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.

Safety Air Guns: Chip Shields, Extensions, and More

Over the last several weeks, you may have read blog posts regarding the EXAIR Safety Air Guns.  You can find the blogs here, here and here. We are also in the midst of a Safety Air Gun Promotion, please click HERE for more details on how you can get a free 1″ Flat Super Air Nozzle. Today, I want to review a few available options for the Safety Air Guns.

Protect Workers From Flying Debris! – Chip Shields are durable polycarbonate shields that protect the operator from flying debris often seen when blowing off chips from machined parts. They are also useful to prevent coolant from splashing back, creating a mess during drying processes.

Chip Shields

The Chip Shields are available for EXAIR’s VariBlast, Soft Grip, and Heavy Duty Safety Air Guns. The Chip Shield can be used on Safety Air Guns with or without an aluminum extension. They may be purchased as part of a new air gun system, or retrofitted as a Chip Shield Kit.  Consult an Application Engineer for selection assistance.

 

If you have a blow-off process where the air is to be directed at a distance away from the operator, or into a hard to reach location an extension is the solution. Available in lengths from 6″ (152mm) to 72″ (1829mm), with sizes as shown below, a length to meet most any requirement can be found. To add an extension to an air gun, simply add -xx to the current part number.

Powerful and Safe Blowoffs with EXAIR’s Heavy Duty Safety Air Gun

EXAIR’s Heavy Duty Safety Air Gun is designed to provide powerful blasts of compressed air for use in rugged, industrial environments. With a larger 3/8 NPT air inlet compared to our other Safety Air Guns, it allows for higher force and flow values. It comes with a durable cast aluminum body and ergonomic composite rubber grip. The wide curved trigger allows for continuous use for hours without operator’s experiencing fatigue.

HP1330SS-6-CS
Model 1330SS-6-CS

All of EXAIR’s Safety Air Guns come with an engineered compressed air nozzle at the tip. This allows you to remain OSHA compliant while still getting the force you need to get the job done. EXAIR’s Super Air Nozzles utilize the coanda effect to entrain large amounts of ambient air from the environment. This ambient air mixes with the primary airstream and is projected towards the target with more force and flow than the supplied compressed air could deliver alone.

Each of the Safety Air Guns is available with extensions fully assembled ranging from 6”-72”. You can simply add a “-“ and the required length, in inches, to the end of any Safety Air Gun Model number.

In addition, they’re also available with a Chip Shield to prevent any chips or debris from coming back into the faces of your operators. Effective chip guarding is another component of OSHA 1910.242(b) in addition to the concerns of dead-end pressure. To add a Chip Shield onto the gun as well, a “-CS” to the standard Model number. For example, a Model 1310-12-CS would be a 1310 gun with 12” extension and a Chip Shield installed. If the application involves blowing off metal chips or shavings, your operators will certainly appreciate this Chip Shield preventing the debris from blowing back all over them.

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.

Safety Air Guns – Using Engineered Air Nozzles For High Performance

Inexpensive air guns can be picked up just about anywhere, and you generally get what you pay for. Most will be very noisy and waste lots of compressed air.  And many will be unsafe, violating two of OSHA’s standards put in place to protect worker safety. The first is Standard 29 CFR 1910.95(a) which sets limits to the maximum noise exposure, and the second is Standard 29 CFR 1910.242(b) which says that the nozzle cannot be dead-ended, or exceed a 30 PSIG pressure limit.

These guns may seem like a perfect fit for a handheld blowoff application. The truth is, the cost saved up front will easily be paid throughout the cost of ownership.  This is due to the lack of an engineered nozzle which meets and exceeds the OSHA standards mentioned above.   The “cheap” guns often have a cross drilled hole to meet or exceed the OSHA standard for dead-end pressure. While this may be true, it causes a large wind sheer which escalates noise levels to well over the allowable noise level exposure set by OSHA.  These tips sometimes offer large force outputs because they are equivalent to an open pipe.  We have publicized numerous times about how an open pipe blow off does not permit pressure to be utilized all the way to the point of blowoff, and is also a waste of energy.

In order to determine how much compressed air your current blow guns utilize, the level of noise they product, and the sound level they produce, consider taking advantage of the EXAIR Efficiency Lab.  The Efficiency Lab is a free service that you can read more about here.

An EXAIR Safety Air Gun is engineered and designed to comply both of the OSHA standards mentioned above, ensuring safe operation for company personnel.  On top of the safety designed into the guns, we also ensure all of our guns are efficient by offering only engineered nozzles on them.

EXAIR offers (4) types of Safety Air Guns – the VariBlast, the Soft Grip, the Heavy Duty, and the Super Blast.  Each type of Safety Air Gun is offered with a plethora of nozzles, as well as varying length extensions, with or without the Chip Shield.
