Bar type static eliminator (KD-309 series/KDB series)



  • DC-type units that eliminate static by generating ions
  • The good ion polarity balance ensures that there is virtually no reverse charging caused by ion irradiation.
  • The good ion polarity balance ensures efficient static elimination regardless of the polarity or potential of the charged object.
  • The long ion irradiation distance makes this unit suitable for static elimination from charged objects moving at high speed.
  • The unit emits an extremely small amount of ozone.
  • The current-limiting resistor of the ion-generating electrode, which minimizes electric shocks, ensures safety.
  • Being a DC-type unit, this static eliminator does not cause the surface potential fluctuation of the charged object that would be caused by a PULSE-DC-type unit.
  • The CKDB and KDB-SI-type units permit replacement of electrode needles.
  • An environmentally friendly static eliminator designed for low power consumption
