EXAIR’s High Velocity and Adjustable Air Jets – Now Available in Stainless Steel

Newly released, the EXAIR High Velocity Air Jet and Adjustable Air Jet are now available in Type 303 Stainless Steel, providing greater durability, corrosion resistance and a higher maximum temperature rating of 400 °F.  Type 303 stainless steel has good resistance to mildly corrosive atmospheres along with good oxidation resistance at elevated temperatures, making the stainless steel Air Jet a great choice for blowoff or part drying in your harsh environment. Both types of Air Jets are also available in brass, for applications at 275°F and below, and when corrosion resistance is not as critical.

Model 6013SS – High Velocity Air Jet

Air Jets utilize the Coanda Effect – wall attachment of a high velocity fluid – to produce air motion in their surroundings. As illustrated above, a small amount of compressed air to the inlet (large black arrow) is throttled through an internal ring nozzle above sonic velocity.  A vacuum is produced, resulting in large volumes of surrounding, or “free” air, being pulled in through the jet (blue arrows.)

Both the outlet and inlet can be ducted for remote positioning applications.

If the end is blocked, flow simply reverses at well below OSHA dead end pressure requirements, ensuring safe operation.

The High Velocity Air Jet comes standard with an .015″ shim, and a Shim Set is offered that includes .006″ and  .009″ shims to provide additional adjustability and control.  The Adjustable Air Jet has a variable gap design, and can be adjusted and locked to meet the required airflow and thrust parameters.

When you are needing a simple solution to reduce excessive air consumption and noise levels on compressed air blowoff operations, EXAIR has a large line of Air Nozzles and Jets to solve your problems. You can contact an Application Engineer to discuss which Air Jet or Nozzle to best fit your application.

Practice Makes Perfect

2016 Eagles

NEW Eagles Football Jersey for 2016

Last year, I wrote a few blogs about how I was an assistant coach for my oldest son’s youth football team. We had an amazing season that ended with a 2nd round playoff loss and a 3rd place finish overall. Not too shabby for a new group of players and coaches. Now, the new season is upon us with practice beginning next Monday. Our new roster is pretty much the opposite of last season, as we now have 11 returning players from last year’s team and 4 newcomers. The coaching staff has stayed intact as well, so we are hoping to improve on last year’s successes and bring home the championship this year! But hey, we are talking about 7 and 8 year old boys here, so ANY type of success is a win in itself.

After a brief coaches meeting over the weekend, we have decided to hold practice 3 days a week this year, compared to 2 days last. We are hoping the extra practice will help us implement some more pass plays in the offense and work on extending our defensive sets, which cost us at the end of last year. For me personally, I am excited to see how my own son has grown from his first season of learning how to block and tackle the right way, to being more involved in the offense. He is one of the fastest kids on the team but got a little nervous whenever we tried to get him the ball on a rush or pass play. He and I have spent A LOT of time this spring and early summer, throwing the ball and working on his ball carrying skills. From what I’ve seen in our yard, I am pretty excited to see what unfolds on the football field. I keep telling him that he’s going to have some dropped passes and fumbled balls, but the important thing is to not get discouraged and keep trying. After all, practice makes perfect.

Here at EXAIR, we adopt the same philosophy. We are dedicated to putting in the time and effort to develop new and useful compressed air operated products. The following is a list of some new products now available:

  • New 2.5″ and 3″ Line Vac and Threaded Line Vac in 316SS and High Temperature construction

    Standard Line Vac: aluminum or SS

    Standard Line Vac in aluminum or stainless steel

  • New 2.5″ and 3″ Heavy Duty Line Vac with smooth or threaded ends. Hardened Alloy Construction for better abrasion resistance.

    Heavy Duty Line Vac: Hardened Alloy Construction and High Performance

Multiple Choice

My oldest son got his driver’s license last week.  There was a popular commercial for an insurance company, a while back, that touted how “life comes at you fast,” and that’s been the story of my week:

Friday: Son passes driver’s exam, first time, 100%. Proud Dad moment.
Saturday: Dad & Son go used car shopping. Pride has a price tag.
Sunday: Dad & Son bond while detailing new (to us) car. Son learns what to do when engine in 10 year old car stalls while backing out of driveway cold. Pride usually is followed by lesson in humility.
Monday: Mom adds Son to auto insurance policy. Insurance agent no longer concerned about funding retirement. Pride is getting expensive.
Monday part 2: Son learns valuable lesson about leaving lights on when parking at school in pre-dawn hours. Dad’s portable jumpstarter finds new home in trunk of Son’s car. Lessons in humility have caused pride to approach pre-licensing levels.
Tuesday-present: Enjoying what we can of a return to incident-free normalcy (and I hope I didn’t just jinx it by putting that in writing.)

