Industrial Static Eliminators, Ionizing Bars and Air Blowers

An anti static bar — also called an ionizing bar, ionizer bar, static eliminator bar, static control bar, or ionising bar in British English — removes static electricity from material surfaces by delivering balanced positive and negative ions. Grounding drains static charges from conductors; an anti static bar is what you use on insulators such as plastic film, polarizer sheets, PCB laminate, packaging webs, and moulded parts that cannot be grounded directly.

A static eliminator applies high voltage to a row of emitter points, ionizing the surrounding air by corona discharge. Positive and negative ions drift toward the oppositely charged surface until its voltage falls toward zero. The process is self-limiting: once the surface reaches neutral, ion uptake stops. Shidike bars are rated 6.5 kV pulse output at 12 W. How that pulse is applied differs by series — pulsed AC on the ST-G, pulsed DC on the ST-E and the ST-F — and ion balance is ±50 V on the ST-G, the tightest in the range.

An industrial static eliminator generates balanced positive and negative ions that neutralize electrostatic charge on insulating materials and production surfaces that cannot be grounded directly.

Use an ionizing bar for wide or continuously moving targets such as conveyors, films, sheets, and web lines. Use an ion blower or fan when ionized airflow must reach a workstation, enclosure, or target positioned farther away.

Provide the material, charged area width, line speed, installation distance, measured voltage, available mounting space, environment, and required machine-control signals.

Inspect and clean emitter points at intervals based on the contamination level, confirm grounding, and verify neutralization performance with a suitable static field meter or charged plate monitor.

There is no difference. Anti static bar, ionizing bar, ionizer bar, static eliminator bar, and static control bar all describe the same device. Regional and industry habit decides which term is used.

Shidike bars are rated 6.5 kV pulse output, generated inside the bar from a DC 24 V supply at 12 W — that figure is the high voltage reaching the emitter pins, not the supply you wire up. How the pulse is applied differs by series: pulsed AC on the ST-G, pulsed DC on the ST-E and the ST-F. Ion balance is a separate figure — ±50 V on the ST-G, ±80 V on the ST-E, ±100 V on the ST-F — and it describes the offset of the bar itself, not the residual surface voltage left on your material, which your process defines.

Anywhere from 30 mm to 1000 mm — the same working range on all three bar series. Closer mounting speeds up neutralization; the 1 m upper limit is what lets one bar cover a gantry or an overhead position where a closer mount is impossible.

Yes. Bar-type static eliminators are used in display, optical film, semiconductor, and PCB cleanrooms. Confirm the required cleanliness class and the mounting method before selecting a model.

The ST-G, ST-E and ST-F bars operate without compressed air. Air-assisted models are available where the target sits beyond the 1 m working range.

Electronics, PCB and SMT assembly; optical film, polarizer, LCD, OLED and display manufacturing; packaging, printing, labelling and converting lines; plastics, injection moulding and rubber processing; and textile, nonwoven, lithium battery and photovoltaic production. Any process handling an insulating material at speed will build a charge that has to be neutralized.

Yes. Uncontrolled electrostatic discharge damages components on SMT and PCB assembly lines, and electrostatic attraction pulls dust back onto surfaces that have just been cleaned. Neutralizing the surface charge removes the cause of both. Verify the result with a static field meter or charged plate monitor rather than assuming it.

An anti static blower carries ions to the target on moving air, so it reaches farther and suits workstations, enclosed machines, and irregular parts. An ionizing bar mounts close to the material and neutralizes across a fixed span, which suits conveyors, films, sheets, and web lines.

Shidike anti static blowers range from 45 to 360 CFM. The ST101A covers 40 by 60 cm at a workstation, the ST104A covers 60 by 120 cm, and the ST1200 covers 140 by 120 cm for wide lines. The ST-S200 mini ionizer reaches 150 to 450 mm.
