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to effect sealing engagement with a mating flange (45) mounted in the filter housing, and also permit the flange to be withdrawn from the sealant without an appreciable amount of the sealant adhering to the flange, to thereby avoid the build up of potentially contaminated sealant on the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 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 high efficiency particulate air filter (22) comprises a frame surrounding and seal ably supporting the filter pack, with the frame composed of four separate side panels (34) which are rigidly inter connected at their abutting ends by means of corner plates (54). The corner plates (54) are formed by two flanges (55, 56) disposed at right angles to each other, and these flanges are closely received within slots formed on the outer faces (41) of the side panels. The corner plates preferably extend across the entire width of the side panels (34) to impart substantial rigidity to the frame, and a sealing material (58) is disposed in a recess which extends along the bight of the corner plates (54) to provide a continuous seal along the abutting ends of the side panels (34).

摘要： A method and apparatus for the leak testing of filters (30) arranged in series in a housing, comprises supply pipes (40, 41) for introducing DOP particles within the housing and immediately upstream of each filter, and a hinged restriction member (54a, 54b) mounted in the housing upstream of each filter and downstream of the location at which the DOP is introduced for mixing the airstream and DOP and then dispersing the mixture over the full frontal area of the adjacent filter. A sampling device (70b, 70c) is mounted downstream of each filter for monitoring the airstream to detect DOP particles and thereby permit a determination as to whether any particles are leaking through or around the filter. The restriction member (54b) disposed between the filters serves the dual purpose of mixing the airstream and any leaking particles, during testing of the upstream filter, preparatory to monitoring of the airstream by the sampling device (70b), as well as mixing the airstream and the particles introduced by the adjacent upstream supply pipes (40, 41), preparatory to dispersing the mixture over the full frontal area of the downstream filter, during testing of the latter.

摘要： A filter bank supporting latticework comprises a plurality of connectors (10,28,29) each of which has two, three or four extensions (12) radiating from a common central location. Each of the extensions (12) has a U-shaped cross sectional configuration so as to define a bottom wall and two opposite side walls. A threaded coupling member (18) is disposed at the central location of each four-extension connectors (10) for securing the connector to a supporting tie rod (19), and a protruberance (20) is disposed within each U-shaped extension at a predetermined distance from the central location. Adjacent connectors are adapted to be joined by an interconnecting channel (31,32) of predetermined length, with the ends of the channel being positioned within aligned extensions (12) of adjacent connectors, and with the ends of the channels (31,32) abutting the respective protruberances (20). A supporting latticework is thereby constructed which defines a plurality of rectangular open areas, and the length and width dimensions of each open area is automatically established. Each extension (12) of each connector further includes a transverse groove (22) extending about the inside surface thereof, and an aperture (24) extending through one of the walls and communicating with the groove. A caulking material may be forced through the aperture (24) after the interconnecting channel (31.32) is secured in the extension (12), and so that the caulking material is able to flow along the groove and form a seal between the extension and channel.
