A coating dispensing device (20) includes a trigger assembly (26) for actuating the coating dispensing device to dispense coating material and a nozzle (30) through which the coating material is dispensed. The coating dispensing device further includes a first port (34) adapted to supply compressed gas to the coating dispensing device and a second port (36) adapted to supply coating material to the coating dispensing device. The coating dispensing device further includes a generator (38) having a shaft (42) and a turbine wheel (40) mounted on the shaft. Compressed gas coupled to the first port impinges upon the turbine wheel to spin the shaft, producing voltage. The coating dispensing device further includes an electrode (62) adjacent the nozzle and coupled to the generator to receive electricity therefrom to electrostatically charge the coating material and a regulator coupled to the generator for regulating the voltage generated by the generator. Compressed gas which spins the turbine wheel also flows past the regulator to remove heat from components of the regulator.
