Cyclonic separation is a method of removing particulates from an air, gas or liquid stream without the use of filters through vortex separation. When removing particulate matter from solid from gas, a gas cyclone is used. Rotational effects and gravity
are used to separate mixtures of solids.
Particles larger than the cut point will be removed with a greater efficiency and smaller particles with a lower efficiency as they separate with more difficulty or can be subject to re-entrainment when the air vortex reverses direction to move in direction of the outlet.
