Flexicon Corp.'s dust hood for bulk bag dischargers contains spillage and dust that can escape through seams in the bag and folds in the spout. The six-sided enclosure seats against the rim of a hopper or flange of downstream equipment, and is equipped with an exhaust port for dust collection and a hinged door with inspection window. The top of the enclosure contains a circular opening that allows passage of the bag spout to the equipment connection point. The flat bottom of the enclosure supports a Tele-Tube telescoping tube that pneumatically raises a Spout-Lock clamp ring which connects the clean side of the spout to the clean side of the equipment. Constructed of stainless steel finished to food, pharmaceutical and industrial standards, the dust hood is offered on all Flexicon dischargers including models requiring forklift loading of bulk bags, models that load bags using an electric hoist and trolley, half-frame dischargers that require a forklift or plant hoist, and split-frame dischargers for forklift loading of bags in low headroom areas.
