EXAIR has decided to open up our product line for areas that do not have or wish not to use compressed air.  This award-winning EXAIR Varistat® Benchtop Ionizer is a powerful fan-driven static eliminator engineered to neutralize static charges on surfaces in demanding industrial environments. This Ionizer delivers a consistent stream of ionized airflow, effectively eliminating static and particulate without the need for compressed air. The Varistat is now available in 230 volts to meet the needs of industrial locations. Easily mounted on bench tops or machines, this static eliminator is manually adjustable and perfect for processes needing comprehensive coverage.

            The new 230-volt Varistat sets itself apart from other fan-driven static eliminators by offering highly adjustable features and allowing for versatility. Features like selectable voltage 115VAC/230VAC, variable fan speed, and adjustable polarity make the Varistat a complete solution for eliminating static in a variety of processes and facilities. Once plugged in, the Varistat provides rapid static decay capable of reducing 1000V to 100V in 0.8 seconds. This product features two replaceable ion emitter points and two 30 PPI foam filters to ensure optimal performance over extended periods, as well as LED lights to signify proper function.

            The Varistat is part of an extensive line of static eliminating products from EXAIR that are UL listed and CE compliant. Products like the Intellistat Ion Air Gun, the Gen4 Super Ion Air Knife, and the Gen4 Ionizing Bar, exhibit the wide range of static solutions offered and the ability to combat static in a variety of manufacturing processes.

For U.S. and Canadian customers, EXAIR offers a 30-day unconditional guarantee on our cataloged items to try.  You can see how effective the Varistat Benchtop Ionizer or any of our Static Eliminators can be.  If you need help in selecting the best product for your application, an Application Engineer will be happy to help you.  And for qualified orders until March 31st, 2025, you will receive a complimentary AC Sensor, a $76.00 value, for free.

Eliminate Static from Many Applications Using Super Ion Air Knives

By combining an Ionizing Bar with a Super Air Knife, the Super Ion Air Knife provides rapid static elimination AND blow off of any dust, chips, or debris that was being held to a surface by static electricity.  The laminar curtain of ionized air not only maximizes the rate of static removal, but is also ideal for stripping/sweeping away any debris which leaves a clean, static-free surface.  No more jamming, tearing, nuisance shocks to operators, dust attraction, or any of the many problems associated with static electricity.

The ionized air flow can be precisely regulated to whatever level it takes to get the job done.  At 100psig, the powerful, high velocity blast will dissipate 5,000 volts of static charge in 0.18 seconds!  If the material is fragile, or if that kind of air flow might disrupt the process, it’s not a big deal…even at 5psig supply pressure, that same 5,000 volts is dissipated in 0.40 seconds.  That’s how it works on the plastic roll above – with just a whisper of ionized air flow from a Super Ion Air Knife, they consistently reduce the resultant static charge to less than 400 volts…far below the threshold for the nuisance shocks they wanted to avoid.

Gen4 Super Ion Air Knife Performance

They’re on the shelf in lengths from 3 inches to 9 feet long, and we can make custom lengths in three days after receipt of an order.  The 115/230VAC Power Supplies are available with 2 or 4 outlets, to energize from 1 to 4 EXAIR GEN4 Static Eliminators.

Versatile. Efficient. Effective. Quiet. Safe.  And, readily available.  If you’d like to discuss a static problem, give us a call.

A Tale of Two Super Ion Air Knives

A manufacturer of plastic bottles had a problem with static charge. Right after the bottles are extruded and cooled, they have an apparatus that “unscrambles” them and places them, single file, onto a conveyor. It does so with some fabric belts and plastic rollers. If you know anything of static electricity, dear reader, you probably recognize that there aren’t too many better ways to generate a static charge than to rub plastic against plastic, or (even worse) plastic & fabric together.  Here’s a prime example of the kind of static charge you can get, just from unrolling plastic film.

The separation of the non-conductive surfaces (like when this plastic film is unrolled) is capable of generating an incredible amount of static charge.

Now, the bottle makers didn’t have a static meter, but they didn’t need one to know they had issues:  the bottles that the “unscrambler” was putting on the belt were still very much “scrambled.”  They installed a Model 112209 9″ GEN4 Super Ion Air Knife Kit, to blow ionized air up from under the bottles as they entered the belt conveyor, and they did see what they’d call an improvement, but not quite what they’d call a solution.

Unfortunately, dissipating the static from just about half of the surface area of the bottle was still leaving them with half a problem.  However, by adding a Model 112009 9″ GEN4 Super Ion Air Knife (the 112209 Kit’s Power Supply has two outlets, and its Filter Separator & Pressure Regulator are capable of handling the flow to two 9″ Air Knives,) they were able to blow ionized air down from the other side, and up from where the first one was installed.  A soft “breeze” was all it took…a stronger air flow would have worked against the “unscrambler” anyway…because even at very low supply pressures, the Super Ion Air Knives produce an extremely fast static dissipation rate.

Even with a 5psig supply…which makes for just a “whisper” of air flow, the EXAIR GEN4 Super Ion Air Knife eliminates a 5kV charge in under half a second.

If you’ve got problems with static charge, we’ve not only got improvements; we’ve got solutions. Give me a call to find out how we can help.

EXAIR’s Super Ion Air Knife Eliminates Static

One of the best ways, in industry, to generate a static charge is to roll or unroll non-conductive materials such as polymer films, plastic sheet, etc. It’s common to see static charges well in excess of 10,000 volts in such operations, like the one I discussed with a customer recently.

The separation of the non-conductive surfaces (like when this plastic film is unrolled) is capable of generating an incredible amount of static charge. Here are two examples showing 12,400 and 16,900 volts.

One of the best ways, in industry, to dissipate a static charge is to use ionized air.  There are different methods of doing this; one of the most popular is to effect a Corona discharge, via a high voltage, low amperage electric current.  This is precisely what EXAIR’s Static Eliminators provide: a Corona discharge produces a bulk of both (+) and (-) ions in the enormous volume of high velocity air flow generated.  When these (+) and (-) ions flow onto a surface charged with (-) and (+) ions, they cancel each other out, leaving a net neutral charge.  Static, eliminated!

THE best way to accomplish this is the EXAIR Super Ion Air Knife.

From small bottles to wide films, EXAIR Super Ion Air Knives come in a variety of lengths to meet the needs of most any static dissipation application.

By combining an Ionizing Bar with a Super Air Knife, as Super Ion Air Knife provides rapid static elimination AND blow off of any dust, chips, or debris that was being statically held.  The laminar curtain of ionized air not only maximizes the rate of static dissipation, but is also ideal for stripping/sweeping away any debris, leaving a clean, static-free surface.  No more jamming, tearing, nuisance shocks to operators, dust attraction, or any of the other host of problems associated with static electricity.
