of which are peripherally disposed within the channel and are sized and sufficiently flexible so as to be removably insertable into the channel. A second sheet of a second filter material, preferably including activated charcoal, may be disposed in the channel behind the first sheet of filter material. The filter material may be made of a woven polypropylene and the sheet may have heat sealed finished edges. A wall mount having a support frame for mounting on a wall around the opening which extends through the wall is sized and operable to support the filter frame. The support frame may be mounted to a wall. A securing lock may be used to lock the filter frame in place within the support frame and may have a pin slideably and tightly disposed through aligned apertures in the filter and support frames.
