Upgrade Blowoff Applications with Engineered Products to Increase Safety and Efficiency

At EXAIR, it’s our business to make sure that you get the most out of your compressed air system.  We’ve got a Six Step plan to help you do just that, and one of those steps is the topic of today’s blog:

We have a couple of ways to help with step #1.  You can use a Digital Flowmeter to measure your total compressed air usage, and take advantage of our Efficiency Lab service to determine the consumption of individual compressed air devices that may be running up the total.  Based on our performance tests of those devices, we can recommend suitable EXAIR Intelligent Compressed Air Products to replace them with, along with the expected reductions in air consumption & noise levels…quieter is always better too.

We’re going to skip right over Step #2…just for now…but if you can’t wait, click on the picture above for more on finding & fixing leaks.

Once you get our recommended replacements in (I mean, why wouldn’t you?), they’re going to be part of your compressed air system, so naturally, we want to make sure you get the most out of them as well.  Key considerations are suitable supply lines, and proper installation.

In the case of a Super Air Nozzle or Air Jet, these are oftentimes one and the same.  They’re all small enough, and lightweight enough, to be adequately supported by compressed air piping (assuming the piping is adequately supported,) metal tubing (via a compression fitting adapter,) or even mounting solutions like our Stay Set Hoses.

Just a few ideas for installing an EXAIR Super Air Nozzle

Sometimes, though, you need a firm, vibration-resistant mounting…that’s where we recommend our Swivel Fittings.  A hex retainer tightly locks the ball in position, but allows for easy repositioning when loosened.  They come in standard NPT sizes from 1″ NPT down to 1/8″ NPT, and we even have them for the M4, M5, and M6 metric threads for our Atto, Pico, and Nano Super Air Nozzles.

Typical threaded fittings are limited in the angles you can achieve. EXAIR Swivel Fittings provide 50° of adjustability.

Even a highly efficient blow off needs to be aimed well in order to do its job well.  If you’d like to discuss how to get the most out of your compressed air system – or our products – give me a call.

The Case For EXAIR Swivel Fittings

One of the more common questions we get here in the Application Engineering department at EXAIR is…

“What’s the best angle to position a Super Air Nozzle?”

The simple (and perhaps a little snarky, but I swear that’s not intended) answer is…

“The angle it takes to get the results you need.”

But wait, there’s more…we’re not going to leave anybody hanging like that. Many blow off applications are going to be best served by a “sweep” of air, at a low angle. That will be ideal for removing a light layer of dust from a relatively flat and smooth surface. A bit larger angle, relative to the surface, may be necessary if you need some impingement force to dislodge sticky, clumpy, or mildly adhesive debris.  Rarely will you want to blow directly, at a perpendicular angle, to a material’s surface.  An exception to this might be if you’re trying to remove excess moisture from a porous and thin material, like a web fiber.

Regardless of what angle you need to aim your Super Air Nozzle, there are several ways to do it.  You can use a compression fitting them onto bendable copper tubing…just don’t bend it too much or too often.  We’ve got Stay Set Hoses that allow for quick & easy repositioning…they come in lengths from 6″ to 36″, and are in stock.

EXAIR Stay Set Hoses and Swivel Fittings are ideal for installation and positioning of your Super Air Nozzle.

If you want to hold it in place firmly and securely, you’re looking for a Swivel Fitting.  They’re available for almost all of our Super Air Nozzles, from the Atto to the 1″ NPT Model 1114 High Force Super Air Nozzle.  They offer 50° of total movement, and are made of Stainless Steel for durability in most any environment.

EXAIR Swivel Fittings have male NPT threads on one end, and female NPT on the other.  The smaller Swivels, for the Atto, Pico, and Nano Super Air Nozzles, have M4x0.5mm, M5x0.5mm, and M6x0.75mm female threads, respectively, in the ball of the swivel itself for direct threading of these small Super Air Nozzles.

EXAIR’s Swivel Fitting Family

Swivel Fittings can also be used with a host of other EXAIR products.  In addition to the Super Air Nozzles, for example, they’ve historically been very popular with our Air Amplifiers.  Here’s a short informational video showing just how versatile they are:

EXAIR Intelligent Compressed Air Products are made to be easy to install & operate.  This is our intent from Research & Development, to Shipping & Receiving.  If you have questions, give me a call.  I want you to get the most out of our products!

Improving Auger Cleaning Process Using 2″ Flat Super Air Nozzles And Swivels

I recently worked with a customer who was looking to improve the cleaning process on the  inside of one of their screw augers. They were currently using a couple of 1/4″ pipes as air wands to clean the left over powder on the auger blades and direct it toward a chute at the bottom which fed into another auger used for recovery. While the setup worked somewhat, they were concerned with the amount of air they were using as well as the OSHA safety concerns associated to using open ended pipes and excessive noise levels.

The customer was able to send a sketch of their current setup and after some further conversations, I recommended our Model # 1122 2″ Flat Super Air Nozzle and our Model # 9053 1/4″ NPT Swivel Fitting. The 2″ Flat Super Air Nozzle produces a 2″ wide, high velocity laminar airflow and uses only 21.8 SCFM (80 PSIG) while maintaining a low sound level of only 77 dBA. The Swivel Fitting allows for 50 degrees of movement, so they can achieve the best angle to direct the air to the critical areas.

