Following is one example for a customer who purchases air guns.
Several months ago I received a call from a company that was looking for a specialized air gun. This company was involved in the servicing of highly specialized measuring equipment and needed a safe, quiet, & efficient air gun that also had to be completely oil/contamination free. This was to ensure no contamination would result from using the air gun on any of their equipment. Ultimately this meant that every air gun component needed to be washed, rinsed and dried to ensure there was no residual oils or dirt from manufacturing left on or in any component of the gun.
Our customer decided on the highly versatile Vari-Blast Compact Safety Air Gun with the award-winning Nano Super Air Nozzle, specifically models 1698SS and the 1698SS-6. EXAIR presented a written process to the customer. This process explained how we would identify and manufacture their specific air gun in order to assure the customer that would receive a consistently clean air gun, every time.
Additionally the customer had specifications requiring special packaging as they were going to ship these globally to their service team members. To ensure safe arrival no matter where they are shipped, EXAIR provides special handling and packaging which exceeds their requirements.
Also, when you are looking for expert advice on safe, quiet and efficient point of use compressed air products give us a call. We would enjoy hearing from you!
A metal fabricator used a cutting machine to cut different sizes and shapes of stainless steel tubing. The process was automated and the machine would cut two tubes at a time. After the cutting operation, the machine would deposit the tubes into a nearby bin. The operator would then stack the tubes in a wooden container as shown above. Before the tubes could be transported to another department, the operator would have to clean the inside of each tube. The current method was to attach a rag to the end of a rod and pushed it inside the tube to remove any coolant and chips that remained from the cutting operation. Of course, the ability to clean thoroughly with a rag is reduced greatly after a short time of use. The cleaning process was very time consuming, and when the rag was not changed in a timely manner it did not clean effectively. The inside of the tubes would get marred from the excess chips that remained on the rag. This would visually affect the surface finish of the stainless steel. They emailed me the application detail as they were looking for a non-contact way to clean the inside of the tubes.
The first question from the customer was if we could customize our air nozzles to clean the different diameters and shapes that they were cutting. EXAIR has made special air nozzles to accommodate unique applications, but I wanted to first make sure that EXAIR did not have a manufactured nozzle in stock to fit this application. I requested the dimensional information, and the customer sent me the sizes and shapes of the tubes that were ran through their cutting machine. (Reference Table 1 below).
EXAIR manufactures three different sizes of Back Blow Air Nozzles that are designed to clean inside tubing, pipes, hoses, and channels. They can range from internal diameters from ¼” (6.3mm) to 16” (406mm). The 360o rear airflow pattern can “wipe” the entire internal surface clean and can remove coolant, chips, and debris. In reviewing the dimensions from Table 1 above, I was able to recommend just one Back Blow Air Nozzle for all the tubes; even the square and rectangular ones. It was model 1006SS Back Blow Air Nozzle. This 316SS robust designed nozzle can fit inside and clean tubes with internal dimensions ranging from 22mm to 102mm, and it was perfect for all of these tubes.
The customer indicated to me that the tubes were all cut to identical lengths at 550 mm (21.7”). Being that this was a manual operation, I suggested the Back Blow Air Nozzle with our Soft Grip Safety Air Gun. This ergonomically designed Safety Air Gun is designed for hours of use without fatigue. In combination with the nozzle, we are able to add extensions and chip shields. With extensions, EXAIR has a range of lengths from 6” (152mm) to 72” (1,829mm). With the designated length above, I recommended the model 1206SS-24-CS which has the Soft Grip Safety Air Gun, the model 1006SS Back Blow Air Nozzle, a 24” (610mm) extension, and a chip shield.
The configuration allowed for the operator to reach through the tube to clean with only a one-time pass. The CS designation is for a chip shield which will protect the operator from any excess debris and coolant. With the model 1206SS-24-CS, the operator could now pick up a tube, use the Soft-Grip Back Blow Safety Air Gun to remove the debris and coolant from within the round tubes, square tubes and rectangle tubes. Also, they did not have to worry about changing the rags when it got dirty. What an amazing purchase for this company, as they increased the speed of the cleaning operation by 70% without affecting the inside finish of the stainless-steel tubes.
