Super Air Nozzles for the Blowoff, and the Win!

Just take a moment and really look at the precision that is engineered into these SUPER Air Nozzles. The fins, the angle of the holes. The only thing missing is a cape and an S on the front like this one on the right. At a quick glance, these nozzles look simple, but they are far from it. I’ve had multiple customers reach out because they are using a simple open pipe to blow off X, Y, or Z. It really is mind “blowing” to me to hear this. Just a few days ago, I spoke to a customer that has over 20, 3/8″ open lines that blow air 24/7. I can almost hear that problem from here, and I definitely can feel the pain of their money being waisted. Up to 80% of your air can be saved with the right nozzles vs. open pipe or tubes. If waisitng money isn’t enough, the noise alone would be deafening without the nozzles, and not at all up to OSHA standards.

These Super Air Nozzles comply with the OSHA standards 29 CFR 1910.242(b) for dead end pressure requirements, and 29 CFR-1910.95(a) concerning noise. The only exceptions to the noise level is when we get into our High Force nozzles. As you can imagine, if you are needing more than 90 SCFM of air, with 4.5+ pounds of force out of a nozzle, it will make some noise. By the way, it will still meet OSHA’s dead end pressure standard and the EXAIR defines how much unprotected noise exposure is allowed by OSHA with each nozzle above their threshold.

When we look at the fins and shapes of the holes, they are intelligently designed to maximize the coanda effect on each nozzle. This allows these nozzles to amplify the compressed airflow (black Arrow) up to 25 times or more. As the air travels along the outer wall of the nozzles it will entrain the surrounding air into the airstream. This results in a high velocity blast of air with minimal consumption.

If you have any type of homemade or makeshift blowoff system using copper tube, open pipe, or pipe fittings please take a moment and look at the amount of air that is being waisted. We can use these Super Air Nozzles to save an astronomical amount of air. Take a look at this Air Consuption table as a solid example:

As you can see on this table the 1/4″ Copper Tube uses 33 SCFM, and the 1/4″ Open Pipe uses 140 SCFM. Now when we install the 1/4″ Super Air Nozzle it drops the cunsumption down to 14 SCFM. The benefits do not stop there. The noise is dropped to 74 dBA, and you are no longer violating the OSHA requirements.

When you have a blowoff situation, please reach out and discuss our options. Many times the solution is as easy as using a Super Air Nozzle and sometimes you may actually need the Flux Capacitor. We are here to help guide you between these two extremes. Please feel free to reach out at anytime to discuss your Air Nozzle, or any other compressed air solutions.

Blow Off Systems for the “W”

Many times we have tendencies to overcomplicate things. I remember a time when I was visiting my sister in Phoenix, and she was making a fancy 3D Scooby-Doo cake for my nephew’s 4th or 5th, and she needed the brown icing. Now when decorating these cakes, the common practice is to make white icing and use food coloring to make all of the other colors you need. She left that morning around 10:00 to look for brown food coloring. Around noon she called to tell us that she could not find brown food coloring at any store on this side of town, and was driving to the far side of the city to look at those stores. I asked her why she couldn’t just use chocolate icing, and she was having no part of it. She was so laser focused on her solution that she couldn’t hear that that chocolate icing is also brown… Fast forward to 6:30 PM, and she comes walking through the door frustrated and exhausted from her day of going store to store all over the large city looking for the elusive brown food coloring. As you can probably guess, she had chocolate icing with her because it finally hit her that the chocolate icing is brown… . The cake turned out amazing, and the lesson was learned.

So, why this story? I feel that in life and in business we sometimes leave our blinders on and become laser focused on one certain way of doing something. We know that the way we se it will work, and think that we know best, and we are going to make it happen exactly how it is playing out in our head. No other way seems possible, and when someone offers up a simpler solution, our immediate thought is “it can’t be that simple”, or “if it’s that simple of a solution, there is no way it could work”. Have you ever said these things? As an application engineer, I take a lot of calls from people that are much smarter than me with grandiose plans. Many times the problem they need to solve, is much simpler than the solution they have in mind. I’ve seen elaborate plans, that probably took hours if not days to develop, come down to simply needing a simple out of the box Blow-Off System.

At EXAIR, we specialize in intelligent compressed air products with a primary focus on blow off, drying, and cooling. When it comes to these things, our product lines (pointedly for this blog, our Air Nozzles and Jets) are head and shoulders above our competition. The vast majority (with the exceptions of the High power or high force nozzles – for obvious reasons) all meet both OSHA standards concerning noise and dead end pressure. Here is a list of all of our Super Air Nozzles showing the SCFM, Force and Decibels:

Our Blow Off Systems (some sample pics below) are a fantastic and smart solution for so many applications. It really doesn’t get much easier than this, a Magnetic base, a Stay-Set Hose, and a Super Air Nozzle, all in one. I feel that these are heavily under utilized. Simply connect your air hose, bend the Stay-Set Hose to the direction of spray that you need, and boom, Bob’s your uncle…

Mag Bases come with one or two outlets. Stay Set Hoses come in lengths from 6″ to 36″.

Sometimes things can be as simple as using chocolate icing for brown icing, or using an EXAIR Blow-Off System in your application. Of course if you need more than that, we will help you find the right solution for you. Call today to speak with an experienced application engineer that is eager to help.

EXAIR Blowoff Systems For Easy Air Nozzle Installation and Aiming

EXAIR engineered Air Nozzles are quiet, efficient, and safe, which makes them ideal solutions for air blowing applications. Selection is largely determined by the size & shape of the desired air flow. Our Air Nozzles & Jets catalog section lists them all, from smallest to largest, along with performance data and airflow patterns, so determining the right one for your application is pretty easy.

The next question is, how do you install it? If it’s replacing another blowing device, odds are, you’re an adapter fitting away (if that) from a quick & easy install:

Compression fittings and Model 1100 Super Air Nozzles transformed the part ejection on this press from “loud and wasteful” to “quiet and efficient” in about a minute.
Swivel Fittings for Air Nozzles.

For new installations, your compressed air drop may be located some distance from the installation. Properly sized pipe or hose can get you from the drop to the point of installation, but what happens when you get there? If you use hard pipe, and you can run it right to the spot where you want the air to blow, your Air Nozzle will essentially be as well supported as the piping. A Swivel Fitting will then allow you to aim it precisely.

Compressed air hose is inexpensive and easy to work with, but it provides no support for a blow off device at the point of use. This is where EXAIR Blowoff Systems come in. Any EXAIR Air Nozzle, up to our 1/4 NPT models, can be fitted with a Stay Set Hose which, all by itself, could be used at the end of a properly supported piping run instead of a Swivel Fitting. It’ll give you more reach – they come in lengths from 6″ to 36″ – and more flexibility in adjustment than the Swivel Fittings.

Precise aiming and location is a breeze with EXAIR Stay Set Hoses.

If you don’t have a pipe manifold like the one shown above, but you have an iron or steel surface in close proximity, a Magnetic Base can be used. EXAIR offers three styles:

Model 9042 Single Outlet Mag Base (left), 9043 Dual Outlet Mag Base (center) and 9029 Swivel Mag Base (right), and some typical uses.

If you’re looking for an efficient, quiet, and safe method of blowing compressed air, EXAIR has you covered with a wide variety of Intelligent Compressed Air Products to choose from. If you have questions about them, or how to mount them for optimal performance, give me a call.
