Super Ion Air Wipes – Eliminate Static on Wire, Cable, Extrusions

Gen4 Super Ion Air Wipe

As the colder dryer months are upon us, static electricity will be more frequent and will become a real nuisance.  Machines will start jamming, alignments will be difficult, dirt will collect to surfaces, and hazardous sparks can shock personnel.  EXAIR manufactures a line of Gen4 Static Eliminators to remove this nuisance.

EXAIR manufactures eight different product lines in two different styles within our Gen4 Static Eliminators.  In this blog, I will be covering the Super Ion Air Wipe.  This product blows ionized air in a 360-degree pattern.  They are engineered to remove static and debris from the outside of hoses, plastic pipe, extrusions, and coated wires.  With a split design, the Gen4 Super Ion Air Wipe can easily mount around the product without having to re-thread.  EXAIR stocks two different sizes with a 2” (51mm) and 4” (102mm) inside diameter. The Super Ion Air Wipes give a fast static-decay, a shockless and non-radioactive design, variable flow and force, low air consumption and no moving parts.

8462 Super Ion Air Wipe Kit

The Gen4 Super Ion Air Wipe can be purchased as a kit which will include the power supply (required for ionization), a filter separator (to clean contamination from the compressed air), and a pressure regulator (to control the blowing force).  The filter and regulator are properly sized to avoid any air flow restrictions or loss of performance which can occur when using components which are not suited for the application.

Static

Generally speaking, static is generated from non-conductive surfaces being “rubbed”.  This could be from going over rollers on a conveyor, stacking product onto each other, sheet feeding, and even peeling away a backing material.  When non-conductive surfaces, or insulators, are moved or separated, electrons are “stripped” and redistribute on to different areas of the surface.  Static charges are typically measured in kilovolts (kV), or 1,000 volts, and they can be either positive or negative.  The higher the charge, the stronger the static force.  In reference, at 10 kilovolts, a spark can jump one inch (25 mm) from the surface.   EXAIR offers a Digital Static Meter, model 7905, to measure the amount of static voltage on a surface.  It is a great tool for finding problem areas in your process as well as determining the effectiveness of the treatment.

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.

These ionizers are powered by a 5,000V AC power supply.  The alternating current, AC, will create both negative ions and positive ions.  So, no matter the polarity of charge on the surface, the Gen4 Static Eliminators will be able to remove it.  The power supplies come in either a 2 port or 4 port design so you can power multiple Gen4 Static Eliminators with one power supply.  The input power is selectable from either 115VAC or 230VAC in both 50/60 Hz.   Two armored and electromagnetic shielded cables connect the Super Ion Air Wipe to the power supply. This will help to protect the cable from abrasions, cuts and splits which can be common in rugged industrial areas.

Static can be a real nuisance with shocking operators, “sticking” debris, and jamming processes.  If you run into these issues in your application, no matter the shape, EXAIR has a Gen4 Static Eliminator for you.  Even if you have cylindrical objects like tubes, pipes, hoses and extrusions; EXAIR can provide the Gen4 Super Ion Air Wipes in stock.  For more information, you can contact one of our Application Engineers at EXAIR.

The Gen4 Super Ion Air Wipe uses a small amount of compressed air to entrain high volumes of ambient air. Two shockless ionizing points powered by our Gen4 UL Component Recognized 5kV Power Supply fills the air stream with static eliminating ions. That airflow impacts the surface of the material running through the air wipe and neutralizes the charge.

The Gen4 Super Ion Air Wipe, which compliments EXAIR’s complete line of Gen4 Static Eliminators, has an aluminum construction that is lightweight and easy to mount using the tapped holes provided. Two sizes include a 2 inch (51mm) diameter and a 4 inch (102mm). There are no moving parts to wear out. Visit EXAIR.com to see the entire Gen4 Static Eliminator product line and 1/2 inch through 11 inch Super Air Wipes for applications without static.

Super Air Wipe Vs. Block Type Air Wipe

Air Wipes, which provide 360 degree blowoff, are typically used to remove heat, liquid, debris or static from wire, cable, pipe, tube, or extrusions.

We had a customer that was using a block type Air Wipe from a competitor to remove water from an extrusion.  These air wipes are built using a plastic material, typically with some additional ceramic insert to resist abrasion of the wire, the halves are hinged with air holes drilled into each half which carries air through the block and on to the wire. They were using these block air wipes on several lines. The interesting point of this blog is that it required 5 block type air wipes to equal the results of 1 EXAIR Super Air Wipe.

