The Gen4 Super Ion Air Knife is a powerful static eliminator that prevents jamming, tearing, shocks and dust build up by neutralizing static and blowing away the debris.
The Gen4 Super Ion Air Knife combines the quiet and efficient Super Air Knife with the compact design of the rugged Gen4 Ionizing Bar resulting in a total solution to remove static electricity from plastics, webs, sheet stock and other product surfaces. Removing the static helps reduce or eliminate the process issues that the static electric causes, allowing for greater production speeds, improved product quality and a cleaner product.
The Gen4 Super Ion Air Knife floods an area or surface with static eliminating ions. With a uniform airflow across its length, misalignment to critical surfaces like webs is avoided. The force can be adjusted from a light breeze, to a full out blast of air. The Gen4 Super Ion Air Knife is electrically powered, is shockless and has no moving parts.
How It Works
In the diagram above, compressed air flows through an inlet (1) into the plenum chamber of the Gen4 Super Ion Air Knife. The flow is directed to a precise, slotted orifice. As the primary airflow exits, it creates a uniform sheet of air across the entire length, pulling in in surrounding air (2). An electrically powered Gen4 Ionizing Bar (3) fills the curtain of air with positive and negative charges. The air stream delivers the static eliminating ions to the product surface (4) where it instantly neutralizes static and cleans off dust and other particulates.
The Gen4 Super Ion Air Knives are powerful tools, and very quickly dissipates 5kV of static even at low compressed air supply pressures. At 5 PSIG, only 3.7 SCFM (0.3 BAR, only 105 SLPM) of compressed air per foot of length is required!! Sound levels are also very low, resulting in quiet operation.

Many of us are familiar with what an equalizer (EQ) looks like and what it does. Unfortunately, sometimes they get a bad rap from so-called audiophiles, which in my opinion are defined individuals who spent so much money on their equipment they can’t afford to buy any music to play! Typically, they insist that tone controls must be set to flat because the sound recording engineers mastering the music have already equalized the recording to perfection and if you need to attenuate or cut certain frequencies it is an indicator of poor-quality equipment, and that is simply is not true!
Let’s consider some of the reasons why an equalizer makes sense and, in my opinion, an absolute necessity. The objects and materials in the room will change the sound reproduction characteristics of any speaker system. If you have large floor standing speakers positioned in the corners of the room, sitting directly on wood floors the speakers are now “acoustically coupled” with the floor and the walls. On the other hand, if you move the speakers away from the wall and/or place them on spikes or stands (isolating them for the floor) you would have “acoustically de-coupled” the speakers from the walls and floor, which will reduce the bass or low-frequency loudness. This all affects the perceived loudness and/or quality of the music we want to listen too.
This is where the graphic equalizer shines, no need to move the speakers around or use speaker stands or spikes. An equalizer will allow you to increase or decrease the loudness of multiple frequencies. You can completely customize your sound to suit your tastes, overcome issues with your listening room acoustics, the speakers you are listening with or even anomalies with the music recording.
Like adjusting an equalizer to suit your room acoustics, speaker size and/or speaker frequency response, EXAIR understands that the need for many different options gives you the necessary adjustments for a successful application. A few sizes of Air Nozzle, Air Jet or High Force Air Nozzles will not solve every application with the highest efficiency or effectiveness. EXAIR’s air nozzle variety allows you to produce maximum effectiveness based upon the air pressure and air volume you have available. Whether you need a strong blast or a gentle breeze, if you have tricky mounting positions or remote applications, EXAIR has the largest selection to choose from and solve your production problem.
We clearly state compressed air volume requirements in SCFM (Standard Cubic Feet per Minute) at a given operating pressure in PSI (Pounds per Square Inch), force at 12” from the compressed air outlet and the sound loudness in dBA at 3′ from the nozzle. These details provide the starting point for selecting the best air nozzle.
