Ion Python Hand Gun (Controller with Hose)

Description

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 Ion Python meets or exceeds the recommended technical requirements of ANSI/ESD S20.20 tested in accordance with ANSI/ESD S3.1. Ionizers are useful in preventing electrostatic charge generation, ElectroStatic Discharge, ElectroStatic Attraction, as well as preventing equipment latch-up and safety related shock. ANSI/ ESD S20.20 Paragraph 6.2.3.1 Protected Areas Requirement states: “Ionization or other charge mitigating techniques shall be used at the workstation to neutralize electrostatic fields on all process essential insulators if the electrostatic field is considered a threat.” Ionization is used to neutralize charges on process necessary insulators and isolated semiconductors. Some examples of process necessary insulators are: the PC board itself, plastic test stands, plastic housing where a PCB may be mounted, as well as computer monitor screens and regular cleaning wipes. Examples of floating or isolated conductors are: loaded PCB mounted in a stand where the pins are not contacting the dissipative workstation. Ionization is not effective on items that have large capacitance, like people and carts; however, ionizers should be considered as a method for charge neutralization in cases where grounding cannot be achieved. Air ionization can neutralize the static charge on insulated and isolated objects by producing separate charges in the molecules of the gases of the surrounding air. When an electrostatic charge is present on objects in the work environment, it will be neutralized by attracting opposite polarity charges from the ionized air. Note that ionization systems should not be used as a primary means of charge control on conductors or people. (Reference: IEC 61340-5-2:1 paragraph 5.2.9). The Ion Python Neutralizing Hand Gun is NIST calibrated. They come equipped with universal IEC cord connectors. Neutralizing Ion Python Hand Gun Operation and Maintenance NOTE: These units are not recommended for continuous use. IONIZER SELECTION Plan Guidance states: “The Plan should include a listing of the specific type of ESD protective materials and equipment used in the Program.” When selecting an ionizer life cycle costs should be considered including: equipment cost; installation cost; and operation and maintenance cost. 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. Contact customer service at 909-627-8178). 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. Air Supply Connection Turn off air at regulator (or compressor). Insert the brass male connector (1/4” tubing to 1/8” pipe thread) into an available port on the regulator. If all ports are being used, a “T” or “+” may be added to create more ports. Connect the 1/4” tubing to the male connector on the needle valve on back side of the unit, following the instructions given below. To connect tubing or filter to quick connect fitting: Cut end of plastic tubing square and clean. Push against the collar with thumbnail. While holding collar in, push tubing into the fitting until it bottoms out completely. To release tubing or filter from quick connect fitting: Push against the collar with thumbnail. While holding collar in, push tubing inward slightly, then pull tubing out. MODEL STYLE VOLTAGE AC IEC CORD
