EXAIR Flat Air Nozzles: Powerful, Quiet, Safe and Adjustable

Are you tired of your current compressed air being so loud? Well then, we have a solution for you; EXAIR’s Flat Super Air Nozzles. The patented design of the 1” and 2” Flat Super Air Nozzles makes it great for applications that require a powerful but precise flat stream of air. The Flat Super Air Nozzles work much like our Super Air Knives, the main difference being that the Flat Super Air Nozzles provides a more forceful stream of air. The design of the Flat Super Air Nozzles also provides a greatly reduced sound level.

2″ Flat Super Air Nozzle

EXAIR’s Flat Super Air Nozzles are safe, reliable, and efficient. The nozzles are specifically designed in a way to prevent dead head pressure as stated in OSHA Standard 1910.242(b). The directive stats that compressed air used for cleaning purposes can not exceed a dead-end pressure of 30 psig. If a dead-end pressure were to exceed that pressure then there is potential for an air embolism to form. EXAIR has designed our Flat Super Air Nozzles so that they cannot be dead-ended; this allows you to run at a typical 80-100 psig from your compressed air system.

Various Applications of Flat Super Air Nozzles

EXAIR Flat Super Air Nozzles are designed to also be quiet while operating at those higher pressures. When operating at 80 psig the 2” Flat Super Air Nozzle is going to have a sound level of 77 dBA were as the 1” Flat Super Air Nozzle when operated at 80 psig is going to have a sound level of 75 dBA. The higher the pressure the more air is going to flow through the nozzle; the more air flowing though the nozzle the louder it is going to be.

2″ Flat Super Air Nozzle

EXAIR’s High Power Flat Super Air Nozzles are designed for those tougher applications where you need more force, and will operate at slightly louder levels. The HP series Flat Super Air Nozzles have a thicker shim in them that allows for more air to escape out the end delivering a high force. The High powered 2” Flat Super Air Nozzle when operated at 80 psig has a sound level of 83 dBA where the 1” is only 82 dBA.

All of EXAIR’s flat Super Air Nozzles are designed with an internal patented shim which allows for adjusting the total volume of airflow and force that the nozzle produces. These shims are available in different thicknesses and aid in keeping noise levels down, provide gross adjustment of airflow and the flexibility for achieving a successful application. 

If you have any questions or want more information on EXAIR’s Flat Super Air Nozzles or any of our products, give us a call, we have a team of application engineers ready to answer your questions and recommend a solution for your applications.

Air Savings Calculator

I received an email from an engineer that was looking at our Super Air Nozzles.  They currently were using four blow-off lines that were made from 6mm ID copper tubes. The system was designed to blow out holes after machining.  The engineer was in charge of the task of optimizing 25 machining stations similar to this one.  He was familiar with EXAIR products from his previous employment, and he recognized the waste of compressed air by using open pipe.  He purchased four Nano Super Air Nozzle, model 1110SS, for a trial.  He was impressed with the performance, the low sound level, and the engineered design in safety.  But, for upper management in his company, he had to show a cost savings in order to change all the stations in the facility.  He asked me to help him in calculating the compressed air savings.

nano nozzle

He gave me some additional details about their application.  He was using the compressed air about 30% of the time throughout an 8 hour day at a pressure of 80 PISG.  He wanted to present the savings per day, week, and year as well as the payback period in his evaluation.  I have performed many of these calculations for other customers and was happy to help.  It is sometimes easier to speak in terms of savings, as everyone can relate to money, especially management.

Knowns:

Flow: 1110SS Nano Super Air Nozzle – 8.3 SCFM at 80 PSIG

Flow:  6mm ID copper tube – 42 SCFM at 80 PSIG

This is where the COST SAVINGS CALCULATOR on our website shines!

The Calculator tells us you will see a ROI (Return on investment) is less than 5 days! And will save you $3,033.00 over a full year on compressed air generation cost alone!

