ABSTRACT:
An extended range static eliminator for impinging a stream of ionized air upon light-sensitive articles to be neutralized includes a housing for directing air through an opening therein toward the articles and a plurality of pointed discharge electrodes supported in the housing across the opening and facing opposite the air stream. The electrodes are preferably capacitively coupled to the high side of an A.C. power source to reduce likelihood of arcing while a conductive casing connected to the other side of the power source partially encircles the discharge electrodes to shield the high voltage field at the base of the electrodes from the ions emitted from the points thereof and further shield the sensitive articles from corona developed around the points.
