Farr’s new self-dumping hopper simplifies the disposal of dust captured by cartridge-style dust collection systems. The hopper is offered in two capacities, 1 cu. yd and 2 cu. yd, and is ideal for a full range of dry dusts, including those that must be reclaimed or recycled after the collection process. The entire hopper assembly is designed to provide easy dust disposal while protecting against dust leakage between the collector and hopper. A slide gate and flexible quick-disconnect hose connect the two components together, and the hopper lid is fastened with rubber clamps that create a gasketed seal to prevent dust from escaping.
