EXAIR Helping the Medical & Pharmaceutical Industries

EXAIR designs, manufactures, sells and supports many Intelligent Compressed Air® products influencing many industries round the world. I have personally talked to many manufacturing companies needing our products and want to focus on just a few applications that I helped within the medical industry.

Air Knives: Our Air Knives are very versatile and generally used to cool, dry, and clean products and processes. The most recent application I had using our Super Air Knives in the medical field was using a compilation of knives strategically arranged to blow moisture off stainless steel tubes which are components af a larger medical product.

Cold Gun: Our customer in the pharmaceutical industry was experiencing downtime and low efficiency rates as the tablet punch presses for their pill manufacturing lines were heating up and causing downtime. The solution was placing a couple Cold Guns blowing cold air on to the punch presses to remove the heat. The end result was higher efficiency rate and little to no downtime from the punch presses over heating.

Intellistat Ion Air Nozzle: The Intellistat Ion Air Nozzle has been used in clean room applications. These have been used most commonly to keep contaminants away from packaging and labeling areas. The Intellistat Ion Air Nozzle has a clean room classification: ISO 14644-1 Class 5, operational.

These are just a few examples how EXAIR helps in the medical industry. If you have questions or want to discuss a specific application and need help determining the best EXAIR product for you, please contact any of Applications Engineers as we are ready to help.

Gen4 Super Ion Air Knife Cleans Art!

I took a phone call recently from an artist who applies thin colored films to glass sheets. He then uses several panes of that colored glass to build beautiful simplistic art installations! They are so clean and clear every angle you look through you get a different color and view you wouldn’t expect. But he was having a problem, these sheets of glass were building a large static charge and making every bit of dust and dirt stick to the surface. They were spending countless hours painstakingly cleaning every panel of glass because one spec of dirt would ruin the end goal.

Colored Glass Walk Way

Originally they called in to look at the Super Air Knife, which is good to remove dirt, dust and debris – but does not eliminate static if that debris were to be held on to the glass with static. His idea was to poor water on the glass then use the Super Air Knife to blow the water off, messy but they were hoping to kill two birds with one stone. Getting rid of the static and cleaning the glass all at once. He was excited when I told him about out our GEN4 Super ION Air Knife! It would have the ability to neutralize the static charge and blow away any debris clinging to the surface.

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 a web, 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

How The Gen4 Super Ion Air Knife 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.

Static Solutions for Clean Rooms and Controlled Environments

Clean rooms and controlled environments are a critical spaces for manufacturing, testing or scientific research under conditions which require less contamination from the environment. They have a low or controlled level of pollutants such as dust, other airborne particles, or chemicals. They may also limit specific materials from even entering the room. Many clean rooms work by providing a positive pressure inside the room and filtering the air entering the room. This positive pressure pushes contaminated air out of the room and the filters clean up any air moving into the room. Many controlled environments have specifications on humidity levels, maximum values for static charges, maximum values for the size of particles allowed in the air, temperature, and what materials are prohibited to enter.

With the patented and award winning Intellistat Ion Air Gun and the NEW patented Intellistat Ion Air Nozzle, we have the perfect solution for these scenarios. These are intelligent compressed air® products that create and utilize ionized air to eliminate static and remove troublesome particulates in clean rooms and controlled environments. Using a minimal amount of compressed air, and having a precise blow off pattern, each of these products can reduce static form 5000 volts, to less than 500 in under 1 second. These Intellistat products are balanced to minimize a static charge to +/- 30V, and can be used to eliminate static on some of the most sensitive electronics.

Both of these products are rated Class 5 for Clean Rooms and controlled environments per ISO 14644-1. They are also OSHA compliant for noise and dead end pressure. Other features of both products include a 6mm air connection, and a red and green LED light to signify the ionized air is being produced.

As you can see in the opposing pictures, the differences lay in the delivery system of the Ionized Air. The Intellistat Ion Air Gun offers a short throw, fast acting, and effortless trigger so that the end user can point and shoot the static away. The Intellistat Ion Air Nozzle comes with a compact Stainless Steel adjustable mounting bracket to provide hands free operation. An easy on and off switch on the top is activated and away goes the static.

Please let me know if you have questions, or would like to put these amazing tools to work in your Clean room or other application.

Thank you for stopping by,

Super Ion Air Knives Remove Static From Coil Stock for Metal Food Packaging Manufacturer

Here on the EXAIR Blog you’ll often find a host of applications and discussion centered around static electricity during the fall and winter months. The reason for this is that during periods of lower humidity, it’s much easier for static to build up and pose problems for a variety of industrial processes. During the summer, higher levels of humidity “coat” the atoms of a molecule and reduce the amount of static buildup.

With that being said, just because it’s right in the middle of summer where humidity levels are rather high doesn’t mean all static problems go away. Some applications generate such a high level of static that they require a solution year-round. Such was the case for a recent customer that manufactures a wide variety of various styles of cans and cups used by the food industry.

For a new process for one of their customers, they apply a wax to the coil stock using an electrostatic waxer in front of their cupper lines. The waxers run at -20Kv to charge the atomized wax particles to attract to the positive charge on the coil stock. The coil stock then carries a residual charge as high as 18Kv and in less than a minute would immediately cling to their cupper die press. Without a solution for removing the static, they were unable to run this machine.

Model 112036 SIAK

The coil stock width ranges from about 33-34” and carried a charge on either side of the material. The recommended solution was to install (2) of our Model 112036” Super Ion Air Knives just in front of the material’s entry into the cupper die on top and bottom of the coil stock. They were up against a firm deadline to get material completed and to their customer. A delay in other components had pushed them right up against their commitment to deliver finished cans to their customer, something we’re all becoming all to common with nowadays.

Fortunately for them, EXAIR had the parts available and in stock. We shipped them out the very same day for next day early AM delivery. They had them up and installed before lunch and production was resumed. At a time where it seems everything is out of stock for a number of reasons, EXAIR is still shipping orders out same day. If you need a solution, and you need it fast, give us a call.
