DESCO 19587 – Ion Python Hand Gun Controller with Hose

• Requires compressed air to operate (not included)
• If being used with Nitrogen, tip will need to be replaced at the factory – please contact us for pricing
• Point of use ionizer
• Adjustable between 30-100 PSI
• Neutralizes electro-static attraction (ESA)

The Desco Ion Python Neutralizing Hand Gun is a ready-to-use unit designed for use in applications and areas where static can create manufacturing or handling problems. These units quickly and effectively neutralize bulk static charges and aid in controlling contamination by dislodging dust and debris attracted by static electricity. Airflow may be easily adjusted from a gentle stream to a powerful blast.

These units are designed for use in applications and areas where ElectroStatic Attraction contamination create manufacturing or handling problems (Ref: ESD Handbook TR 20.20 paragraph 5.3.6.5.2.4 Point of Use Ionization). The Ion Python meets or exceeds the recommended technical requirements of ANSI/ESD S20.20 tested in accordance with ANSI/ESD S3.1.

Air requirements

Always supply the Ion Python Hand Gun with filtered, dry noncombustible gases, such as compressed shop air or nitrogen. (If nitrogen is used, the tip will need to be replaced and the unit recalibrated. This MUST be done by the factory – please contact us for pricing). If the air is not dry, damage to the equipment may result and the warranty will be voided. Dirty air can introduce moisture and oil, contaminating the units’ emitter assembly along with the materials to be cleaned or neutralized. Filters must therefore be used at all times upstream of the air nozzle. A water trap-type pre-filter should be used in conjunction with an oil coalescing-type filter. Also drain all moisture traps regularly to prevent moisture in the line. Several drainings per day may be necessary, especially in areas of high humidity.

The Neutralizing Ion Python Hand Gun may be operated over a range of 30 PSI to 100 PSI. The specific pressure needed will depend upon the application. Pressures exceeding 100 PSI are not recommended since these higher pressures are detrimental to effective ion production. An air pressure setting of 60 PSI is recommended. Use the needle valve located on the back of the controller to properly adjust the air flow.

Theory of operation

The Ion Python and Neutralizing Hand gun employ high voltage AC to create a balanced ion field. AC systems utilize emitters that are switched rapidly between positive and negative high voltage, usually at the power line frequency (50/60 Hz). The emitter is located at the end of the nozzle. This emitter produces large amounts of positive and negative ions, which mix with the air supply and create a highly effective neutralizing field. Any material within this field will be neutralized rapidly. The air nozzles also eliminate contamination by dislodging dust and debris which is attracted to a material’s surface by static charges. Once static charges are neutralized, dust particles and other forms of contamination are freed and carried away by the air stream. Desco ionizers meet the ANSI/ESD S20.20 minimum recommended technical requirement range of less than ±50 volts voltage offset tested in accordance with ANSI EOS/ESD S3.1. Air Nozzle Ionizers provide ±20 volt balance.

Neutralization efficiency (decay time)

The comparative neutralization efficiency of ionizers is determined by a standard test published by the ESD Association Standard 3.1. The decay rates measured using this standard are shown in the chart below. This performance was measured with the air nozzle at a distance of 6” from the charged plate and utilizing an air pressure of 30 PSIG.
