Cyclone Separator Working Principle (Dust Separator)

Dust is drawn into the main extraction system by a negative pressure created by a fan -usually a centrifugal fan-. The dust laden air then passes through a cyclone separator where most of the wood dust is separated from the air stream; the clean air is then discharged directly to ambient air whilst the wood dust is recycled or disposed of ...
