ABSTRACT:
An electrostatic sprayer device for spraying products in powder form comprises an air-powder mixture pipe with an ejector orifice at one end. It has a charging electrode adjacent this orifice and a counter-electrode coaxial with and to the rear of the charging electrode relative to the direction in which the mixture is ejected from the pipe. This counter-electrode is external to the pipe and substantially perpendicular to the axis of the pipe, with the result that an annular space is defined between the two electrodes and around the pipe. The electrodes have a potential difference applied between them to generate an electric field which attracts free ions towards the counter-electrode. A blower adjacent the counter-electrode discharges into the annular space formed between the two electrodes and around the pipe.
