The Centurion fan Ionizers use DC corona technology. They are designed for use in critical cleanroom applications. Centurion offers superior balance performance with its novel emitter array design and high-gain dual feedback circuitry. Using corona ion technology, the Centurion eliminates charges cleanly, quickly and reliably in cleanroom workstation applications where electrostatic discharge (ESD) is a concern. It is designed for applications where even very low levels of static charge can damage sensitive components. Ion balance is maintained with a high-gain dual feedback circuit. This circuit, combined with the unit's patented emitter array design, offer superior offset voltage performance. The unit is capable of maintaining +/-3V balance performance. If the unit becomes unable to track its setpoint or some other failure condition occurs, the built-in monitoring circuit indicates the fault condition. Specially selected components ensure cleanliness of the Centurion's output air to meet or exceed Class 10 particle limits. All fans feature a specially designed bearing system and use silicone-free lubricants. All air bearing surfaces in the ionizer are manufactured free of silicones. Fan assemblies are run-in and particle-tested to Class 10 (209E; ISO Class 4) particle limits. The Centurions final assembly, final test, and packaging take place in a Class 100 cleanroom to minimize risk of contamination.
