Abstract
A hand held electrostatic spray gun having an electrostatic power supply mounted in the gun. The power supply includes a circuit module mounted in the gun handle which produces heat during operation. The circuit module has a heat conducting housing which is intimately attached to a heat conducting tube extending through the handle. Compressed air delivered through the tube to a nozzle for assisting atomization and/or pattern shaping cools the circuit module.
