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.

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

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.

Video Tutorial on Cleaning the Gen4 Static Eliminator

It has been over two years since EXAIR first brought our Gen4 Static Eliminators to market with improved performance, materials and durability.  The new design features continue to provide our customers with reliable, rugged and problem solving static eliminators.

More recently our Gen4 product line was completed by integrating these same beneficial features in the Gen4 Ionizing Bars, Gen4 Super Ion Air Knives, and Gen4 Standard Ion Air Knives.

There are two common ways that a Static Eliminator will start to underperform; contamination buildup and point degradation.  To create ions from a metal point, a high voltage is needed.  With 5,000 volts forcing its way into a confined area, the energy behind making an ion creates a corona field.  Any contamination near or around that point will produce a small amount of charred material.  The more contamination in the surrounding area, the faster the buildup will occur. Once a sharp point is coated, the ion production begins to decrease.

The other issue is with metal point degradation.  With the cycle of heating and cooling, the material will start to lose the sharpness of the point over time.  Like a wick used in a candle, you lose a little bit each time.  For both methods above, once the point sharpness is reduced, the dissipation time to remove static starts to increase.

For any “forensics” analysis with the Static Eliminators, you should have a model 7905 Static Meter.  Besides viewing the ion points, the Static Meter can help determine the severity of the function of the ion points.  If cleaning is required, you can use a soft-bristled brush to remove any charred contamination from the point and the base area.  Make sure that the power is turned off before cleaning.  For resistor-based Static Eliminators, the metal ion pins are replaceable.  This is model 901188.  This added feature makes a cost-effective way to keeping the points sharp, and the Static Eliminators like new.  The video below shows how to clean and replace the ion points.

Contact any of our Application Engineers if you have any additional questions about cleaning, about a new application or about potential solutions to static related problems.

A Tale of Two Super Ion Air Knives

A manufacturer of plastic bottles had a problem with static charge. Right after the bottles are extruded and cooled, they have an apparatus that “unscrambles” them and places them, single file, onto a conveyor. It does so with some fabric belts and plastic rollers. If you know anything of static electricity, dear reader, you probably recognize that there aren’t too many better ways to generate a static charge than to rub plastic against plastic, or (even worse) plastic & fabric together.  Here’s a prime example of the kind of static charge you can get, just from unrolling plastic film.

The separation of the non-conductive surfaces (like when this plastic film is unrolled) is capable of generating an incredible amount of static charge.

Now, the bottle makers didn’t have a static meter, but they didn’t need one to know they had issues:  the bottles that the “unscrambler” was putting on the belt were still very much “scrambled.”  They installed a Model 112209 9″ GEN4 Super Ion Air Knife Kit, to blow ionized air up from under the bottles as they entered the belt conveyor, and they did see what they’d call an improvement, but not quite what they’d call a solution.

Unfortunately, dissipating the static from just about half of the surface area of the bottle was still leaving them with half a problem.  However, by adding a Model 112009 9″ GEN4 Super Ion Air Knife (the 112209 Kit’s Power Supply has two outlets, and its Filter Separator & Pressure Regulator are capable of handling the flow to two 9″ Air Knives,) they were able to blow ionized air down from the other side, and up from where the first one was installed.  A soft “breeze” was all it took…a stronger air flow would have worked against the “unscrambler” anyway…because even at very low supply pressures, the Super Ion Air Knives produce an extremely fast static dissipation rate.

Even with a 5psig supply…which makes for just a “whisper” of air flow, the EXAIR GEN4 Super Ion Air Knife eliminates a 5kV charge in under half a second.

If you’ve got problems with static charge, we’ve not only got improvements; we’ve got solutions. Give me a call to find out how we can help.

Basics of Static Electricity

Here in the Northern Hemisphere, we are in the middle of winter and that means extremely dry air, and frequent shocks when reaching for a door knob after walking across a carpeted surface.  While a shock is mildly uncomfortable and can be annoying to us, the presence of static electricity in an industrial manufacturing process can be much more problematic.

Problems that static cause range from operator discomfort to increased downtime to quality issues.  Dust can cling to product, product can cling to itself, rollers, frames, or conveyors. Materials may tear, jam, curl and sheet fed items can stick and mis-feed. Hazardous sparks and shocks can occur, possibly damaging sensitive electronics.

EXAIR has put together a useful tool, the Basics of Static Electricity white paper with Interactive Regions to help a person learn more about static.

Basics of Static Electricity

 

Topics covered include Electron Theory, Causes of Static Electricity, Triboelectric Series chart, and Types of Static Generation.  Also, the white paper covers the areas of How to Control Static Charge Buildup, Determining the Source of the Static Buildup, Eliminating or Minimizing the Source Causing the Buildup, and Treating Static Buildup.

The Treating Static Buildup is a comprehensive review of the EXAIR Static Elimination products and how each technology is best applied to different processes and applications.

Stretch Wrap Static Solution

Recently a customer called in to EXAIR to discuss a static issue in a stretch wrap process in the plant. Stretch wrap is a highly stretchable plastic film.  The elastic recovery keeps the wrapped load tightly bound. The most common stretch wrap material is a linear low-density polyethylene or LLDPE.  The combination of the stretching of the plastic film and the sliding of the film on the cardboard boxes as it is being wrapped causes a build up of static. This static can cause serious havoc and issues in the process including personnel shocks, zapping counters and other sensors causing failures, and preventing marking systems from delivering good information on to the stratch wrap.

Stretch Wrap Operation

The discussion started with minimum and maximum load sizes and how to design a system that would work with all configurations and be as flexible as possible.  We spoke of dimensions and where we could we could mount on 3 sides, and so forth.

Then came the question that we invariably get to and that is ‘what issue does the static cause and how does it affect the rest of the process?’  The answer here simple, ‘an operator has to write a code number on the side and affix a label, and in doing so, receives a shock.’ When it was determined that only a small section of one side of the load needed to be treated, the solution was simple.  We proposed an 18″ Ionizing Bar and Power Supply. Because the machine had a fixed datum, all loads would pass within 1-2″ of a vertically installed Ionizing Bar, so no adjustment is needed for different load sizes.

The Ionizing Bar quickly dissipates a strong static charge as shown in the chart below.
