Abstract

A centrifugal separator of vertical axis for the separation of a flowable medium, in particular a dental liquid/solids mixture, from conveying suction air has a motor-driven removal element (10) which is arranged in a flow chamber with a rotationally symmetrical peripheral wall (4) and a bottom limit. A top, central outlet (9) for the suction air and a bottom, peripheral outlet (8) for the flowable medium are flow-connected to an inlet (5) for the mixture to be separated, which opens out between these outlets, the peripheral outlet (8) being surrounded by an annular non-return valve (7). Vanes (16) are provided on the removal element (10) between the mixture inlet (5) and the peripheral outlet (8). The mixture inlet (5) is formed between the bottom edge of the peripheral wall (4) and a holding ring (22) for the non-return valve (7).
