Once you’ve selected an engineered compressed air nozzle for your blowoff application, you’ll likely need a solution to mount and position it as well. In some applications you may be able to simply replace the old solution with a similar thread, but if the installation is a bit more complex, or if it is a new installation entirely, you’ll need a means to do so. Here’s where EXAIR’s Stay Set Hoses and Magnetic Bases come into play.
EXAIR’s Stay Set Hoses are available from 6”-36” in length with ¼ NPT male threads on each end, or a ¼ NPT male on one end and 1/8 NPT female on the other. The Stay Set Hoses are rigid and allow you to maintain precise positioning of the blow off nozzle. The hoses have “memory” and will not creep or bend. They’re easily repositioned as well, making them an ideal solution for applications that may require moving them around due to varying parts.
Stay Set Hoses can also be installed on any Soft Grip Safety Air Gun. Simply adding a suffix to the end of the any of the Soft Grip Air Gun model numbers will come with the Stay Set Hose installed. For example, the gun below is a Model 1230-36SSH. A Model 1230 Safety Air Gun, with a 36” Stay Set Hose installed. Having a Stay Set Hose on your air gun can allow you to reach into tight or awkward places that a traditional air gun won’t permit.
In addition to the Stay Set Hoses, EXAIR also has Magnetic Bases available as well. The powerful magnet permits both horizontal and vertical mounting. A manual valve is also included that will allow you to vary the force and flow. Magnetic bases are available with one or two outlets and can be combined with any of our nozzles and Stay Set Hoses to create your own customized blowoff system.
No matter the application, EXAIR has a solution for your blowoff. Give an Application Engineer a call today and we’ll help you determine EXACTLY what you’ll need with all parts available from stock!
There is rarely a day that goes by that I don’t receive a call from someone who has a need for a compressed air product and when I state the SCFM requirements of the device they respond back with the psi rating of their air compressor. Many technicians simply do not understand the difference between the two. Simply put psi (pounds square inch) is force and CFM (cubic feet per minute) is flow.
A simple illustration would be to contrast a 12 VDC powered air compressor that many people carry in their trunks to inflate car tires. They will inflate your car tire to 35 psi in a matter of minutes. While the air compressor at a tire shop can inflate a car tire in a minute or less. What is the difference?
Simply put, the flow. Both inflate the tire to the desired pressure but the one with largest flow (volume) does it much faster. In the case of a compressed air product such as an air nozzle, the pressure required to operate is only one part of what is necessary to operate the device effectively, you need to have enough flow or CFM.
Let us now consider an EXAIR 1100 Super Air Nozzle, its rated performance of 13 ounces of force at 12″ distance from the nozzle is derived from supplying 14 SCFM @ 80 psi. The typical home use air compressor that runs on 110 VAC (Generally 2 HP maximum) will not generate the flow (volume /CFM) at 80 psi to run the nozzle at peak force, just as it would not generate enough flow to fill the tire as quickly as the industrial compressor at a tire shop.
When an open tube, pipe or inefficient nozzle is placed at the end of an air line to provide blow off for cooling or cleaning it demands much greater volume from the compressor. If the compressor cannot keep up the force (pressure) of the system will decline. Replacing an open tube or pipe with an EXAIR engineered nozzle will require less compressed air volume which, in turn, will give the compressor more ability to provide full pressure and force upon your application.
If you would like to discuss air consumption of any of EXAIR’s engineered solutions, I would enjoy hearing from you…give me a call.
In rugged industrial environments the EXAIR Heavy Duty Safety Air Gun delivers powerful blasts of compressed air right where it is needed. It features a 3/8 NPT metal inlet to allow for increased air flow to the Super Air Nozzle of your choice and there are many configurations are available from stock. It is constructed of a durable and robust cast aluminum body with an ergonomic and comfortable composite grip that allows for extended use without fatigue.
The Heavy Duty Safety Air Gun can be configured with extensions that are available in 6” increments up to 24” in length and 12” increments from 24” up to 72”. Combine the extension with our optional Chip Shield for maximum operator safety and comfort.
We offer a wide variety of nozzles to allow you to configure the Heavy Duty Safety Air Gun to you specific application. EXAIR has a large selection of nozzles that are engineered to entrain surrounding air with the compressed air supply creating a synergistic blast that is very powerful. Most importantly they operate much quieter than the limits of OSHA standard 29 CFR 1910.95(a) and can’t be “dead ended” therefore meeting OSHA standard 29 CFR 1910.242(b).
The EXAIR Heavy Duty Safety Air Gun is available in the configurations shown below or many others. If you have an application you would like to discuss or to see how the Heavy Duty Safety Air Guns will improve your process, give us a call, we are happy to help.
This week in Cincinnati we hit a record high 79°F. Since less than a week earlier it snowed all afternoon, let’s just say many people around here began to get excited. While I don’t mind a little snow here and there, once February begins to draw to a close I’m ready to bust out the shorts, tank tops and flip flops and bring on some warmer temperatures. It also means I’m right around the corner from opening up the pool. Let’s hope that goes much smoother than last year….
