Hammond DusKolectors® are independent dust collectors used for isolated machines that cannot be connected to a central dust collection system, or where no central system is available. In operation, the DusKolector® draws the dirty air inside itself where the heavier particles are deposited in a dirt container at the bottom of the machine; either a tray or a 55-gallon drum. The air then goes through filters which remove the finer particles, and the filtered air returns to the room. There is no waste of energy exhausting heated or cooled air to the outside of the building. DusKolectors® are available in three models: cabinet, cyclone, and CycloPlus.
