Abstract: Disclosed is a spray gun having a gas nozzle and a fluid nozzle, each of said nozzles being in cooperative spatial relationship with the other to cause a fluid stream issuing from the fluid nozzle to be atomized and sprayed as fluid particles by gas issuing from the gas nozzle. In a preferred embodiment the fluid nozzle orifice has therein an axially disposed rod to increase surface area from which said fluid particles can be formed, said rod being electrically grounded at least during fluid issue from the nozzle. The spray gun additionally has an induction charging electrode disposed adjacent the gas and fluid nozzles, said electrode defining a charging zone wherein an electrostatic charge is imparted to atomized electrically-chargeable fluid particles.
