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 Gen4 Stay Set Ion Air Jet includes a Magnetic Base and 12″ Stay Set Hose, for quick setup and easy aiming of the ionized air flow, exactly where you want it.

The Magnetic Base and Stay Set Hose make it a breeze to mount & aim your Ion Air Jet.

The Gen4 Instant Static Elimination Station adds a foot pedal and two 10ft compressed air hoses, perfect for hands-free on/off operation.

For a total hands-free solution, look no further than the Model 8910 Instant Static Elimination Station.

The Gen4 Deluxe Stay Set Ion Air Jet Kit adds an Automatic Drain Filter Separator and Pressure Regulator so you can keep your air supply clean & moisture free, and dial in the flow & force of the ionized air stream, from a breeze to a blast, or anywhere in between, depending on the needs of your application.

The Model 8495-9362 Deluxe Stay Set Ion Air Jet Kit has everything you need, right out of the box.

We offer two Power Supply options: the Model 7960 has two ports, which will operate any two EXAIR Static Eliminator Products, and the Model 7961 has four ports, to operate up to four Static Eliminators.  They’re switchable for operation with either 115VAC or 230VAC, and come with both cables for your convenience.

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

The Gen4 Ion Air Jet is just one of EXAIR Corporation’s eight distinct lines of Static Eliminator Products.  If you’ve got a problem with static charge, we can help.  Give me a call.

EXAIR Eliminates Static – Public Enemy Number one in the Printing Industry

Static electricity is the enemy of the printing industry. Downtime and inefficiency caused by static means longer lead times and angry customers! EXAIR can remove static electricity in the many printing applications across wide and narrow webs.  With our rugged line of EXAIR Super Ion Air Knives and Ionizing Bars, EXAIR can improve your efficiency and printing quality.

Digital printing dries out the printed substrate, creating high static charge that can cause printing defects, ink overspray, and even print head clogging and print head shorting issues. If a press is printing on non-porous substrates like plastic, metallics and highly coated glossy papers, a device called a corona treater is used to increase the surface energy of the substrate to ensure the ink droplets adhere and do not spread too much on the substrate. A byproduct of the corona treatment is static charge, which must be removed. This can be achieved by installing an EXAIR Ion Bar after the corona treatment device across the web.

Static is also created anywhere in the printing or finishing operations where sheets are moved over each  other.   Sheet-fed presses, for example, create friction in the stacking of individual sheets on top of each other.  This friction induced static creates misfeeds, print registration issues, multiple sheet pickups and equipment jams.

Folding operations cause static issues too. Like a sheet-fed press, static is created by folded pieces being dragged across each other.

In both cases, installing an EXAIR Super Ion  Air Knife or Ion Air Cannon that can direct a stream of ions between the stack and the top sheet can eliminate the static that causes misfeeds and jams.

The typical easy fix printers employ is what’s called a tinsel bar. Also called garland, it looks just like what you drape on a Christmas tree, except that it’s made of highly conductive copper that needs to be grounded to the printing press.The problem with tinsel bars is that although they are cheap initially, they don’t last long. They’re not a set-it-and-forget-it solution. The sharp strands work on induction and interact with the static field on the substrate creating a neutralizing cloud that surrounds the area, reducing both positive and negative ions. Printing operations are usually dusty environments and when the tinsel becomes dusty, oxidized, or matted and crumpled, they don’t work as effectively.

Static is also created in unwinding and rewinding operations, when rolls are slit to needed widths of various presses. The removal of the web from the roll creates static charge that attracts dust to the substrate surface and can cause major problems in downstream printing operations. Installing an EXAIR Ion Bar on top of the web can eliminate this static.

EXAIR Super Ion Air Knives don’t need to be placed close to the surface like a tinsel bar. Static dissipation of 5 KV can occur in less than a half second up to 20 feet away and can be adjusted from a blast to a breeze, depending on static level.

If you are a printer, finisher or labeler, EXAIR has a static elimination product that can improve your operations. For more help you can contact one of our EXAIR application engineers to talk you through a solution.

Static Elimination Improves Credit Card Printing and Production

PVC Base Sheet for Credit Cards

A company that made credit cards was having issues in their print quality, and static was the culprit.  They used PVC sheets as a base material to print on, and like with any non-conductive materials, static can be generated easily and create problems.  For this company, static was attracting dirt to the surface of the material, causing blemishes in the print.  They contacted EXAIR to find a solution.

When non-conductive materials slide, hit, peel, and rub; electrons from the surface can move from one atom to another; thus, creating static.  The type of material and the amount of movement governs the amount of static forces.  These strong static forces can attack debris and fibers, as well as generate shocks, misalignment, and machine jamming.  Another feature of static is that it can regenerate if the materials continue to slide, hit, peel, and rub.

For the company above, they were printing on 30 cm by 48 cm (12” X 19”) PVC sheets.  They used three different processes to print a complete credit card; silkscreen, digital, and offset.  After each printing process, they would lose sections of the sheet due to poor image quality.  At the end, they were losing between 20 to 30% in visual rejections.

For this application, we had to do two operations; remove the static and clean the surface from debris.  The Gen4 Super Ion Air Knife can do both of these operations at the same time.  With the laminar air stream that comes from the Super Air Knife, it can carry both positive and negative ions from the attached Gen4 Ionizing Bar.  Together, they can remove any type of static charge as well as becoming a very effective tool as a non-contact wiper to remove debris.  With this ability, the print quality would not be affected during cleaning.  Since static is a surface phenomenon, I recommended to also remove the static from the other side of the sheets.  We did not want to have any dirt or debris that could be remaining on the bottom surface to transfer from one surface to the next during stacking.  This could scrape the finish during loading and unloading of the sheets.

I recommended two pieces of a model 112012 Gen4 Super Ion Air Knives that are manufactured to 12” (30 cm) in length.  This customer can easily mount one above the sheet and one below the sheet prior to printing.  To operate the attached Gen4 Ionizing Bar, EXAIR offers two types of power supplies, a two-output unit, model 7960, and a four-output unit, model 7961.  They can save you money when needing multiple Static Eliminators to operate in your system.  With a model 7960 Gen4 Power Supply, they now had a system to remove static and clean the sheets.  Once they installed the Gen4 Super Ion Air Knives onto their system, the rejection rate dropped to near zero.

All EXAIR Gen4 Static Eliminators use one of two Power Supplies – your choice of the 2-port Model 7960, or the 4-port Model 7961.

Rejected parts are costly, wasteful, and reduce production rates.  If you have rejection from static problems in your system, EXAIR has a large line of Static Eliminators to help you.  You can contact an Application Engineer to review your application.  For the customer above, the Gen4 Super Ion Air Knives made it possible to generate more credit cards per sheet.