If you need to clean the inside of tubes, hoses, pipes, etc., EXAIR has the perfect nozzle for you, the Back Blow Air Nozzles. EXAIR can attach these nozzles on our VariBlast Compact, Soft Grip and Heavy Duty Safety Air Guns for easy-to-use manual operations. For this customer above, they were glad that they contacted EXAIR about their application. If you require more details, you can share your application with an Application Engineer at EXAIR. We will be happy to help.
The other day I received a call from the Corporate Director of a manufacturing company with multiple locations across the country. He had grown frustrated with the service and quality he was receiving from his current Air Gun & Nozzle supplier. He explained that he was unable to buy the individual components to make repairs to the air guns and described the overall quality as “disposable”.
I asked him for model air gun he had been purchasing so that I could make an accurate comparison and recommendation for the equivalent or better EXAIR offering. As I researched this competitive air gun I was surprised to find out that the specifications were vague at best. What I mean by that is EXAIR clearly publishes air consumption @ 80 PSI, force which is specified @ 12″ from the nozzle and the sound level in dBA @ 3′ from the nozzle.
The customer reported an average noise reduction of over 15 dBA which looks considerable, however it is a greater gain than the number would indicate. An increase of 10 dB is required before sound is perceived to be twice as loud, therefore EXAIR lowered the perceived sound by over 150%!

One of the easiest ways to find out if your compressed air guns are safe for operation is by looking at the nozzle. First, take your current compressed air gun and disconnect it from the compressed air line. Second, look directly into the end of the nozzle where the air comes out. If you can see the inside of the nozzle, then your air gun or blow-off device is unsafe. Nine out of ten compressed air guns are considered to be dangerous. In this blog, I will go through the dangers and violations of compressed air guns and nozzles that are very common in the market place.
Occupational Safety and Health Administration, OSHA, is an organization that enforces standards for safe and healthy working environments. They have training, outreach programs, and educational assistance for manufacturing plant. But, they will also enforce these standards with heavy fines for violations. The two most common violations with compressed air guns and nozzles are 29CFR 1910.242(b) for dead-end pressure/chip shielding and 29CFR 1910.65(a) for maximum allowable noise exposure. If you are unfortunate in receiving an audit, the OSHA agent will target your compressed air guns and blow-off devices.
Here is the first example of a nozzle that I would like to discuss. As you can see, there is only one opening where the air can come out from the nozzle. Other types of nozzles that would fall into this category will include copper pipes, extensions, or worn nozzles. They are dangerous as the compressed air cannot escape if it is blocked by your skin. An air embolism could occur within the body which can cause bodily harm or death. If operated above 30 PSIG (2 bar), these nozzles would violate the OSHA 29CFR 1910.242(b) for dead-end pressure. This is a hazard which can be avoided by using EXAIR Super Air Nozzles and Safety Air Guns. The nozzles are designed to utilize fins to allow air to escape and not penetrate your skin. With EXAIR products, you will not violate this standard even if you go above the 30 PSIG (2 bar).
To counteract the dead-end pressure violation, some nozzle manufacturers created a hole through the side of the nozzle (Reference photo below). This will allow for the compressed air to escape, but, now the issue is noise level. With an “open” section in the nozzle, the compressed air is very turbulent and very loud. They state that 70% to 80% of all hearing loss within a manufacturing plant is caused by compressed air. For this, OSHA 29CFR 1910.65(a) was created to show the maximum allowable noise exposure. This chart shows the time and noise limits before requiring hearing protection. The EXAIR Super Air Nozzles are designed to have laminar flow which is very quiet. With our typical Safety Air Gun, model 1210, the sound level is only 74 dBA; well under the noise exposure limit for 8 hours.
Why do I bring these points up? Because safety is everyone’s responsibility. The National Institute for Occupational Safety and Health, NIOSH, has an overview of how to handle hazards in the workplace. They call it the Hierarchy of Controls (click). This is a means to best protect workers from dangers. The most effective way is by eliminating the hazard or substituting the hazard. The least effective way is with Personal Protective Equipment, or PPE. For your unsafe compressed air nozzles and guns, EXAIR can help by substituting the hazardous air gun and nozzle with an engineered solution designed with safety in mind.
In my opening statement, I explained a quick and easy method to determine if your compressed air guns are dangerous. To keep your company compliant and safe, EXAIR offers a variety of different types of nozzles and Safety Air Guns to best fit your requirement. If you find that you are using hazardous blowing equipment, you can contact an Application Engineer to find a safe and effective alternative.
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.
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.
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.
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.
