An air stream projecting device especially suitable for cooling, heating and ventilating large enclosures by providing both horizontal and vertical control of air streams. The device is usually mounted on the side or end of an air duct and serves as an outlet for the air contained in the duct under pressure. The device includes a rectangular frame in the opening in which a hollow barrel-shaped member is journaled for limited angular movement. One side of the barrel member is opened to the duct to receive air therefrom and the opposite side is opened to discharge air therefrom into the atmosphere of the enclosure. A wall surrounds the discharge opening of the barrel member and projects therefrom beyond the rectangular frame. Carried within the walled opening of the barrel member are a plurality of vanes for directing the discharging air. These vanes are preferably individually pivotally adjustable but may be connected together for joint pivotal movement.
