Gen4 Super Ion Air Knife Cleans Art!

I took a phone call recently from an artist who applies thin colored films to glass sheets. He then uses several panes of that colored glass to build beautiful simplistic art installations! They are so clean and clear every angle you look through you get a different color and view you wouldn’t expect. But he was having a problem, these sheets of glass were building a large static charge and making every bit of dust and dirt stick to the surface. They were spending countless hours painstakingly cleaning every panel of glass because one spec of dirt would ruin the end goal.

Colored Glass Walk Way

Originally they called in to look at the Super Air Knife, which is good to remove dirt, dust and debris – but does not eliminate static if that debris were to be held on to the glass with static. His idea was to poor water on the glass then use the Super Air Knife to blow the water off, messy but they were hoping to kill two birds with one stone. Getting rid of the static and cleaning the glass all at once. He was excited when I told him about out our GEN4 Super ION Air Knife! It would have the ability to neutralize the static charge and blow away any debris clinging to the surface.

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 a web, 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.

Static Solutions for Clean Rooms and Controlled Environments

Clean rooms and controlled environments are a critical spaces for manufacturing, testing or scientific research under conditions which require less contamination from the environment. They have a low or controlled level of pollutants such as dust, other airborne particles, or chemicals. They may also limit specific materials from even entering the room. Many clean rooms work by providing a positive pressure inside the room and filtering the air entering the room. This positive pressure pushes contaminated air out of the room and the filters clean up any air moving into the room. Many controlled environments have specifications on humidity levels, maximum values for static charges, maximum values for the size of particles allowed in the air, temperature, and what materials are prohibited to enter.

With the patented and award winning Intellistat Ion Air Gun and the NEW patented Intellistat Ion Air Nozzle, we have the perfect solution for these scenarios. These are intelligent compressed air® products that create and utilize ionized air to eliminate static and remove troublesome particulates in clean rooms and controlled environments. Using a minimal amount of compressed air, and having a precise blow off pattern, each of these products can reduce static form 5000 volts, to less than 500 in under 1 second. These Intellistat products are balanced to minimize a static charge to +/- 30V, and can be used to eliminate static on some of the most sensitive electronics.

Both of these products are rated Class 5 for Clean Rooms and controlled environments per ISO 14644-1. They are also OSHA compliant for noise and dead end pressure. Other features of both products include a 6mm air connection, and a red and green LED light to signify the ionized air is being produced.

As you can see in the opposing pictures, the differences lay in the delivery system of the Ionized Air. The Intellistat Ion Air Gun offers a short throw, fast acting, and effortless trigger so that the end user can point and shoot the static away. The Intellistat Ion Air Nozzle comes with a compact Stainless Steel adjustable mounting bracket to provide hands free operation. An easy on and off switch on the top is activated and away goes the static.

Please let me know if you have questions, or would like to put these amazing tools to work in your Clean room or other application.

Thank you for stopping by,

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. If you want to discuss the next steps in how static is generated or eliminated we invite you to contact us.
