EXAIR Ion Air Jets: Focused, Hands Free Static Removal

Hand held convenience of the Ion Air Gun (easy) or no-hands convenience of the Ion Air Jet Station (easier.) Your call.

Static electricity can cause jamming of machines, misalignments, collection of dirt and debris, and shock hazards to personnel.  EXAIR manufactures a variety of Static Eliminators to remove this common nuisance.  In this blog, I will examine our most versatile product within the Static Eliminators; the Gen4 Ion Air Jets.

The Gen4 Ion Air Jets are a modification to the EXAIR Air Jets.  The Air Jets create a high velocity air stream along an engineered Coanda profile.  The profile creates a low pressure at the entrance of the Air Jet to draw in ambient air.  This makes the Air Jet very efficient as the output flow is more ambient air than compressed air. Also, with the engineered design, we are able to create a laminar air stream to carry the ions to the target up to 15 feet (4.5 meters) away.

The ions are generated at the exit of the Air Jet by an ionizing point.  This ionizer can create a large amount of positive and negative ions.  This allows for two things to occur.  We are able to eliminate any type of static charge, and we can establish a fast decay rate.  The emitter point inside the Gen4 Ion Air Jet is replaceable in order to keep the point clean and sharp.  What operates the Gen4 Ion Air Jet is the Gen4 Power Supply.  It is the “engine” behind the ion generation.  EXAIR offers two types.  The model 7960 has two output ports and the model 7961 has four output ports to operate multiple units.  They have a selectable input voltage to use 115Vac or 230Vac.  The high voltage cable between the power supply and the Gen4 Ion Air Jet is an armored cable to resist cuts and wear.  It has an integrated ground and is electromagnetically shielded.  Together, you get a compact powerful unit that can remove static quickly for spot blowing and cleaning.

Overall, the operation of the Gen4 Ion Air Jet is similar to the Gen4 Ion Air Gun, but with the Ion Air Jet, it is mainly used for “hands-free” operations.  With a small amount of compressed air, the unit can “shoot” the ions onto small surfaces and areas.  They are very quiet, and they meet the OSHA requirements for dead-end pressure and noise allowance.  They are very easy to control with a regulator to adjust the flow from a breeze to a blast.  The design of the ionizing point is shockless and does not use any radioactive materials.  This compact, low-cost unit can be utilized for neutralizing static and cleaning three-dimensional parts, screen printing, glass lenses, shrink bands and much more.

As I mentioned above, the Gen4 Ion Air Jet is the most versatile product for “hands-free” operations.  They can be permanently mounted or attached to a Stay Set Hose for flexible adjustments and maneuverability.  EXAIR packages the Gen4 Ion Air Jets with other products to make it easier to set-up, control, and operate.  Here are the packages that EXAIR stocks for quick delivery.

Model: 8194 – The Gen4 Ion Air Jet only.  It comes with a 5 foot (1.5 meter) armored and electromagnetically shielded cable.  They are typically used for permanent mounts with a 1/8” NPT male connection, and are generally purchased with the other packages below.

Model: 8294 – The Gen4 Ion Air Jet with a model 7960 Gen4 Power Supply.  This unit is the basic requirement for a permanent mount application.  The Gen4 Power Supply has two outputs, so it can support another Gen4 Ion Air Jet.

Model: 8494 – Gen4 Ion Air Jet Kit.  This kit includes the Gen4 Ion Air Jet, Gen4 Power Supply, a filter separator and a pressure regulator with coupling kit.  This kit allows for cleaning the compressed air before entering the Gen4 Ion Air Jet as well as controlling the air requirements.  So, you will be able to maximize the efficiency of these units.

Model: 8194-9362 – Gen4 Stay Set Ion Air Jet.  We attach the Ion Air Jet to a 12” Stay Set Hose and a magnetic base with shut-off valve.  The magnetic base will hold the Gen4 Ion Air Jet to a steel surface while the 12” Stay Set Hose gives flexibility to direct the ionized air at a specific point.  This product works great if the Ion Air Jet need to be moved into different locations.  (This does not include the Gen4 Power Supply)

Model: 8294-9362 – This is the Gen4 Stay Set Ion Air Jet (as described in the package above) with a model 7960 Gen4 Power Supply.

Model: 8494-9362 – This is the Gen4 Stay Set Ion Air Jet Kit.  Like with the standard units, this package will add a filter separator and a pressure regulator to the model 8294-9362.

Model: 8495-9362 – Gen4 Deluxe Stay Set Ion Air Jet Kit.  The Deluxe Kit includes additional items to the model 8494-9362 package.  It will include a foot pedal and 10 feet (3 meters) of a compressed air hose.  The foot pedal gives this system that “hands-free” operation to turn on/off the air flow to the Gen4 Ion Air Jet to blow air only when you need it.

Model: 8910 – Gen4 Instant Static Elimination Station.  This has everything you need to connect to your compressed air system to blow ionized air to neutralize and clean your products.  It includes all the items in the Deluxe Kit plus an additional 10 foot (3 meter) compressed air line.  Now you can connect from the compressed air source to the foot pedal to the magnetic base.  Once you attach the Gen4 Ion Air Jet to the supplied Gen4 Power Supply, you are in operation.

Static creates process problems, reduces productivity, and costs you money.  EXAIR manufactures a large line of Static Eliminators that can help you.  If you need a compact, low-cost ionizer to blow off and clean small parts, then the Gen4 Ion Air Jet would be a great option.  You can contact an Application Engineer at EXAIR to see which package would work best for you to remove that static nuisance.

Static Eliminators Essential To Packaging Operations

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:
Gen4 Ion Air Jet ensures bottle caps & necks are static free for application of tamper resistant seals.
  • 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:
Gen4 Ion Air Cannon eliminates static & dust prior to filling bottles.
  • 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:
Initial static charge of almost 17kV (left) is almost completely dissipated by the Ionizing Bar (center) to just 0.04kV (right)

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.

What’s So Great About The Gen4 Ion Air Cannon Static Eliminator?

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.

In my defense, Elle The Cat often looks down on me just like she does on Rocky The Dog. Neither of us care.

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.

Regardless of the nature of the application, if you’ve got a static problem, EXAIR has a solution!

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.
