The cyclone is a separator which uses centrifugal force to purify air contaminated with wooden chips or dust. Its output depends on the particle rotation speed, density and size. 99,9% of fresh saw dust is retained. This percentage is even higher in the case of dust of approximately 5 microns.

Standard cyclone is made of 2mm-thick steel sheets with an adjustable air-outlet pipe with rain protection and an adjustable valve. The structure can be strengthened to 3 mm.
