Cyclones are used to extract airborne wood dust particles from the air in the wood products workplace environment.

Dust laden air enters through the cyclone inlet. The high turbulence breaks the heavier and lighter materials apart.  The spinning air throws the heavier materials outward to the cyclone walls.  Airflow on the cyclone walls is slowed by friction.  Heavier dust particles get trapped in the slower moving air and gravity slowly pulls these heavier particles down.  These heavier particles continue to slide downward in the cyclone and eventually exit out through an air lock for collection in the residual collecting conveyor system.  Near the bottom of the cone is a reversal point where the spinning air without the heavier dust particles reverses direction. The cleaned air spirals up through the center of the cyclone then exits through the cyclone outlet.

The multi cyclone is a series of small cyclones and each small cyclone functions similar to a regular cyclone.  The dust laden air enters into the multiclone through the intake collector linking the tangential air intakes of the cyclones.  The centrifugal action of each cyclone causes the dust particles to fall into a common hopper where they are exited through an air lock to the residual collecting conveyor system.  The clean air is evacuated into the atmosphere.
