    摘要： A horizontal flat-fold, filtering face-piece respirator 10 that includes a harness 14 and a mask body 12 that has a front surface, a first perimeter 24a, and a longitudinal axis 34. A nose clip 30 is secured to the mask body 12 centrally and adjacent to the first perimeter 24a of the mask body 12. An indicia 32 that is visible on the front surface of the mask body 12 in a vicinity of the nose clip 30 is provided to highlight a longitudinal axis of symmetry of the nose clip. The use of such an indicia, visible from the mask body front surface, enables a user to readily identify where the nose clip may be bent to prepare it for donning by the wearer.

    摘要： A flat-fold filtering face piece respirator 10 that comprises a mask body 12 that has a transversely-extending line of demarcation 22 and a longitudinal axis 34. First and second weld patterns 32a, 32b are disposed above and not traversing the line of demarcation on each side of the longitudinal axis 34, respectively. Third and fourth weld patterns 32c, 32d are disposed below and not crossing the line of demarcation 22 on each side of the longitudinal axis 34, respectively. Each of the first, second, third, and fourth weld patterns 32a-32d is a two-dimensional enclosed pattern. This combined weld patterns can provide a mask body that exhibits crush resistance without the need for additional or heavier layers, which may cause higher pressure drops across the filtering structure.

    摘要： The invention is related to a framed filter media comprising a pleated filter media having a fluid inlet face and a fluid outlet face with peripheral sidewalls. The peripheral sidewalls of the pleated filter are attached to the frame generally by an adhesive. The frame is preferably a flexible strip frame formed into three or more (up to an infinite number if the sidewall sections(s) is formed into a circular filter frame) sidewall sections each having a substantially flat sidewall and at least two projecting filter retaining tabs which form a flange on a first face of the sidewall section for containing the filter along its peripheral sidewalls and any adhesive. A cross brace is also inserted within the filter retaining tabs which fits into at least one pleat of the framed pleated filter media. The cross brace fits into the space formed by the pleated filter media but is not in continuous contact with the filter media forming the pleat. The cross brace can be flexible and has end keys or projections for insertion into the filter frame flanges and attachment to the sidewall sections and/or the flange. In a particular embodiment, the cross brace has a continuous non-linear profile with an internal profiled groove with a mating surface, for insertion and locking of removable end keys or other items, such as handles and labels, which removable items have a profile that mates with, or locks the mating surface of the profiled groove.

    摘要： The method of forming pleated filter media includes providing a generally planar web of filter material, folding the web to form a pleated web having a plurality of fold lines, arranging the plurality of pleats in a first spaced configuration defined by a first distance between adjacent pleat tips, applying a continuous strand of adhesive to the web, and adjusting the arrangement of the plurality of pleats into a second spaced configuration defined by a second distance between adjacent pleat tips. The web has a front face and a rear face. Each fold line is intermediate oppositely sloping first and second wall surfaces. The plurality of fold lines form a plurality of pleats having a first plurality of pleat tips and a second plurality of pleat valleys. The second distance is different from the first distance.

    摘要： There is provided in a standard ceiling system, having suspension rails or elements a movable air delivery diffuser resting on the suspension elements and a filter panel inserted into and retained between the suspension elements and the air delivery diffuser. The filter panel has a filter frame and an attached filter designed to be inserted into and retained on the suspension elements of the suspension ceiling. The filter frame has an inner face and an outer face with a filter media retained in the filter frame. The outer edges of the filter media are located and retained adjacent the filter frame inner face. The filter frame outer face has a flexible perimeter flange projecting outwardly from an uppermost portion of the filter frame outer face. This flexible perimeter flange can bend inwardly so as to be substantially flush with said frame outer face and can then flex back outward to engage the suspension elements. The flexible flange preferably can also extend outward so that it is in a direction substantially perpendicular to the filter frame outer face, so that it can be retained between, and frictionally engage, the suspension elements and an outermost edge of the air delivery diffuser or plenum otherwise resting on the suspension elements.
