An electrogasdynamically powered electrostatic spray gun is provided which discharges a liquid stream toward an object to be coated therewith. A first seeded air stream is selectively discharged from the spray gun to effect atomization of the fluid stream into a circular pattern and a second seeded air stream is selectively discharged from the spray gun to modify the shape of the atomized stream. The first and second seeded air streams are fed to their respective discharging zones through separate conduits which are supplied from a single feed. The shaping stream of seeded air can be reduced and the portion of the seeded air stream which would normally flow therethrough is redirected to bypass same whereby an undesirably high back pressure at the outlet of the electrogasdynamic generator will be avoided.
