The Case For The Flat Super Air Nozzles

What do you think of when someone says “air nozzle?” Is it a crimp or a “crush” on the end of a piece of tubing? Is it a device that attaches to the end of a pipe or a hose? If so, does it have engineered features that focus the stream, amplify the flow (through entrainment, perhaps,) reduce the noise level, or provide an element of safety?

If so…you’re right. Any of the above descriptions, strictly speaking, qualify as an “air nozzle,” in fact, just a plain open-ended pipe or tube meets the criteria. As long as it serves to discharge a stream of air towards a target, it’s an air nozzle.

Even the devices with those efficient, quiet, and safe engineered features come in a variety of styles, types, and models. Consider EXAIR’s product line of Air Nozzles and Jets…we have seventy-two distinct models, in a range of sizes, materials of construction, and performance.  That’s a LOT to choose from, and it doesn’t even take into account the products that can be fitted with different shims that, technically, make them a wholly different nozzle, performance-wise.  Which brings us, dear reader, to the focus of today’s blog: the Flat Super Air Nozzle.

Flat nozzles are not unique to EXAIR…there are dozens of others on the market in a variety of sizes and materials.  What IS unique about EXAIR’s Flat Super Air Nozzles is their performance…

Efficiency: When a competitor’s flat nozzle was replaced with a Model 1122 2″ Flat Super Air Nozzle, consumption was reduced from 31 SCFM to 21.8 SCFM.  Since the nozzle was operated 24/7, this resulted in a savings in compressed air cost of $3.31 per day…meaning the nozzle paid for itself in under three weeks.

EXAIR’s Flat Super Air Nozzles have been blowing away the competition since 2003.

Durability: Both our 1″ and 2″ Flat Super Air Nozzles are available in rugged Zinc Aluminum alloy, or heat & corrosion resistant Type 316 Stainless Steel.

Zinc aluminum models are perfect for general purpose blow offs (left,) while 316SS models are specified for food/pharma and high heat or corrosive environments (right.)

Versatility: A 0.015″ thick shim is installed in the Flat Super Air Nozzles.  These provide optimal performance in a wide variety of typical industrial and commercial blow off applications.  We also offer High Power versions, with a 0.025″ thick shim, for additional flow and force.  You can also experiment with other shims, from 0.005″ to 0.030″ in thickness, for customized applications.  These shims are all 316SS, and are available in sets, or individually.  The patented design of these shims, in fact, is key to their high efficiency, as explained in this video:

Ingenuity: While this EXAIR characteristic is not specific to the Flat Super Air Nozzles, our most recent ingenious development features them: the Super Air Scraper.  By combining a scraping blade with the 2″ Flat Super Air Nozzle, we’ve turned our very popular Soft Grip Safety Air Gun into the perfect tool for easy removal of sticky or stubborn debris from most any flat surface.

Scrape off, and blow away, stubborn debris with the Model 1244-48 Soft Grip Super Air Scraper.

EXAIR Flat Super Air Nozzles are Intelligent Compressed Air Products with a 15 year history of successfully solving all kinds of air blowing applications.  To find out more about how they can work for you, give me a call.

Accessories and the Value Added

The word “accessory” can come with some baggage… it’s become synonymous with “add-on” and “up-sell,” and cost-mindful consumers may see them as just another way for a slick salesperson to make an extra buck. And frankly, they wouldn’t have that reputation if there wasn’t some truth to it.  The server at your favorite restaurant will offer appetizers, or recommend side dishes to go with your entree. If you go to buy a new car, you’ll get a pitch for a variety of aftermarket add-ons.  The paint counter folks at the hardware store always tell me what specific brush and/or rollers I should use with the paint I’m buying…and it’s never the 10-pack of economy brushes that costs less than the single, premium quality brush they recommend.  In all of these cases, these employees are trained, constantly encouraged, and hopefully rewarded on the success of these “up-sell” strategies.

Of course, my boys and I can devour even the largest plate of chili cheese nachos long before the rest of meal comes out.  My wife absolutely loves the remote starter function that the dealership installed on the new car she bought last year.  And, if you’ve ever painted a well-lit room, you know the difference between a $1 paint brush and a $10 paint brush.  So if my server gets a little bigger tip, my car dealer salesperson gets a little more commission, or the paint counter folks get a bonus, then it’s a win-win, as far as I’m concerned.

