摘要： A high efficiency particulate air filter (16) is disclosed which has a channel formed in the front peripheral surface thereof, with the channel being substantially filled with a sealant (30) which comprises an essentially non-volatile and non-hardening gum-like material. The physical properties of the sealant render the sealant able to effect sealing engagement with a mating flange (45) mounted in the filter housing, and also permit the flange to be withdrawn from the sealant without an appreciable amount of the sealant adhering to the flange, to thereby avoid the build up of potentially contaminated sealant on the flange when the filter is changed. A method of fabricating the filter is also disclosed, which results in the sealant forming a substantially uniform and continuous closed strip which is characterized by the absence of a butt end joint.

摘要： @§ An air flow control apparatus is disclosed which is characterized by essentially zero leakage in its closed position, and by minimal air resistance in its open position. The apparatus includes a housing (12) having an interior framework which defines a plurality of troughs (21) of V-shaped cross section, and with each side of each trough including an opening (34). A closure is associated with each trough, which includes a pair of pivotally mounted plates (39, 40) which are movable between a spread apart position covering and closing the openings in the trough, and a collapsed position wherein the plates are substantially aligned with each other and spaced from the associated openings to permit free air flow therethrough. A continuous upstanding peripheral flange (28, 30, 31, 32) surrounds each opening, and a resilient pad (44) is mounted on each plate of each closure so that the resilient pad mates with the outer edge of the flange when the closure is moved to the spread apart position, and so that the outer edge presses into the resilient pad to effect an air tight seal. The axis (41) of the pivotal plates is adjustable to permit the pressure between the plates and outer edge of the flanges to be uniform about the periphery of each opening.

摘要： A method and apparatus for the leak testing of one or more filters, which requires minimum space, and which comprises a housing (12) adapted to sealably mount the filters (30), supply pipes (40, 41) for introducing DOP particles within the housing and immediately upstream of each of the filters, and a restriction member (54) mounted in the housing upstream of each filter and downstream of the point at which the DOP is introduced. The member (54) may be selectively positioned to assume an operative position transverse to the airstream wherein it acts to condense and mix the airstream and DOP and then disperse the mixture over the full frontal area of the adjacent filter, or a non-operative position wherein the member is substantially withdrawn from the airstream. A sampling device (70) is also mounted downstream of each filter for monitoring the airstream to detect DOP particles, and thereby permit a determination as to whether any of the particles are leaking through or around the filter.

摘要： A high efficiency particulate air filter (20) is provided which is of lightweight and readily disposable after use. Furthermore, this filter may be fabricated in a basic or universal form, which permits it to be utilized to form any one of a number of possible specific mounting configurations by the placement of one or more specifically designed headers about its outer periphery. The filter (20) comprises a sheet of filtering media folded upon itself in accordion fashion to form a filter pack (22), and a relatively thin and lightweight peripheral frame (32) surrounding and supporting the pack. The frame is composed of a relatively hard, crust-like, air impermeable molded material which is self-bonded and sealed to the filter pack effectively to preclude the leakage of air therebetween. Internal integral reinforcing ribs are formed in the material of the frame along at least two opposite sides of the pack, to provide sufficient strength to permit the filter to be mounted against a pressure seal or the like.

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 method and apparatus for the leak testing of one or more filters, and comprising a housing adapted to sealably mount the filters, means for introducing DOP particles within the housing and immediately upstream of each of the filters, and means for imparting a like electrical charge to the particles such that the particles repel each other and rapidly disperse within the airstream so as to be substantially uniformly dispersed upon reaching the face of each filter. A collecting surface may be disposed downstream of the filters for detecting any of the charged particles to thereby permit a determination as to whether the filters are leaking. Alternatively, a collapsible panel system may be positioned immediately downstream of the filter to condense and impart turbulence to the airstream to thereby permit a sample to be withdrawn for analysis from a point closely adjacent the filter.

摘要： 1477570 Air filters FLANDERS FILTERS INC 28 Nov 1975 [5 Dec 1974] 49101/75 Heading B1T [Also in Divisions F2 and F4] An air filter element 49 capable of removing sub-micron sized particles has combined therewith a rectangular frame member 47 in which it is sealably disposed, the opening through the frame being closed, suitably on the downstream side of the filter element, by valve means 60 comprising a pair of rectangular plates of a size conforming to the outline of the frame and each having numerous apertures 56 therethrough, the apertures being distributed over the entire surface of the plates and corresponding in position and number on each plate, the plates being mounted for sliding movement relative each other so that the apertures in each may be brought into alignment to open the valve or taken out of alignment to close the valve and a film of non-evaporating viscous fluid, e.g. petrolatum or silicone grease, being interposed between opposing faces of the plates to prevent lateral flow of air between the plates. The filter elements may comprise pleated sheets of glass, ceramic or cellulose-asbestos. The frames 47 may be wood or pressed chipboard. A plurality of the filter element/frame/valve units may be mounted in parallel in channel members 41, the channels being partially filled with a fluid to form a seal. A clean room is described comprising a false ceiling formed from a bank of the filter element/valve units mounted in the channel members 41, the channel members being sealed to the room walls at the periphery of the filter bank. The space above the false ceiling provides an inlet plenum for gas to be filtered fed in via a blower from a bank of coarse pre-filters mounted behind a wall of the room and filtering air circulating from grills in the room floor. The valve means for each filter element are arranged to be individually operatable from within the room.

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.
