ST1200 Horizontal Ionizing Air Blower
The widest coverage in the range: 140 × 120 cm at 150 to 360 CFM. At 1280 mm long the ST1200 spans a full production line rather than a single station, drawing 40 to 80 W depending on the fan setting.

What the ST1200 Fixes
If any of these is happening at your workstation, the cause is usually a surface charge nobody is measuring.
-
The line is wider than any bench blower
A desktop unit covers 40 × 60 cm and a horizontal unit 60 × 120 cm. At 1280 mm long, the ST1200 covers 140 × 120 cm — a full line width rather than a station.
-
Several blowers are being used to cover one area
Two or three units mounted in a row leave gaps between their coverage and multiply the wiring, the mounting and the maintenance. One wide unit does not.
-
The material charges faster than the air can reach it
At 150 to 360 CFM the ST1200 moves considerably more air than a bench unit, which is what carries ions to material that recharges continuously.
How It Works
Corona discharge produces positive and negative ions along the full 1280 mm length, and the fan carries them across a 140 × 120 cm area. Airflow adjusts from 150 to 360 CFM, drawing 40 to 80 W, with ion balance held at 0 V ±10 V.
The process is self-limiting: once a surface reaches neutral it stops taking up ions. What decides whether it works in practice is whether the airflow actually reaches the charged surface — which is why coverage area, not ion output, is the figure to size a blower on. Verify the result with a static field meter rather than assuming it.

Decay Time — Measured
Measured decay times at three positions along the 1280 mm body, for both positive and negative charge. Even at the ends of a unit this long, decay stays within about 0.4 seconds of the centre at 900 mm.
| Position | 300 mm | 600 mm | 900 mm |
|---|---|---|---|
| Left, positive | 0.9 s | 2.1 s | 2.9 s |
| Left, negative | 1.1 s | 2.1 s | 3.3 s |
| Centre, positive | 0.9 s | 1.6 s | 2.0 s |
| Centre, negative | 1.1 s | 1.9 s | 2.5 s |
| Right, positive | 0.9 s | 1.8 s | 2.5 s |
| Right, negative | 1.1 s | 2.1 s | 2.9 s |
Charge decay measured from 1 kV to 100 V, unit running on 110/220 V, ambient 22 °C.
Negative charge consistently takes slightly longer to clear than positive — about 0.2 seconds at 300 mm, widening to roughly 0.5 seconds at 900 mm. Size the mounting height on the slower of the two figures, not the faster.

Where It Goes
A blower neutralizes an area rather than a line. At 1280 mm the ST1200 can be suspended over the work or laid flat on the bench. These are the positions it is sized for.
Full-width production lines
Where the charged area is a line rather than a station, and several bench units would leave gaps.
Optical film and display panels
Large-format material where a single particle is a visible defect and the whole surface has to be neutral.
Industrial packing stations
Wide packing and palletising areas where charged film and board attract contamination.
Bar or Blower, and Which Blower
Use an ionizing bar when the material moves past a fixed point — off a roller, out of a tool, off a stack. A bar mounted at that point neutralizes faster and holds a tighter balance, and is cut to the exact width of the material. Use a blower when the charge sits on a fixed area, or when there is no way to mount a bar within its 1 m working range.
Between the blowers it is a question of area: ST-S200 450 × 450 mm to build into a machine, ST101A 40 × 60 cm for one position, ST104A 60 × 120 cm for a wider bench, and ST1200 140 × 120 cm across a full line.
Frequently Asked Questions
What area does the ST1200 cover?
140 × 120 cm — the widest in the range, sized for a full line rather than a single station.
How much airflow does it deliver?
150 to 360 CFM, adjustable, drawing 40 to 80 W.
What ion balance does it hold?
0 V ±10 V.
How long is the unit?
1280 mm, weighing 14.5 kg — it is mounted over the line rather than stood on a bench.
What power supply does it need?
110 V / 60 Hz or 220 V / 50 Hz.
Should I use the ST1200 or ionizing bars?
If the material moves past a fixed point — off a roller, out of a tool, off a stack — bars mounted at that point will be faster and tighter, and can be cut to the exact width. The ST1200 is for a wide area that has to be neutralized as a whole, or where bars cannot be mounted close enough.
ST101A, ST104A or ST1200?
The ST101A covers 40 × 60 cm for one position, the ST104A 60 × 120 cm for a wider bench or two operators, and the ST1200 140 × 120 cm across a full line.
How fast does the ST1200 neutralize?
At the centre, 1 kV falls to 100 V in about 0.9 seconds at 300 mm, 1.6 seconds at 600 mm and 2.0 seconds at 900 mm for positive charge, tested at 22 °C. At the ends of the 1280 mm body the same measurement takes about 2.9 seconds at 900 mm.
