ABSTRACT:
A ceiling system for clean rooms is disclosed employing two sets of framed filters, an upper set and a lower set arranged in checkerboard fashion. One set supports the other set and the supporting set is suspended from the overhead or ceiling of the room. A plenum of two height levels is formed. The upper set has depending skirts below the level of its filter medium. The lower set of framed filters include an outer lip or rim which seal the filter sets together at the depending skirts of the upper set. Auxiliary services such as lighting and sprinklers are fed from above the sets of framed filters via the depending skirts of the upper set. In one embodiment, the upper set of framed filters supports the lower set and in an alternate embodiment, the lower set of framed filters supports the upper set. Grid or T bar support systems are eliminated and nearly 100 % filtered laminar flow area is produced.
