Compact powerful 12KV negative ion generator cleans air of impurities and provides a fountain of fresh air. Negative ions are produced during thunderstorms and this 0.94" X 1.17" X 2.3" (excluding mounting ears) module produces the same. Can even operate from a 9V battery at slightly less output. Just connect 12VDC to the red and black power input leads and a tremendous quantity of negative ions will be emitted (6 million/CM3 at 12" from emitter brush). These units are also used by our customers to make "flocking" devices. Brand new custom made for us in China. Requires about 200mA for operation. Item #CEI-1212
