The ROLAND SelectPowderExtraction utilized three intakes installed at the area of the delivery stack, preventing powder from escaping at the delivery. Three additional downstream intakes also reduce the return of powder to the stack and dryer area. The powder-filled air is sent to the extraction cabinet at the core of the unit, and the air is removed, while the powder is collected into a collection bag. The level of the bag is monitored at the control console, and can be disposed of like any ordinary vacuum cleaner bag.
