Static charge is an unavoidable “by-product” of just about any operation that involves the moving of, and/or the contact & separation of, non-conductive materials. This charge is caused by a physical phenomenon known as the triboelectric effect, by which the surface of a non-conductive material becomes electrically charged by coming into contact with another non-conductive material’s surface. Some materials tend to generate a more positive charge, meaning their molecules are prone to losing electrons to the molecules on the other surface, while others tend to generate a more negative charge – meaning their molecules are prone to gaining electrons from the other surface. These are the materials found at either end of a triboelectric series chart, like this one:
Wherever a non-conductive material is located in the triboelectric series, the solution to removing the static charge is to provide an ample supply of ions (either positively or negatively charged) to attract – or offer – electrons to neutralize that charge. And that’s exactly what EXAIR Gen4 Static Eliminator Products, like the Super Ion Air Knife, do.
EXAIR Gen4 Super Ion Air Knives generate a laminar, controllable curtain of ionized air, and come in lengths from 3 inches to 9 feet. Like any of our Air Knife products, they can be easily installed & positioned with our Universal Air Knife Mounting Systems. Plumbing Kits, simplifying the supply of compressed air and are especially beneficial with longer lengths. They’re capable of dissipating a 5kV static charge in as little as 0.18 seconds, so they’re ideal for fast moving sheets & films. The armored & shielded high voltage cable resists cuts and abrasion.
If you have compressed air, and problems with static, the EXAIR Gen4 Super Ion Air Knife could very well be the solution you’re looking for. Depending on the size and shape of the ionized air flow required, we may also consider a Super Ion Air Wipe, Ion Air Cannon, Ion Air Jet, or if a handheld solution is desired, an Ion Air Gun. If you’d like to discuss your issues with static charge, give me a call.