We had quite a few choices, looking at cars in our (limited) budget range. Having these choices allowed us to choose the features that most appealed to us. They were pretty much all small-to-mid-size used cars with automatic transmissions and fuel efficient (read: small) engines. The one we settled on was the same model (and a year newer) as one I’d owned previously. It was one that had proved reliable, and safe…I was in an accident in that one where the air bag deployed, and I walked away with no injuries. Safety is a big selling point for me, especially where my family is involved.

When we speak with customers at EXAIR, many times, we too, can offer multiple choices to provide a solution.

I had the pleasure of helping a caller with a chip removal application recently. The application was to solve a problem with stringy chips wrapping around a plastic cylindrical part as it was turned on a lathe. The initial thought was to use a Super Air Nozzle to blow them away. Our Model 1100 1/4 NPT Zinc Aluminum Super Air Nozzle was discussed…inexpensive, low air consumption, easy to mount (we also talked about Stay Set Hoses and Magnetic Bases,) and super quiet.

EXAIR Model 1100 Super Air Nozzle is commonly used in point-of-cutting debris removal applications.

EXAIR Model 1100 Super Air Nozzle is commonly used in point-of-cutting debris removal applications.

The second thought was to use a small Line Vac to convey the debris away. Small footprint, easy to install, collection of waste in a receptacle away from the machine, still easy on air use & noise level.

Model 6080 3/4" Line Vac is also used in point-of-machining applications, removing debris from the site altogether.

Model 6080 3/4″ Line Vac is also used in point-of-machining applications, removing debris from the site altogether.

The third option came up when discussing tool life. Turns out, one of their machinists was familiar with our Cold Guns, and how they had been used to markedly improve tool life while eliminating the need for coolant at a previous job. This turned out to be all it took for them to try the Model 5215 Cold Gun Aircoolant System.

EXAIR's Cold Guns not only blow debris away, but also provide cooling for tool life improvement.

EXAIR’s Cold Guns not only blow debris away, but also provide cooling for tool life improvement.  With (4) Models to choose from, we’ve got the right one for your needs.

Any of the three options – Super Air Nozzle, Line Vac, or Cold Gun – should have solved this application successfully, with different benefits. They simply chose the one with the benefits that appealed to them the most.

If you have an application regarding compressed air product use that you’d like to discuss, give me a call. We’ll cover all the bases, and get the one that works best for you.

Where Did All The C Clamps Go?

Over the past week I visited a local company here in Cincinnati that utilized a decent number of flat plastic air nozzles on their production lines.   This style nozzle had been used for many years but were the reason their engineering department contacted EXAIR.   The nozzles they had in place were used in many different applications from ejecting bad parts, holding up box flaps, and even positioning product correctly on the production line.   Every nozzle was tied to a regulator somewhere on the machine and all of the regulators were tuned to different pressures.

The customer was experiencing, at certain points during the day, a pressure drop throughout the entire system that would cause packaging lines to shut down due to low air pressure faults. The customer called EXAIR because they determined the plastic nozzles were using too much compressed air and were also a constant maintenance problem. Primarily, they wanted to see if we had a solution to lower compressed air while still achieving the desired production results.

Being local we were able to visit the customer and after discussing the applications we set out through the manufacturing area to discover if we could offer solutions for the problematic areas. We got about 10′ away from a casing machine and I heard a loud hiss of compressed air.   This was even with my foam ear plugs in.  Once we reached the edge of the machine I was quickly able to trace the sound down to a plastic flat nozzle that had been mounted to the machine, broken and held back in place by a large C clamp like seen below.

As we went through the rest of this production line and the rest of the packaging facility, it was clear the customer had settled on using flat plastic nozzles throughout the plant. Generally we see this because the nozzles are cheap – when you forget to consider operating and maintenance costs. This was not the only broken nozzle being held in place by a clamp and it is also the not the only one that was using more compressed air than necessary.

After finishing the tour and performing some tests here in our lab I recommended that they utilize our 1″ Flat Super Air Nozzle with a .005″ thick shim installed.   By installing the 1″ Flat Super Air Nozzle they are going to be able to mount the metal nozzles with minimal modification to their existing setup as well as lower air consumption and noise level. The metal construction makes them more durable and long lasting in an industrial environment. These nozzles will not break when an operator bumps it and the maintenance department will be able to reclaim all the C clamps that are distributed throughout the facility.

Once we have final numbers on how many nozzles have been replaced and what pressures each nozzle is operated at we will provide the customer the air consumption savings as well as the noise level reduction that they are seeing throughout the plant.