Since EXAIR’s Super Air Wipe equaled the performance of 5 of the competitors it consumed less air was less expensive and produced less noise.  Also in space sensitive applications the EXAIR Super Air Wipe is much thinner than the block type.  To highlight this the Super Air Wipe is 1.13″ thick on all 11 models that range from 3/8″ to 11″ throat diameter.   The performance of the block air wipe can only be changed by altering the inlet air pressure while the EXAIR Super Air Wipe can also be changed by adusting the inlet air pressure OR by adding an additional shim the force can be nearly doubled!

Many of these block type air wipes use a series of holes to direct the compressed air supply at an angle over the material that needs to be cleaned off.  EXAIR’s Super Air Wipe being an engineered compressed air product use’s fluid dynamic’s to create more force as demonstrated below. The air from EXAIR’s Super Air Wipes is a continuous 360 degrees, without the gaps a series of holes creates.

How The Air Wipe Works

Compressed air flows through the inlet (1) of the Air Wipe into the annular chamber (2).  It is then throttled through a small ring nozzle (3) at high velocity.  This primary airstream adheres to the Coanda profile (4), which directs down the angled surface of the Air Wipe.  A low pressure is created at the center (5) inducing a high volume flow of surrounding air into the primary airstream.  As the airflow leaves the wipe, it creates a conical 360° ring of air that attaches itself to the surface of the material running through it (6) uniformly wiping the entire surface with the high velocity airflow.

Block type air wipes are generally available in standard sizes up to 7″ in diameter while EXAIR’s Super Air Wipes are available in stock diameters up to 11″ and we also offer custom sizes to suit many other applications.

If you have any items that need to have a 360 degree blowing pattern, I would enjoy hearing from you…give me a call.

The Case For The EXAIR Super Air Wipe

If you’ve ever used an air gun to blow something off, you’re familiar with the cleaning ability of compressed air.  If you can get the whole object blown off from where you’re standing, there really is no substitute…but what if you need to get to the other side…or sides?

Even if your product is not on fire, you probably wouldn’t want to “limbo” under it with an air gun…

This is where the EXAIR Super Air Wipe comes in…they allow you to blow a continuous, uniform 360° air stream, all around your product.  Consider their benefits:

*Sizes: the Super Air Wipe’s compact ring design means it won’t take up a lot of room; you just need a few inches, in any direction, to install one.  We stock them in eleven sizes, from 11″, all the way down to our brand-new 3/8″ diameter.

*Durability:  All EXAIR Super Air Wipes are assembled with stainless steel shims and hardware.  Models up to 4″ come with a rugged, stainless steel wire braided hose, connecting the two halves for compressed air supply.

The aluminum Super Air Wipe is available in 11 sizes; the stainless steel Super Air Wipe comes in 5 sizes…all from stock.

*Ease of installation:  Smaller sizes can be supported by the compressed air supply line, if a pipe is used and threaded into the connector hose’s 1/4 NPT port.  Larger sizes can likewise be adequately supported with pipe to both halves. All models have a bolt circle of 1/4″-20 tapped holes for more permanent and rigid mounting.  The split ring design is another key feature:

Simply open the two halves, and clamp them around your product…no threading!

*Corrosion resistance: Depending on the environment in which the Super Air Wipe will be installed, we offer them with aluminum (3/8″ – 11″ sizes) or stainless steel (3/8″ – 4″ sizes) bodies.

*Temperature rating: Aluminum Super Air Wipes are good to 400°F (204°C) and stainless steel models are good to 800°F (427°C.)

*Range of operation: We install a 0.002″ thick shim in all stock Super Air Wipes; this is suitable for a wide range of typical industrial/commercial blow off applications…a Pressure Regulator can then be used to “dial in” the air flow precisely to meet specific needs.  If a job calls for higher force & flow, additional 0.002″ shims can be installed.  Shim Sets come with the Super Air Wipe Kits, or individual shims can be ordered separately.

*Performance: Before the Super Air Wipe, a ring of nozzles was commonly used.  In fact, they still are, but we’re trying to fix that, at every opportunity we come across.  Problem with those is, it’s hard to get an even air flow all around, which leads to inconsistent blow off.  They can also be loud & inefficient, as we’ve found in numerous Efficiency Lab tests and Case Studies, like this one…

These wasteful and loud modular plastic tube blow offs…
…were replaced with EXAIR Super Air Wipes. 24 such replacements netted the customer an annual compressed air cost savings of over $13,000.00.

…and this one…

Implementing a Super Air Wipe salvaged a $30,000 job for this customer. Click on the picture to read all about it in our Case Study Library (registration required.)
