Abstract
A modular clean room is disclosed for maintaining an environment free of particulate contaminants comprising prefabricated modules which are detachably connected to form a self supporting structure having interior space through which filtered air is flowed. The modules include an air circulating module which supplies a flow of filtered air, a duct module in the form of a service corridor which provides a flow path for the recirculation of air within the interior space, and a floor module which provides a raised floor surface through which air can flow, to an underfloor space communicating with the duct module to recirculate filtered air within the room.
Claims4
A clean room made of prefabricated modules comprising:
- a pair of duct modules spaced from each other to define a work space between them, each module having a tubular box-like frame outlining a pair of spaced side walls, a pair of end walls, and a ceiling, and panels attached to the frame to define a self-supported, closed service corridor, and including a door in one of the panels for entering the corridor, at least one of said duct modules having an air inlet at a lower level and an air exit at an upper level, the air inlet being formed in the panel adjoining the work space;
- an air circulating module having a box-like, tubular frame extending over the space between the duct modules and supported overhead by the duct modules, panels attached to said air circulating frame and enclosing the top and side walls of the air circulating module, the air circulating module further including a blower assembly mounted to said air circulating frame, positioned adjacent to and in communication with said air exit, said air circulating module further including a filter assembly positioned in the lower portion of said air circulating frame and extending over said work space so that air from the blower assembly is directed inwardly between the upper panel of the air circulating module and downwardly through the filter assembly;
- and
- wall panels cooperating with said modules to complete the enclosure of the interior work space with said air inlets of the duct modules being open to said space so that air flowing from the filter assembly will pass through said space in a descending manner to said duct module air inlet, wherein the air is directed upwrdly in said duct modules through said air exit leading to the blower assembly.
