SCS 991A – Overhead Ionizer, North American Power Cord

• Three-Fan AC ionization for 2ft x 4ft coverage area
• Airflow: 150-200 CFM
• Ion Emission: AC Ionization
• Balance (offset voltage): +/- 10V
• Discharge time: < 3 seconds at 18in

The SCS 991A Overhead Air Ionizer is designed for use with sensitive electronic components where electrostatic discharge (ESD) is a problem. The 991A Overhead Air Ionizer provides fast static charge decay efficiency over an entire worksurface area. Equipped with task lighting, an ionization indicator light, and an integrated heater, it offers user-friendly operation while helping protect even the most sensitive components from ESD damage. The SCS 991A Overhead Ionizer easily meets the ANSI/ESD S20.20 required limits for ionization use in electronics manufacturing areas tested per ANSI/ESD STM3.1 and ESD TR53.

The SCS 991A Overhead Air Ionizer produces an air flow that is rich in positive and negative ions. Directing the air flow on an object that has a static electricity charge will neutralize the charge. If the object has a positive static charge, it will draw negative ions from the air flow. If the object has a negative static charge, it will draw positive ions from the air flow. The ions are attracted to the oppositely charged object and will neutralize the electrostatic charge on the object.

The 991A Overhead Air Ionizer features both inherent self-balance technology and a built-in emitter point cleaner. The 991A Overhead Air Ionizer operates on AC technology to provide stable balance performance over long periods of use. The 991A Overhead Air Ionizer provides fast charge decay directly under the unit for targeted worksurface coverage. The 991A Overhead Air Ionizer requires very little maintenance to ensure electrostatic charge is controlled within the worksurface area.
