cyclonic separation wikipedia

a 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 liquid a hydrocyclone is used; while from gas a gas cyclone is used. rotational effects and gravity are used to separate mixtures of solids and fluids. the method can also be used to separate fine droplets
