Simco-Ion Guardian CR2000 Cleanroom-rated Overhead Ionizing Blower is designed specifically for use in cleanroom applications. The Guardian CR2000 features a well-designed circuit that results in balanced delivery of positive and negative ions, which ensures that the unit will maintain an ion balance of 0 ±5V.  Balance stability is further enhanced by use of Simco-Ion unique “ion shields” at the fan outputs to reduce parasitic ion loss.

The Guardian CR2000 ensures cleanroom compatibility using specially chosen components and materials.  All fan and air bearing surfaces are manufactured free of silicones. Fan assemblies are particle-tested to ISO 14644-1 Class 4 (Fed Std. 209E Class 10) particle limits.

The Guardian CR2000 is also equipped with Simco-Ion built-in emitter point cleaner. A lockout switch prevents tampering with the desired performance level. Built-in balance and ion output monitors verify the presence of balanced, ionized air. A standard power outlet on each Guardian CR2000 blower allows for daisy-chaining up to 10 units.

Unlike some overhead ionizers which link to an external device to provide real-time monitoring, the Guardian CR2000 has sophisticated internal monitoring circuitry which provides assurance that the unit is ionizing and that the balance circuit is functioning.