When you are looking for expert advice on safe, quiet, efficient, and engineered point of use compressed air products give us a call. We would enjoy hearing from you!

Just recently I worked with our Distributor in Argentina on an application for a manufacturer of bottled water. Once the bottles are filled, a protective security seal is placed along the top of the bottle. This serves two purposes, it prevents any form of tampering as well as keeps the cap of the bottle clean throughout the rest of the manufacturing process. Since most people drink directly from the bottle, this area needs to remain clean and not be exposed to contamination later on in the process.
Their problem was that static was building up on this plastic which caused an improper seal on the cap of the bottle. Further down the processing line, the bottles can be exposed to water that contaminates the bottles. They had to implement an inspection process as it was not acceptable to allow any contaminated bottles to leave the plant. Without a solution, they were losing time due to the necessary inspection as bottles were being rejected at a rate of almost 30%.
The recommended solution was to install a Model 8164 4″ Gen4 Super Ion Air Wipe just prior to the point in the process where the seal was applied. The plastic material passed through the center of the Super Ion Air Wipe which neutralized the static charge on the material. Without a charge, the seal was applied correctly and they were able to eliminate the need of a manual inspection. After installation, the reject rate dropped to 0%!!
The Gen4 Super Ion Air Wipe provides a uniform 360° ionized airstream and is available in both 2” and 4” ID sizes. Its clam-shell design makes it easy to clamp around a part for neutralizing static electricity and contaminants. The high volume, high velocity airflow attaches itself to the surface and wipes it down with static eliminating ions. The airflow stays attached to the surface and is effective up to 15’ away from where it’s mounted. It’s lightweight and easy to mount using the ¼-20 tapped holes on the back or can also be held into place with just rigid pipe.
As the temperatures begin to decline, so does the humidity in the air. Drier air results in an increase in static problems. Get ahead of it this year and check out EXAIR’s wide line of various Static Elimination products, all available to ship same-day from stock!
A manufacturer of high speed industrial machinery makes a sorting machine for seeds. There’s a clear plastic cover for operators to see the seeds as they pass through the machine. Many seeds are dense enough to move right on through, but some lower density seeds (canola, lettuce, and flax seed, specifically) bounce around a bit, and even the slight static charge that builds up as they move through causes them to cling to the inside of that viewing window.
This was a great fit for our Model 8406 6″ Gen4 Standard Ion Air Knife Kit…”fit” being the operative word. While the Super Ion Air Knives are more efficient and quieter, there simply wasn’t very much room at all for mounting inside, so the smaller profile of the Standard Ion Air Knife made all the difference in the world. Also, since they just need static dissipation of such a small area, and not much flow at all is required to blow off these lightweight seeds, the differences in compressed air consumption and sound level were not very much at all.
Recently, I worked with a production engineer at a Tier 1 supplier for the auto industry. An upcoming project was in the works to install a new line to produce headlight lenses. As a part of the process, there was to be a “De-static / Blow-off” station, where a shuttle system would bring a pair of the parts to a station where they would be blown off and any static removed prior to being transferred to a painting fixture and sent off for painting. For best results, the lenses were to be dust and lint free and have no static charge, ensuring a perfect paint result.
The customer was limited in compressed air supply volume in the area of the plant where this process was to occur. 50 SCFM of 80 PSIG was the expected air availability at peak use times, which posed a problem – the Super Ion Air Knives would need up to 105 SCFM if operated at 80 PSIG. A further review of the design parameters for the process revealed that the system needed to blow air for only 4 seconds and would be off for 25 seconds to meet the target throughput.
This scenario lends itself perfectly to the use of a Receiver Tank. Running all of the design numbers into the calculations, showed that the 60 Gallon Receiver Tank we offer, would allow for a 20 second run-time, and require 13.1 seconds to refill. These figures were well within the requires times, and would allow for the system to work as needed, without having to do anything to the compressed air supply system.
The moral of the story is – 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.
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.
