The Case for The Ion Air Gun to Eliminate Static

EXAIR manufactures a range of Static Eliminator products that are all efficient, effective, and easy to use…none more so than the Gen4 Ion Air Gun. Consider:

  • It’s “plug and play,” all the way.  Connect the cable to the Power Supply, and hook it up to your compressed air system, and you’re ready to go.
  • It’s efficient and quiet.  The high velocity jet entrains an enormous amount of air from the surrounding environment, where it’s ionized and ready to eliminate static charge quickly and effectively.
  • Instant static dissipation, at your fingertips (literally) – squeeze the trigger to blow ionized air, anywhere you want (well, within the reach of the 10 foot cable, anyway.)
Model 8493 Gen4 Ion Air Gun Kit comes with everything you need, right out of the box. Just add compressed air.

Again, the Gen4 Ion Air Gun is just one of our Static Eliminator products.  How do you know if it’s the right one?  The selection of many EXAIR Intelligent Compressed Air Products comes down to the size & shape of the air flow that will solve the application.  Static Eliminators are no different.

  • If you need to treat a large surface, you might be looking for a Gen4 Super Ion Air Knife.  They come in lengths from 3 inches to 9 feet long, and blow a laminar, even curtain of ionized air that’s extremely effective and fast at static elimination, even at very low supply pressures.
  • Gen4 Super Ion Air Wipes blow a 360° ionized airstream for pipes, cables, extruded shapes, etc.
  • Gen4 Ion Air Cannons and Gen4 Ion Air Jets are made to mount in place, and blow a focused, conical flow of ionized air.

If you’ve got large areas, multiple surfaces, or complex geometries to contend with, one (or an array) of these products might be the solution.  For a simple, straightforward, hand held static elimination solution, though, it just doesn’t get any easier than the EXAIR Gen4 Ion Air Gun.  Call me to find out how you can get one today.

When to use Compressed Air Receiver Tanks (and More)

I was recently working with a process Engineer at a food packaging plant on installing a Super Air Knife to blow excess water off a food product. This product was moving single file on a conveyor belt with about 6 feet between each product. The belt was moving pretty slow so we wanted to turn the air knife on only when the product was in front of the knife, which saves compressed air and energy. To do this we used the ELECTRONIC FLOW CONTROL (EFC). If the knife ran the entire time it would be wasting any air blowing during one of the 6′ long gaps. This would also put an unnecessary strain on their already taxed compressed air system. The EFC let him only supply air to the Knife when it saw a product on the belt.

This application worked perfectly, but they had one other issue. Throughout the day it seemed as if they were losing compressed air pressure at the knife. What they found was during peak compressed air usage in the plant the compressor couldn’t keep up with the demand. Fear not, the Super Air Knife was only running for 7 seconds and was off for 20 seconds. This was a perfect application for EXAIR’s Receiver Tank.

Receiver Tanks are great for applications that require an intermittent demand for a volume of compressed air. This can cause fluctuations in pressure and volume throughout the compressed air system with some points being “starved” for compressed air. EXAIR’s Model 9500-60 60 Gallon Receiver Tank can be installed near the point of high demand so there is an additional supply of compressed air available for a short duration. The time between the high volume demand occurrences should be long enough so the compressor has enough time to replenish the receiver tank.

If you have a process that is intermittent, and the times for and between blow-off, drying, or cooling allows, a Receiver Tank can be used to allow you to get the most of your available compressed air system. If you need any assistance calculating the need for a receiver, please let us help.

Note – Lee Evans wrote an easy to follow blog that details the principle and calculations of Receiver Tanks, and it is worth your time to read here.

Custom Products from EXAIR Meet Your Specifications

Since EXAIR manufactures and distributes our own products, we have the flexibility to provide custom products, special processing, unique packaging and more. If your process or specifications are something special, let us know and we will do our best to accommodate any special considerations you might need. Following is one example for a customer who purchases air guns.

Several months ago I received a call from a company that was looking for a specialized air gun.  This company was involved in the servicing of highly specialized measuring equipment and needed a safe, quiet, & efficient air gun that also had to be completely oil/contamination free.   This was to ensure no contamination would result from using the air gun on any of their equipment.  Ultimately this meant that every air gun component needed to be washed,  rinsed and dried to ensure there was no residual oils or dirt from manufacturing left on or in any component of the gun.

Our customer decided on the highly versatile Vari-Blast Compact Safety Air Gun with the award-winning Nano Super Air Nozzle, specifically models 1698SS and the 1698SS-6.  EXAIR presented a written process to the customer. This process explained how we would identify and manufacture their specific air gun in order to assure the customer that would receive a consistently clean air gun, every time.

Compressed Air Use in the Aerospace Industry

EXAIR’s products have been used for a very large selection of applications in almost every industry.  Today I want to highlight a few that pertain to the Aerospace Industry.

First – a quick lesson on how to access the Applications database– Be sure to Register and then Log In

From the main page, hover the mouse pointer over ‘KNOWLEDGE BASE‘ and the pop-up menu will appear as seen below.  Select ‘APPLICATIONS’ Website Applications.png

On the left hand side of the screen you will see a gray navigation pane that shows Application with a list underneath.  Scroll down the main page and you will see a second heading in the navigation pane labeled “Industry”.  You can select your industry from the list provided.  For today’s example we will select Aerospace.

Industry_App_Database
The Industry section of the Application Database is found on the left hand side of the screen in the navigation pane.

Once the industry is selected there will be a new list of applications that are displayed in the center of the page.   Simply select the application you would like more information on and the details will display.

