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:

Plant Engineering 2020 Product of the Year (Fluid Handling) GOLD AWARD:
1/2 NPT No Drip External Mix Air Atomizing Spray Nozzles

No Drip External Mix Atomizing Spray Nozzles

The 1/2 NPT models are the latest addition to our newest product line. The External Mix version offers the highest liquid flow rate, and largest pattern coverage. Among the applications where they’ve excelled so far are:

  • Snack food provider – applying flavoring to bulk snack materials.
  • Commercial bakery – spraying cooking oil onto pans used in a conveyor oven.
  • Sporting goods manufacturer – applying adhesive to the tops of skateboard decks to glue the grip tape on.

Plant Engineering 2020 Product of the Year (Material Handling Systems) GOLD AWARD:
2-1/2 NPT 303SS Threaded Line Vac

EXAIR's Threaded Line Vac Family
EXAIR Threaded Line Vac + Your Pipe + Compressed Air = Instant Conveyor System

For bulk material conveyance, it really doesn’t get any simpler than EXAIR Air Operated Conveyors. Stainless Steel models are especially popular when the environment – or the product – is corrosive, or hot…they’re good to 400F (204C), and can even be modified with High Temperature components for exposure up to 900F (482C). The Threaded versions have been successfully used to:

  • Recycle sprinkles applied to wafers into a return hopper in a candy production facility.
  • Replacing an auger conveyor to allow for homogenous mixing of grains & supplements in feed stock at an agricultural mill.
  • Providing a low cost solution to convey product into a hopper at a grain processing plant.

EasySwitch® Wet-Dry Vac

Like our Spray Nozzles product line, our Industrial Housekeeping Products line has also grown considerably over the years. The Deep Hole Vac-u-Gun and Heavy Duty HEPA Vac were real game changers when they came along, and the EasySwitch® Wet-Dry Vac Systems are likewise making an impact. Switching from wet to dry operation is, as advertised in the name itself, INCREDIBLY easy. Among our satisfied customers are:

Occupational Health & Safety 2021 New Product of the Year (Lab Safety) WINNER
Intellistat® Ion Air Gun™

The newest innovation in a long line of EXAIR static elimination solutions, the Model 8500 Intellistat® Ion Air Gun is made for laboratories, clean rooms, medical & electronic applications, and carries an ISO 14644-1 Class 5 rating for clean room use. Because of their rapid decay rates and lightweight construction, they’re used in a diverse range of applications and areas, including:

  • 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:

Static Eliminator Selection Example

I like jigsaw puzzles. I start with the outside…there’s something to be said for establishing the boundaries of any project…but I don’t necessarily work my way in from there. Oftentimes, a number of same-colored pieces go together quickly, and I make a little part of the big picture somewhere in the middle. If it’s a big enough picture and/or if there’s a sufficient number of pieces, I might get a few of those little parts going on, until some of them get joined together. Once that happens, the big picture develops faster & faster, and before I know it, the puzzle is solved.

As an Application Engineer for EXAIR, a jigsaw puzzle is an apt analogy for assisting a customer in selecting the right solution to an application. A recent situation proved what a good analogy this is: a caller from a custom label making shop needed to eliminate static from a bunch of thin Mylar film that was die cut into special little shapes so they could be laid out in specific arrangements. You know…like a jigsaw puzzle!

Now, there aren’t many better ways to generate a static charge than doing ANYTHING to Mylar. The magnitude of static charge created by the cutting process is downright vicious. As difficult as it was to put the first piece in place, it was IMPOSSIBLE to keep it there when they put the NEXT piece down adjacent to it. Same thing with the piece after that, and the piece after that, etc. They needed something to remove the static, and that something turned out to be an EXAIR Ion Air Knife. By installing a Model 8106 6″ Gen4 Standard Ion Air Knife along one side, they were able to gently blow a ‘whisper’ of ionized air that moved the freshly cut pieces from the die cutter’s platen so the operator could then lay them out to make the desired label design.

