Desco 19590 – Chargebuster Ion Gun

• Requires compressed air to operate (not included)
• Point-of-use compressed air ionizer
• Use filtered air or Nitrogen – no adjustment required; allows for quick change between the compressed gas supply
• Fast <1 second discharge times with ±30 volt offset voltage balance tester per ANSI/ESD STM 3.1 and ESD TR53

The Desco Chargebuster Ion Gun is a point-of-use ionizer used for neutralizing electrostatic charges to eliminate attraction, visual imperfections and contamination issues by dislodging charged dust and debris. It uses compressed clean dry air (CDA) or a compressed gas supply. Less than 1 second discharge times with ±30 volt offset voltage balance meet the required limits of ANSI/ESD S20.20 and ESD TR53. A 7-foot ESD hose with trigger switch allows operators freedom of motion and minimizes awkward or unsupported positions. The quick change filter in the console collects small residual particles.

Compressed Gas Requirements

NOTE: Failure to use clean dry air or nitrogen may result in damage to the Chargebuster Ion Gun that is not covered under the Limited Warranty.

The compressed gas supply must be clean dry air or nitrogen supplied by a delivery system that utilizes a refrigerated dryer or equivalent water removal to achieve a limit of about 550 ppm water vapor at 35°F (1.66°C) Dew Point. To prevent particles from entering the console, a 2 micron coalescing filter or better is recommended upstream of the gun console. Note that the filter in the console collects small residual particles and aerosols and does not act as a primary filter. The console filter is rated at 0.01 micron for particulates and is effective down to 0.008 micron for aerosols.

An adequate filter that can be recommended for the inlet of the Chargebuster Ion Gun would be a Finite Filter Grade 10 Media Specification. This provides a 95% coalescing efficiency for aerosols with a 0.7 micron (and greater) particle retention. This removes gross amounts of particles, water and/or oil and aerosols. A Grade 6 Media provides 99.98% efficiency when almost total removal of liquid aerosols and particles are required in all pressure ranges down to 0.01 microns. Fine filters need to be changed more often.