EXAIR carries a variety of accessories for our Intelligent Compressed Air Products.  Some aid in mounting & installation:

Clockwise from top: Universal Air Knife Mounting System, Stay Set Hoses, Cabinet Cooler Side Mount Kit, Mounting Brackets for Line Vac, Filter Separator, and Pressure Regulator, Swivel Fitting for Super Air Nozzle, Tool Holder for Industrial Vacuum Drums, Spray Nozzle Mounting Clip.

Others make it easy to ensure adequate supply conditions:

The performance of many EXAIR Intelligent Compressed Air Products can be altered by replacing the shim:

From left to right: Super Air Amplifier, Super Air Knife, 1″ Flat Super Air Nozzle, High Velocity Air Jets, and Air Wipe all feature replaceable shims to modify performance.

In addition to these product-specific accessories, EXAIR carries a complete line of:

Filter Separators are rated for air flow up to 400 SCFM; Oil Removal Filters, up to 310 SCFM.

*Filter Separators to remove water, dirt, and rust from your compressed air system.  Our Automatic Drain Filter Separators have a 5 micron particulate element, and a centrifugal vane to remove moisture.

*Oil Removal Filters with coalescing elements that remove any trace of oil, and also provide additional particulate filtration to 0.03 microns.

 

*Pressure Regulators, so you can “dial in” the performance you need, so you don’t overpower the application, or waste compressed air.  They come in sizes from 1/4 NPT to 1-1/4 NPT, and are rated for flows up to 700 SCFM.  A pressure gauge provides accurate indication of outlet pressure, and the adjustment cap can be removed to prevent tampering.

*Mounting Brackets and Modular Coupling Kits for our Filters and Regulators.  The latter are especially handy for easy, compact, and leak free installation.

*Silencing Mufflers to reduce work area noise from compressed air exhausting from pneumatic cylinders, valves, etc.  There are several styles to choose from, depending on your needs:

  • Sintered Bronze Mufflers are simple in design, with minimal back pressure restriction, and come in sizes from #10-32 thread to 1-1/2 NPT.
  • Straight-Through Mufflers offer noise reduction up to 20 dB, and come in sizes from 1/4 NPT (up to 22 SCFM) to 3/4 NPT (up to 73 SCFM.)
  • Heavy Duty Mufflers have an internal stainless steel screen that not only protects the exhausting components from environmental contamination, but also keeps air system contaminants from being ejected at high speed into the work area.
  • Reclassifying Mufflers are an upgrade to the Sintered Bronze Mufflers and provide the highest level of noise reduction – up to 35 dB.  They also trap oil mist, eliminating breathing hazards to personnel.

*We have manual ball valves (1/4 NPT to 1-1/4 NPT) and Solenoid Valves (120VAC, 240VAC or 24VDC) from 1/4 NPT to 1 NPT, and a Foot Valve, for hands-free operation.

*Swivel Fittings to securely install & aim many of our nozzles, from the Atto to the High Force 1 NPT Super Air Nozzles.  For a little more flexibility, Stay Set Hoses and Magnetic Bases can be used for Air Amplifiers, Super Air Nozzles, and even short Air Knives.

*12 ft Coiled Hoses (1/4″ or 3/8″ ID) and Compressed Air Hose (3/8″ or 1/2″ ID; up to 50ft lengths) can be provided with any Intelligent Compressed Air Product.  We also have a full supply of fittings (tees, elbows, nipples, couplers, reducers, etc.) and adapters to fit our Super Air Nozzles to your existing air guns or blow off devices.

*Receiver Tanks are used to store a ready supply of compressed air.  If you have an intermittent demand of sufficient size, it can cause a pressure transient in your system, which can drag down the ability to supply other points of use.  Installed near the point of intermittent demand, they prevent pressure & volume fluctuations, keeping the operators at all points of use happy.  Model 9500-60 Receiver Tank has a capacity of 60 gallons, is rated to 200psig, and meets ASME pressure vessel code.

In closing, let me offer the following advice that’s served me well over the years:

*Be mindful of the valued added by the accessories & add-ons you’re presented during a purchase of capital equipment…or anything else, really.  Don’t buy something you don’t need, but if you need it…well…it’s OK to buy it.

*Don’t skimp on quality.  Odds are, if an accessory is offered by the manufacturer of the product, it’s going to work well for you.  They should be able to tell you if it will or won’t if you discuss your needs with them.  I know I will if you call me to discuss a compressed air product application.

*Get the big plate of nachos, especially if you’re dining with teenagers.

Where Has The VariBlast Compact Safety Air Gun Been All My Life?!?

