Static Season is in Full Swing, Super Ion Air Knives can Remove the Shock!

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.

They combine 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. Some of the issues static causes include, dirt and dust buildup on surfaces, misreads for sensors, poor quality from ink jets, poor print quality on printed surfaces, and personnel getting shocked.

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.

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.

Eliminate Static from Many Applications Using Super Ion Air Knives

By combining an Ionizing Bar with a Super Air Knife, the Super Ion Air Knife provides rapid static elimination AND blow off of any dust, chips, or debris that was being held to a surface by static electricity.  The laminar curtain of ionized air not only maximizes the rate of static removal, but is also ideal for stripping/sweeping away any debris which leaves a clean, static-free surface.  No more jamming, tearing, nuisance shocks to operators, dust attraction, or any of the many problems associated with static electricity.

The ionized air flow can be precisely regulated to whatever level it takes to get the job done.  At 100psig, the powerful, high velocity blast will dissipate 5,000 volts of static charge in 0.18 seconds!  If the material is fragile, or if that kind of air flow might disrupt the process, it’s not a big deal…even at 5psig supply pressure, that same 5,000 volts is dissipated in 0.40 seconds.  That’s how it works on the plastic roll above – with just a whisper of ionized air flow from a Super Ion Air Knife, they consistently reduce the resultant static charge to less than 400 volts…far below the threshold for the nuisance shocks they wanted to avoid.

Gen4 Super Ion Air Knife Performance

They’re on the shelf in lengths from 3 inches to 9 feet long, and we can make custom lengths in three days after receipt of an order.  The 115/230VAC Power Supplies are available with 2 or 4 outlets, to energize from 1 to 4 EXAIR GEN4 Static Eliminators.

Versatile. Efficient. Effective. Quiet. Safe.  And, readily available.  If you’d like to discuss a static problem, give us a call.

Static Eliminators: Ion Air Jet

Static charge causes a variety of problems & challenges in industrial applications:

  • It “zaps” operators who have to handle statically charged materials.
  • It makes sheets and films cling to each other.
  • It can cause tearing or jamming of those sheets and films as well.
  • Objects with high static charges can cause sensors or sensitive electronics to malfunction, and it the charge is high enough, even damage them.
  • It makes dust cling to parts and material that you want to keep clean.
  • It can lead to uneven or spotty coverage if the statically charged piece is to be painted, coated, printed on, etc.

Good news is, static charge is pretty easy to dissipate, and EXAIR Corporation offers a number of solutions that are simple to install and easy to operate.  Among them is the Gen4 Ion Air Jet.

The Gen4 Ion Air Jet generates a concentrated flow of ionized air, which is ideal when you need to focus on a specific spot without disturbing anything in the surrounding area.  They’re quiet, efficient, and OSHA compliant.  They are also available with a number of options to further simply installation & operation:

If you can hard plumb an air pipe directly, the Gen4 Ion Air Jet is ready to go, right out of the box.
