  • Patent number: 7753982
    Abstract: A filter element comprising a filter jacket, a fluted filter media, and an internal seal is provided. The filter jacket defines a filter jacket inner surface, a gravitational bottom, an upstream end, and a downstream end. The filter jacket includes a moisture release aperture disposed proximate the gravitational bottom. The fluted filter media resides within the filter jacket and defines a filter media outer surface. The fluted filter media comprises a planar sheet and a fluted material intermittently bonded together and collectively coiled to form a plurality of flutes. First and second selected ones of the plurality of flutes are closed proximate the upstream and downstream ends, respectively. The internal seal is formed between the filter jacket inner surface and the filter media outer surface. The internal seal is disposed within the filter jacket between the upstream and downstream ends. The moisture release aperture is located upstream of the internal seal.

  • Patent number: 6994738
    Abstract: A snow filter for an airplane cabin air supply system is provided with a coned inlet screen which allows some air to pass through and some snow to be retained. The coned configuration diverts much of the air and snow toward a downstream conical retaining and collecting screen positioned toward the outlet of the snow filter. Snow is retained and collected at this point while air is able to pass through the screen. Downstream of the coned inlet screen and upstream of the conical retaining and collecting screen is an open air flow mid-portion that enables tortuous flow of air as the snow is directed toward the conical retaining and collecting screen in an annular collection volume. The outlet of the snow filter is provided with a contact sleeve that allows the snow filter to be fittingly received by a surrounding corresponding air duct. Thus a snow filter is provided that effectively separates snow from a flow of air while maintaining a clog-free path.

    Abstract: A waste stream separator separates liquid and solid waste from a conveying air stream. The liquid and solid waste are first separated from the air steam by gravity and filtration in a removable primary waste barrel. The air is then drawn through a secondary waste barrel and vacuum chamber with a moisture separator and water-resistant HEPA filter to produce dry, filtered air at the output port of the system. The liquid passing through the filter media in the primary waste barrel and the liquid collecting in the secondary waste barrel can be withdrawn for further treatment. When filled with waste, the primary waste barrel can be readily removed and sealed for disposal. If necessary, polyacrylate can be injected into the primary waste barrel to convert any remaining liquid to a solid gel prior to disposal.

  • Publication number: 20040088957
    Abstract: A waste stream separator separates liquid and solid waste from a conveying air stream. The liquid and solid waste are first separated from the air steam by gravity and filtration in a removable primary waste barrel. The air is then drawn through a secondary waste barrel and vacuum chamber with a moisture separator and water-resistant HEPA filter to produce dry, filtered air at the output port of the system. The liquid passing through the filter media in the primary waste barrel and the liquid collecting in the secondary waste barrel can be withdrawn for further treatment. When filled with waste, the primary waste barrel can be readily removed and sealed for disposal. If necessary, polyacrylate can be injected into the primary waste barrel to convert any remaining liquid to a solid gel prior to disposal.

  • Patent number: 6680028
    Abstract: A portable air purifier system and apparatus which includes a multi-element filter pack that is replaceable as a single unit, thus facilitating health safety of maintenance personnel. By serially disposing filter elements in order of descending sizes of particulates, filtering is improved. Selectably includable within the filters are materials that are particularly efficacious in removing contaminants such as acetone, ammonia, ozone, carbon monoxide, carbon dioxide, ethanol, methane, ethane, methanol, formaldehyde, hydrogen sulfide and other hazardous substances. By including an ultra-violet light source directed onto an activated charcoal layer, germicidal action is facilitated, and noise is abated through the advantageous employment of an expanded plenum and multiple right angle bends in air passageways.