Keeping the Confusion Out of NPT Pipe Thread Dimensions

I recently had the pleasure of helping a caller solve a problem with a Super Air Nozzle.  He had measured the opening on the outlet of his air gun, and ordered accordingly…unfortunately, he didn’t know that 3/8 NPT did NOT correspond to a 3/8″ diameter of a threaded fitting.  I explained the reason for this, a while back, in a blog entitled “When Is A Half Inch Not A Half Inch? When It’s Half Inch Pipe, Of Course!

The ID of a 1/8 NPT threaded fitting is actually pretty close to 3/8". Here's a dimensions table that I reference often.

The ID of a 1/8 NPT threaded fitting is actually pretty close to 3/8″ (left.) Here’s a link to a dimensions table that I reference often to keep this (on right, a 3/8 NPT nozzle with an 1/8 NPT air gun) from happening.

 

As you can see, the Model 1105 3/8 NPT Super Air Nozzle will not fit the 0.405″ (not far at all from 3/8″ if measured with a ruler) ID of a 1/8 NPT threaded connection.  No matter; these are all catalog parts that we have plenty of stock on, so, after a brief discussion of pipe thread sizes, he got a Model 1103 1/8 NPT Super Air Nozzle, and it fits just fine:

IMG_5789

Sometimes, an adapter is required for air guns that have straight threads.  Two common sizes for these are 5/8″-28 and 3/4″-32 – and we have adapters for both of these (call for details.) Other adapters are readily commercially available…you may find them in the plumbing aisle of your hardware store, or from a local pipe & pipe fitting supplier.  We’ve seen some air guns, though, that have a proprietary thread that doesn’t match up to anything else…in these cases, we have four types of Safety Air Guns on the shelf, ready to ship.

If you’d like to find out more about using quiet and efficient engineered Super Air Nozzles for your air gun applications, give me a call.

The Only Constant Around Here Is Growth

But if there’s a second constant around here, it’s excellence. And if there was a third, it was this guy…right up until the day he retired:

Joe Panfalone, Application Engineer extraordinaire, holding our bounty of product awards from 2013. He's retired since, but he's not...EVER...forgotten.

Joe Panfalone, Application Engineer extraordinaire, holding our bounty of product awards from 2013. He’s retired since, but he’s not…EVER…forgotten.

Another thing we don’t want to forget – in fact, I’m writing this as a reminder to YOU, dear reader, is that EXAIR products are up for ANOTHER four Plant Engineering Product of the Year Awards this year.  If you haven’t familiarized yourself with this year’s entries yet, there are some VERY cool products to choose from, and I highly encourage you to check them out(Disclaimer: I was an engineer BEFORE I came to EXAIR, and as such, I fully recognize the value that our esteemed colleagues bring to the table with THEIR entries, but I remain convinced that OURS are the clear winners here, as I’m sure you will too.)

Voting ends this Friday, January 8th 2016, so please hurry.  We’re honored to have gotten the nod in four categories this year:

ETC Dual CC SystemsAutomation and Controls: The competition is pretty stiff in this category…I’m sure you’ll recognize the names of some major players.  But, considering the wide range of applications, the potential cost savings by regulating the use of compressed air, and the convenience afforded by the ETC Dual Cabinet Cooler Systems, it’s a real contender.

HLRDVEnvironmental Health: With the ability to vacuum heavier tramp oils, thicker sludge, more viscous fluids, and “in the floor” cisterns, the High Lift Reversible Drum Vac makes fluid transfer and spill cleanup quick & easy.  They’re in stock for 30, 55, or 110 gallon drums. If you want a drum dolly, additional vacuum tools, or even the drum itself, check out our Deluxe and Premium Kits.  With all due respect to the other entries, it’s the clear winner in this category.

Compressed Air1006ss: This has been a long-awaited addition to our already broad selection of engineered air nozzles: the Back Blow Air Nozzles, available in two sizes, can handle blowing out pipe, tube, etc. with inside diameters from 7/8″ to 16″.  You can get one installed on one of our Safety Air Guns, and they’re available with Chip Shields, and extension pipes up to 6 feet in length.  This is the most innovative product being introduced in this category this year, for sure.

Fluid HandlingNo Drip Atomizing Nozzle: The patented design of the EXAIR No-Drip Atomizing Spray Nozzle offers a stand-alone nozzle capable of controlling liquid flow without requiring a liquid control solenoid.  When the air supply pressure is shut off, so is the liquid flow…just like that.

This feature is available on any of our Atomizing Spray Nozzles.  For safety, efficiency, cleanliness, it can’t be beat.

Remember, voting ends this Friday.  I know there are some great products to choose from, but all of us at EXAIR would genuinely appreciate your vote for our products.  Of course, if you ever have any questions about how these – or any of our Intelligent Compressed Air Products – can make life easier, give me a call.
