Cleanroom Ionizing Blow-Off Gun

Quickly and safely neutralizes static surface charges to protect sensitive parts from electrostatic discharge (ESD)
Uses a burst of clean, dry air or nitrogen to dislodge and remove particles held by static attraction
Low-voltage power supply provides a balanced stream of ions with minimal interference (EMI/RFI)
Discharge time: 1000V to 50V in less than three seconds (inlet pressure of 30 psi, measured at 6" from target)
Durable polymer casing is ergonomically designed and features a smooth-pulling trigger
In-line capsule filters ensure purity of gas feed (clean, dry air or nitrogen)
Includes the appropriate power transformer and a convenient hanging bracket
Applications: static control for microelectronics, medical devices, sterile packaging, non-conductive materials, pharmaceutical/nutraceutical powder residues

Safe Design for Personnel and EMI-Sensitive Equipment

The step-down transformer allows the anti-static Ionizing Blow-Off Gun to be plugged into a standard outlet while the system operates at a much lower level of 24 VAC. This significantly reduces the potential shock hazard and it also minimizes EMI (electro-magnetic interference), making it safe for operation around high-precision electronic equipment.

Lightweight and Ergonomic for Comfortable, Regular Use

All components are designed for cleanliness, durability, and safety. The rugged polymer case is designed to minimize strain to operators wrists and hands. The scalloped nozzle tip safely recesses the ion emitters to guard against contact with operator or parts. The anti-static gun uses either filtered air or nitrogen to provide the dispersing force necessary to direct the ions to the target surface. It operates with virtually no particle generation, and the force of the ion burst is easy to modify by adjusting the gas feed pressure (recommended pressure: 15 – 30 psi, depending on distance to target surface).

Emitters are made of corrosion-resistant titanium to ensure a long service life—several years when used with filtered gas supply. Tip replacement requires only seconds and entails no disassembly. Specify an optional in-line capsule filter to ensure the purity of the incoming feed gas.

Standard kit includes a static-controlling Ionizing Blow-Off Gun, 8-foot x 0.25" (2438 mm x 6 mm)-diameter polyethylene gas tubing, a coiled low-voltage power cable, 8 feet (2438 mm) when fully extended, transformer and 0.4-micron in-line filter. Cable attaches to the gun and power transformer by means of telephone-type jacks for fast, easy installation.

Input Pressure vs. Discharge Time

How to Interpret the Chart:

At each of the three test distances, 6", 12" and 24" (152 mm, 305 mm, 610 mm) from the target surface, you can observe an optimal input pressure setting, which corresponds with the lowest discharge time.

Raising the pressure higher than this point results in an increase in the discharge time (the curve swings to the right) because higher pressure drives the ions at the target with too much force, causing uneven dispersal and compromising discharge effectiveness. Lowering the pressure below this point results in too little force; the ions require longer to reach the target and many disperse before discharging the surface.
