Abstract

An apparatus for electrostatically coating an object using electrostatically charged powder grains. The invention improves upon the spray bell sprayer by having a fixed hollow shaft providing a central supply line for the powder grains, the spray bell rotates about the hollow shaft and a plurality of compressed air nozzles pass radially into the hollow shaft.
