Combined direct and indirect charging system for electrostatically-aided coating system
View Patent ↗An electrostatically aided coating atomizing and dispensing apparatus includes an atomizer, a voltage block, a source of electrically non-insulative coating material to be dispensed from the atomizer, an indirect charging apparatus, and at least one source of high magnitude electrical potential. The source of electrically non-insulative coating material is coupled to an input port of the voltage block. An output port of the voltage block is coupled to the atomizer. The indirect charging apparatus is operatively mounted with respect to the atomizer. The at least one source of high magnitude electrical potential is coupled to an input port of the atomizer and to an input port of the indirect charging apparatus.
