ABSTRACT:
A clean room having provision for supplying filtered air vertically therethrough under substantially laminar flow conditions is disclosed, and which is characterized by the substantial absence of migration of dust or dirt particles laterally through the room. The clean room includes a filter bank comprising a supporting latticework composed of a plurality of interconnected members which define rectangular open areas, and a plurality of high efficiency air filters positioned on the supporting latticework. Each of the members of the latticework has a generally V-shaped outline in cross section with the angular extent of the V-shaped outline being adapted to provide a substantially laminar flow therealong, and so as eliminate any substantial turbulence below the members of the latticework. Such turbulence has been found to entrain dust or dirt particles and move the same laterally through the room, and the elimination of such turbulence effectively eliminates the lateral migration problem. A sealant is disposed between the filters and supporting latticework, which comprises an essentially non-volatile and non-hardening polysiloxane gum.
