It consists of a high-voltage power generator and an electrode (usually in the form of an ion needle), which ionizes air into a large number of positive and negative ions through the corona discharge at the tip. These ions are then blown onto the surface of an object by wind to neutralize static electricity, or the static eliminator can be brought close to the object's surface to neutralize the static directly.

AC Corona Discharge Products

The AC high-voltage generator boosts a 220V input voltage to over 4KV, with the electrodes alternating between positive and negative voltages at a 50Hz frequency. This creates a strong electric field between the electrodes and the ground, ionizing air molecules and causing the electrode tips to alternate between positive and negative ions. When the surface of a charged object is positively charged, negative ions neutralize it; conversely, if the surface is negatively charged, positive ions neutralize it. AC corona products must be grounded to operate properly, but some positive and negative ions are directed to the ground due to grounding. However, the structure is simple, and the balance of positive and negative ions is good.

2. Direct Current Corona Products

The DC high-voltage generator boosts a 220V input voltage to produce both positive and negative voltages. A strong electric field is generated between the positive and negative electrodes, ionizing air molecules. The positive electrode tip produces positive ions, while the negative electrode tip produces negative ions. The simultaneous generation of positive and negative ions neutralizes static electricity on the surface of objects. When the charged object's surface is positively charged, negative ions neutralize it; conversely, if the surface is negatively charged, positive ions neutralize it. The DC corona product can generate positive and negative ions without grounding, providing abundant ions on the surface of objects for rapid static electricity neutralization.