Gen4 Standard Ion Air Knife

So, how did we arrive at the Gen4 Standard Ion Air Knife? Wouldn’t the more efficient & quieter Super Ion Air Knife be the “go to” solution? In an awful lot of cases, it certainly is. A couple of things made the Standard Ion Air Knife more attractive here:

Profile-wise, a Gen4 Standard Ion Air Knife takes up less than half the space of a Gen4 Super Ion Air Knife.
  • Compressed air consumption: if this were an application for a continuous 36″ wide ionized air curtain in a fast moving product application with a high static charge, we’d have talked about the difference in consumption, at a high pressure (like 80psig) for the two different Ion Air Knives:
    • 36″ Super Ion Air Knife: 104.4 SCFM, or 12,528,000 standard cubic feet per year*
    • 36″ Standard Ion Air Knife: 123 SCFM, or 15,350,400 standard cubic feet per year*

*Eight hours a day, five days a week, 52 weeks a year. Assuming a compressed air cost of $0.25 per 1,000 standard cubic feet, that’s an operating cost difference of:

(15,350,400 – 12,528,000) SCF X $0.25/1,000 SCF = $705.60 per year.

  • In this case, though, it’s a 6″ Ion Air Knife, blowing a short puff of ionized air a few times a minute, at about 5psig supply pressure…anything more would blow those small mylar pieces all over the place:
    • 6″ Super Ion Air Knife: 1.85 SCFM, or 23,088 standard cubic feet per year*
    • 6″ Standard Ion Air Knife: 1.5 SCFM, or 18,720 standard cubic feet per year*

*Three 2-second cycles per minute, eight hours a day, five days a week, 52 weeks a year. Assuming a compressed air cost of $0.25 per 1,000 standard cubic feet, that’s an operating cost difference of:

(23,088 – 18,720) SCF X $0.25/1,000 SCF = $1.09 per year.

  • Sound level: again, this would be a prime consideration if they were operating at higher supply pressures. But, at the lower pressure necessitated by this application, the Standard Ion Air Knife’s 66dBA, a second or two at a time, is hardly noticeable.
  • Price: The purchase price (2021 pricing) of the Standard Ion Air Knife was ~17% less than the Super Ion Air Knife. Normally, we’ll talk about the operating cost…but not when the difference (see above) is just over a buck a year.
  • Air flow pattern: Since a curtain of ionized air was a good fit for this application, an Ion Air Knife (Super or Standard) was the logical choice. If a more concentrated flow was called for, we’d have used an Ion Air Cannon or Ion Air Jet. If they were looking for something handheld, a Gen4 Ion Air Gun or Intellistat Ion Air Gun would have been offered. For static dissipation on the entire circumference or perimeter of a part, we’d have talked about a Super Ion Air Wipe. The size & shape of the air flow, in fact, is frequently where we “start the negotiations” on product selection…sort of analogous to starting with the outside border pieces of a jigsaw puzzle!

EXAIR Corporation has a broad range of Static Eliminators, that are just one part of our diverse offering of Intelligent Compressed Air Products. If you’ve got questions, we’ve got answers…give me a call.

Static Season is in Full Swing, Super Ion Air Knives can Remove the Shock!

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.

They combine 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. Some of the issues static causes include, dirt and dust buildup on surfaces, misreads for sensors, poor quality from ink jets, poor print quality on printed surfaces, and personnel getting shocked.

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

gen4siak_hwrks_800x
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.

Added Features –

  • Compressed Air Inlets are provided on each end and the bottom of the Super Air Knife
  • Thicker shims can be installed easily if more force is needed.
  • Emitter points are durable stainless steel
  • The high voltage cable is armored to resist cuts and abrasion, and has integral grounding.  Threaded bayonet connector is fully assembled and ready to use
  • Electromagnetically shield cable protects sensitive electronics
  • Gen4 Ionizing Bars and Power Supplies are UL Component Recognized to U.S and Canadian safety standards and are CE and RoHS compliant
  • Power Supplies are 115/230 VAC selectable and come with 2 or 4 outlets
  • Standard lengths from 3″ to 108″ (76mm to 2743mm) are offered, and custom lengths are available to meet your process needs

Successful applications include web cleaning, pre-paint dust removal, shrink wrapper machinery, printing equipment, package cleaning,and bag opening/filling operations.
