Abstract

A clean room having provision for supplying filtered air vertically therethrough under substantially laminar flow conditions includes a filter bank (16) comprising a supporting latticework (30) composed of a plurality of interconnected members which define rectangular open areas, and a plurality of high efficiency air filters (74) positioned on the supporting latticework. Each of the members (34,36) 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 (34,36) 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 lateral migration of dust or dirt particles.
