Two Specialized Air Guns for Static Removal

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.)
  • This is our rugged, industrial use model which can be seen in assembly, packaging, painting/coating and plastics processes.
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.  Another handheld Static eliminator is our Intellistat Ion Air Gun, this product is more geared towards clean room type applications.

EXAIRs’ Intellistat Ion Air Gun has earned a Class 5 Cleanroom Rating making it ideal for static elimination in cleanrooms for sensitive processes. There are manufacturing processes that require certain cleanliness standards for operation in such as scientific research, solar panel manufacturing or biotechnology industries. This means that any tool or material you use in this process has to meet a certain standard. EXAIR’s Intellistat was engineered to do just that.

EXAIR Intellistat Ion Air Gun

The Intellistat Ion Air Gun is a patented handheld air gun for static elimination in sterile environments and clean rooms. This lightweight tool provides rapid static decay with a simple squeeze of a short-throw trigger reducing 5,000 volts to 500 in under second. Furthering the Intellistat’s utility, it has now been awarded the ISO 14644-1 Class 5 rating for clean rooms and controlled environments making it the perfect tool for electronics manufacturing, testing facilities and laboratories.

The Intellistat is the ideal solution for static elimination in your sensitive processes. Learn more about the Intellistat as well as the rest of EXAIR’s large line of static elimination products at www.EXAIR.com or by contacting any of our Application Engineers.

EXAIR Gen 4 Power Supplies

EXAIR offers systems for total static control. When static is a problem on moving webs, sheet rock, three dimensional parts, extrusions or packaging, EXAIR has a solution. The Gen4 static eliminators (also called ionizers) will eliminate the static charge. The shockless ionizers are use a power supply and produce a bulk of positive and negative ions. The charged surface attracts the appropriate number of positive or negative ions from the ionizer to become neutral (discharged).

Gen 4 Power Supplies

The two and four outlet Gen 4 power supplies have selectable voltage which allows you to choose input voltages of 115 VAC or 230 VAC. The modular power cable with electromagnetic shielding protects sensitive electronics against electromagnetic interference while easing connections and routing. One cable is for domestic USA power outlets and another is included to facilitate international outlet plugs. An integrated fuse on the primary protects against voltage spikes.

The two and four outlet selectable voltage Gen 4 power supplies require an input of 115VAC, 50/60 Hz or 230VAC, 50/60 Hz. A 6′ (1.83m) modular power cord and lighted power switch are included. Power supplies are UL Component Recognized to U.S. and Canadian safety standards, and are CE and RoHS compliant.

One power supply is able to power up two or four Gen4 static eliminators, which minimizes the space required for installation. EXAIR will build custom length cables to minimize the number of power supplies needed when products are spaced out. Each power supply can power up to 100′ of total cable length from any Gen4 static eliminators which are connected. For example, a two outlet power supply can have two Gen4 static eliminators with 50′ cables installed. The integrated high voltage connections to accept any Gen4 static eliminator are made from stainless steel to provide durability.

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

Combining our engineered airflow products with ionizers gives the ability to eliminate a static charge quickly from from great distances. Laminar flow airstreams make it possible to blow away contaminants and eliminate the charge that attracts them. If you have questions or want additional information please contact any of our Application Engineers for additional details and data.

Structure of an Atom

The structure of an atom plays a role in the development of static electricity. Static, as you may know, causes disruption within many industrial and manufacturing processes and environments. It can shock personnel, create poor results on printing processes and product finishes, and cause process lines to jam or sensors to malfunction – just to name a few.

Before stepping into the Basics of Static Electricity, we may want to have a solid foundation on the makeup of matter. The foundation of all matter is the atom. All objects are comprised of matter. Matter is made of molecules, which are made up of atoms. All the atoms are built out of electrons, neutrons and protons. The molecule is the smallest measurement of matter that can exist by itself and still contain one or more atoms.

Atom Diagram – 1

The structure and how these individual atoms and their components react is the groundwork for electron theory. Each component of the atom – the proton, neutron, and electron, are thought to carry with them a charge which also has a polarity to it. Neutrons have a neutral charge and contribute to the mass of an atom. The negative charged electrons, are lightest weight and will repel other electrons since they are the same polarity, they repel each other. Protons, being the positively charged carry a heavier mass and generally become attracted to the Electrons due to their polarities being opposing – opposite polarities attract each other.

Static

Said again, opposite polarities attract and like polarities repel. This movement is what begins the actions and reactions which are described throughout the Basics of Static Electricity Interactive White Paper that is available through our site.

Playing Card Manufacturer Gets Dealt a Bad Hand from Static Electricity

Okay, so I’m not talking about counting cards in Las Vegas, like was shown in the movies Rain Man or 21. I’m talking about how a manufacturer of playing cards may count them. I visited a manufacturer of playing cards. It was fascinating learning that they only use specific relative humidity cardstock for certain geographic locations. It totally makes sense once I thought about it, send a “wet” card to a dry geographic location and it will warp or shrink, send a “dry” stock to Atlanta and you’ll get wrinkled swollen cards once they hit the humid air. This manufacturer handled every aspect of the cards. They always ran into issues when it came to a single production line.

This production line would take the printed sheets of cards, which would get placed in a large stack then fed through a cutter that would result in columns of cards, then stack and cut the columns into single cards. They would then get stacked again and the machine would then fan them out. The machine used two friction band conveyors to move the cards at a high rate of speed. They moved so fast it looked as though they overlapped. It was only when you fixated on a single card and followed it you would see it was separated by a few inches from the next.

This machine would stack all the cards up then separate them to each number and suit by dropping them into a chute. Next, it would drop the cards out of those chutes and recombine them into a stack of eight complete decks of cards. It would box them, label it and spit it out. They then went to casinos. This machine was a static nightmare when running dry card stocks during the winter months in the dry air.

Model 7905 Digital Static Meter

The cards would stick together, double feed, and really just leave the company with a bad hand. When I visited though, I had an Ace up my sleeve. I had a Static Meter and a Gen4 Ionizing Point in my possession. The static meter was used to identify the highest static levels in their process, and the Ionizing Point, which we were able to easily hold within 2″ of the cards where they were first jamming. Which was the very first fanning operation. Once the Ionizing Point was installed at this location, rather than seeing any misfeeds or jams within the first 3 stations, the problem moved to “drop station number five”. We then added another to just before the fifth station and saw improvements down to station nine.

Friction / Attachment / Detachment Static

The key observation here was that it was not possible to eliminate the static throughout the entire process. This is because there is a constant generation of static due to friction of the belts sliding under the cards and the cards being stacked then slid out from one another. As soon as the cards would leave the ionized 2″ radius around the Gen4 Ionizing Point the static would begin to regenerate on the surfaces. While it wouldn’t immediately reach a problematic point for this process, it would build up over the course of a few stages. This is why it is critical to place a static eliminator at the point it is causing the problem, rather than just at the beginning of a process, and then assuming static will not come back.

Gen4 Ionizing Points

In order to reach the solution, we implemented an Ionizing Point at each location that was experiencing an issue. The number of finished decks the company was able to produce, increased. They moved on to the packaging station and made their way into the casinos.

If you would like to discuss a Gen4 Ionizing Point or any point of use compressed air process / manufacturing process, please let us know.
