The invention relates to an apparatus (10) for purifying gas while bleeding a crank housing, said apparatus (10) comprising a housing (12) inside which a separator chamber (14) is provided, a rotor arrangement with a rotor shaft (32) that is rotatably mounted in the housing and a centrifugal rotor (39) located in the separator chamber (14), and a fluid driving device (64) for driving the rotor shaft (32) by means of a driving fluid, the driving device (64) being disposed in a driving chamber (60) that is separated from the separator chamber (14) by means of a housing partition (16), and the rotor shaft (32) extending through a breakthrough in the housing partition (16). In the case of this device, it is provided that a labyrinth-type seal (70) is provided in the zone of the breakthrough in order to seal the driving chamber (60) from the separator chamber (14).
