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 3 Types of Static Generation

Static electricity is something that we talk about often here at EXAIR, particularly during the colder winter months. When an atom gains or loses an electron from its outer shell, it becomes electrically imbalanced. A material’s propensity to either gain or lose an electron is “ranked” on a list known as the Triboelectric Series. So how does static actually generate, or what causes these atoms to either gain or lose an electron? There are three types of static generation: contact, detachment, and frictional static build up.

Contact static build up is one of the simplest methods of static generation. In this type of static generation, a charge is generated simply from two objects contacting one another and separating. This often results in an instantaneous static charge as the electrons are transferred from one object to another in accordance with the Triboelectric Series.

As a layer of material is peeled off, electrons are transferred from one sheet to another.

The second type of static generation is known as detachment static buildup. The principle behind the type of static electricity is the same as contact static buildup, but the materials are already in contact with one another and the charge is generated as the surfaces are separated. During the separation, not all of the electrons are able to get back to their original molecule. The amount of static generated in detachment static buildup is generally far greater than contact static buildup due to the large surface area.

The last type of static generation is frictional static buildup. When two objects have friction between one another, electrons in the outer valences of the molecules can easily pass from one atom to another. If the force pressing the objects together increases, even more molecules come into contact with each other and increase the charge that is generated. Just as detachment static buildup, frictional static buildup generally produces higher charges than contact static buildup.

Static Electricity: What Is It And The Products To Solve Industrial Process Problems

The lower relative humidity associated with the cold, dry air of winter results in a significant increase in customers  with problems related to static. Luckily, EXAIR has a wide-range of Static Eliminators that are designed specifically to address static issues in a wide variety of industries. So, what exactly is static and how is it generated? Let’s take a quick trip down memory lane to elementary school science class….

An atom consists of three basic particles: protons, neutrons, and electrons. The protons (positively charged) and neutrons (neutral charge) form the nucleus. Outside of the nucleus, electrons (negatively charged) are quickly zipping around in orbits at specific distances from the nucleus. These electrons are bound to the nucleus due to electromagnetic force. Opposite charges attract. Since the protons in the nucleus carry a positive charge this acts on the negative charge of the electrons and keeps them in orbit. The closer the electron to the nucleus, the stronger the bond and the more energy required to break that electron from its original orbit.

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. 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.

To eliminate these charges, EXAIR’s Static Eliminators produce an equal amount of both positive and negatively charged ions. This allows us to neutralize either charge quickly and effectively.

For applications that allow you to install close (generally within 2”) to the surface of the material, we offer our Ionizing Bar in lengths ranging from 3”-108”. If a wide area of coverage is necessary, but you can’t get close to it, the same Ionizing Bar is installed on the Super Ion Air Knife to help deliver those ions over a greater distance.

The Ionizing Point is another product that can be used without the need for compressed air. A compact, single point ionizer, this product is ideal for winding, rewinding or slitting operations. It can also be mounted through a duct to neutralize static charges due to moving air or materials.

The Ion Air Gun combines incredibly fast static decay rates with low compressed air consumption. With a 10’ flexible armored cable and ergonomic handle, the Ion Air Gun is best for applications where an operator will perform the blowoff process.

If the airflow pattern from the Ion Air Gun is conducive to your application, but you’d prefer to automate the blowoff or maintain a continuous usage, both the Ion Air Jet and the Stay Set Ion Air Jet provide an identical airflow pattern. The Stay Set Ion Air Jet comes with a magnetic base and Stay Set Hose, allowing you to precisely position the static eliminating ions in your process.

The Ion Air Cannon delivers a quit, efficient, and concentrated flow of ionized air. It is ideal for hard to reach spaces or confined areas that necessitate a solution to static problems. Designed with a sturdy stand, the pre-drilled holes can be wall, bench, or machine mounted. It incorporates a swivel adjustment for directing the airflow.

Our Gen4 Static Eliminators have all 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. If there’s a process in your facility that could benefit from a solution to static problems, please give us a call. Any of our Application Engineers will be happy to help select the best option for your process.

The Impact of Cold Temperatures and Lower Humidity on Static Electricity

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. This is known as static electricity.

2843109634_8982d7710c_o

If you notice, this happens to occur much more often during colder winter months (if you’re one of those fortunate people to live outside of this sensation we call “cold” please don’t rub it in!). The reason that you experience static shocks more frequently during winter is due to the relative humidity. At colder temperatures, air does not hold as much moisture as it does when it’s warm and moisture helps to conduct electrical charges. Even though you’re heating your house to a similar temperature, the air that is being drawn into your home and heated is still the dry cold air containing less moisture.

The amount of moisture in the air is expressed as relative humidity. This value is given as a percentage of water vapor in the air, compared to how much it could hold at that temperature. In conditions of lower relative humidity, static charges build up much easier. When the relative humidity is high, there’s a higher concentration of water molecules present in the air. These water molecules “coat” the surface of the material, allowing electrons to move more freely and form a layer over the material. This layer of water molecules acts like a lubricant, reducing the forces that cause static to generate. This is why static is much more noticeable during the winter months.

There are many applications that static only appears when the seasonal climate changes. Issues can manifest in the form of nuisance shocks to operators, materials jamming, tearing or curling, product sticking to itself and to rollers, dust clinging to product, and many more. If static is causing problems in your processes, we have a wide variety of Static Eliminators available from stock. Don’t just deal with the problems until humid conditions return, get a permanent solution in place that’ll neutralize the static and eliminate a troublesome application. Contact an EXAIR Application Engineer today and we’ll help to diagnose the root cause of the problem and recommend the best solution.
