Ion Air Jet Applications

While writing my blog last week on all of the features & benefits of the Gen4 Ion Air Jet, I couldn’t help but think of some of the very interesting and successful uses I’ve seen in my nine years (as of this past Monday) as an Application Engineer at EXAIR Corporation.  In honor of my workaversary, this week’s edition is Russ’ Top 9 Ion Air Jet applications:

  1. A medical device manufacturer uses Ion Air Jets to remove dust from plastic extrusion as it goes through a puller belt.  The small diameter (0.05″ to 0.10″) made the Ion Air Jet a more efficient fit than the Super Ion Air Wipe, which is commonly used for extrusions like this, but is most effective for larger diameters.
  2. A maker of large scale automated machinery has provided Ion Air Jets (as well as other EXAIR quiet, efficient, and safe compressed air products) on machines they’ve been selling their customers for years.  When they started machining their own plastic parts, the Ion Air Jet was their first thought for a solution when plastic chips started sticking to their drill bits.
  3. A commercial printer makes displays, signs, etc. from a variety of static-prone materials such as acrylic, polycarbonate, and styrene.  They use CNC routers to cut them to size & shape, form the edges, and add dimensional detail.  Ion Air Jets blow the dust & shavings away, and keep them away, greatly reducing the prep time between routing and assembly.
  4. A weather sealing/stripping manufacturer uses Ion Air Jets to remove statically charged dust from their rubber & foam product extrusions, allowing for increased line speeds and better cuts for the products they cut for specific seal packages for the residential & commercial door and automotive industries, among others.
  5. A major provider of electrical and electronic contactors uses Ion Air Jets to blow off contact strip as it rolls off large reels to remove protective film and static.
  6. A manufacturer of wire marking machinery installs Ion Air Jets on their machines that are used to print on products with especially static-prone jackets, to ensure clean and crisp markings
  7. A cable manufacturer that caters to the computer & electronic industries uses Ion Air Jets to remove static & dust as foil is applied to PVC coated wire.  This eliminates the static charge that was causing inconsistencies when the adhesive was heated to activate.
  8. A wholesale food equipment distributor uses Ion Air Jets to blow out bottles during the sterilization process, prior to filling.
  9. A maker of specialty polymers uses Ion Air Jets to keep fine powders from accumulating in the entries into their hoppers.
Some applications call for a fixed-in-place solution, like the (above, from left) Super Ion Air Knife, Super Ion Air Wipe, Ion Air Jet, and Ion Air Cannon.) Others are best suited to the hand-held convenience of the Ion Air Gun.  Whatever your static problem is, though, EXAIR has a solution for you!

If you have a problem with static, the Ion Air Jet is just one of the solutions EXAIR Corporation can provide.  If you’d like to find out more about how we can help, give me 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.

The Gen4 Stay Set Ion Air Jet includes a Magnetic Base and 12″ Stay Set Hose, for quick setup and easy aiming of the ionized air flow, exactly where you want it.

The Magnetic Base and Stay Set Hose make it a breeze to mount & aim your Ion Air Jet.

The Gen4 Instant Static Elimination Station adds a foot pedal and two 10ft compressed air hoses, perfect for hands-free on/off operation.

For a total hands-free solution, look no further than the Model 8910 Instant Static Elimination Station.

The Gen4 Deluxe Stay Set Ion Air Jet Kit adds an Automatic Drain Filter Separator and Pressure Regulator so you can keep your air supply clean & moisture free, and dial in the flow & force of the ionized air stream, from a breeze to a blast, or anywhere in between, depending on the needs of your application.

The Model 8495-9362 Deluxe Stay Set Ion Air Jet Kit has everything you need, right out of the box.

We offer two Power Supply options: the Model 7960 has two ports, which will operate any two EXAIR Static Eliminator Products, and the Model 7961 has four ports, to operate up to four Static Eliminators.  They’re switchable for operation with either 115VAC or 230VAC, and come with both cables for your convenience.

Model 7960 Gen4 Power Supply (top) has two ports; Model 7961 (bottom) has four, depending on how many Static Eliminators you wish to operate from the same Power Supply

The Gen4 Ion Air Jet is just one of EXAIR Corporation’s eight distinct lines of Static Eliminator Products.  If you’ve got a problem with static charge, we can help.  Give me a call.

EXAIR Gen4 Ionizing Bar Removes Static From Corona Treated Plastic

If you want to print on plastic, it’s challenging – most plastics are chemically inert and non-porous.  That means you can apply all the ink you want; it’s not going to stick.  In the 1950’s, a Danish engineer named Verner Eisby experimented with various techniques to overcome these challenges.  He found that exposing the surface to be printed on to gas flame or sparks modified the surface to improve adhesion with the ink.  It did so, though, in a crude & uneven manner, leaving imperfections & inconsistencies in the printed product.  He then tried applying a high frequency corona discharge in a linear array.  The plasma (gas in an ionized state) generated left a homogeneously treated surface on which to print, smoothly & evenly.

This has become the “industry standard” for many of the labels we see on commercial products, from shampoo & wine bottles on the grocery store shelf, to pennants & banners at public events.  It also leaves the surface even more prone to picking up a static charge from rolling or unrolling, stacking, sliding, etc.

One of our customers makes a great many labels for all kinds of these commercial products, and uses an EXAIR Gen4 Ionizing Bar immediately prior to the printing operation:

Model 8024 24″ Gen4 Ionizing Bar removes static from Corona treated plastic label film.

EXAIR Corporation has a variety of Static Eliminator Products to fit most any industrial or commercial application.  If you’d like to find out more, give me a call.

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.
