The aeration device for stall spaces consists of a number of distributor devices for incoming air, arranged distributed in the ceiling region of a stall space, with in each case one incoming-air inlet connected to an incoming-air space or incoming-air duct, and of at least one extraction device for outgoing air with a suction blower and an outgoing-air duct connected to the stall space on the suction side. Each extraction device forms a structural unit which comprises, arranged together next to one another in the outgoing-air duct, at least two suction blowers with in each case a drive motor which can be switched on and off independently. In this case, each extraction device is assigned a number of distributor devices equal to the number of its suction blowers, and a shut-off member which can be actuated by its own servomotor is arranged in the incoming-air inlet of each distributor device. Each drive motor of a suction blower of each extraction device is in each case connected to a servomotor for the shut-off member of a distributor device of the associated group in such a manner that, when the suction blower is switched on, the associated servomotor completely opens the air inlet of its distributor device and, when it is switched off, completely closes it.
