System collects dust created during manual dumping of powder and bulk solid materials from bags, boxes, drums, and other containers. Unit features high-velocity vacuum fan that draws airborne dust from the operator’s atmosphere onto 2 cartridge filters. Timer-activated solenoid valves release short blasts of compressed plant air inside cartridge filters, causing dust build-up on the outer filter surfaces to fall into the hopper. Filters are accessed easily by removing the interior baffle and replaced using quick-disconnect fittings.
