Cleanroom-rated Overhead Ionizing Blower with Ion Balance and Output Monitoring

Simco-Ion’s Guardian CR2000 Blower is designed specifically for use in cleanroom applications. The Guardian CR2000 features a patented circuit that results in balanced delivery of positive and negative ions, which ensures that the unit will maintain an ion balance of 0 ±10V. Balance stability is further enhanced by use of Simco-Ion’s unique “ion shields” at the fan outputs to reduce parasitic ion loss.

  • Inherently balanced to 0 ±10V
  • Ion balance and ion output monitors
  • Lockout key switch
  • Silicone-free component surfaces
  • Integrated emitter point cleaner


  • Electronics Assembly
  • Life Sciences
  • Back-End Semiconductor Processing
  • Flat-panel Display
