Here on the EXAIR Blog you’ll often find a host of applications and discussion centered around static electricity during the fall and winter months. The reason for this is that during periods of lower humidity, it’s much easier for static to build up and pose problems for a variety of industrial processes. During the summer, higher levels of humidity “coat” the atoms of a molecule and reduce the amount of static buildup.
With that being said, just because it’s right in the middle of summer where humidity levels are rather high doesn’t mean all static problems go away. Some applications generate such a high level of static that they require a solution year-round. Such was the case for a recent customer that manufactures a wide variety of various styles of cans and cups used by the food industry.
For a new process for one of their customers, they apply a wax to the coil stock using an electrostatic waxer in front of their cupper lines. The waxers run at -20Kv to charge the atomized wax particles to attract to the positive charge on the coil stock. The coil stock then carries a residual charge as high as 18Kv and in less than a minute would immediately cling to their cupper die press. Without a solution for removing the static, they were unable to run this machine.
The coil stock width ranges from about 33-34” and carried a charge on either side of the material. The recommended solution was to install (2) of our Model 112036” Super Ion Air Knives just in front of the material’s entry into the cupper die on top and bottom of the coil stock. They were up against a firm deadline to get material completed and to their customer. A delay in other components had pushed them right up against their commitment to deliver finished cans to their customer, something we’re all becoming all to common with nowadays.
Fortunately for them, EXAIR had the parts available and in stock. We shipped them out the very same day for next day early AM delivery. They had them up and installed before lunch and production was resumed. At a time where it seems everything is out of stock for a number of reasons, EXAIR is still shipping orders out same day. If you need a solution, and you need it fast, give us a call.
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.
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 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.
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.
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.
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.
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.
