EXAIR’s Gen4 Ionizing Point: Compact Static Neutralization

Static electricity will be more prevalent under certain environmental conditions like low humidity. It will also appear on applications which have friction, separation, or insulating materials. Luckily, EXAIR has a wide-range of Static Eliminators that are designed specifically to address static issues in a wide variety of industries and conditions. 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.

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.

EXAIR manufactures two products in our Static Eliminator line that do not require any compressed air to operate, the Ionizing Point and the Ionizing Bar. Our Gen4 Ionizing Point is a compact, single point ionizer ideal for a range of winding, rewinding, or slitting operations. It can also be mounted through a duct to neutralize static charges due to moving air or materials.

The shockless Gen4 Ionizing Point delivers a high concentration of positive and negative ions for rapid static decay. It is capable of neutralizing static on the surface of your part or material within 2”. In this image below, a series of Gen4 Ionizing Points are being used to neutralize static from a playing card slitting operation.

The Ionizing Point is just one of our many Static Eliminators available from stock. If you’re experiencing static in any of your applications or processes, EXAIR has a solution available ready to ship. Give us a call and we’ll be happy to help point you in the right direction.

Eliminate Static on Hose, Tube, and Extruded Shapes w/ EXAIR’s Gen4 Super Ion Air Wipe!

Gen4 Super Ion Air Wipe

This time of the year it is not uncommon to feel a slight shock after walking across a carpeted surface and touching a door knob. This little “jolt” is a result of fast-moving electrons leaping from your body to the door knob, or vice versa. As your feet shuffle across the surface of a rug or carpet, your body will either gain or lose electrons. Touching a conductive surface then causes these electrons to leap from one place to another.

When an atom gains or loses an electron, it affects the balance that occurs within an atom. If an atom gains an electron, it now has more electrons than protons. This results in a negatively charged atom. The opposite can be said if an atom loses an electron, it now carries a positive charge. This charge imbalance is where static electricity comes from. Both positive and negative charges will remain static until contacted by or in close proximity to a conductive or grounded surface.

Static can be a problem in many industries contributing to a range of different process problems. Common problems include: dust clinging to product, product clinging to itself, rollers, machine beds or frames, materials jamming or curling, sheet feeding problems, and hazardous sparks or shocks to operators.

For eliminating static on the surface of pipe, cable, extruded shapes, hose, or wire, look no further than EXAIR’s Gen4 Super Ion Air Wipe. The Gen4 Super Ion Air Wipe provides a uniform 360° ionized airstream and is available in both 2” and 4” ID sizes. Its clam-shell design makes it easy to clamp around a part for neutralizing static electricity and contaminants.

The high volume, high velocity airflow attaches itself to the surface and wipes it down with static eliminating ions. The airflow stays attached to the surface and is effective up to 15’ away from where it’s mounted. It’s lightweight and easy to mount using the ¼-20 tapped holes on the back or can also be held into place with just rigid pipe.

If you’d like to talk about how EXAIR can help solve the static problems in your facility, give us a call. With a wide range of Static Eliminators available to ship same day from stock you can consider these problems a thing of the past!

Ion Air Cannon Keeps Paper Recycling Baler Working

One of the cruelest pranks I’ve ever been party to happened during my time in the United States Navy. All it took was:

  • A cigar box
  • A rubber band
  • The scrap “dots” from every 3-hole punch we could find

We cut the lid off the cigar box, filled it with the “dots,” used the lid and the rubber band to make a wind-up flapper that we stretched across the open top of the box, and carefully placed it in our Leading Petty Officer’s (LPO’s) desk drawer.  Then we waited for hilarity to ensue the next time he opened that drawer.

Unbeknownst to us, he was going to a pretty important meeting that morning, so he was wearing his Service Dress Blues (also known as “crackerjacks” – the dark wool one; not the white one on the popular snack mix box).  When he opened his desk drawer, the rubber band-powered flapper flung those little white paper dots all over him.  It was wintertime, in an office space with electric baseboard heat, so the static cling was heinous.  It took several of us with makeshift lint brushes fashioned from duct tape to get his uniform “shipshape” and presentable for the meeting.

I was reminded of this incident recently when I had the pleasure of helping a caller from a paper recycling plant, who was having a static problem in a baler, with, basically, large confetti-like pieces of shredded paper.  These shreds are pneumatically conveyed through a long 8-inch duct, where they picked up enough static to cling to the inside of the baler chute, and built up to a point where they covered the sensors that opened the chute.  This caused the chute doors to cycle without the chute being full, which triggered the baler to activate with nothing there.  The result from the operators was a lot of slamming, frustration, and cursing…which further reminded me of my LPO’s reaction to getting covered in paper dots.

While lint brushes (and duct tape, in a pinch) work just fine for removing statically charged debris from one’s clothing, the baler required a different solution…in the form of a pair of EXAIR Gen4 Ion Air Cannons.  These were installed to blow into the baler, from opposite walls just above the chute, and aimed slightly down towards the sensors.  This keeps the sensors clear until paper shred actually DOES fill the chute, allowing it to dump a whole bale’s worth of scrap, keeping the baler (and the operators) happy.

Whatever you needs, EXAIR has a Gen4 Static Eliminator product to solve your static problem.

Many industrial static charge problems have similarities to “real world” experiences that most of us are familiar with.  If you want to talk about static control, give me a call.

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.