Another benefit to the warmer temperatures, especially here in Cincinnati, is the coming of the baseball season. With the Reds Spring Training also starting this week, optimism is in the air (albeit reserved after the last few years performance).
Unlike baseball where it’s 3 strikes and youuuu’rrrreeee out! EXAIR’s unconditional 30 day guarantee for all stock products allows you the opportunity to test out several different solutions to ensure you get the right product for your application.
I recently worked with a customer that was interested in switching their current blowoff process with something that would reduce their sound levels but still allow them to complete the job in a similar time frame. The company makes aluminum castings and was using the air gun to remove residual sand leftover in the die after each cycle. Their current air gun was producing sound levels at 107 dBA, well above OSHA’s safe operating range for a full 8 hour shift of work according to OSHA 29 CFR 1910.95(a).
They didn’t want to commit to just one style of air gun, so he purchased a 1210SS-18 (Safety Air Gun w/ ¼ NPT Stainless Steel Nozzle and 18” extension) and a few different additional ¼ NPT nozzles to see which style his operators preferred. After some testing, they concluded that the air gun with an 1122SS 2” Flat Nozzle installed provided them with the best results. Having the added feature of changing out the shim to increase/decrease the force and flow was also welcomed. They’ll be returning the extra nozzles and applying the credit to the purchase of some new 1230SS-18 guns to outfit their other work stations.
While we do have a highly trained team of Application Engineers ready and available to help you determine the most suitable product, sometimes testing it out at your facility is the best way to ensure a positive result. That is EXACTLY why we give you 30 days to test out any stock product. If for any reason at all you’re unsatisfied with the performance, give us a call and we’ll arrange for a return. Don’t be afraid to swing and miss!
Even if you’re a casual reader of our blogs, you already know that EXAIR Application Engineers LOVE to preach efficiency in the use of compressed air…it’s our “bread and butter;” the very nature of our business. This year, we’re celebrating thirty-five years of leading the way in the development of efficient, safe, and quiet compressed air products. Our track record of success as a solutions provider across a diverse range of industrial and commercial applications is well documented in our blogs, as well as Knowledge Base and Case Study Libraries. We devote considerable resources (engineering, research & development, product testing, etc.) to making certain that EXAIR Intelligent Compressed Air Products cost less to operate, and perform better, than whatever you’re using right now.
Strange as it may seem, though, sometimes our products are EXTREMELY popular in cases where they INCREASE a facility’s consumption of compressed air…by replacing something that DOESN’T use compressed air at all:
*I’ve written before about how our Large Maximum Cold Temperature Vortex Tubes have replaced liquid nitrogen rigs in freeze sealing operations. Now, a Vortex Tube directs a portion of its air supply to (usually) unusable hot exhaust, in order to generate the usable flow of cold air. When compared to the costs of liquid nitrogen and the resources involved to get it where it needs to be, though, the cost of the compressed air needed to operate the Vortex Tube is indeed the practical solution.
*Line Vacs are probably THE prime example of the value of using compressed air where it wasn’t used before…replacing a “bucket and ladder” operation:
*Then there are the situations that just come down to time. In large spaces, our Super Blast Safety Air Guns can be used to “sweep” the floor in a fraction of the time it takes an operator with a push broom.
To make a long story just a little bit longer…if you’re using compressed air, you can use it better with EXAIR’s engineered compressed air products. And there are plenty of practical applications where you’re not using compressed air right now too. If you’d like to find out more about either one, give me a call.
I was recently contacted by a Chicken Farm in Canada about a blow off application for cleaning the dust and debris off the walls and ceilings in their barns. They currently use a 185 SCFM portable, engine driven compressor and a lance made from 3/4″ open copper tube. The barns are rather large, approximately 10′ high by 500′ long, and they place the compressor in the middle of the barn and have a 250′ length of hose going to the homemade blowoff. This setup worked fine for a minute or so but then the airflow would start to weaken at the point-of-use and the compressor would run continuously as it wasn’t able to maintain pressure to keep up with the demand of the copper pipe.
After discussing the details of the application, I recommend the customer use our Model # 1214-6 Super Blast Safety Air Gun with 6′ aluminum extension. This would reduce the air demand to 91 SCFM, more suitable for use with the existing 185 SCFM compressor.
The design of the Super Blast Safety Air Gun features a spring loaded manual valve, providing automatic shutoff and a comfortable foam grip. The 6′ extension provides the extra reach they need to effectively treat the walls and ceilings in the barn.
The Super Blast Safety Air Guns are ideal for wide coverage, long distance applications. They use our Large Super Air Nozzles and Super Air Nozzle Clusters, providing forces levels from 3.2 lbs. up to 23 lbs, depending on which nozzle is fitted on the assembly. Air inlets range from 3/8 FNPT up to 1-1/4 FNPT and aluminum extensions are available in 36″ or 72″ lengths.
If you have any questions or need further assistance, please contact an application engineer.
The following short video is a brief overview of our VariBlast Compact Safety Air Gun. The VariBlast Compact Safety Air Gun’s unique design features a variable flow trigger allowing you to achieve varying levels of force from the same nozzle.
