A cassette filter assembly for removing particles from an air stream, in particular from a gas stream entering a gas turbine, has an upstream end and a downstream end and comprises a header frame to which a filter media is fitted and which has an inlet guide on said mounting face, the inlet guide having a plurality of openings, each opening being defined by a pair of lofted short sides and a pair of lofted long sides.

Filter assembly with curved inlet guide

A V-panel filter apparatus and method of construction are provided. The method includes flowing curable potting material into a recess portion of an end cap, positioning first end edge surfaces of first and second filter panels into the contained potting material, and curing the potting material with the first and second filter panels positioned to diverge away from the end cap to define a V-shaped configuration. The method may include flowing curable potting material into a recess portion of a first side plate, positioning edge surfaces of the first and second filter panels into the contained potting material, and curing the potting material. Such steps may be repeated in relation to a second side plate and a header member. By utilizing a pot-and-place sealing methodology, improved seal interfaces are realized. Stability and construction advantages may be provided by snap-fit features of the header member and first and second side plates.

V-panel filters

An article useful as an architectural fabric having (a) a plurality of segments of fabric having a first surface and a second surface made of polytetrafluoroethylene fibers; and (b) a fluoropolymer coating disposed on at least the first surface of the fabric, and (c) at least one seam formed by an overlap of two of said segments, said seam having a seam warp strip tensile strength that is substantially equal to said nominal warp strip tensile strength at room temperature.

High seam strength architectural fabric

An article useful as an architectural fabric consisting of (a) a layer of fabric having a first surface and a second surface made of expanded polytetrafluoroethylene fibers that are densified or contain a filler or both; and (b) a fluoropolymer coating disposed on at least the first surface of the fabric.

Architectural fabric

An article useful as an architectural fabric consisting of (a) a layer of fabric having a first surface and a second surface made of polytetrafluoroethylene fibers; and (b) a fluoropolymer coating disposed on at least the first surface of the fabric.

An article having (a) a layer of fabric having a first surface and a second surface made of polytetrafluoroethylene fibers; and (b) a first composite comprising (i) a porous PTFE film having interconnected passages and pathways and (ii) a fluoropolymer adhesive, wherein said fluoropolymer adhesive is at least partially contained in said passages and pathways of said PTFE film, said first composite disposed adjacent to said first surface of said fabric, wherein the article passes a Newark Flex test after 10,000 cycles. In another embodiment, the invention includes a second composite comprising (i) a porous PTFE film having interconnected passages and pathways and (ii) a fluoropolymer adhesive, wherein said fluoropolymer adhesive is at least partially contained in said passages and pathways of said PTFE film, said second composite disposed adjacent to said second surface of said fabric. The article of the present invention is preferably waterproof, fire retardant, and flexible. It is also preferably an architectural fabric for retractable, temporary, or permanent structures and is adapted to be joined to itself by heat welding.
