ABSTRACT:
An air distribution outlet device is provided having an elongated barrel with an inlet at the top end and a closure at the bottom end. A longitudinally extending wall portion of this barrel is formed with a multiplicity of orifices around the entire periphery for a predetermined axial length thereby permitting transverse outflow of air from the barrel. A flow-control deflector valve is disposed in this intermediate perforated portion of the barrel intermediate the extremes of the axial length of the perforations thereof and this valve is selectively adjustable between a position which is substantially blocking air flow therebelow to a position substantially unrestrictive to the flow of air through the entire perforated portion. This deflector valve may be selectively positioned at any position between the extremes thereby permitting control of the air flow in an upward or downward direction as desired as it is being diffused transversely through the perforations in the barrel. In order to further enhance this control of lateral air distribution, the barrel is provided with means for rotating it about its longitudinal axis.
