ABSTRACT:
A pre-assembled, self-contained clean room module having everything necessary for maintaining the cleanliness, temperature, humidity and pressurization required for the work space within the room. Because the module is factory built rather than built on site, precise quality control can be achieved and each module can be thoroughly tested before shipment. The module is provided with its own sealed base unit which permits it to be moved or relocated without having to be disassembled, and also insures that the module will have a completely sealed sump area beneath its floor. The module is also provided with its own self-contained air conditioning unit which has two independent air systems or paths whereby only a portion of the recirculating air need be conditioned.
