Bag dump station
August 21, 2015
Designed with an integral dust collection system, the Hapman bag dump station features a centrifugal blower that captures airborne particles as material is dumped into the hopper. Timer-activated solenoid valves release short blasts of compressed plant air into the cartridge filter; the reverse-pulse action causes the dust buildup on the filter surface to fall back into the hopper. The self-contained filtration system allows for 99.9% retention down to 1 micron.
