  • Patent number: 8182568
    Abstract: The two-stage air filter is formed of a nonwoven glass fiber first or inlet filter element and a second or outlet filter element formed of nonwoven fiber. The outlet filter element is preferably formed of either polyester material, or a blend of polyester and cotton fiber material. The first or inlet filter element is coarser than the second or outlet filter element, with the first element serving to capture larger particles while allowing smaller particles to pass therethrough to be captured by the finer second filter element. The two filter elements have a continuous and unbroken, homogeneous interface therebetween, with the attachment of the two filter elements with one another being solely at their mutual peripheries by a peripheral frame. Additional air freshening and cleaning, deodorizing, odor neutralizing, scent applying, fungicidal, bactericidal, and/or germicidal chemicals or materials may be applied to either or both filter elements.

    Abstract: Collection apparatus are installed in a horizontal separator vessel to aid conventional coalescing media to remove mist and droplets from a gas flow, typically downstream from a compressor. The collection apparatus have filaments which act to wick the coalesced droplets either from the conventional coalescing media or from the sides of the vessel toward an annular channel which collects the droplets and assists in delivering the droplets, by gravity, to the bottom of horizontal vessel where they are carried to a collection area. Use of the collection apparatus permits a reduction in the size of the separator vessel and further permits vapor load factors of up to about 10 times that in a conventionally designed separator vessel.

  • Patent number: 7585358
    Abstract: A recirculation filter includes a first layer and a second layer. The first layer has a first side and a second side and is configured to trap particles that are of a first size. The second layer has a first portion adjacent to the first side of the first layer and a second portion adjacent the second side of the first layer. The second layer is configured to trap particles that are of a second size. The second size of particles trapped by the second layer is greater than the first size of particles trapped by the first layer.

  • Publication number: 20090211214
    Abstract: The invention relates to a filter plate for a particulate filter which serves to separate particulates out of an exhaust gas flow of an internal combustion engine. A filter plate for a particulate filter which serves to separate particulates out of an exhaust gas flow of an internal combustion engine is proposed, which filter plate is composed of a substrate material, which is permeable to gas and is coated with a sintered metal powder, and has a surface region which extends substantially in a plane. It is provided according to the invention that the surface region (2) is provided with alternating linear depressions (3) and elevations (4), with a section (2a) of the planar surface region (2) remaining at least between two successive depressions (3) or elevations (4). The filter plate is suitable for the construction of a particulate filter which serves to separate particulates out of an exhaust gas flow of an internal combustion engine.

  • Patent number: 7575616
    Abstract: Embodiments of the present invention provide low-profile surface mount filters. One embodiment of the present invention includes a filter housing adapted to mount on a substrate block having a plurality of flow paths and a filter cavity defined therein. The filter cavity is defined to extend in a generally horizontal direction when the low-profile filter is in use. A first flow passage is defined to connect an inlet of the filter housing to a first section of the filter cavity and a second flow passage is defined to connect a second section of the filter cavity to an outlet of the filter housing. A filter assembly is disposed in the filter cavity and sealed to the surface of the filter cavity separating the filter cavity into adjacent sections including the first section of the filter cavity and second section of the filter cavity.

  • Publication number: 20080314009
    Abstract: A fiber bed mist eliminator has a fiber bed which is formed of a composite fiber bed collecting media strip including a collection layer which is not subjected to needle punching. The fiber bed can be made very thin while retaining high efficiency in removing small particles of aerosol from a gas stream passing through the fiber bed. The fiber bed collecting media strip lends itself to be applied to the mist eliminator by spirally wrapping the element onto the mist eliminator. The fiber bed collecting media strip can overlap itself to seal at the locations where the fiber element overlaps itself. The fiber bed collecting media strip can be provided to the field in different formats for use in making a mist eliminator fiber bed.