Don’t be fooled by the initial cost of a tube, pipe, drilled holes, or a substandard nozzle.  You can see by the facts above, if you use any additional compressed air in your blow-off application, it will cost you a lot of money in the long run.  If you need any help in calculating how much money EXAIR products can save you, you can use our Air Savings Calculator from our website, or you contact an Application Engineer at EXAIR.  We will be happy to help you.

Which Air Nozzle Is Right For Me?

Well, the obvious answer is, of course, an engineered air nozzle…you’re likely aware of this, or you wouldn’t be reading posts on the EXAIR Corporation blog.  We have no issue with narrowing that down a bit, and saying that the answer is an EXAIR air nozzle.  I bet you knew that was coming as well.  So let’s assume that, because of the cost of compressed air, the potential hazards of its unregulated discharge, and the flat-out racket it can make (unless you do something about it,) you’re looking for something efficient, safe, and quiet.

Now that we’re on the same page, let’s unpack that question.  The nature of the application will let us know the airflow pattern & characteristics (mainly flow & force) that we need.

For example, if you need just a pinpoint of airflow, our Atto Super Air Nozzle blows a 1/2″ diameter pattern at a distance of 3″.  Get a little closer than that, and it’s as tight as you want it to be.  Now, it’s only generating a force of 2oz (at 12″ away) but keep in mind that’s all concentrated in a small fraction of an inch diameter.  Which is plenty for most applications that need that precise of an airflow.

Atto Super Air Nozzle

If you DO need a little more flow & force, our Pico and Nano Super Air Nozzles offer incremental increases in performance.  The pattern starts to widen out, but that’s a function of the increased flow expanding in to atmospheric pressure…it has to go somewhere, you know.  But, again, the closer you get, the more focused the flow is to the centerline of the nozzle.

On the other end of the spectrum are EXAIR’s High Force Air Nozzles.  These are particularly useful for stubborn blowoff applications – a foundry blowing slag off hot strip as it cools, for example.  Our largest of these, a 1-1/4 NPT model, generates 23 lbs of force…that’s over 25 times the power of our standard Super Air Nozzle.

 

With 23 lbs of hard hitting force, this 1-1/4 NPT Super Air Nozzle is perfect for the most extreme blow off and cleaning jobs.

Speaking of the standard Super Air Nozzle, it’s the most popular answer to the Big Question.  It’s suitable for a wide range of blowoff, drying, and cooling applications, like the kinds of jobs an awful lot of folks use open end blowoff devices on.  Open ended tubes blow out a great amount of air, but they’re wasteful and noisy, and OSHA says you can’t use them unless you regulate the pressure to 30psig…where they’re not even going to be all that effective.

Choose from (top left to bottom right) 316SS, Zinc Aluminum, or PEEK Thermoplastic…whatever you need to stand up to the rigors of your environment.

If you’ve got a 1/4″ copper tube, for example, it’ll use 33 SCFM when supplied with compressed air at 80psig.  It’ll for sure get the job done (albeit expensively, when you think of all that compressed air consumption,) but it’ll be loud (likely well over 100 dBA) and again, OSHA says you can’t use it at that pressure.  So, you can dial it down to 30psig, where it’ll be marginally effective, but it’s still going to use more air than the Model 1100 1/4 NPT Super Air Nozzle does at 80psig supply pressure.  The hard hitting force of the Model 1100, under those conditions, will make all the difference in the world.  As will its sound level of only 74 dBA.  Not to mention, it’s fully compliant with OSHA 1910.242(b).  Oh…and you can even install it directly on the end of your existing tube with a simple compression fitting.

One of our customers installed Model 1100 Super Air Nozzles on all their lathe blowoff copper tubes, and saved almost $900 a year in compressed air costs.

We’ve also got engineered Air Nozzles smaller than the 1100 (all the way down to the aforementioned Atto Super Air Nozzle) and a good selection of larger ones, including Cluster Air Nozzles that hold tighter airflow patterns than similar performing single Super Air Nozzles.  They’re available in materials ranging from Zinc-Aluminum alloy, bare aluminum, brass, 303SS, 316SS, or PEEK thermoplastic polymer to meet the requirements of most any area of installation, no matter how typical or aggressive.

