ABSTRACT:
An air regulator system for a powder coating system and method of operating the system whereby air regulators constructed with inexpensive, on-off servo control valves are positioned side by side and secured to a common bracket and are operated with a pulse width modulating circuitry that quickly and accurately controls the regulator. The circuitry is carried on a circuit board which is also mounted to the common bracket.
