Abstract
A spray unit and process for controlled droplet atomization in which a tangential vortex type fan with wide mouth passes operation from low-to-medium pressures at high volume, passes air through a throat in which controlled droplet atomization of spray material is being achieved prior to emission from the fan in a plane generally parallel to the flow of air. The flow of air sweeps the droplets into a parallel orientation in substantial avoidance of contact of the spray material on the fan parts, throat or mouth thereof and the airflow confines the continuous core of controlled droplets and projects the protected spray toward a target. The spray units are arranged to permit plural end-to-end adjacent articulated mounting with directional adjustment and flexible conduits for power at the individual units, including spray material delivery and power to lineal actuators and are carriage mounted on wheels for easy movement in the target area.
