  • Patent number: 6902603
    Abstract: An integrated air filtration unit includes a support structure for mounting a V-shaped filter bank to an air passage of an air handling system. The V-shaped filter bank may be moved from a working position in which the air is filtered to a service position in which a pair of filter pads in the filter bank can be accessed for service or replacement. The integrated air filter unit may include an ultraviolet irradiation system for destroying airborne micro-organisms trapped by the pair of filter pads.

  • Patent number: 6294004
    Abstract: Structures for V-bank electrostatic air filters are described. The V-bank air filters are assembled from two side panels, perforated top and bottom plates, a narrow end wall and an open wide end for the intake of air to be filtered. A pair of enclosure plates are pivotally mounted to the side panels in a parallel relationship to the respective top and bottom plates to form a pair of rectangular enclosures for respectively supporting electrostatic filter pads. The enclosure plates pivot open for removal and replacement of the filter pads. The side panels, top and bottom plates and rear wall are made from sheet metal blanks using cutting, bending and stamping processes. The enclosure plates are made from sheet metal blanks or welded wire structures. The advantage is that the structures are manufactured using simple automated processes and are quickly assembled without sub-assembly, thus time and labour are saved and costs are reduced.
