The Flexicon Basic Filler for bulk boxes, totes, bins or other intermediate bulk containers (IBCs) loads bulk solid materials free of dust. The unit's fill head can be raised or lowered using a forklift and secured with clevis pins to minimize the clearance between the rectangular dust hood and the opening of IBCs ranging from 48 to 78 inches tall. A fill head port can be vented to a filter sock to contain displaced dust, or to a central bag house that causes a clear flexible skirt to vacuum-seal against the container's exterior, increasing dust containment effectiveness. Rated for loads up to 6500 pounds, the frame is offered in carbon steel with durable industrial coating, with stainless steel material contact surfaces, or in all stainless construction to industrial or sanitary standards.
