  • Patent number: 10195555
    Abstract: A filtration media with improved filtration, strength, tear resistance and air permeability in the form of a relatively thin and lightweight wet-laid fibrous web that has a wet Mullen ratio of 60% to 80% to ensure that the media is flexible enough to be formed into a fluted structure, and strong enough to retain the fluted structure when wound into a roll and to permit further processing without the media becoming too brittle. The filtration media comprises a blend of cellulose and synthetic fibers having a weight percent of 81 wt % to 87 wt % of a weight of the media and a resin binder having a weight of 13 wt % to 19 wt % (preferably about 16 wt %) of the weight of the media.

  • Publication number: 20140190356
    Abstract: A filter used to reduce the emission of silica particles used in hydraulic fracturing. The silica reduction cover is a custom fit filter installed onto vent hatches of proppant storage trailers. Proppant storage trailers, or “frac sanders,” have a series of vent hatches that release air and fine particles into the atmosphere during material transfer operations. The silica reduction cover is comprised of filter material and permits the controlled release of high pressure air at each vent hatch while reducing sand particle loss. The silica reduction cover maintains proppant sand product in the trailer for production use while significantly reducing the emission of airborne sand particles in the immediate work and adjoining site areas. The silica reduction cover incorporates a viewing window so that workers may monitor proppant levels in the storage trailer while the silica reduction cover is installed.

  • Patent number: 8734555
    Abstract: This disclosure describes examples of a seal element that can prevent leaks that occur due to sagging and/or displacement of a filter device from the tubesheet in a power generating system. The seal element can have a non-uniform profile that defines a material thickness for the seal element. In one example, the non-uniform profile defines an area or section of the seal element that is thicker relative to other areas or sections of the seal element. The thicker area corresponds to certain positions on the filter device that are susceptible to movement that can occur, e.g., due to particulate build-up during operation of the turbo-machine.

  • Patent number: 8048182
    Abstract: Embodiments of the invention generally provide a containment system having integrated bubble tight-dampers. In another embodiment, the containment system includes an integral auto-scan mechanism disposed in the housing of the containment system so that a filter element, disposed in the housing, may be leak tested without accessing the interior of the housing. In yet another embodiment, a method for testing a filter disposed in a containment system includes challenging an upstream side of a filter element disposed in a housing of the containment system with a test aerosol, and automatically moving a probe disposed within the housing to obtain samples for leak testing.

  • Patent number: 7972403
    Abstract: A filter apparatus includes a filter housing having at least one opening and a plurality of retention tabs positioned proximate to at least one of the openings and secured to the filter housing. Also included is a connection fitting having a tube segment sized and configured to be received into at least one opening of the filter housing, orientation tab or tabs secured to the connection fitting and positioned to be engageable between a portion of the plurality of retention tabs when in the installed position. A retention flange extends radially from the tube segment and is configured to retentively engage with the retention tabs to secure the connection fitting to the filter housing. The connection fitting is rotatable when the tube segment is received into the filter housing but is then rotationally locked relative to the filter housing when in the installed position.

  • Patent number: 7959698
    Abstract: A smoke evacuating system for use during surgical procedures, particularly minimally invasive procedures involving the use of a laser or cautery at a surgical site having an associated higher than ambient pressure, wherein the system includes a filter with a site side and an outlet side and a fluid conduit extending between the surgical site and the filter. The filter includes a filter media and a housing substantially surrounding the filter media with a space between the filter media and the housing to collect condensed vapor. The filter exhibits low resistance or a low pressure drop and resists fluid flow, whereby the higher than ambient pressure is not substantially diminished and generates a fluid flow in the fluid flow path tending to carry smoke to and through the filter.

  • Patent number: 7854780
    Abstract: An air-filter assembly is adapted to be used with a velocity stack of a carburetor of an internal-combustion engine of an automobile. The air-filter assembly includes a generally hollow air-filter member defining an open face, a closed face, and a side connected to and extending between the open and closed faces of the air-filter member. The closed face and side define an air-inlet end, an air-discharge end disposed opposite the air-inlet end, and an air filter arranged between the air-inlet and air-discharge ends. The air-inlet end is adapted to permit air to flow therethrough from exterior the air-filter assembly. The air filter is adapted to remove impurities entrained in the airflow and permit the filtered air to flow therethrough. The air-discharge end is adapted to permit the filtered air to flow therethrough into the velocity stack.
