An electrostatic spray apparatus, including a spray hood having an electrode. The hood defines a top region with a depending skirt and comprises first and second hood elements, either or both of which may comprise molded shells, with an electrode sandwiched therebetween. The electrode extends over the top region and down the skirt and terminates short of the lower regions of the skirt. The hood is constructed such that, other than at the lowermost regions of the skirt, the hood does not have any junction of its planar surfaces having a radius less than one hundred and fifty millimeters. The hood has an opening in its top region, through which an electrostatic spray head is placed into the hood. The electrode presents a connection for an electrical supply, and the potential applied to the spray head is substantially the same as that applied to the electrode.
A spray hood, for an electrostatic spray apparatus, comprising a first hood element having substantially planar surfaces defining a top region with a downwardly depending skirt, which extends downwardly a given distance, and an electrode supported within said first hood element, characterized in that the hood includes a second hood element within the first hood element, the electrode is sandwiched between said first and said second hood elements and extends across the top region and extends downwardly for more than half of said given distance, and the spray hood does not have any junction of its planar surfaces, other than at the lowermost regions of said skirt, having a radius of less than one hundred and fifty millimeters throughout its construction.
