Abstract (en)
A cyclone dust extractor 1 comprising a housing 3 defining a first cyclone separator 23 and a second cyclone separator 33 in series, a centrifugal fan 11 for producing cyclones within the cyclone separators 23,33 and a motor 9 for driving the fan 11, wherein at least one of the cyclone separators 23 has an inlet portion 27 and an outlet portion 31 which are separated by a wall 35. As a result, the outlet portion 31 of the first cyclone separator 23 can act as a third cyclone separator. Additionally, unwanted turbulence between the inlet flow and the outlet flow of the cyclone through the first cyclone separator 23 is avoided. <IMAGE>
