Abstract: An electrostatic coating device (10) comprising a body defining to an interior chamber (13) communicating with the exterior by means of a first coating powder inlet conduit (14) and a second outlet conduit (15) for said powders, a plurality of electrodes (16) and one or more voltage generators (17) connected to said electrodes (16), wherein said electrodes (16) are positioned so as to generate an electrical field inside said second conduit (15).

Abstract: A paint booth for plants for painting products comprising: a supporting structure (10); one or more sheets (11), which define at least one portion of internal space (12) of said booth; and means (13) for surface treatment of said products. At least one of said sheets is mobile and has an opening through which said treatment means face within said portion of internal space, said at least one mobile sheet and/or at least one of said treatment means being connected to movement means (15), which impart a reciprocating motion simultaneously on said at least one mobile sheet and on said at least one treatment means.
