Product features

BF-X4ME is an updated model of BF-X4MB and thin and lightweighted air ionizer product, which can eliminate a wide range of statics up to 400mm. HDC-AC ionizer ensures the long-term stability of static elimination performance and extends the longevity of maintenance duration.

  • Wide range static elimination upto 400mm.
  • HDC-AC transformer gives long-term stable static elimination perofrmance.
  • Resin-made casing reduced weight.
  • Use two120mm fan motors (continously changeable) to produce large amout of airflows with high-speed static elimination.
  • Easy to detach parts for maintenance as louver and emitter needles only need a finger press to detach from the unit, no extra tools needed.
  • Safety design
     - power off for louver removal.
     - micro-discharge and over-current detection.
  • Adjustable angle with lock function to prevent change of angle due to vibration.
