I had a headache the other day. Of all the things that can make me grumpy, nothing makes me grumpier than a headache. Luckily, there are over the counter medications that work quite well, and quickly, to boot. And I had a brand new bottle of them in the cabinet.
When I opened the package and removed the tamper-resistant plastic band on the cap, it stuck to my hand when I went to drop it in the trash can. This raised my grumpiness just a touch. I shook my hand to try and get it off, and it fell behind the trash can. My grumpiness elevated a bit further. I hit my head (you know, the one I was trying to cure the pain in?) on the counter while bending over to retrieve it. That activated my grumpiness alarm, which sounds just like mild profanity. My wife silenced that alarm pretty quickly.
The plastic band stuck to my hand, of course, because it’s made of a non-conductive material, and peeling it from the bottle cap, which is also a non-conductive material, generated a static charge. As a subject matter expert on the topic of static elimination, I am quite familiar with the phenomenon, the problems it causes, and, more importantly, the numerous ways to apply solutions to those problems:
One such solution was related to my problem with the tamper-resistant seal. A mouthwash manufacturer was actually having trouble getting those seals ONTO the bottles on their packaging line. The bottle caps themselves had so much static charge on them that they repelled the seal as the machine tried to drop it in place before heat shrinking it. An Ion Air Jet solved the problem:
Speaking of plastic bottles, the finishing process after extrusion can leave small bits of plastic particulate behind, and static charge can keep them on the bottle. This was a great fit for an Ion Air Cannon:
Sometimes, air flow isn’t necessary, like in the case of a film that is eventually made into single-use condiment packages, with a static charge that was high enough to fry the print heads that apply the label text. An Ionizing Bar protects those print heads:
EXAIR Corporation’s Gen4 Static Eliminator product line offers a wide variety of options for total static control. If you need to get rid of nuisance shocks, clinging dust, tearing, jamming or curling of material, misfeeding sheets or rolls, or any of the numerous other problems that static charge can cause, give me a call.

It’s bitter cold this week in southwest Ohio, and one of the consequences of that is dry air in heated indoor areas. If you’ve walked across a carpeted floor and pet your cat (like I did the other day), you (and your cat) may have experienced a phenomenon known as dissipation of static electricity.
The relatively low static charge you pick up by shuffling your socks across the rug is pretty small, compared to the charge generated by:
High speed rolling & unrolling of plastic film on a shrink wrapper.
Plastic pellets traveling through a conveyor system to an injection molding machine.
Slitting or trimming of paper, laminates, sheets, etc.
Removing protective layers between sheets of delicate materials.
And these can cause issues year-round. The problems associated with static charge in these situations include:
Nuisance shocks to operators.
Dust and debris clinging to product finishes and surfaces
Product clumping or clinging while in transit.
Thin sheets tearing, jamming, folding, or misfeeding.
Disruption of sensitive electronic sensors, switches, etc.
EXAIR Corporation has a variety of Static Eliminator Product solutions, depending on the specific needs of a particular application. To answer the question in the title of this blog, though, the Gen4 Ion Air Cannon is quite versatile, and is often considered alongside our other products. For example:
Gen4 Super Ion Air Knives come in lengths from 3 inches to 9 feet. If you have a wide web, sheet, or plate to remove static charge from, they’re the best choice, hands down. For narrower widths, or situations where you have to blow in from the side or at a certain angle due to physical interference, the Gen4 Ion Air Cannon’s small footprint and adjustable mounting bracket provide a great workaround.
Gen4 Ion Air Jets generate a focused, concentrated flow of ionized air, for spot cleaning of smaller parts. Its compact design is ideal for installations in close quarters. If you have some room, the Gen4 Ion Air Cannon actually uses less compressed air to generate a higher ionized air flow…and it’s quieter, to boot.
Gen4 Super Ion Air Wipes are made to blow off and remove static from pipe, cable, extruded shapes, etc. They come in 2″ or 4″ diameters. If your product is larger than that, an array of Gen4 Ion Air Cannons can accommodate that.
Gen4 Ionizing Points are often installed in ducts to ionize existing air flow. Arrays of two, three, or four are suitable for ducts up to about 6″ in diameter, depending on the air flow rate. For larger ducts (or very high flow rates,) Gen4 Ion Air Cannons can be installed to blow into a ‘Y’ connection in duct walls.
These are just a few of the myriad Static Eliminator applications that EXAIR Corporation has successfully solved over the years. Many times, the details of the application make one particular product the clear choice. When there ends up being more than one worth consideration, one of the others is usually the Gen4 Ion Air Cannon.
Again…that’s based on the details of the application, and we’re here to help with that. If you’ve got a static problem, give me a call.

In the fall and winter seasons, the air becomes much drier. You may be familiar with the unpleasant shock you get from the door knob after walking across a carpeted surface. While this type of shock doesn’t generally cause any sort of problems, in many industrial processes this static electricity can cause a wide range of issues. These may manifest as nuisance shocks to an operator – similar to the door knob example, but it can also cause problems with the finish quality of coatings and paint. It will make ink jetted codes unreadable, cause blemishes in printing processes, and short out sensors being relied upon for counts and quality inspections…just to name a few.
The reason that you experience static shocks more frequently during winter is due to the relative humidity. At colder temperatures air does not hold as much water as it does when it’s warm, and since water conducts electricity, higher humidity keeps static at lower levels. Even though you’re heating your house to a similar temperature, the air that is being drawn into your home and heated is still the dry cold air containing less moisture.
So how do we tackle this static problem that’s running rampant in your processes? EXAIR has a wide range of Static Eliminators available to ship same-day from stock. Each of which is designed to handle different types of applications. At the heart of these Static Eliminators is the EXAIR Power Supply. Available with either 2 or 4 ports, the Gen4 Power Supply is suitable for use with either 115V or 230V via the selector switch on the back. A 6’ modular power cord and lighted power switch are included. The modular cable protects sensitive electronics against electromagnetic interference while easing connections and routing. An integrated fuse (spare fuse is also included) on the primary protects against voltage spikes.
Two shielded cables are included with both styles of Power Supply. A standard 3-prong outlet for North American customers, and another that allows you to install your own plug to accommodate any style of electrical outlet. The integrated ground connection on the high voltage side allows for complete connection using just the bayonet connector. A grounding post on the front-face of the Power Supply is available for bonding of the Power Supply to machine frames. Shunting circuitry designed into the Power Supply protects the user against any short circuit on the secondary side.
The Power Supply includes an integrated flange for easy mounting in any orientation. Rugged and durable stainless steel connections are present at the high voltage side vs the plastic connectors of the competition. This facilitates the integrated ground and shockless design of all of our Static Eliminator products. The Power Supply is both RoHS and CE compliant, as well as UR Listed.
Here at EXAIR we’ve helped customers in a wide range of industries solve their static issues within their processes.
