KESD AC type
Working theory: Apply AC high voltage on the static emitter, to get positive and negative ions alternately. Use 50/60Hz frequency to generate ions
Advantage: Good ion balance with positive and negative ions generated at the same time
Disadvantage:
1. Long time gap between positive and negative ions, low ion density and low power
2. Few ions generated and low speed static eliminate
Safety:
6.0KV electric shock, strong keenly feel on the finger
KESD High frequency AC type
Working theory: Improved from normal AC type, Use 68/74KHz frequency to generate ions
Advantage:
1.Good ion balance with positive and negative ions generated(Mutual mixing) at the same time
2. Fast in generating the ions, high ion density, fast static eliminating
Disadvantage:
High ion density and powerful high require on the environment
Safety:
2.2KV electric shock, without keenly feel on the finger
Other brand DC type
Working theory: Apply DC high voltage on the static emitter, to get positive and negative ions constantly
Advantage: Good at long distance eliminating
Disadvantage:
Weak ion balance in short distance
Safety:
5.0KV electric shock, palm and forearm keenly feel
