Static Elimination For Cleanrooms: The Intellistat Ion Air Nozzle

Published on by Russ BowmanLeave a comment

Cleanrooms (sometimes written as two words: “clean rooms”, and historically called “White Rooms” or “Dust-Free Rooms”) are engineered spaces where specialized equipment and procedures are used to maintain a very low concentration of contaminants. While certain levels of cleanliness are desirable for many processes, certain ones can be catastrophically affected by contamination. In the 1960’s, a physicist working for Sandia National Laboratories named Willis Whitfield pioneered the modern cleanroom. His designs focused on continuous filtration of the air inside. This was a real game changer for a number of industries like electronics, pharmaceuticals, semiconductors, and all kinds of scientific research facilities. They can be small – like a dedicated enclosure in a larger building or shop where one or two people perform benchtop testing, assembly, etc. They can also be enormous, like one of the earliest cleanrooms: a 70,000 square foot space at an RCA facility not far from here, in Cambridge, Ohio, where they made control equipment for some of the earliest intercontinental ballistic missiles in the U.S. military’s arsenal.

It should come as no surprise that equipment used in cleanrooms must comply to some demanding standards & specifications. To that end, ISO (The International Organization for Standardization) created ISO Standard 14644-1. It identifies nine Class Numbers, based on allowable particulate concentrations in a given volume of air. Here’s how it breaks those down:

Basically, the lower the Class Number, the cleaner the air. ISO 1 is often used in semiconductor manufacturing. Medical device manufacturers and pharmaceutical facilities typically specify ISO 5 & 7.

Equipment used inside a cleanroom must be designed, and operated, so as to not increase particulate concentration limits above these limits. You wouldn’t want to use steel tools that are prone to rust, or electric tools with carbon brushes in the motors, for example.

EXAIR’s Intellistat Ion Air Nozzle was designed with these considerations in mind. They were tested by a third part independent laboratory and are classified for use in ISO Class 5 (or below) cleanrooms. This has made them especially popular in pharmaceutical laboratory use, as well as:

  • A local eyeglass & camera lens manufacturer uses them to ensure precision measurement instruments’ readings aren’t affected by any residual static charge caused by the grinding process.
  • A company that makes overlays for medical devices (IV pump controllers, patient monitoring devices…pretty much anything with pushbuttons you might find in a hospital room or a doctor’s office exam room) uses them to maintain compliance with their customers’ standards.
  • A number of food production facilities around the country use them to remove static from processed foods, and packaging containers, during filling operations.
  • A manufacturer of packaging machinery includes them on filling machines servicing the food and pharmaceutical industries.
Order before March 31, 2025 and receive a FREE AC Sensor with any qualifying Static Eliminator purchase.

Whether they’re in a cleanroom or not, the compact design, ease of installation & operation, air use efficiency, and quiet operation make them ideal for a range of static elimination applications. If you’d like to find out more the Intellistat Ion Air Nozzle (or its handheld version, the Intellistat Ion Air Gun), give me a call.

Static and Variance

Published on by Brian FarnoLeave a comment

Okay, folks, it is time we seriously discuss how dry it is here in the MidWest right now and how much static there is anywhere we go. The dry air is the lack of moisture due to heat being used inside facilities, and thus, the static ramps up. If you didn’t understand much of those statements then it is okay, we have a whitepaper that covers the basics. The seriousness of the static in my home has reached critical mass. We are past the funny shocks and hair standing on the end humor side of static. We have reached a critical mass where it is no longer funny, my coffee is being affected by the ambient level of static charge.

That’s right, the coffee grinder I received for Christmas is riddled with static. Now, it is still functioning, thank goodness for that. The container that houses the fresh ground, the nectar of the gods making crushed beans, is made of polycarbonate material and is prime to hold a static charge. As the dry coffee beans are ground into obliteration there is a tremendous amount of friction which causes a very high charge on the ground bean discharge that goes into a very dry non-conductive container. This means the grinds all pile up and then also cling to every single surface on the interior of the small container. That’s fine, it still does not affect the performance of the grinder. Then, when I open the lid there is a detachment that happens and a small amount of that highly charged ground bean will start to dance all over the surfaces of the container, including outside of it and onto the counter. The end result is I have to constantly wipe up coffee grinds and I am wasting the grinds that give me the caffeine I intend to consume.

The dilemma here is that I don’t want to run compressed air into my kitchen, already have one project going on in the house. Secondly, my wife would not think it would be as entertaining as I would. So, I need a non-compressed air-assisted static eliminator that can plug straight into a voltage available here in the US, and let’s face it, coffee is a global consumption so 120 VAC and 230 VAC would be preferred. Enter, the VariStat Benchtop Ionizer.

The Varistat would easily mount to the wall over my coffee generation station and could be adjusted from a gentle breeze to where it doesn’t disturb the coffee grinds all the way up to a forceful blast in case the need would arise. I could also vary the balance of the unit to meet the atmospheric and surface conditions of the container.

Okay, so I’m probably not going to buy a Varistat Benchtop Ionizer and mount it to my kitchen wall. I would easily recommend it to any kind of hopper loader or regrind operation where the static is causing the materials to cling to the containers or causing nuisance shocks. This unit is easily sat on a bench top or mounted to a wall or ceiling over a hopper or workstation. Thanks to the operation of standard 120 VAC or 230 VAC it can function nearly anywhere in the world that has electricity.

If you would like to discuss coffee, what my favorite roasts are, or more importantly how can we make this work in our building, just let me know if you have some questions and we will get back to you quickly.

Press Release: New Varistat Benchtop Ionizer

Published on by Russ BowmanLeave a comment

At EXAIR, when something notable happens, our Marketing folks like to make a big splash for our customers with a Press Release. The latest one is all about one of the latest additions to our Static Eliminators Product Line: the Varistat Benchtop Ionizer.

Click above to get ALL the details!

Common topics of Press Releases include the introduction of a new product (like our 1/2 NPT Hollow Cone Liquid Nozzles for Cooling and Washing), the release of new media (like our New Air Atomizing Spray Nozzle Video), expanded certification of existing products (like the Upgraded Certification for our NEMA 4 Cabinet Cooler products), or when someone achieves a major industry-related accreditation (like when I got my Certified Compressed Air Systems Specialist certificate from the Compressed Air & Gas Institute). The Varistat is a similarly big deal, for some unique reasons:

  • It’s our first air blowing product that’s NOT compressed air operated. We do still take pride in being THE industry experts for quiet, safe, and efficient compressed air products, but with a couple of decades worth of expertise in static elimination, the Varistat rounds out our comprehensive line of Static Eliminators.
  • It’s also our first Static Eliminator with the ability to balance the polarity of ionization of the air flow. That means you can get more positive ions (and fewer negative ions), or more negative ions (and fewer positive ions). This is done by pressing the “+” or “-” polarity buttons on the top:
Blue lights to either side indicate the relative concentration of positive or negative ions generated. If none of the blue lights are lit (the green light simply indicates the unit is on), then a high concentration of both positive and negative ions is being generated.

Simple setup, simple operation…what more could you ask for? If you’d like to find out more about the Varistat Benchtop Ionizer – or any of our Static Eliminator Products – give me a call.
