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 operators experiencing fatigue.
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 toward 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 over them.
With EXAIR’s Heavy Duty Safety Air Gun, you can still achieve the high forces required for tough applications without the risk of injuries to personnel. Do yourselves and your operators a favor and get one on order today!
Nozzle Guard protects the Super Air Nozzle from damage that could be caused by incidental contact during use.
Gate Valve option for easy flow adjustment by the operator, with a simple twist of the ring!
Rugged AND comfortable elastomer grip with pushbutton trigger for optimal ergonomics.
These, combined with the features they share with our four most powerful Super Blast Safety Air Guns (high force, automatic shutoff, 3 and 6 foot extensions) make it one of the most innovative blow off products on the market today. With all that going for the TurboBlasts, we still want to emphasize that they’re offered as an enhancement to – and not a replacement for – the Super Blast line. Consider:
Super Air Nozzle Clusters. Because of the Nozzle Guard, Clusters aren’t offered with the TurboBlast products. Clusters concentrate their high force, powerful airflow on a smaller target area than comparable single Super Air Nozzles:
Spring-To-Close Ball Valve. While the ergonomic, pilot actuated pushbutton trigger on the TurboBlast Safety Air Guns is likely to be preferred in a number of situations, the full hand grip of the Super Blast Safety Air Gun’s ball valve proves to be more suitable for certain positions, like when the device is to be operated above shoulder height:
EXAIR is in the business of helping you get the most out of our products – and your compressed air system. If you have questions, I welcome the opportunity to help…give me a call.
A few weeks ago I got a call from a large North American manufacturer of Strut Columns. They recently got a large recall on products they were shipping because metal chips and debris were causing the oil seals to wear and leak prematurely. They found that the manufacturing process could leave chips clinging to the inside diameter (ID) of the outer tube and would make it past there visual inspection. They wanted an option to design into a robotic “cleaning station” where the ID would get cleaned while the outside features were getting cleaned as well. Well for me it was pretty easy to select the EXAIRBack Blow Nozzles!
We offer three different sizes to fit inside a wide variety of diameters from ¼” (6.3mm) to 16” (406mm) ID. They are designed to clean tubing, pipes, hoses, channels, and extruded “odd” shapes. The 360o rear airflow pattern can “wipe” without touching the internal surface to remove coolant and chips. For the application above, I recommended the model 1006SS Back Blow Air Nozzle to fit inside the 2″ (51mm) opening. The range for this Back Blow Air Nozzle is from 7/8” (22mm) to 4” (102mm) inside diameters. This 316SS robust nozzle would last a long time without having to change or replace.
At first they purchased a hand held system on one of our Heavy Duty Safety air guns, This gave them the ability to test the concept out and they found it worked great wiping the ID clean of all unwanted debris. They used the 1306SS-12-CS, this gun with the 12″ extension and chip guard gave them a great platform to test!
Once they wrapped their testing up, they replaced this manual operation with just the nozzle on a 1.5″ schedule 40 pipe. The nozzle was mounted on the end and a robot would slide the part ID over the nozzle!
This $117.00 nozzle was able to fix an issue that caused hundreds if thousands of dollars in recalls! That’s why we take time and intelligently design our nozzles, the 1006SS was designed for these type of applications and it excels in them!
Using Engineered nozzles can make a big difference in the function of your processes – not only to your financial bottom line, but to everyone’s safety, health, and livelihood. If you’d like to find out more about how EXAIR can help, give me a call.
If you look at operating costs alone, compressed air can be just about the most inefficient method there is for cleaning parts. If you just look at the risks, it’s potentially very dangerous too. Don’t even get me started on the insufferable noise it can make.
For cleaning parts, most folks are familiar with the use of an air gun. You can find the simplest of these in many industrial settings: a valve (often in the form of a handheld trigger device) fitted with a nozzle of some sort (often in the form of an open ended tube, pipe, or fitting to focus or direct the air flow). These have all three of the “downsides” I opened this blog with. Of course, these concerns can be mitigated to a high degree by using the right tool for the job. That’s where engineered products like EXAIR Safety Air Guns come in. Let’s look at how we can address these three “downsides”:
Efficiency: This is all about compressed air consumption. In the simplest of air guns mentioned above, consumption is only limited by the passages in the valve (or trigger) and the discharge fitting…and those limits are usually negligible. Modifying the ends (see examples below) to focus the air flow usually has minimal effect, because you’re not appreciably changing the total cross sectional area of the discharge opening:
Safety: Remember learning about kinetic and potential energy in grade school? Well, when you compress air to 100psig, fitting all that air into a much smaller space creates a TREMENDOUS amount of potential energy:
One problem with the thumb guns above is, if you were to jam into the palm of your hand and pull the trigger, a large component of that potential energy (pressure) turns into kinetic energy (force)…more than enough to break the skin and cause a potentially fatal condition known as an air embolism. In the United States, OSHA (Occupational Safety and Health Administration) regulates compressed air devices used for cleaning purposes. All EXAIR Safety Air Guns comply with Standard 1910.242(b) by providing a relief path to ensure that it cannot be dead ended, and thus never create over 30psi measurable at the outlet)
Noise: Another problem is, another component is turned into sound pressure…discharging air from a direct opening is quite loud. OSHA standards address these with limitations on outlet pressure and sound level. All EXAIR Safety Air Guns comply with Standard 1910.242(b), which limits the outlet pressure (by providing a relief path to ensure that it cannot be dead ended, and thus never create over 30psi measurable at the outlet) and all but our largest Super Blast Safety Air Guns comply with Standard 1910.95(a) limits for continuous 8 hour sound level exposure.
Which brings us to the topic of this blog: How exactly did THEY (our customer who used to use the thumb guns above) select the right Safety Air Gun, and how can we apply that to getting the right Safety Air Gun for YOU?
These steps aren’t all-inclusive, and they don’t necessarily need to be followed in order, but if you call an EXAIR Application Engineer about selecting a Safety Air Gun, here’s what we’re gonna talk about:
Airflow pattern: Honestly, I could make a good case for this being the first consideration. Selection of any blowoff product – be it an Air Nozzle, Air Amplifier, Air Knife, Air Wipe, etc., will largely depend on the size and shape of the airflow.
For the most precise, focused blowoff, our Atto Super Air Nozzle (top left) is a great choice. It’s available on:
When stubborn, heavy, and/or LOTS of debris needs to be absolutely, positively blown off RIGHT NOW, our High Force Super Air Nozzles may be just what you need. Our largest; Model 1120 1-1/4 NPT Super Air Nozzle, is shown (above right). The High Force Super Air Nozzles are offered on:
Soft Grip or Heavy Duty Safety Air Gun (up to 3.3 pounds of force over a 6.3″ wide area @12″ away)
Application specific concerns: Everything we’ve discussed so far has involved aiming the blow off stream away from the operator, in the direction the device is aimed. In addition to wide variety of engineered Air Nozzles, EXAIR offers a number of options for these products:
If you’re looking for a portable, hand-held compressed air blow off product that’s quiet, safe, and efficient, look no further than EXAIR Corporation’s extensive line of Safety Air Guns. If you’d like to find out more, give me a call.
