  • Publication number: 20150071829
    Abstract: A honeycomb filter includes a honeycomb fired body made of silicon carbide particles. The honeycomb fired body includes cell walls, a peripheral wall, and a silicon-containing oxide layer. The cell walls are to define cells placed in a longitudinal direction of the honeycomb fired body. The cell walls have a thickness of about 0.2 mm or less. Each of the cells has a first end portion and a second end portion opposite to the first end portion in the longitudinal direction. Either the first end portion or the second end portion of the each of the cells is sealed. The peripheral wall constitutes a periphery of the honeycomb fired body. The peripheral wall has a thickness larger than the thickness of the cell walls. The silicon-containing oxide layer is provided on surfaces of the silicon carbide particles.

  • Publication number: 20150059301
    Abstract: A filter system is provided with a housing having a housing wall and a cover, the housing having a longitudinal axis. An inlet is arranged on the housing and feeds a fluid to be filtered into the housing. An outlet is arranged on the housing and discharges the filtered fluid. Filter elements each having at least one filter medium are arranged in the housing. At least one of the filter elements extends along the longitudinal axis. The filter medium has pleats extending along the longitudinal axis with outer and inner pleat edges. The outer pleat edges extend on the first side of the filter medium and the inner pleat edges on the second side of the filter medium and are opposite the outer pleat edges. The filter medium has a variable flow resistance along the longitudinal axis.

  • Publication number: 20150059300
    Abstract: A device for removing oil mist and odors from an airstream comprising a base having an air inlet in the lower end thereof for receiving an airstream. A first tubular filter has a first end and a second end. The first end is closed, and the second end is mounted on the base wherein the first tubular filter defines an inner chamber that is in communication with the air inlet. A second tubular filter is mounted on the base. The second tubular filter surrounds the first tubular filter and defines an outer chamber therebetween. An opening is formed through the base. The opening connects the outer chamber with the air inlet. A valve element is disposed in the base. The valve element allows flow from the outer chamber to the air inlet when pressure in the outer chamber exceeds pressure in the air inlet.

  • Patent number: 8968439
    Abstract: The composite microporour filter material comprises a base-cloth layer, an upper adhesion layer attached to a top side of the base-cloth layer, and a lower adhesion layer attached to a bottom side of the base-cloth layer. The base-cloth layer is made of either polymide yarn base-cloth, polysulfoneamide yarn base-cloth, or polytetrafluoroethylene filament base-cloth. The upper adhesion layer is made of a mixture of polysulfoneamide short-staple and polymide short-staple; the lower adhesion layer is made of a pure polysulfoneamide short-staple. The upper adhesion layer and the lower adhesion layer are attached to two sides of the base-cloth layer by entangling which is adopted by needle punching, spunlacing or a combination thereof. The present filter material is temperature-resistant and corrosion-resistant and has features of a low manufacturing cost and the high filter precision.
