The difference between DC ion fan and AC ion fan
DC ion blower and ACIon fanThe difference is: the discharge electrode of the DC ion fan is composed of positive and negative discharge needles, and positive and negative air ions can alternately occur on a discharge needle of the AC ion fan, and the discharge electrode is composed of the discharge needle and the ground electrode.
When there is no wind supply from outside, the static elimination interval of the DC ion fan is a little farther. When there is wind supply from outside, the static elimination interval is mainly determined by the structure of the static eliminator, the size of the air volume and the strength of the high-voltage power supply.
Special attention should be paid here that the difference between AC and DC ion blowers is due to the difference in balance voltage between the two. Since the same discharge needle of the AC ion fan has both positive ion generation and negative ion generation, even if the discharge needle is worn out for a long time, it will not have a great impact on the ion balance. Therefore, in terms of the performance of ion balance, The performance of the AC ion blower is still good.
Because the discharge needle of the DC ion blower is composed of positive and negative two stages independently, the ion balance of the DC ion fan will be poor when it is used in occasions with close intervals. The discharge needles of other DC ion blowers will affect the ion balance due to their pollution level and environmental impact. In particular, the discharge needle has been used for a long time. Due to the different wear levels of the positive and negative discharge needles, even after cleaning, the ion balance cannot be corrected.
The DC fan is discharged by two sets of electrodes, and the discharge speed per second is 220 (V) volt 24 (KHZ) kilohertz, which is characterized by a large amount of ion generation, a fast discharge speed, and a good balance. The AC fan has only one set of electrode discharge. If it is 220 (V) volts, the discharge rate per second is 50 (HZ) Hz, if it is 110 (V) volts, it is 60 (HZ) Hz. Due to the discharge replacement process, it is easy to cause the phenomenon of reverse charging of the object, and the balance of the discharge speed is less than DC.
The DC fan has a high safety factor, and the weak current of the casing is only 0.06 mA, which has no impact on the human body.
