Ionizing air nozzle is a small static elimination device, the main working principle is the ionization of air into a positive and negative ion charge, with the air flow to the surface of the object, so as to neutralize the electrostatic charge. According to its discharge principle, it can be divided into high-frequency AC ion nozzle and DC ion nozzle. According to the different power supply interface, it can be divided into, power ion nozzle and network ion nozzle. It is mainly used in small areas and can remove the static quickly. Row type ionizing air nozzle can be used in the production line, which can move evenly and will achieve the overall static elimination operations. Kesd has designed one automatic induction ionizing air nozzle, which can induce the object and can work automaticlly.
