In spite of what some would like us to believe, dust collection cyclones are simple tanks with no moving parts and have been used for dust separation for over seventy years. They are made up of just a few parts, an air inlet, an outer cylinder, an air outlet, and cone with dust chute that connects to a collection bin with flex hose. Dirty air comes in through an inlet and spins quickly around. This spinning throws the heavier particles outward to the cyclone walls. Airflow on the cyclone walls is slowed by friction.
