EXAIR Displays Benefits of Ion Air Gun Static Eliminators

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.

Gen4 Ion Air Cannon Static Eliminators Used in Tight Spaces

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!

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.

To receive your copy of the Basics of Static Electricity white paper, click the photo above or the link here.

Removing Static From Diaper Absorbent Material

This is where the absorbent material inside a disposable diaper is made

The image above shows one step in the process of disposable diaper manufacturing.  In this step of the process, the absorbent material is ground through a mill on the top of the “bunker” where it falls down a shaft and onto a mesh screen.  Once on the mesh screen, the material is repressed into the proper size and shape for placing into the diapers.

This manufacturer contacted one of our Russian distributors about the application because the milling of the absorbent material was creating static.  This static caused the material to adhere to the walls of the bunker chute and to unevenly distribute onto the mesh.  This unevenness leads to holes in the pressed/shaped absorbent material which translates to a reject rate of ~1 out of every 20 diapers.

An EXAIR Ion Bar

The ideal solution in this case needed to eliminate the static within the chute to allow for proper distribution on the mesh below and proper material placement into the diapers.  An Ion Bar was originally desired by the customer, but material accumulation on the emitter points was a concern so this solution was removed from consideration.

An EXAIR Ion Air Cannon

An Ion Air Cannon, however, was able to provide the desired solution by mounting outside of the chute and feeding a low volume of ionized air to remove the static.  The ionized airflow from the Ion Air Cannon is strong enough to permeate the full volume of the application, but low enough to not disturb the absorbent material within the process. Using an Ion Air Cannon allowed this manufacturer to eliminate defects and wasted materials, increase their throughput, and improve the quality of their products.  Defects dropped from 1/20 diapers to less than 1/1000.

Static Electricity – What is it?

Now that the air is cooling and the humidity is dropping, you may often experience the phenomena of static electricity, and the resultant shock when touching something metal. As a child, you may have learned about static electricity by rubbing a balloon on your head and then seeing it stick to the wall. What is the science behind static electricity?

3864437099_92eb16d611_z

All materials are made up of atoms, which have a positively charged core called the nucleus surrounded by a cloud of negatively charged electrons.  Each material is different, and in some types of materials the positive nucleus has a very strong pull on the electrons while in other materials the pull is very weak.  If we were to put a strong  pull material in contact with a weaker pull material, atoms from the weak pull material will migrate, and when the materials are separated, additional electrons will remain with the strong pull material.  Due to the overall increase in electron quantity, the material becomes negatively charged and the other material becomes positively charged. If the materials are rubbed together, the opportunities for the electron migration increases, and thus more electrons are exchanged.

Electrons build up more easily in dry conditions. When the air has humidity, static build up is less common because a very thin layer of water molecules coat most surfaces, which allows the electrons to move more freely and make most materials conductive and static free.

In some cases, static electricity can be a good thing – laser printers and photocopiers use static electricity to transfer ink from the drum to the paper.  Also, some power plants and chemical factories use static electricity  to remove pollutants in a process that takes place within the smokestack.

But generally when EXAIR gets involved, it is because the static electricity is causing an unwanted build up of static charge that affects a manufacturing process. The results of a static charge imbalance can result in a shock to an operator, materials sticking together, poor print quality, sensor or counter malfunctions, bad surface finish, or any number of other problems.

EXAIR offers systems for total static control, such as the Super Ion Air Knife and Ionizing Bars for wide applications such as paper, film and plastic webs, the Super Ion Air Wipe for narrow, continuously moving materials such as wire, tube, or extrusions.  Also offered are the handheld Ion Air Gun for use on three dimensional parts prior to assembly, packaging painting or finishing. Other options include the Ion Air Cannon for limited space or remote mounting applications, Ion Air Jet for tight spaces and concentrated airflow, and the Ionizing Point to provide close distance and accurate static removal.

Changing of the Seasons

According to The Old Farmer’s Almanac, the Fall Equinox and thus the end of summer occurs tomorrow, September 22, at 10:21 am EDT for us here in Cincinnati, OH.

8573370691_72b155b78f_z-1

Just as the seasons change and the weather goes from warm, humid days to cooler, drier times, we see a change at EXAIR in what challenges our customers face. Telephone calls and online chat topics about overheating electrical enclosures and Cabinet Cooler Systems tend to drop off and invariably the topic of static issues and the EXAIR Static Eliminators solutions take their place.

EXAIR has many available solutions for total static control, whether on a moving web, sheet stock, or three dimensional parts, extrusions or plastics.

Static eliminators with air combine EXAIR engineered airflow products with an ionizing point to eliminate a static charge quickly and at great distances.  Laminar flow air streams make it possible to blow away dirt and debris, and deliver the ionized air to neutralize surface static.  They are ideal for hard to reach places and obstructed surfaces, high speed moving objects, and surfaces with extremely high charges. Some examples are the Super Ion Air Knife, Ion Air Cannon, Ion Air Gun, and the Ion Air Jet.

Static Eliminators

Static eliminators without air may be necessary when even small amounts of air can disrupt the product, such as light weight materials. EXAIR offers two types of ionizers to handle these types of applications.  The Ionizing Bar is ideal for flat materials when the bar can be mounted close to the media.  The Ionizing Point is a good solution for spot neutralization such as in winding or slitting operations where its compact size allows for installation close to the source of the static generation. Both of these products should be mounted within 2″ of the surface they are removing static.

EXAIR’s Ion Air Cannon Static Eliminators

8192_iac_sideview2top (924x1024)
Model 8192 Ion Air Cannon


EXAIR Corporation has introduced a new design for our Ion Air Cannon. The new design is able to perform all of the same functions as our previous model with
the additional features that the product is even more rugged to withstand the rigors of industrial, everyday use in a variety of applications. The Ion Air Cannon performs on bench-top applications, can be mounted to a wall or ceiling, or placed in tight spaces within machinery to eliminate static. 

The New Ion Air Cannon, Model 8192 still has the UL component recognition for the US and Canada. It is also OSHA compliant for dead-end pressures in that it keeps the output pressure well below 30 PSIG when dead ended. Keeping our RoHS compliance was another important factor when putting together the new Ion Air Cannon design parameters. Beyond these compliances, the New Ion Air Cannon is also CE compliant to applicable European directives for safety as well as electromagnetic interference.

With the new design, we have integrated the grounding reference into the high voltage cable so there is now only one connection that must be made at the power supply for the high voltage signal as well as the return path for Earth ground. We have also changed the cable construction to be built using a PVC coated, stainless steel, armored cable to withstand many common hazards, thus protecting the internal conductors as well as providing electrical shielding to maintain CE compliance.

The modular, high voltage, cable assembly is also removable to allow for cleaning and replacement of the solid, stainless steel emitter point to insure problem free operation. The New Ion Air Cannon comes standard with a 5 ft. long, high voltage cable. However, other cable lengths up to 50 ft. are available by request for applications where mounting the Ion Air Cannon remotely from the power supply is necessary.

When powered by Model 7960, dual input voltage, Power Supply, the new, model 8192 Ion Air Cannon remains shockless to operators and incorporates over-current protection by means of an integrated fuse in the power supply as well as a shunting secondary to lower the voltage output to zero volts should the high voltage cable become damaged and cause a shorted condition.

The New Ion Air Cannon will make a substantial addition to any application requiring a flexible static eliminating solution to be mounted and operated by personnel working in packaging, finishing, plastic molding, pre-paint dust removal and many more applications.

Give the New Ion Air Cannon a try. You will be pleased with the fast static decay times and impressed with how easy it can remove static in your application.
