Simco-Ion 4008729 Guardian CR2000 Cleanroom-rated Overhead Ionizing Blower
Part Numbers: 4008729 (Guardian CR2000 2-Fan, 120V, 60Hz, UL, North America), 4008630 (3-Fan, 120V, 60Hz, UL, North America), and 5050542 (Overhead Blower Daisy-chain Kit, 10’ power cord). The Guardian CR2000 Overhead Ionizing Blower comes in either 2-fan or 3-fan chassis lengths, each designed for optimal coverage area and a variety of applications.
Simco-Ion’s Guardian CR2000 Cleanroom-rated Overhead Ionizing Blower is designed specifically for use in cleanroom applications. The Guardian CR2000 features a patented circuit that results in a 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 the use of Simco-Ion’s unique “ion shields” at the fan outputs to reduce parasitic ion loss.
The Guardian CR2000 ensures cleanroom compatibility with all fan and air bearing silicone-free surfaces. Fan assemblies are particle-tested to ISO 14644 Class 4 (Fed Std. 209E Class 10) particle limits.
The Guardian CR2000 is also equipped with Simco-Ion’s patented 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 assures that the unit is ionizing and that the balance circuit is functioning.

Frequently Asked Questions
What are the part numbers for the Guardian CR2000?
The North America models are 4008729 (2-Fan, 120V, 60Hz, UL) and 4008630 (3-Fan, 120V, 60Hz, UL), plus the 5050542 Overhead Blower Daisy-chain Kit with a 10’ power cord. Continental Europe and United Kingdom 230V variants are also available.
What makes the Guardian CR2000 cleanroom rated?
It meets ISO 14644 Class 4 (Fed Std. 209E Class 10) cleanroom requirements, with all fan and air bearing silicone-free surfaces and fan assemblies particle-tested to ISO 14644 Class 4 particle limits.
How fast does it discharge charge?
Discharge time is 3.0 seconds at 18” (46 cm) from the center blower position, from 1000V to 100V with the fan on high, tested in accordance with ANSI/ESD STM3.1-2015.
What coverage area does each chassis length provide?
A 2-fan Guardian CR2000 provides coverage for a 2-foot by 3-foot area, and a 3-fan unit covers a 2-foot by 4-foot area.
Can multiple blowers share one power source?
Yes. Each Guardian CR2000 has a standard IEC320 power outlet that allows daisy-chaining up to 10 units in series from one power source; the 5050542 Daisy-chain Kit includes a 10’ power cord.
How does it maintain balance and prevent tampering?
The patented circuit maintains an ion balance of 0 ±10V, with “ion shields” at the fan outputs reducing parasitic ion loss. A lockout key switch prevents tampering with the desired performance level, and built-in balance and ion output monitors verify balanced, ionized air.
