ABSTRACT:
A clean room having provision for supplying filtered air vertically therethrough under substantially laminar flow conditions is disclosed, and which 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. The interconnected members of the latticework include a plurality of parallel, laterally spaced apart lengthwise members, and a plurality of cross members extending laterally between the lengthwise members, and with the ends of the cross members abutting an intermediate length of the lengthwise members. In one embodiment, each of the members of the latticework includes an integral, upwardly extending post, which is adapted to be engaged by a retainer for interconnecting the members, and also by a support bracket for supporting the latticework from an overhead ceiling. The members preferably have 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. Also, a sealant is disposed between the filters and supporting latticework, which comprises an essentially non-volatile and non-hardening polysiloxane gum.
