L'unité de charge, dotée d'un générateur d'ions de commutation de distribution, comprend : une partie source d'alimentation ; une pluralité d'électrodes comportant chacune une extrémité connectée à la partie source d'alimentation ; et une pluralité de modules de borne connectés respectivement à l'autre extrémité de la pluralité d'électrodes, disposés de manière à être espacés à proximité les uns des autres, et comportant une pluralité d'électrodes de décharge. Les poussières fines chargées lors du passage à proximité des électrodes de décharge sont rendues plus grosses, et ainsi l'efficacité d'élimination des poussières fines peut être améliorée.
