Cyclone dust collectors are usually located prior to the dust filters located near the vacuum pump that drives the conveying system. When the air is pulled through the dust collector chamber toward the pump, it spins in a cyclonic motion at high speed. The centrifugal force, created by the circular air flow, directs the larger plastic particles, fibers, and dust toward the wall of the cyclone chamber. As they hit it and lose velocity, they fall down into a hopper/bin which is under the cyclone collector.
