  • Patent number: 10399024
    Abstract: Surface modified filter media, including surface modified filter media having enhanced performance characteristics, are provided. In some embodiments, a filter media may comprise two or more layers designed to enhance fluid separation efficiency. One or more of the layers may have at least a portion of a surface that is modified to alter and/or enhance the wettability of the surface with respect to a particular fluid. In certain embodiments involving a filter media including more than one surface modified layer, at least one surface modified layer may have a greater air permeability and/or mean flow pore size than that of another surface modified layer. Such a configuration of layers may result in the media having enhanced fluid separation properties compared to filter media that do not include such modified layers or configuration of layers, all other factors being equal. The filter media may be well-suited for a variety of applications, including filtering fuel, air, and lube oil.

    Abstract: An air filtration for detecting hazardous particles includes a housing having an air flow pathway extending therethrough. The housing is configured to receive air flow from an inlet of the housing and to expel air flow from an outlet of the housing. A pair of electrodes are positioned within the air flow pathway. A sensor system is operatively connected to the pair of electrodes to measure electrical current flowing therebetween. A processor is operatively connected to the sensor system to compare the measured electrical current with a stored baseline current. An alarm is operatively connected to the processor. The processor activates the alarm when the measured electrical current is different than the stored baseline current.

    Abstract: A system for conditioning air flow to a gas turbine includes a filter housing and a conditioning media inside the filter housing to adjust the temperature of the air flowing through the filter housing. At least one of a depth or a density of the conditioning media varies across the filter housing. A method for conditioning air flow to a gas turbine includes flowing air through a filter housing connected to the gas turbine and flowing the air across a conditioning media in the filter housing. The method further includes conditioning the air flow to reduce the temperature difference of the air exiting the filter housing across a dimension of the filter housing.

  • Publication number: 20130019578
    Abstract: Various examples of the inventive subject matter include a method and corresponding system for fabricating a combination paint arrestance filter for use in the painting industry. Embodiments of the system include a single-stage combination filter having a number of first layer media pockets and a number of second layer media pockets arranged downstream of the first layer pockets. An opening of each of the first layer media pockets is arranged in parallel with one another to receive an incoming airflow into the single-stage combination filter. Each of the second layer media pockets is at least 99.97% efficient at removing 0.3 micron and larger particles at a face velocity on the filter of about 37 meters per minute.

  • Patent number: 8337597
    Abstract: A moisture diversion system for a gas turbine inlet. The moisture diversion system comprises a housing that is operably connected with a gas turbine and defines an opening through which air flows to the gas turbine. A hood is attached to the housing adjacent the opening. The hood has a surface disposed at an acute angle relative to horizontal. A device is disposed relative to the hood to separate moisture from air flowing through the device. Separated moisture is directed onto the hood. A gutter is disposed adjacent an edge of the hood to collect moisture from the hood. A conduit is fluidly connected with the gutter to conduct water away from the gutter and the opening in the housing to inhibit separated moisture from re-entering the air flow through the opening to the gas turbine.
