What is the difference between a DC ion fan and an AC ion fan?
(1) The DC ion fan mainly emits positive and negative ions synchronously by two sets of discharge electrodes, and also emits negative ions when emitting positive ions, thereby achieving the effect of eliminating static electricity.
(2) The AC ion fan mainly emits positive and negative ions from a set of discharge electrodes, first emitting positive ions and then emitting negative ions or first emitting negative ions and then emitting positive ions, which are all completed by a set of discharge electrodes, and have a time difference.
(3) In comparison, the DC ion fan has a short elimination time for static electricity, a large ion emission amount, and a wide effective range.
1. Characteristics of AC ion fan
(1) The polarity of the electrode changes at a frequency of 50 cycles/second, and the generated positive and negative ions are periodically changed, so that the self-neutralization rate is high and the neutralization efficiency is low.
(2) In order to reduce self-neutralization, the wind speed must be increased, which may cause physical discomfort to employees.
2. Characteristics of DC ion fan
(1)
The positive and negative electrodes are separately set, the self-neutralization rate is significantly reduced, and the neutralization efficiency is the highest.
(2) The feedback system can adjust the polarity and quantity of the ion output according to the actual situation. In order to achieve stable neutralization. .
