  • Systems and methods for controlling particulate release from large equipment
    Patent number: 9669345
    Abstract: A containment system for reducing the release of harmful respirable particles through surface openings in equipment that carries sand includes a filter-receiving member configured to be coupled over an opening in a surface of the equipment and a filter member configured to be coupled to the filter-receiving member. The filter-receiving member can have a first side, a second side, and a passageway extending from the first side to the second side. The filter can have a porosity that permits air to flow through the filter member and restricts the flow of solid particulates.
