ABSTRACT:
A modular clean room load bearing structure having a negative air pressure plenum above the clean room ceiling to prevent the collection of dust and dirt above the ceiling. The vertical sidewall of the clean room is constructed of individual wall modules which are assembled together on site to construct the clean room. Each wall module serves as a return air duct for circulating air from the clean room upwardly through the wall module to the negative pressure plenum where the air is drawn out to a HVAC unit for conditioning the air. The conditioned air is returned to the clean room through a supply air duct system which includes HEPA filters in the clean room ceiling which filter the air immediately prior to the air being blown into the clean room. A support deck spans across the top of the sidewall and is formed by four foot wide structural panels spanning across the clean room. The deck supports the HVAC equipment above the deck while the clean room ceiling and HEPA filters are suspended from the deck. The total assembled clean room structure provides all of the required clean room features plus structural capabilities with a finished, aesthetically pleasing look.
