Abstract
The invention relates to an air separator having a rotor provided with feed passages for the material to be separated which extend radially outward and between which extraction openings are arranged. The space between adjacent feed passages which exists between the outer end of the feed passages and the extraction openings is axially delimited on at least one side by a stationary element forming part of an extraction housing. In this way, problems of wear in the outer region of the rotor are reduced. In addition, there is no longer any need for an exact sealing gap to be maintained between the rotor and the extraction housing. Finally, the free flow cross-section for the separation air is increased for the same overall dimensions of the separator.
