EXAIR’s Gen4 Static Eliminators Product Line

In the winter, as the temperature gets colder and colder and the air is getting drier and drier, static becomes a larger problem. In the summer, water in the air can help dissipate the electrons that we pick up as we move around, but when the air is drier, the static charge collects and clings to surfaces, building up until… zap! This can be a huge problem for companies as static can cause products to bunch up and not process correctly. Or even worse static can build so much it can shock electrical devices causing costly repairs and downtime. That’s why EXAIR has a full catalog of static eliminating products, and we will talk about them and what each product is best suited for!

Gen4 Static Eliminators

The most popular Static Eliminator we sell is our Gen4 Super Ion Air Knife! By combining a Gen4 Ionizing Bar with a Super Air Knife, The Gen4 Super Ion Air Knife provides rapid static elimination AND blows off any dust, chips, or debris that was being statically held to the surface.  The laminar curtain of ionized air not only maximizes the rate of static dissipation, but is also ideal for stripping/sweeping away any debris, leaving a clean, static-free surface.  No more jamming, tearing, nuisance shocks to operators, dust attraction, or any of the other host of problems associated with static electricity.

EXAIR’s Gen4 Super Ion Air Wipe provides a uniform 360° ionized airstream that is simple to clamp around a part for reducing static electricity and cleaning contaminants. It is great for use on pipe, cable, extruded shapes, hose, wire and much more. We offer the Gen4 Super Ion Air Wipe in either 2” or 4” inner diameter, it is powered by compressed air and an external power supply. The Gen4 Super Ion Air Wipe generates both positive and negative ions that are transmitted the emitter points located on the i.d. of the wipe. Since static charges can be either negative or positive it is easy to eliminate both states of charge due to the mixed polarity of ions being generated.

To put it simple the Gen4 Ion Air Cannon is based on the mechanics of the 2″ diameter Super Air Amplifier with added static reduction capabilities and as its name implies it amplifies the supply air up to 25 times! This highly engineered product is very effective at cleaning product and reducing static at distances of up to 15′ away.

EXAIR’s Gen4 IoAir Jet is a compact ionizer that is capable of delivering a concentrated ionized airflow that will cover a precise spot without disturbing the rest of the process. The quiet, focused air stream can quickly eliminate the static charge on surfaces. At a pressure of 80 psig the Gen4 Ion Air Jet is capable of dissipating a 5kV charge in .18 seconds!

In addition to providing rapid static decay, the Gen4 Ion Air Jet also helps to minimize compressed air use while maximizing the ionizing airflow. Utilizing a specially designed shim, the Gen4 Ion Air Jet entrains ambient air at a rate of 5:1. The airflow can easily be adjusted from a forceful blast to a gentle breeze simply by increasing or decreasing the inlet pressure to the ionizer.

You can also get the Gen4 Ion Air Jet in a handheld gun option, this is called our Gen4 Ion Air Gun. This is great for applications where your operator is doing the static elimination and blow several times a shift by hand.

Static Solution in the Printing Industry

When the weather gets dry and cool, static can be generated very easily, and it can become a real nuisance.  For the printing industry, static forces can pull or push the ink droplets which can create poor print quality like “ghost” images.  Static can also cause contamination to “stick” to the surface of the sheets affecting the printing process.  This can slow production, generate high scrap rates, and allow for poor quality.  In this blog, I will share the details about a printing company having static problems and a simple solution with a Gen4 Static Eliminator.

For this printing company, static was causing issues in print quality on their polypropylene sheets. Polypropylene is a non-conductive material which can generate high amounts of static that can cause many issues.  Their manual operation of moving, sliding, and picking up of the polypropylene sheets was generating the static.  Now that we found the cause, I had to determine a solution.

They sent pictures to describe the process in more detail.  An operator would pick up a sheet with the dimensions of 3 feet wide by 5 feet long (0.9 meters by 1.5 meters) from a bin.  He or she would load three polypropylene sheets onto a wide vacuum table next to the printing machine.  The table had an indicating bar which used yellow/green lights to align each sheet.  Once the indicator lights turned green, this meant that the sheet was aligned properly, and the operator would then hit a switch.

A dual rail with vacuum cups would come over and “grab” the three sheets.  The vacuum rail would pull the new sheets onto a sliding platform at the same time removing the printed sheets into a stacking area.  With the new sheets, this sliding platform would travel into the print machine where the print head would create the images.

Once the printing was completed, the sliding platform would come back to the original position where the process would repeat itself.  With all the handling and moving of the polypropylene sheets, static was being generated.  To improve their printing process by removing the static, we had to target an area where we would not have to worry about static regenerating.

EXAIR is a leading manufacturer of Static Eliminators, and we had a good discussion in solving his issue.  Ideally, we want to place the Static Eliminator just before the printing process.  In this application.  I recommended to them to locate a Gen4 Ionizing Bar just behind the indicating bar.  This would remove any static as the sheets were going onto the sliding platform.  Since the sheets were 3 feet (0.9 meters) wide, we needed to cover a span of 9 feet (2.7 meters) total.  Believe it or not, EXAIR manufactures and stocks an Ionizing Bar this long!!!

