     An aspect of certain embodiments described herein is a method to deliver high velocity air from a rotating air distribution manifold which can continuously pass through multiple rotational axes so as to discharged air into every or substantially every spherical direction in order to impact all or substantially all surfaces on or within a structure. Certain embodiments utilize two rotating air couplings that operate in series. Each air rotating air coupling can be coupled to a corresponding air manifold. One or both air manifolds can have one or more small thrust jets that can be self-powered by the same pressurized air supply that used for one or more high velocity discharge nozzle through which high velocity air can flow. In this manner, rotation of the high velocity air nozzle manifold in the X and Y axes can be achieved. An advantage of certain embodiments is that high velocity air from the high velocity air nozzles can continuously pass through multiple rotational axes to ensure that air is blowing onto all or substantially all internal or external surfaces of a structure. With the use of two continuously rotating air coupling assemblies operating in series, through which rotation is achieved by the small thrust jets, certain embodiments do not requires gears, belts, motors or other external drive components. In certain embodiments, the speed of rotation can also fully adjustable by adjusting the size and/or orientation of these thrust jet to optimize for each application. The pressurized air supplied by a blower or compressor passes can pass through a stationary shaft of each air coupling into a rotating perpendicular air transfer point which can serves as the inlet duct to each air distribution chamber. The result can be a continuous spherical motion of high velocity air discharge to accelerate surface drying and/or particle removal from a wide variety of geometric shapes.
