摘要： @ An air flow control apparatus is disclosed which is characterized by an essentially zero leakage rate in its closed position, and by minimal air resistance in its open position. The apparatus includes an orifice panel (58) which defines a plurality of troughs (59) of V-shaped cross section, with at least one elongate opening (62, 63) disposed in each trough. A closure (65) is associated with each trough (59), and includes a pair of pivotally mounted plates (67, 68) which are movable between a spread apart position wherein the plates (67, 68) cover and close the openings (62, 63) in the trough (59), and a collapsed position wherein the plates (67, 68) are contiguous to each other and spaced from the associated openings (62, 63) to permit free air flow therethrough. In one embodiment, the apparatus comprises a damper assembly (54) composed of the orifice panel (58) and closures (65), and which is removably mounted in a duct (20) so as to facilitate its repair and replacement.

摘要： 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.

摘要： A novel filter testing apparatus and method are provided wherein a challenge aerosol (CA) or the like is introduced upstream of the filter (16), and the downstream face of the filter (16) is scanned with an air sampling probe (30) to detect for the presence of leaking aerosol. The novel apparatus comprises a generally rectangular frame (22), and an air sampling probe (30) which is mounted to the frame (22) so as to be movable in a predetermined pattern wherein the entire face of an adjacent filter (16) is scanned. The assembly (20) may be removably mounted in a filter housing (10) immediately downstream of the filter (16), or mounted on a framework (88) downstream of a bank (86) of several filters (16). In the latter instance, means are provided for sequentially indexing the assembly (20) to a position in alignment with each filter (16), and an upstream aerosol dispersion assembly (112) is also provided which is correspondingly indexed across the filter bank (86). Means (79, 80) are also provided for continuously plotting the rate of leaking challenge aerosol on a moving sheet of paper (81), to thereby permit the magnitude of a leak and its location on the face of the filter (16) to be readily determined.
