Pulse DC
Discharge effect is better compare to
frequency AC ionizing air blower
Pulse DC method generate ions with two polarity by
applying "+" and "-" high voltage alternately on positive
and negative electrode needles.
Compared with power frequency AC method, the
utilization rate of ion generation is higher. And its static
elimination ability can be exerted no matter in short or
long distance. In addition, the high voltage amplitude
can be adjusted, which is convenient for intelligent
control.
