  • Patent number: 10434449
    Abstract: A filter retaining mechanism for retaining a filter and a pre-filter in relation to a filter aperture of a filter frame. A base clip retained by a proximal portion of a shank engages a flange of the frame, and a filter/pre-filter clip is retained by a distal portion of the shank. The filter/pre-filter clip has a proximal retaining formation that forms a distal retaining surface of a first reception area for retaining a filter and a proximal retaining surface of a second reception area for retaining a pre-filter and a distal retaining formation that forms a distal retaining surface of the second reception area. The filter/pre-filter clip is pivotable about a longitudinal axis between a first condition wherein the proximal and distal retaining formations retain the filter and the pre-filter and a second condition wherein the proximal and distal retaining formations face away from the filter aperture to release the filter and the pre-filter.

  • Patent number: 9440174
    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.

  • Publication number: 20140041348
    Abstract: An accessory cap for a respiratory cartridge includes a housing having a front wall and a side wall which cooperate to define an interior cavity. The side wall includes a retaining formation configured and arranged to releasably engage and hold the housing on the respiratory cartridge. The housing includes a downwardly facing air passage configured to allow air to pass from an exterior environment to the interior cavity. The accessory cap further includes a pre-filter support web removably received within the interior cavity and spaced inwardly from the front wall. The housing and the pre-filter support web form a pre-filter cavity within the interior cavity adjacent to the front wall. The accessory cap can function as a standalone shower cap, or a pre-filter media can be optionally inserted into the pre-filter cavity so that the accessory cap functions as a combination pre-filter and a shower cap.