Have you ever happened across something that would have been a real “game changer” at some time in the past? I’ll never forget the time that I went camping with my sons’ Boy Scout Troop, and I was introduced to the peanut butter and bacon sandwich. I still enjoy one from time to time, but my doctor does not enjoy hearing about it…

I’ve also written before (and before) about when I found out EXAIR Vortex Tubes were being used in some shipyards for freeze sealing pipes…a task that (when I worked in a shipyard) we used tanks of liquid nitrogen for.  I was amazed that such a cumbersome ordeal was replaced by something so simple and easy.

When we were developing the VariBlast Compact Safety Air Gun, a key feature…the variable flow trigger…also would have been real handy at a time in my not-so-distant past.  See, I used to run a small industrial equipment service department, and one time I found myself in a pinch to get a structural steel tube frame made for a support for a particular piece of equipment.  This wasn’t something we did all the time, and this particular job was a bit larger scale than most of what we’d done before.   It wasn’t really a big deal; I just had to cut some rectangular tubing to length with our band saw, drill some small holes (for bolts) and bore some larger holes (for cables & hose) along the length.

We had a small air compressor and a cheap commercial grade air gun, which served the purpose of our infrequent usage. Blowing the shavings away from those holes, and the inside of the tubing was a challenge…that air gun would just barely move them all the way from the holes near the middle, and when I blew out the holes near the ends, the spray of coolant-soaked shavings was making a heck of a mess in our relatively small shop.  After a while, I found that I could kind of “mash” the trigger a little to one side and get a rough measure of control…I was only going to have to mop about half the floor, instead of the whole thing, and I wasn’t going to have to wash the service truck parked in the closest garage bay to the shop area.

Needless to say, this wasn’t exactly ergonomic, and it was  real pain (literally) to use my left hand for a few days following.  Which, being left-handed, was kind of a drag.

Fast forward to just last year, when we rolled out the latest and greatest (in a distinguished line of latest and greatest) EXAIR product: the VariBlast Compact Safety Air Gun.  Now, individually, the key features might not be all that mind-blowing to the casual observer, but taken together, they’re a pretty big deal. Consider:

*Aluminum construction – lightweight, durable, corrosion resistant.

*Two compressed air inlets – one on the bottom (below your pinkie finger) and one on the rear (above your thumb;) your choice…whichever makes your task easier.

*Cast-in hanger – to keep it out of the way, but still handy, when you’re not using it.

*Chip Shield – you still have to wear safety glasses, but this will keep them cleaner.

*Wide selection of engineered nozzles – from our Atto Super Air Nozzle (2.5 SCFM; 2.0 oz force) to the 1″ High Power Flat Super Air Nozzle (17.5 SCFM; 16 oz force,) there are 20 distinct models in stock.  We can customize the performance of the VariBlast Compact Safety Air Gun to the specific needs of your intended use for it.

*Extensions – for applications that require a little (or a little more) reach, we offer the VariBlast Compact Safety Air Gun with rigid aluminum extensions up to 72″ in length.  These are particularly handy when used with the Atto Back Blow Nozzle.

*Variable pull trigger – as the name implies, you can “vary the blast” by how hard (or not) you pull the trigger.  Like I said before, you can do this – kind of – with a run of the mill commercial grade air gun, but it’s not very precise, and far from ergonomic.  Here’s a short video showing just how sensitive that trigger pull is:

If you’d like to give one a try, EXAIR offers these – and any catalog product for that matter  – with a 30 Day Unconditional Guarantee.  We invite you to put it through its paces for up to a month.  If it’s not going to work out for you, for any reason, we’ll arrange return for full credit.  Give me a call – we can talk about how you intend to use it, and which one’s right for you.

EXAIR Safety Air Gun Promotion

From August 1st to September 30th, 2018, EXAIR will be giving away a 1” Flat Super Air Nozzle with the purchase of any promotional VariBlast, Soft Grip, or Heavy Duty Safety Air Gun.  EXAIR is stressing the importance of safety in the workplace with the EXAIR Safety Air Guns as well as the versatility of the different types of EXAIR Super Air Nozzles.

SAGpromoAD_500xsq

This promotional item, the model 1126 1″ Flat Super Air Nozzle, has a patented shim to blow a 1” wide stream of air to clean surfaces quickly and efficiently and is a $45.00 USD value. For more details on the Promotion, click on the photo/link above. For more information about the Flat Super Air Nozzles, click HERE.

