In the untreated air chamber (24) formed in the casing (12) of a clean-room air outlet, a pipe section (38) is provided which is connected to the air inlet opening (18) and contains a shut-off element (34). The movable shut-off body which takes the form of a flap (46) is connected by means of a lever (48), which is mounted on the pipe section (38), to a servo motor (50) which is also supported by the pipe section. The flap interacts with a seat part (44), which is arranged in the pipe section, of the shut-off element. The pipe section is supported by an input stub (16) at one end and by a pedestal at the other end and is releasably connected to the said pedestal, which belongs to the casing. The parts fastened to the pipe can, together with the latter, be disassembled via the outlet aperture of the air outlet when the filter, which can also be disassembled via the outlet aperture, is removed. <IMAGE>
