ABSTRACT:
A coating dispensing device includes a trigger assembly for actuating the coating dispensing device to dispense coating material and a nozzle 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 having a shaft. A turbine wheel 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 adjacent the nozzle and coupled to the multi-phase generator to receive electricity therefrom to electrostatically charge the coating material.
