Low-profile air filtration module
First Claim
1. An air filtration module including a housing having an intake opening in the top of thereof, means in said housing adapted to support at least one filter unit, and blower means mounted in said housing and disposed to draw incoming air downward through said intake opening, and discharge said air into said housing through an exhaust opening, wherein the improvement comprises:
- a horizontal central panel secured in said housing, and separating the space defined by said housing into a conversion chamber above said panel and a distribution chamber below said panel and above the position of a filter unit established by said filter support means, said panel having a central opening providing communication between said chambers, said blower means being mounted in said conversion chamber beside said central opening; and
a duct plate mounted in said conversion chamber, and disposed to conduct exhaust from said blower means past said central opening to a position of discharge into said conversion chamber.

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.
