ABSTRACT:
A static charge control device is disclosed having laminar flow. The device utilizes a pair of spaced electrodes mounted adjacent to a pair of spaced apertures with the electrodes being positioned so as not to extend into the apertures. As specifically shown, a pair of needle electrodes are mounted on a mounting plate with each electrode being mounted above a different aperture in the plate with the needle electrodes extending outwardly from the mounting plate in a direction substantially normal thereto so that the tips of the electrodes extend in the direction of a laminar flow of air passing through the apertures in the plate, which air is provided by a fan positioned rearwardly of the mounting plate. Continuous positive DC voltage is applied to one needle electrode and continuous negative DC voltage is applied to the other needle electrode, and ions produced at the electrodes are layered onto the laminar flow of air passing through the apertures to thereby carry the ions toward a neutralizing area for neutralization of static charges thereat.
