What is the difference between an AC ion fan and a DC ion fan?
The difference between the AC ion fan and the DC ion fan is that the alternating ion fan can alternately generate positive and negative air ions on one discharge needle, and the discharge electrode is composed of the discharge needle and the ground electrode, and the discharge electrode of the DC ion fan does not need to be The grounding electrode, the discharging electrode is composed of positive and negative independent discharge needles.
In the absence of external air supply (such as fans, compressed gas, etc.), the DC ion fan is farther away from the AC ion fan. In the case of external air supply, the static elimination distance depends mainly on the structure of the de-energizer. The amount of air volume and the strength of the high voltage power supply. The difference between the ion exchange fan and the DC ion fan is that the ion balance is different. The AC ion fan generates both positive ions and negative ions on the same discharge needle, so even after the discharge needle is worn for a long time, There is no major change in ion balance and ion balance performance is better.
DC ion blowers Because the discharge needles are composed of independent positive and negative electrodes, the ion balance is poor when used at close distances. In addition, the discharge needles are affected by the environment and the degree of contamination of the needles during use, which will affect the balance of ions, especially the discharge needles. After long-term use, the positive and negative discharge needles are worn to different extents, and the ion balance cannot be corrected even after washing.
