Abstract | A cyclonic separation device comprises a cyclone chamber 11 having a cyclone axis A, a fluid outlet at one end of the cyclone chamber and a tubular apertured shroud 14 extending concentrically with the cyclone axis A. In use a motor 15 rotates the shroud 14 in the direction of a rotational airflow in the chamber 11 at a rotational speed which is over 1500 rpm and/or over 70% of the airflow speed around the shroud 14. The high speed of rotation of the shroud 14 is sufficient to dislodge any dust on the shroud by centrifugal action. Also, the high rotational speed of shroud 14 means that the air does not to need to decelerate to pass through the shroud 14 apertures and hence the risk of pressure drop and a loss of suction is avoided. |
