Principle of Electrostatic Elimination by Ion Fan Corona
The static eliminator can also be called an ion fan device, and its principle is as follows. It is composed of a high-voltage power generator and a discharge electrode (usually made of ion needles). The air is ionized into a large number of positive and negative ions through high-voltage corona discharge, and then a large number of positive and negative ions are blown to the surface of the object to neutralize static electricity, or Directly put the static eliminator close to the surface of the object to neutralize static electricity.
DC ion fan corona products
The DC high voltage generator raises the 220V input voltage and outputs positive and negative voltages respectively. A strong electric field is generated between the positive and negative discharge electrodes. Air molecules are ionized. The tip of the positive discharge electrode generates positive ions, and the tip of the negative discharge electrode generates negative ions. Negative ions are generated at the same time to neutralize the static electricity on the surface of the object. When the surface of the charged object is at a positive potential, the negative ions will neutralize it. On the contrary, if the surface is at a negative potential, the positive ions will neutralize it. DC corona products can generate positive and negative ions without grounding. There are sufficient positive and negative ions on the surface of the object, and the speed of neutralizing static electricity is very fast.
