Abstract: A method and apparatus for air stream dispensing and spraying of pulverulent material with less noise is described using means for developing two separate outward air flows from a dispensing gun. One flow is of a high velocity and the second flow is of a lower velocity. After both flows leave the gun, the lower velocity flow surrounds the high velocity flow (e.g., as concentric annular flow about a columnar flow). Pulverulent material is fed to the lower velocity flow to be entrained therewith and transferred, at least in part, downstream from the gun to the higher velocity flow and thus finely dispensed over a desired area or product.