Inexpensive air guns can be purchased just about anywhere- online, via catalogs, and through industrial supply companies. Typical quality is less than ideal – broken triggers, leaky valves – a short lifespan in an industrial setting are merely a few of the issues observed.  Most are loud and inefficient – they just blow large amounts of compressed air, and at noise levels that violate OSHA requirements.  Some may even generate dangerous dead end pressure situations that that can result in serious or fatal injuries if blocked.

EXAIR’s Safety Air Guns have been engineered and designed to eliminate these issues. They are durable for use in industrial situations and comfortable to use for extended periods of time.  With an EXAIR engineered air nozzle, each model provides top performance by entraining large volumes of surrounding air into the air-stream. Operation is assured to be safe along with low compressed air consumption and noise levels.  Due to the design, the airflow that exits the nozzle cannot be blocked, as required by OSHA Standard 29 CPR 1910.242(b).

Safety Air Guns
The EXAIR VariBlast, Soft Grip and Heavy Duty Safety Air Guns

The VariBlast style of safety air gun offers variable force based on the range of trigger pull. Force can be varies, form a light breeze, to full force maximum output. This cast aluminum air gun can be fitted with any of the EXAIR 1/8 NPT engineered air nozzles.

The Soft Grip style of safety air gun  has a durable cats aluminum body suited for rugged, industrial use. The ergonomic design has a soft vinyl cover, a large trigger for easy operation, and a hanger hook for easy storage.

The Heavy Duty style of safety air gun is powerful with a durable aluminum cast body and ergonomic composite rubber grip, best suited for rugged industrial environments. Hours of fatigue free operation are possible.

With all of the Safety Air Guns styles, Chip Shields and Extension Pipes are available, from 6″ to 72″ in length.

Small, Precise Blowoff at Your Fingertips

For many blowoff applications, stronger isn’t necessarily better.  For applications and processes where a light, but effective blast of air is needed for cleaning and drying, the VariBlast Compact Safety Air Gun with the Atto, Pico, or Nano nozzle fits the bill. The smallest of the EXAIR engineered Super Air Nozzle family, the Atto, Pico, and Nano have been designed to provide the smallest, most precise blowoff possible. The focused airflow pattern allows for very accurate control and placement of the air stream.  The nozzles are available in both Type 316 Stainless Steel and PEEK plastic (useful for harsh environments, and is non-marring)

img_7480.jpg
The Atto, Pico, and Nano Super Air Nozzles (Scale is in Inches)

The new VariBlast Compact Safety Air Gun is a great choice for putting the power and performance of the nozzle into a small and lightweight air gun. Designed with a variable flow trigger, the airflow can be throttled from a whisper to full force, simply by varying the trigger pull distance.

1698SS
VariBlast Model 1698SS, with Stainless Steel Nano Super Air Nozzle

The Atto, Pico, and Nano nozzles use very little compressed air and are extremely quiet, easily meeting OSHA Standard 29 CFR 1910.95(a) for Noise Exposure.  The design incorporates engineered solutions for safety and can be supplied with higher pressure compressed air and meet OSHA Standard 29 CFR 1910.242(b), relating to dead end pressure requirements.

The table below provides performance data, including the compressed air consumption, force, and sound level for the various configurations.

EXAIR Flat Super Air Nozzles – Adjustable, Flexible and Powerful

As an Application Engineer here at EXAIR, we get calls from customers looking for an air knife, but shorter than our typical 3″ stocked size.  We can make an air knife to any length needed, but we will look at the 1″ and 2″ Flat Super Air Nozzles as a possible solution.

Like an air knife, the Flat Nozzles provide a wedge shaped pattern of air that maintains the width of the nozzle, to create a concentrated, powerful air flow.  Thus, a 1″ Flat Super Air Nozzle has air stream 1″ wide, and the 2″ Flat Super Air Nozzle has one 2″ wide.

The Flat Super Air Nozzles are available in zinc aluminum alloy or type 316 stainless steel construction, to meet environmental conditions of the process.  Both the 1″ and 2″ nozzles contain a changeable, patented shim that maintains the critical air gap, which allows the release of a precise amount of air through the thin slot, across a flat surface. The result is a wide, forceful stream of high velocity, laminar airflow, with minimal air consumption and noise.

1″ and 2″ Flat Nozzles, in Zinc aluminum Alloy and Type 316 Stainless Steel

Shims are available in thicknesses of 0.005″, 0.010″, 0.015″, 0.020″, 0.025″, and 0.030″.  Shim Sets with either 2 or 3 shims are available for both sizes to allow for adjustment of the performance to best meet the application need.
