Abstract
A method of spraying a coating onto a substrate using low pressure, high volume air is disclosed. More specifically, the step of using a vortex tube with valves at both the hot and cold air discharge ends to supply the low pressure, high volume air to a spray gun is disclosed. The use of the vortex tube results in an inexpensive system, that can be used in electrically hazardous areas, and allows very precise control of air temperature.