For this customer, they would not have to worry about any stop gaps in coverage with a single length product.  Also, the profile for the Gen4 Ionizing Bar is very thin and would not interfere with the vacuum rail system.  So, when the vacuum rail picks up the polypropylene sheets, the Gen4 Ionizing Bar will be able to remove the static from the printable surface.

Gen4 Ionizing Bar with 7960 Power Supply

I recommended the model 80108 Gen4 Ionizing Bar with the model 7960 Gen4 Power Supply.  This model can emit ions that can cover a span of 108 inches (2.73 meters).  The Gen4 Power Supply, which generates a 5,000 Volt signal, connects to the Gen4 Ionizing Bar with an electromagnetically shielded durable cable.  The alternating current generated by the Power Supply allows for the creation of both positive and negative ions from each point.  This will ensure neutralization of any type of static.

The Ionizing Bar can be positioned between 0.5” (13mm) to 2” (51mm) from the sheet surface to optimize decay rates.  After they mounted and started using the Ionization Bar, the static was removed quickly, and the printing issues were eliminated.  With a quick and simple set up of the Gen4 Ionizing Bar, they were able to get back on track with great quality and fast productivity.

If you have static issues with your printing process, you can contact an Application Engineer at EXAIR.  We will be happy to make your static issues disappear and your vibrant images reappear.

The Case for The Ion Air Gun to Eliminate Static

EXAIR manufactures a range of Static Eliminator products that are all efficient, effective, and easy to use…none more so than the Gen4 Ion Air Gun. Consider:

  • It’s “plug and play,” all the way.  Connect the cable to the Power Supply, and hook it up to your compressed air system, and you’re ready to go.
  • It’s efficient and quiet.  The high velocity jet entrains an enormous amount of air from the surrounding environment, where it’s ionized and ready to eliminate static charge quickly and effectively.
  • Instant static dissipation, at your fingertips (literally) – squeeze the trigger to blow ionized air, anywhere you want (well, within the reach of the 10 foot cable, anyway.)
Model 8493 Gen4 Ion Air Gun Kit comes with everything you need, right out of the box. Just add compressed air.

Again, the Gen4 Ion Air Gun is just one of our Static Eliminator products.  How do you know if it’s the right one?  The selection of many EXAIR Intelligent Compressed Air Products comes down to the size & shape of the air flow that will solve the application.  Static Eliminators are no different.

  • If you need to treat a large surface, you might be looking for a Gen4 Super Ion Air Knife.  They come in lengths from 3 inches to 9 feet long, and blow a laminar, even curtain of ionized air that’s extremely effective and fast at static elimination, even at very low supply pressures.
  • Gen4 Super Ion Air Wipes blow a 360° ionized airstream for pipes, cables, extruded shapes, etc.
  • Gen4 Ion Air Cannons and Gen4 Ion Air Jets are made to mount in place, and blow a focused, conical flow of ionized air.

If you’ve got large areas, multiple surfaces, or complex geometries to contend with, one (or an array) of these products might be the solution.  For a simple, straightforward, hand held static elimination solution, though, it just doesn’t get any easier than the EXAIR Gen4 Ion Air Gun.  Call me to find out how you can get one today.

Eliminate Static in Tight Spaces with EXAIR’s Gen4 Ion Air Cannon

The lower relative humidity associated with the cold, dry air of winter results in a significant increase in calls related to static problems. Luckily, EXAIR has a wide-range of Static Eliminators that are designed specifically to address static issues in a variety of industries. Materials such as paper, plastic, or textiles will normally contain an equal number of both positive and negative ions. When subjected to friction, this balance can be disturbed if the atoms gain or lose an electron. This gaining/losing of an electron causes the atom to be electrically imbalanced.

The static charge will then exert a force on nearby charged objects or grounded conductors (including personnel). These issues can also manifest in the form of dust clinging to product, product clinging to itself, rollers, machine beds or frames, materials jamming, and sheet feeding problems. Our Gen4 Static Eliminators have undergone independent laboratory tests to certify that they meet the rigorous safety, health, and environmental standards of the USA, European Union and Canada that are required to attain the CE and UL marks.

One of these such products is the Gen4 Ion Air Cannon. EXAIR’s Gen4 Ion Air Cannon neutralizes static charges at distances up to 15 feet without any moving parts. Utilizing EXAIR’s 2” Super Air Amplifier, the Ion Air Cannon will maximize ionized airflow while minimizing compressed air consumption. The strong, concentrated, quiet, and efficient ionized air is capable of eliminating a 5kV charge in as little as .37 seconds.

The compact design saves space and allows it to be mounted in confined areas on walls, machine frames, bench tops, etc. The stand is pre-drilled for easy mounting, and incorporates a swivel adjustment to precisely position the airflow. Some examples of applications that have required the assistance of an Ion Air Cannon include: removing static from motorcycle bodies prior to painting, static removal on PCB boards, and disposable diaper manufacturing.

