Cyclones  and   Multi-Cyclones   provide ideal solution to the problem of collecting the shavings, extracted dust in wood working plants, bark & chips, and adapted in other dust extraction systems.Centrifugal force causes the  suspended material to move towards the wall of the cyclone from where the separating out material drops by gravity along the wall of the cyclone unit; leaving the air  to escape through the top. A number of small cyclone (collector) cells are grouped together to form  a multi-cyclone, which attain high efficiency due to its smaller diameter feature; and is simultaneously suitable for handling large air quantity.

The main advantage of cyclone include simplicity in design and construction, ease of operation and maintenance, has no moving parts and operates on a lower pressure drop  - thus requiring lower energy for dust separation . The main limitation is its inability to offer higher efficiencies for smaller and lighter particles. A number of cyclones can be operated in parallel to treat larger volume.
