Electrostatic air ionizer using double-pointed pins

The possibility of a technical solution has been experimentally proven, previously not found in electrostatic air ionizers – application for air ion emitters pins with two points. This solution is not only technologically simpler, but also improves air ionization with fewer pins. The article describes the design of such… Continue Reading