If you have an loud, wasteful, and likely unsafe blowoff, you owe it to yourself and everyone else who has to put up with it to consider a better solution.  Call me; let’s talk.

EXAIR Vacuum Generators and Accessories

So, you’re looking at picking out a vacuum generator for your application but don’t know what accessories you need? Well here is a little overview of EXAIR’s E-Vac system’s accessories that you have to choose from. The E-Vac has a variety of uses from pulling a vacuum on a chamber to lifting Concreate cinder blocks. Here at EXAIR we offer everything that you may need to get started; this includes mufflers, vacuum cups, hose, and fittings.

Vacuum cups for E-Vac generators

Every time I hear someone talking about trying to pick something up the first line that comes to mind is “The claaaaaaw.”. But sometimes a claw or gripper isn’t the answer for the solution; using a variety of vacuum cups one can practically pick up almost anything. We offer four different kinds of vacuum cups to choose from stock; available are small and large Round, Oval, and Bellow styles. Round cups are more suited to being used on smooth, flat surfaces. Oval cups provide the most vacuum due to the larger surface area making them ideal for lifting heavy loads. The Bellows style is best suited for textured or uneven surfaces; the folds provide a collapsible area that allows the cup to compress and seal on the uneven surface.

EXAIR’s Standard and Straight Through Muffler

Next up is the mufflers; EXAIR’s mufflers do just that, they muffle down the sound generated by the E-Vac. There are two different types of mufflers that are available; these are the Standard and the straight through mufflers. The Standard muffler is designed to be attached to the discharge end of an in-line      E-Vac and has a closed end. These are best suited for applications that are free from dust and debris. The straight through muffler is open all the way through and are more suited to applications were dirt dust and debris is present. The straight through style also offers the best sound level reduction, up to 26 dBA.

Lastly the E-Vacs have an NPT threaded connection that will allow for a suitable connector to be properly installed. From here different connectors can be used to attach the various amounts of vacuum cups. The connectors provided are Push-In Connector Type Fittings of assorted styles available with our polyurethane tubing to make the installation and plumbing a cinch.

If you have any questions or want more information on EXAIR’s E-Vacs and their Accessories. Give us a call, we have a team of application engineers ready to answer your questions and recommend a solution for your applications.

Advantages Of Compressed Air Operated Industrial Vacuums

Last week, I wrote about the benefits and advantages of the EXAIR Chip Trapper System. It’s just one workhorse in our stable of durable and reliable compressed air operated Industrial Housekeeping solutions.  All of our systems in this product line are compressed air operated, which means they offer several benefits that you don’t get with an electric powered vacuum:

  • Our air operated vacuums have no moving parts.  That means nothing to wear out & replace.
  • Electric motors burn out over time, and have to be replaced.  Not a problem with our products…if you supply them with clean air, they’ll run darn near indefinitely, maintenance free.
  • Using electric vacuums in wet areas can prevent a very real risk of electrocution.  This hazard does not apply to a compressed air hose, which is all it takes to run our products.
  • Long, stringy chips can get clogged in the impeller & rotating parts of a motor-driven vacuum.  Ours have no moving parts, which means nothing for detritus to get tangled up in.
Electric Vacuums are prone to clogging, wearing out, and motor failure.

Which EXAIR Industrial Housekeeping Product is right for you?  It depends on what you’ll be using it for.  Very generally speaking, here’s a brief overview of the product line:

Chip Vac Systems:

  • Pick up dry or wet chips and transfer them into a standard open top drum.
  • Available in four sizes: 5, 30, 55, or 110 gallon drums.
  • Turns your own 30, 55, or 110 gallon open top drum into a powerful vacuum system, in minutes, with a standard system.
  • Add portability and flexibility with a Deluxe System, which includes a drum dolly and a Tool Holder.
  • For a total Industrial Vacuum System, complete & ready to go right out of the box, the Premium Systems add a drum, a compressed air supply hose, an upgrade to Heavy Duty Aluminum Tools & a Static Resistant Vacuum Hose.
  • For smaller jobs or in tight quarters, the Mini Chip Vac System comes with a compact 5 gallon drum.  The Deluxe System adds a drum dolly for portability.