With a wide variety of Static Eliminating products available from stock, don’t wait for your static problems to subside when humidity levels come back up in the spring. Get yourself a Gen4 Static Eliminator from EXAIR and make sure you’re able to operate, static-free, for the rest of this winter and in the subsequent seasons to come!

The Simplicity Of EXAIR Static Eliminator Systems

If you’re a regular reader of EXAIR Application Engineering blogs, you’ll likely recognize the words “easy to do business with.” And if you’re an EXAIR customer, you’ve likely found that to be true – from customer service, to technical support, to shipping your order – and, of course, the product itself.  We get calls, from time to time, asking about what kind of “engineering system design” services we offer…and the simple answer is, it’s already been included in the product itself.  Most of the time, installation of an EXAIR Intelligent Compressed Air Product requires basic hand tools, and a compressed air supply.

One exception to this is our Static Eliminators product line: they also require electricity.  Good news is, the “engineering system design” is included for these products as well, in the Power Supply.  Gen4 Static Eliminator Power Supplies are energized by either 115VAC or 230VAC.  Cables for both are provided; the 115VAC three-prong grounded plug being the most common…just plug it in to any grounded wall outlet, and you’re in business.

Connecting EXAIR Gen4 Static Eliminators to the Power Supply is just as easy.  All of our Gen4 Static Eliminator Products have a 5ft (1.52m) cable (except the Ion Air Gun…it’s got a 10ft, or 3.04m cable) with a bayonet end for easy, safe, and reliable connection to the Power Supply.  The Model 7960 Gen4 Power Supply has two ports, which can accommodate any two Gen4 Static Eliminators.  This is often quite convenient…for example, Super Ion Air Knives are commonly used in pairs, to eliminate static on both sides of a sheet or film.

Some applications, though, call for more than two Static Eliminators.  For instance, Ionizing Points, Ion Air Cannons, and Ion Air Jets installed in an array to provide static elimination in a duct, or to multiple surfaces on an extrusion or part.  The Model 7961 Gen4 Power Supply has four ports, to fit these situations.

All EXAIR Gen4 Static Eliminators use one of two Power Supplies – your choice of the 2-port Model 7960, or the 4-port Model 7961.

Occasionally, a Static Eliminator needs to be installed in such a way that its 5ft (1.52m) cable cannot reach the desired location of the Power Supply, or an Ion Air Gun needs a longer cable to get everywhere in the space it’s being used in.  Or sometimes, a 5ft cable is simply too long.  To meet those needs, our shop can make custom length cables, precisely to any length you require, up to 50ft (15.2m) in length, for any Static Eliminator.  The only limitation, “engineering system design”-wise is 100ft (30.4m) of total cable length from any one Power Supply.

When Static Eliminators (like these two Ion Air Cannons) are used on a mobile platform (like this one, where they facilitate separation of plastic plates in a solar panel plant,) custom length cables can be necessary to reach a common Power Supply.

Static electricity is responsible for a multitude of problems from dust clinging to material, to material clinging to itself, to jamming, misfeeding, tearing & curling of product, and last but certainly not least, painful shocks.  If you’ve got a static problem you want to get rid of in a hurry, give me a call.  We’ve got a solution for you, ready to go, right out of the box.

The Wonders of The Gen4 Super Ion Air Knife

The Gen4 Super Ion Air Knife is a powerful static eliminator that prevents jamming, tearing, shocks and dust build up by neutralizing static and blowing away the debris.

The Gen4 Super Ion Air Knife combines the quiet and efficient Super Air Knife with the compact design of the rugged Gen4 Ionizing Bar resulting in a total solution to remove static electricity from plastics, webs, sheet stock and other product surfaces. Removing the static helps reduce or eliminate the process issues that the static electric causes, allowing for greater production speeds, improved product quality and a cleaner product.

The Gen4 Super Ion Air Knife floods an area or surface with static eliminating ions. With a uniform airflow across its length, misalignment to critical surfaces like webs is avoided.  The force can be adjusted from a light breeze, to a full out blast of air. The Gen4 Super Ion Air Knife is electrically powered, is shockless and has no moving parts.

How It Works

gen4siak_hwrks_800x
How The Gen4 Super Ion Air Knife Works

In the diagram above, compressed air flows through an inlet (1) into the plenum chamber of the Gen4 Super Ion Air Knife. The flow is directed to a precise, slotted orifice. As the primary airflow exits, it creates a uniform sheet of air across the entire length, pulling in in surrounding air (2). An electrically powered Gen4 Ionizing Bar (3) fills the curtain of air with positive and negative charges. The air stream delivers the static eliminating ions to the product surface (4) where it instantly neutralizes static and cleans off dust and other particulates.

The Gen4 Super Ion Air Knives are powerful tools, and very quickly dissipates 5kV of static even at low compressed air supply pressures. At 5 PSIG, only 3.7 SCFM (0.3 BAR, only 105 SLPM) of compressed air per foot of length is required!!  Sound levels are also very low, resulting in quiet operation.
