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.

EXAIR Case Study Library: Help Me Help You

EXAIR Corporation has a broad range of resources to aid in the selection of the right product for the right application:

If you’re a regular reader of EXAIR blogs, you’ve seen a number of “brags” on the successful implementation of just about all of our products. Another “more” part of our website is Applications, where you’ll find WAY more brief summaries of EXAIR Intelligent Compressed Air Product successes than we can fit in our catalog. These come from conversations, emails, and oftentimes shared photos or videos between EXAIR Application Engineers and our customers. We get to write those up as examples of our products making things better. On the occasions where the customer is willing to work with us to quantify how MUCH better our products have made things, we’re able to do a Case Study. A typical Case Study involves collection of “before/after” data, quantifying the benefits of using EXAIR products. This can include, but is not necessarily limited to :

  • Compressed air consumption
  • Noise level
  • Safety (OSHA compliance)
  • Performance improvements
  • Product durability/longevity

At last count, there are over forty entries in our Case Study Library. You can search these by Product, or by Application…depending on what, specifically, you’d like to know. Registration (free and easy) is required to access our Case Studies…if you’re already registered & signed in, you can read the details on any of them. For your immediate viewing, though, here are the pertinent details on just a few:

“Before/After” photos of this efficient and quiet upgrade.
  • More durable and efficient Safety Air Guns: This customer’s main concern was the durability of the air gun they were using. This was a situation where they sent one in for Efficiency Lab testing (that’s one of the ways we can help collect “before” data for a Case Study). I did this one, and the customer’s air gun’s trigger BROKE WHILE I WAS TESTING IT. In addition to providing a more durable product (a Model 1310 Heavy Duty Safety Air Gun, specifically), it also reduced the compressed air consumption from 63.5 SCFM to 14 SCFM, and the sound level dropped from 89.9dBA to just 74dBA.
EXAIR Safety Air Guns: rugged construction, quiet & efficient performance.

So, back to the title of this blog…how can you “help me help you” with a Case Study? Let’s start with that 2nd part. Upon successful completion of a Case Study, I can “help you” with a credit on the order you placed for the EXAIR product(s) that replaced what you were using before, or a discount on a subsequent order…if, for example you got a Super Ion Air Knife to try out on one of your headlight making machines, and it worked so good you want to put them on the other nine machines (true story).

The “help me” part is pretty easy too. If you have instrumentation (air flow meters, sound level meters, etc.) to gather the “before” data, we can use that for the Case Study. If you don’t, we do. You can send the subject devices in for Efficiency Lab testing…our engineering staff will use calibrated test equipment to work up a detailed performance profile on what you send in. It’s a free service we offer to anyone who wants this data, in fact, and Efficiency Lab testing has no effect on the credits or discounts we offer for participation in a Case Study.

I also “help you” (and “help me”) by keeping your name, and your company’s name, off the Case Study. That way, if your process or product is proprietary in nature, we don’t risk sharing your hard earned success with your competition. We also don’t run afoul of the authorities, like this one last Case Study I’m going to share, where a machine shop was blowing off parts they make for the military that are classified in nature. They had crimped copper tubing pointed at the cutting tool, and it worked…it was just loud and wasteful. They zipped the crimped ends off and installed Model 1100 Super Air Nozzles with a simple compression fitting. Had the photo below shown the machined part in the lathe chuck, “we’re ALL going to prison” according to the customer:

One well-cropped photo made for a great Case Study, and nobody had to go to prison. THAT was a good deal.

This one, by the way, saved 2.7 SCFM per nozzle (over $840.00 a year in compressed air savings), and reduced the sound level from 96dBA to only 76dBA.

EXAIR Intelligent Compressed Air Products have been making things better for compressed air users for almost forty years. If you’d like to find out how MUCH better we can make things for you, give me a call.

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.

More And More Award Winning Products From EXAIR

As you might expect, a LOT of things have changed at EXAIR Corporation since 1983. Most of our current senior management had yet to graduate high school, and a fair number of current employees had yet to BE BORN. According to our computer system (another BIG change since 1983), our first ten customers were here in southwest Ohio (#11 was in Michigan), and now, we sell direct across the US & Canada, and our worldwide distributor network offers representation on six continents. One thing that hasn’t changed, though, is our founder’s vision of manufacturing quiet, safe, & efficient compressed air products for process improvement in just about any industry that uses compressed air. And THAT, dear reader, continues to gain high profile attention. The photo above shows the seven awards that our products have recently won, which were announced in 2021 or early 2022. Here’s a rundown:

  • A supplier of fiberoptic parts uses an Intellistat® to remove dust and static charge from product prior to packaging.
  • A medical device manufacturer has one in a Class 7 clean room for silicone parts cleanliness.
  • A nutritional supplements maker uses their Intellistat® to remove static charge & powder residue from the tops of plastic bags before sealing them. The excess/residual powder causes them not to seal correctly.

Machine Design 2021 Big Idea! (Electrical Components) BRONZE AWARD
Gen4® Static Eliminator Power Supply

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.

EXAIR Static Eliminators produce ionized air via a Corona discharge, which requires high voltage, low current electricity. The Gen4® Static Eliminator Products feature armored & shielded cables with an internal ground, for safety and reliability. The ground path is completed through the cable and the Power Supply port, eliminating the need for an external ground connection. Faults in external ground connections result in the majority of the problems with those devices, so the internal ground is a “Big Idea!” indeed. The Gen4® Static Eliminator Power Supplies are switchable for 115VAC or 230VAC voltages, and are offered in 2, or 4 outlet designs, which can power any 2, or 4 EXAIR Static Eliminator Products. Like most EXAIR Intelligent Compressed Air Products, they’re used for a wide range of applications, in a wide range of industries:

If you’d like to find out more about these, or any of our other engineered compressed air products (we’re pretty proud of them all), give me a call. I can talk about them all day long…and sometimes I do!
