Using steady state DC ion emission, the SCS Overhead Air Ionizer 991 provides consistent static control coverage. With its overhead mounting system, the ionizer doesn't compromise valuable space on the workbench, allowing for neutralization of static charges. The steady-state DC ion emission enables fast discharge with low airflow, providing a more comfortable work environment for operators. Emitter points are placed behind the fan to eliminate field-induced charge and to ensure a homogeneous mixture of ionized air. Also featured are open-cell foam filters on the fan intakes, protecting the internal components from environmental contamination.

Features and Benefits
■ Alarm relay closure circuitry
■ Bi-color LED indicator
■ 44 inches with three fans
■ High and low speeds
■ Self balanced; no calibration needed
■ Visual performance indicator: Green for normal operation and red signals an operational failure alarm
■ Broad static neutralization over the workbench
■ Reduces manual emitter point cleanings

Auto-Clean System
The Auto-Clean System features a brush mechanism that sweeps the emitter points when the ionizer is turned off and on, allowing the ionizer to always perform at optimum ion output and balance. During operation of the fan, the brush automatically retracts to prevent emitter point wear. The Auto-Clean System brush will extend as the fan slows to a stop. SCS recommends activating the Auto-Clean System at least once a week. Cleaning schedules will vary depending on environmental conditions and application requirements. This automated feature results in reduced operation costs due to lower maintenance.