Below, we showcase the application from a machine manufacturer for the Aerospace industry.   This customer manufactured the production equipment of a flexible, porous material that is continuously passed through a wash tank prior to cutting to length.  They were interested in speeding the drying process of this strand, and considered blowing hot air onto it.  It was not feasible to install an electrically powered hot air blower or gun.  They needed an air flow of approximately 15 SCFM at 200°F, and had 70 psig air supply with a large volume available.  They utilized a Vortex Tube installed over the strand after it exited the dip tank.   The Vortex Tube was oriented with the hot air exhaust blowing on to the strand to dry the strand.  The customer stated that they not only met their expectations but exceeded the original hopes and were able to dry the product quicker and safer than expected.

Vortex_Tube_Drying_Material
Selecting any of the listed applications in the center of the screen will display the details of that particular application.

This is just one of many applications that are showcased in the Application Database for the Aerospace industry.   Those are just a small sampling of the thousands of applications that can be researched through the database.  If you would like to share your application to the database, feel free to contact an Application Engineer.

Types of Air Amplifiers: Amplify Volume or Amplify Pressure

EXAIR Air Amplifiers use a small amount of compressed air to create a tremendous amount of air flow.

As Application Engineers, we help many customers with finding solutions with effective, safe, and efficient EXAIR products.  But, in some instances, we get a request for an air amplifier to increase line pressures.  EXAIR does not manufacture this type of Air Amplifier.  In doing some research on the internet, I was able to find two different types of air amplifiers.  In this blog, I will describe the difference between the pressure-type and volume-type.

The EXAIR Super Air Amplifiers are defined as a volume-type of an amplifier.  They use compressed air to generate a large volume of air flow.  The amplification ratio is the comparison between the inlet air flow and the outlet air flow.  With the EXAIR Super Air Amplifiers, we can reach an amplification ratio of 25 to 1.  They use a Coanda profile with a patented shim to create a low pressure to draw in a large volume of the surrounding air.  EXAIR manufactures a variety of different sizes, materials, and types.  But they all do the same thing, amplify the volume of air.  To give an example, model 120024 Super Air Amplifier has a 25:1 amplification ratio.  It uses 29.2 SCFM (826 SLPM) of compressed air at 80 PSIG (5.5 bar).  So, the outlet air flow is amplified from 29.2 SCFM to 730 SCFM (20,659 SLPM) of air.  This large volume of air works great for cooling, exhausting, and transferring.  But, with any type of amplification, you have to lose something.  With the volume type Air Amplifiers, the outlet pressure is reduced dramatically.

The pressure-type air amplifiers are different from the Super Air Amplifiers as this device will amplify the outlet air pressure, not the volume.  It is an air pump that has a direct dual piston that uses two different diameters.  The larger diameter uses the drive inlet pressure while the smaller diameter is used for the boost pressure.  The amplification ratio is determined by the difference in volume from the drive piston to the boost piston.  They also come in a variety of ranges and sizes.  As an example, an amplification ratio of 15:1 will increase an inlet pressure from 100 PSI (7 bar) to an outlet pressure of 1,500 PSI (103 bar).  Since the pressure-type air amplifier is an air pump, the system has to cycle.  To do this, they use pilot valves to either add the inlet compressed air to the drive piston or to relieve the air pressure from the drive piston.  This cycling portion of the operation does reduce the efficiency of the air amplifier.  The pressure-type air amplifiers are used to generate high pressure for a specific application or area and eliminate the purchase of a high-pressure air compressor.  The applications include air clamps and presses, pressure testing, air brakes, and also blow molding.  Like stated above about losing something with amplifications, the volume of air is reduced dramatically.  Generally, a reservoir tank and over-sizing will be needed for a good system.

The Application Engineers at EXAIR enjoy talking to customers about compressed air applications.  If you need more information about Air Amplifiers, you can contact us directly.  We can explain the volume-type that we manufacture or refer you to a company that makes the pressure-type.  Either way, we will be happy to hear from you.

Eliminate Static in Tight Spaces with EXAIR’s Gen4 Ion Air Cannon

The lower relative humidity associated with the cold, dry air of winter results in a significant increase in calls related to static problems. Luckily, EXAIR has a wide-range of Static Eliminators that are designed specifically to address static issues in a variety of industries. 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. This gaining/losing of an electron causes the atom to be electrically imbalanced.

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. Our Gen4 Static Eliminators have 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.

One of these such products is the Gen4 Ion Air Cannon. EXAIR’s Gen4 Ion Air Cannon neutralizes static charges at distances up to 15 feet without any moving parts. Utilizing EXAIR’s 2” Super Air Amplifier, the Ion Air Cannon will maximize ionized airflow while minimizing compressed air consumption. The strong, concentrated, quiet, and efficient ionized air is capable of eliminating a 5kV charge in as little as .37 seconds.

The compact design saves space and allows it to be mounted in confined areas on walls, machine frames, bench tops, etc. The stand is pre-drilled for easy mounting, and incorporates a swivel adjustment to precisely position the airflow. Some examples of applications that have required the assistance of an Ion Air Cannon include: removing static from motorcycle bodies prior to painting, static removal on PCB boards, and disposable diaper manufacturing.

With a wide variety of Static Eliminating products available from stock, don’t wait for your static problems to subside when humidity levels come back up in the spring. Get yourself a Gen4 Static Eliminator from EXAIR and make sure you’re able to operate, static-free, for the rest of this winter and in the subsequent seasons to come!
