ABSTRACT:
A clean room is disclosed which has a capability of being divided into separate work areas of predetermined size, and with the separate work areas being effectively isolated from each other to prevent cross contamination. The clean room comprises a filter bank composed of a supporting latticework and a plurality of filters, with the latticework being supported by tie rods which extend through the latticework. A plurality of wall panels are supported below the latticework, and are attached directy to the tie rods so that the weight of the wall panels is not borne directly by the tie rods and by the latticework. Also, the latticework and wall panels are effectively isolated from external vibrations, by means of a flexible sealing strip between the periphery of the latticework and the bounding side walls of the clean room, and by the fact that the wall panels are free of any connection with the floor of the clean room.