Heavy Duty Dry Vac Systems:

  • Function is similar to the Chip Vacs, but the vacuum itself is made of a hardened alloy, and offers higher vacuum power for dense and/or abrasive material cleanup.
  • Fits your existing 30, or 55 gallon drums for a quick & easy, basic high powered vacuum solution.
  • Deluxe Systems add Heavy Duty Tools & Tool Holder, and a Drum Dolly.
  • Premium Systems come with a 30, 55, or 110 Gallon Drum.

Heavy Duty HEPA Vac Systems:

  • All the power, durability, and convenience of the Heavy Duty Dry Vac Systems, but with a HEPA filter for contaminants such as mold, allergens, and other airborne irritants.
  • Fits your existing 30 or 55 gallon drums, or Deluxe & Premium Systems add the same accessories as the Heavy Duty Dry Vac Systems.

Reversible Drum Vac Systems:

  • These are our drum mounted vacuums for liquids.  They’ll fill or empty a 55 gallon drum in 90 seconds (tested with water.)
  • Fits an existing 30, 55, or 110 gallon closed top steel drum in good condition.
  • Deluxe Systems add a drum dolly, a Tool Holder and a set of plastic tools including a Spill Recovery Kit, for a multitude of cleanup needs.
  • Auto shutoff float prevents overfilling the drum.
  • Premium Systems add a 30, 55, or 110 gallon drum, Heavy Duty Aluminum Tools, and a compressed air supply hose.
  • High Lift Systems are available for higher viscosity (ups to 1400 cP) liquids, or when pumping from below grade (180″H2O suction lift.)
  • This same technology is incorporated into the Chip Trapper Systems, which (as detailed last week) trap incoming solids in a Filter Bag, allowing for instant pumping out of freshly filtered liquid.  They’re available with the High Lift capability as well.

Vac-u-Guns:

  • Handy and portable, the Vac-u-Gun is a lightweight handheld vacuum, blow gun, and transfer tool, all in one.
  • Collection System comes with a vacuum bag w/shoulder strap, extension wands, a crevice tool, skimmer tool, and round brush tool.
  • Transfer Systems come with the same tools, but include a 10ft hose instead of the vacuum bag.
  • All Purpose Systems come with the tools, the vacuum bag, and the 10ft hose.
  • Deep Hole Vac-u-Guns are fitted with a blow tube for stirring up fine debris from drilled holes, where it’s quickly and efficiently vacuumed away.

Regardless of your application, EXAIR has an Industrial Vacuum to fit.  Orders for qualifying systems through the end of May 2020 will include a free Vac-u-Gun.  If you’d like to discuss your Industrial Housekeeping needs, give me a call.

A Cold Winter’s Chill and Vortex Tubes

Two weekends ago I had the pleasure of flying out to meet my friend in Colorado Springs and ski the weekend at Breckenridge. As an avid skier Breckenridge has been one of the resorts I have been wanting to ski since I started skiing out west. The weather was amazing and I couldn’t ask for better; the Saturday blue skies and cool breeze followed up by a Sunday of snow fall. The Trip was a dream come true. Breckenridge is specifically known for having high winds that howl across the peaks that stand at a max of 12,998 ft. above sea level. These chilling winds would freeze just about anyone if you aren’t dressed prepared for them as they blow right in your face on the lift. As I was sitting on the lift with these cold winds blowing in my face it brought to mind EXAIR’s Vortex Tubes, Cold Guns, and Cabinet Coolers.

