How do corona ionizers work?
Corona ionizers work by applying high voltage to the tip of a sharp point. The geometry of the sharp point creates a high electrostatic field in the vicinity of the point, establishing what’s known as the corona region. The high electrostatic field interacts with the electrons in the gas molecules of the air in the corona region. With positive high voltage applied to the point, electrons are pulled out of the gas molecules and are attracted to the point. The gas molecules that have lost electrons now have a net positive charge, making them positive ions. The positive ions are in a region of high positive electrostatic field and are repelled away from the point into the work area. All types of corona ionization use high electrostatic fields to create air ions. The electrostatic field can move the ions to the work area, or some type of airflow can be used to move the ions more efficiently. Corona ionization is commonly found in 3 different forms, alternating current (AC), steady state di
