PROBLEM TO BE SOLVED: To adjust ion balance by a simple control.SOLUTION: A static eliminator 1A includes: a draft air duct (50) through which positive ions and negative ions circulates; an aperture (an air outlet 7, an opening 6a, a recess 6b) from which the positive ions and negative ions are discharged; a balance sensor (5) which detects the ion balance; a louver (4) which guides the positive ions and negative ions discharged from the aperture in a specific direction; and a louver drive control part (22) which controls the louver (4) direction in accordance with the ion balance. |
