Selective etching techniques are used to manufacture a basic filtration element, which can then be used as a basis for constructing various devices for different applications. In this process, sheets of etchable material are etched from one or both sides of that sheet to form channels in a premasked pattern, which controls the minimum opening of the filtration element. The desired channel opening is only limited by the capability of the photochemical etching system being used. Alternatively, a filter element may be made by rolling or extruding a first sheet to form a plurality of recessed areas bordered by lands, selectively etching or punching through the recessed pattern areas, and bonding a second sheet having a plurality of etched or punched through areas to the first sheet, and, aligning the etched through areas to the second sheet with the recessed areas of the first sheet.

LOW PROFILE FRAME FOR A FILTER INCORPORATING A NEGATIVE PRESSURE CHECK MECHANISM

Номер: US20130298512A1
Автор: Symons Daniel Charles
Принадлежит: Scott Technologies, Inc.

A low-profile filter frame is disclosed for maintaining an open filter plenum configuration during normal operation, and for enabling quick and reliable negative pressure testing. The frame has upper and lower halves. A breathing tube in the lower half connects to a respirator port. The upper and lower halves snap together to maintain the structure in an assembled configuration. The halves also include features that bias the halves apart when the device is in the assembled configuration, thereby maintaining the breathing tube open. To perform a fit test, a force is applied to an outer surface of the upper half, which moves the halves together, in opposition to the bias, so that the upper half seals against the breathing tube. The frame can be provide in as a single-piece, with a living hinge connecting upper and lower halves, or the upper and lower halves can be separate pieces. 1. A single piece filter frame structure comprising:a frame having upper and lower halves and a living hinge disposed therebetween, the upper and lower halves configured to cooperate with a low profile particulate filter; the upper and lower halves further comprising a snap joint for engaging the upper half to the lower half when the device is folded at the living hinge to maintain the structure in an assembled configuration;wherein the frame has an open plenum configuration in which a filter plenum is held in an open position, and a negative pressure check configuration in which a portion of the upper half seals against a portion of the lower half to facilitate seal and leak tightness of a facepiece associated with the filter structure.2. The single piece filter frame structure of claim 1 , the lower half including a breathing tube for connecting to an associated port of a respirator; the lower half further including a fulcrum bar to engage a cantilever beam of the upper half to bias the upper and lower halves apart when the device is in the assembled configuration.3.

A method of making a multilayer filter and the multilayer filter made by the method. The method includes generally two steps. The first step is to coat a layer of nanofibers on a single side or both sides of a substrate medium to obtain a composite filter medium, and the second step is to fold the composite filter medium in a serpentine fashion to form a multilayer filter. The second step may alternatively be accomplished by stacking up a number of sheets of the composite filter medium to form a multilayer filter having a structure of two layers of nanofibers being sandwiched between two layers of said substrate medium. The resulting multilayer filter produced by either method contains at least one structural unit which has two layers of nanofibers being sandwiched between two layers of the substrate medium.

COALESCING FILTER MEDIA

Номер: US20210001263A1
Автор: Boesner Jens-Peter
Принадлежит: Hollingsworth & Vose Company

Filter media, filter elements, and methods for filtering an gas stream are described herein. In some embodiments, the filter media may comprise a fiber web comprising a plurality of fibers and having a particular oil repellency level. For instance, in certain embodiments, the surface chemistry of the fiber web may be tailored to impart a particular surface energy density that matches the surface energy density of the fluid (e.g., an oil, a lubricant, and/or a cooling agent) being removed from the gas stream. In some embodiments, the fiber web may be wrapped around a core. For example, the fiber web may be wrapped around the core such that it forms two or more layers around the core. In some cases, the fiber web may be perforated. In certain embodiments, an gas stream comprising a fluid (e.g., an oil, a lubricant, and/or a cooling agent) may be passed through the fiber web, filter media, and/or filter element such that at least a portion of the fluid coalesces on the fiber web. Fiber webs, filter media, and/or filter elements as described herein may be particularly well-suited for applications that involve filtering gas streams containing oil, lubricants, and/or cooling agents (e.g., gas streams generated by a compressor) though the media may also be used in other applications. Advantageously, the fiber webs, filter media, and/or filter elements described herein may significantly reduce or prevent fouling of the filter caused by oil or other liquids. 1passing the gas stream including the oil, lubricant, and/or cooling agent through a filter element, wherein the filter element comprises a fiber web wrapped around a core such that at least two layers of the fiber web are formed, the fiber web comprising:a plurality of fibers having an average fiber diameter of at least 0.01 microns and less than or equal to 50 microns;{'sup': 2', '2, 'a basis weight of at least 1 g/mand less than or equal to 270 g/m; and'}a thickness of at least 0.01 mm and less than or equal to 5.0 mm ...
