Which three sentences describe how a cyclone device works? This device removes particulates from the air by making a dirty air stream flow in a spiral path inside a cylindrical chamber. It consists of several long and narrow fabric filter bags suspended upside-down in a large enclosure. When dirty air enters the chamber, the particulates strike the chamber wall and fall into a conical dust hopper at the bottom. Fans blow dirt-filled air upward from the bottom of the enclosure, trapping dirt particles inside the filter bags. The top of the chamber has an outlet that lets out the cleaned air.