2″ Flat Super Air Nozzle
Swivel Fittings available from M4 up to 1″ NPT

All of our Air Nozzles are engineered to meet or exceed OSHA Standard 1910.24(b) for 30 PSIG dead end pressure, they cannot be dead-ended, there is always a path for the air to safely exit so the outlet pressure will never reach 30 PSIG. In addition, our products are going to meet the OSHA Standard CFR 29 – 1910.95(a) for allowable noise exposure levels as well.

This Is A Hold Up

To clarify, right off the bat:

  1. Nobody is getting robbed here.
  2. Nothing is being delayed, especially a shipment from EXAIR. If it’s in the catalog, it ships on time, 99.97% of the time, for 17 years & running. This has nothing to do with this blog; I just never get tired of bragging about that.

Today I wanted to write about installing EXAIR products, but hey, it’s Friday, so I thought I’d start with something that would get your attention. If you’re still reading, I guess it worked.

We talk to users…and potential users…all the time about how to install an Air Knife, Air Nozzle, Vortex Tube, etc. And the answer is…it depends. But, it’s almost always quick and easy.

Consider the EXAIR Super Air Knife. There are a few ways to hold one in place:
*There are 1/4″-20 tapped holes, every 2″ along the bottom. These can be used to bolt it to just about anything you want to bolt it to.
*The 1/4″-20 cap screws can also be replaced with fasteners of sufficient length to allow use of a bracket. In fact, this is what we use for…
*The Universal Air Knife Mounting System – it’s a quick and convenient way to support an Air Knife. It’s especially beneficial to precisely position the Super Air Knife for optimum performance.
*Last but not least, Super Air Knives 24″ and longer need to be plumbed to both ends for proper performance. If you hard pipe it in, it’ll be as well supported as the piping.

EXAIR Super Air Knives are easy to install, no matter what the length, or application.

Then there’s our Super Air Nozzles:
*With standard, common NPT threads, these are easy to install anywhere you have an existing air line. You can get NPT adapters for darn near any threaded connection, off the shelf, from a friendly local air compressor or hydraulic/pneumatics shop.
*We’ve got Stay Set Hoses in lengths from 6″ to 36″ – these let you reposition the Air Nozzle at will. It’ll “stay set” until you bend it again.
*Our Swivel Fittings can be used with any of our Super Air Nozzles, as well as our Air Amplifiers, for sturdy, yet easily repositionable, installation.

EXAIR Swivel Fittings or Stay Set Hoses - no better way to optimize your air flow than aiming it where it needs to be!

How To Hold Up Just About Anything

My youngest asked me if we had any duct tape the other night. I got a swell of pride from the confirmation that I had indeed been successful in teaching him at least half of the basics of mechanical repair:

WD40 Duct Tape Flow Chart

However, he’s eleven, and I distinctly remember being an eleven year old boy, so I (prudently) asked what he wanted it for. He said he wanted to hang some posters in his room. Two things popped into my head:

1. I (or, even worse, his mother) would eventually be responsible for removing the duct tape, and
b. I know what duct tape can do when you try to remove it from drywall (again, from my experience as a former eleven year old boy),

I suggested that we use a more appropriate method, like Scotch tape. He was OK with that.

At EXAIR, we get questions from customers all the time about how to properly install/mount/support our products. Some are fairly straight-forward:

*Super Air Amplifiers (up to 4”) have an integral 2-bolt flange for secure mounting.

*Line Vacs (except Light Duty) are available with a rigid mounting bracket…these come with the Kit, or can be purchased separately.

*Cold Guns, Adjustable Spot Coolers, and Mini Coolers are supplied with magnetic bases for quick and easy mounting & positioning.

*We have a brand-new mounting bracket for our Atomizing Spray Nozzles…they have no fasteners; the Spray Nozzle simply “snaps” in, and out, as needed.

*The Ion Air Cannon comes with a sturdy stand for easy wall, bench, or machine mounting.

*Modular E-Vacs are block design, and have a series of mounting holes for convenient mounting.

*Even our Soft Grip Safety Air Guns have a built-in hook, for easy storage when not in use.

Many other products, like our Super Air Nozzles, Small/Medium Vortex Tubes, and our Adjustable Air Amplifiers (to name a few) are lightweight and compact enough to be secure when installed on properly supported compressed air piping. For added convenience, though, we offer value-added accessories such as Stay Set Hoses, Magnetic Bases, and Swivel Fittings as well.

Perhaps the most versatile product, as far as mounting is concerned, is the Super Air Knife. The 3” unit can actually be secured in place by properly supported piping, like the above mentioned lighter weight products. All Super Air Knives have ¼”-20 tapped holes, on 2” centers, along the entire length – these provide an easy way to mount to any nearby sturdy structure. If you’re mounting one over a conveyor belt, you can even support them by plumbing the compressed air with hard pipe to both ends. For quick, convenient, and easily re-positionable mounting, our Universal Air Knife Mounting Systems are just the thing.

These are just a few of the installation options available for some of our products. If you have questions or concerns about how to mount an EXAIR Intelligent Compressed Air Product, give us a call…we’re eager to help!
