A device, especially for directed blowing of large quantities of air into halls or the like, with at least one blowing nozzle whose direction is adjustable, contains a pressure chamber to receive the compressed air to be blown out, having on its outer surface one or more nozzle heads which have, in the side facing the general direction of outflow, one or more nozzles arranged in an end surface, essentially perpendicular to the general direction of outflow, such that the outflow direction of each nozzle is individually adjustable in a predetermined angular range.