EXAIR’s Vortex Tubes and similar products provide everything from a cool blast of air to a frigid breeze to cool off various parts and products. In a lot of smaller milling and grinding applications the Cold Gun has been used as a replacement to costly coolant-based alternatives. Vortex tubes have been used in cooling applications since 1945 and assist in everything from stress testing electronics to cooling down plastic parts during ultrasonic welding.

 Vortex tubes use a source of compressed air to create a hot and cold stream of air coming out on opposite ends of the device. This means that not only can the vortex tube be used for cooling but also heating applications. In one case a vortex tube was used to heat up an adhesive before it was sealed to get a better adhesion. Although the vortex tube can be used for heating purposes those applications are few and far between as usually a heating element or other heating source is more applicable.
Vortex tubes are quickly adjustable, just as the winds of Breckenridge can change from being a breeze to almost blowing you off of the mountain. Weather in the mountains is always varying and so are EXAIR’s Vortex Tubes.

If you have any questions or want more information on how we use our vortex tubes to improve processes all over industry. Give us a call, we have a team of application engineers ready to answer your questions and recommend a solution for your applications.

EXAIR Chip Trappers Make Short Work of Coolant Maintenance

“Build a better mousetrap, and the world will beat a path to your door,” words attributed to Ralph Waldo Emerson, means that even if there are established methods of doing something, an improved method will garner success.  It may or may not be true with mousetraps – there are over 4,400 U.S. patents for various designs. The tried-and-true spring loaded bar on a small wood plank seems to still be the most popular by far, however. Likely due to its simplicity, availability, and low cost.

There are also a good many machines on the market to clean & filter machine tool coolant.  Some are made to be permanent attachments to the coolant sump for continuous filtration.  Others are made for portability, and are used to pump out the sump, filter the coolant, and pump it back in.  These can be impressively comprehensive, and that’s often reflected in the knowledge required to operate them, as well as the price tag.

Like anything else, if you need all the “bells and whistles,” I’m sure those machines are worthy every penny.  If you just want clean coolant and you have a few minutes to spare every week or so, look no further than the EXAIR Chip Trapper System.  Here’s how it works:

  • Roll the Chip Trapper to your machine.
  • Pump the coolant out of your sump, stirring it with the pickup wand to get chips & debris sucked up with the coolant.
  • Pump the filtered coolant back in to your sump.
  • If you’ve got another machine tool, roll the Chip Trapper over to it, and repeat.  If not, you’re done.  Unless the Filter Bag’s full, in which case, you’ll want to empty it for the next time.

The vacuum hose (1) is attached to the barbed connection of the Chip Trapper (2). The directional flow control valve on the top of the drum (3) and knob on the pump (4) are set to the “fill” position. The air supply valve is opened to permit compressed air at 80-100 psig (5.5-6.9 BAR) to flow through the pump which pulls the liquid through the hose, then into the reusable filter bag (5). When all liquid is in the drum, the air supply is turned off. The filtered liquid can then be pumped out by setting the directional flow control valve on top of the drum and the knob on the pump to the “empty” position. Once the air supply valve is opened, the air pushes the liquid back through the hose while all solids remain in the reusable filter bag.

There’s no moving parts, and it’s compressed air operated, so there’s nothing to wear out or burn out.  If you keep on top of emptying and cleaning the Filter Bag, the Chip Trapper will operate darn near indefinitely, maintenance free.  Oh, and to explain why I started this blog with the quote I referenced, the folks at Design News Magazine thought it was so innovative, they gave it their “Golden Mousetrap” Award when we rolled them out.  Since then, we’ve incorporated three sizes for 30, 55, and 110 gallon drums.  We also developed a High Lift version that generates 180″ H2O suction lift, for when the standard Chip Trapper‘s 96″ H2O lift isn’t enough.

EXAIR Corporation has a long history of making compressed air products that help a wide variety of industries get the most out of their processes, and the Chip Trapper is one of the most visible, and successful, examples of that.  If you’d like to find out more, give me a call.
