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.
