Abstract

An electrostatic spray gun for spraying solid particulate powder materials while entrained in a gas medium, including an electrically non-conductive housing having an electrode extending forwardly therefrom and a straight electrically non-conductive powder transport tube adjustably and replaceably mounted within the housing so as to enable the discharge end of the tube to be positionably adjusted relative to the electrode or to be replaced with a tube of differing internal diameter so as to vary the transport velocity at which the powder is emitted from the discharge end of the tube.
