摘要： A device for generating gas bubbles in a liquid in a container includes a rotatable gas-permeable hollow shaft arranged in a container, gassing discs arranged on the hollow shaft and spacers arranged between the gassing discs, gassing discs and spacers being arranged alternately on the hollow shaft in gas-tight contact with one another, a feed line for a compressed gas into the interior of the shaft, spacer having a centered opening (O) for receiving the shaft and at least two chambers, the chambers being equally spaced around the centered opening, where the centered opening and the chambers at least partially overlap, where the centered opening and the chambers are in communication with one another at least in the overlap region, so that the compressed gas can flow from the shaft into in each case a chamber of the spacer and enter the gassing discs from the chamber of the spacer.
