A manual dumping station with an integral, flexible screw conveyor collects dust from free- and nonfree-flowing materials ranging from large pellets to sub-micron powders, including those that pack, cake, seize, smear, fluidize, break apart or separate. During dumping from bags, boxes, drums or other containers, a high- velocity vacuum fan draws atmospheric dust onto two cartridge filters, accessed easily and replaced rapidly. Automatic reverse-pulse filter cleaning allows continuous, efficient operation. Timer-activated solenoid valves release short blasts of compressed plant air inside filters, causing dust buildup on outer surfaces to fall into the hopper.
