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 device further includes a first port adapted to supply compressed gas to the coating dispensing device and a second port adapted to supply coating material to the coating dispensing device. The device further includes a multi-phase generator (38) having a shaft. A turbine wheel (40) is mounted on the shaft. Compressed gas coupled to the first port impinges upon the turbine wheel to spin the shaft, producing multi-phase voltage. The device further includes an electrode (62) adjacent the nozzle and coupled to the multi-phase generator to receive electricity therefrom to electrostatically charge the coating material.
