Cyclone dust collectors are used as product receivers, as pre-cleaners to high efficiency fabric-type dust collectors, or simply as independent collectors for coarse dust.
As the dirty air enters the cyclone dust collector, it is forced into a swirling movement. This results in a centrifugal force acting on the dust particles suspended in the air stream. The particles, denser than the air, are forced to move outwards, towards the cyclone dust collector wall. They then fall downwards, towards the dust exit. The clean air is eventually directed towards the centre of the cyclone and leaves through the gas exit.
