ABSTRACT:
An electrostatic spraying device in which liquid emerging from an outlet (24) of the device nozzle (12) is subjected to an electrical field sufficiently high for the liquid to be drawn from the outlet as one or more ligaments which break up into charged droplets to form the spray. In order to provide shock suppression, the electrical field is produced by means of high voltage circuitry having a bi-polar output with a frequency no greater than 10 Hz.
