For a more complete technical description of this process, see the article on "Cyclonic separation".

On Earth, air and powder streams are segregated using gravity or cyclonic separation.

Portable vacuum cleaners working on the cyclonic separation principle became popular in the 1990s.

Cyclonic separation: A vacuum cleaner employing this method is also bagless.

Since Dyson's success in raising public awareness of cyclonic separation, several other companies have introduced cyclone models.

Separating particles from an air-flow using cyclonic separation.

A Dyson vacuum cleaner uses cyclonic separation to remove dust and other particles from the air stream.

The droplets agglomerate to larger drops and the swirl of the gas causes cyclonic separation.

A cyclonic separation system, if used, does not lose suction as the collection container fills up, until the container is nearly full.

In 1979, James Dyson introduced a portable unit with cyclonic separation, adapting this design from industrial saw mills.

At the time Dyson had the idea of using cyclonic separation to create a vacuum cleaner that would not lose suction as it picked up dirt.

Note that if the densities of the particle and fluid are equal, the solution is and cyclonic separation is not possible.

Filterless cyclonic separation systems only require emptying the dirt collection container before the suction drops off as an almost-full condition is reached.

He is best known as the inventor of the Dual Cyclone bagless vacuum cleaner, which works on the principle of cyclonic separation.

Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation.

Hydrodynamic separators (HDS) are stormwater management devices that use cyclonic separation to control water pollution.

Dodington's most famous resident is James Dyson, inventor of the Dyson cyclonic separation vacuum cleaner, who bought Dodington Park in 2003.

The design of the sprue and runner system can be also utilized to trap unwanted dross and sand from continuing into the main cavity; this may include adding porous material to the runners, or designing the sprue to eject the dross to the side of the sprue using cyclonic separation.
