The air outlet chamber has a constant cross-section which consists of a number of wall parts. The wall parts are extruded profiles and have profiled ribs on their inside. In each case one profiled-rib pair serves for anchoring plates for holding ball-shaped nozzle bodies in wall openings of the air outlet chamber. Pushed onto edge profiles of the wall parts is a clamping element so that the wall parts are braced with one another. An inflow duct is connected to the chamber with its axis parallel to the wall parts. Wall parts bearing the nozzle bodies thus extend vertically into the room to be ventilated so that a good air distribution results via the pivotable nozzle bodies.
