Abstract

Il dispositivo comprende una pistola elettrostatica, costituita essenzialmente da un primo corpo tubolare, contenuto in un secondo corpo tubolare esterno in materiale poroso all'aria. L'intercapedine definita tra il primo corpo ed il secondo corpo esterno viene mantenuta a pressione superiore a quella ambiente in modo tale da impedire il deposito di polvere sul corpo esterno.(Fig. 1).
