  • Patent number: 5141540
    Abstract: This low-profile filtration module has a blower partially occupying an equalization chamber above a standard filter unit. A diffuser plate is interposed between the filter and the equalization chamber, and has a plurality of openings elongated in a direction perpendicular to the planes of the filter pleats. The density of the openings is increased at the portions of the equalization chamber where the space for lateral air flow is decreased by the presence of the blower.

  • Patent number: 4976757
    Abstract: A filter plenum module has upper and lower peripheral frame extrusions providing vertically opposite and facing channels receiving side panels secured with fastenings traversing the inner flanges of the channels to engage the panels. Top closure panels are received on horizontal flanges of the top peripheral frame. Fastening and caulking are thus applied all from the inside, as the modules are constructed. Top panels are interconnected by reinforcing beams carried exclusively by the panels. These beams provide the principal support for the grid beams supporting the filter units. The peripheral beams also carry terminals that can be selectively placed to support the plenum assembly, according to the conditions available in the ceiling structure at the point of installation. Angle members are inserted in receptacle channels at the mitered corners of the peripheral beam extrusions for initial alignment.

  • Patent number: 4917713
    Abstract: This air filtration module has a rectangular housing separated vertically by a horizontal partition into upper and lower chambers communicating through a central opening in the partition panel. The lower chamber provides for distribution of air flow over the tops of filter units supported by the module below the distribution chamber. A blower is mounted at one end of the upper chamber, which discharges high-velocity air past the central opening in the partition panel, and into an opposite end of the upper chamber, where the velocity energy is converted to some degree to a lower velocity pressure energy. A ring surrounding the central opening above the partition panel stiffens the panel, and also provides support for an adjustable damper. The air intake through the module is drawn in by the blower through a preliminary filter in a frame horizontally opposite a bridge structure across the top of the module that supports the control devices associated with the blower.
