The apparatus according to the invention comprises at least one treatment device (101) for receiving at least one workpiece, a rotor on which the treatment device is arranged, a fluid rotary leadthrough for feeding at least one fluid onto the rotor and/or for discharging at least one fluid from the rotor, the fluid rotary leadthrough having a journal and a sleeve, which at least in sections are sealed off from one another, and the journal being arranged rotatably in the sleeve. The proposed radial arrangement is particularly unsusceptible to faults and entails little maintenance.
