ABSTRACT:
An apparatus for drawing off dust-laden gases, especially in the art of dental technique, has a ring channel (15) which can be loaded with compressed air. The airstream which is provided by a compressed-air nozzle (26) performs an arcuate movement in the ring channel (15), whereby dust-laden gases are drawn in through an annular slit (22) and conveyed to an outlet channel (13). The apparatus is suitable for drawing off gases from containers. The apparatus serves for drawing off dust-laden air which is released when mixing solid substances, for example dental investment material, in a container (10).
