A set of round nozzles, all supplied from a plenum with air under comparatively high pressure and low volume is employed for drying the sides and top of a motor vehicle during its departure from washing apparatus. The nozzles are employed at an angle, and are oscillated for thorough coverage although with a concentrated blast of air from each nozzle. Preferably the nozzles are slender cone shaped to provide holding power of the air blast to remain concentrated at high velocity at a significant distance away from the nozzle outlet, for effectiveness on outer surfaces of not only standard sized cars, but also surfaces of smaller cars which, because of smaller car size, may be farther away from one or more such nozzles.
