Hot Off The Press (Release): EXAIR Catalog #35

Published on by Russ BowmanLeave a comment

If you’re a registered user on our website, you likely got word of this already through our August 15, 2023 Press Release. If not – or even if you did and want some more details – read on, and I’ll tell you all about it.

Like all of our previous catalogs, Catalog #35 provides specification, dimensional, and performance data on all of our stock products. Many of them include detailed descriptions of “textbook” applications for those products. You’ll also find:

  • Efficiency Lab (page 6): If you want a full performance report on a compressed air device you’re using right now, this is a free service we offer. Contact an Application Engineer and arrange to have it sent in. We’ll test it for compressed air consumption, force applied, and sound level, and send you a report on it. It’ll include, of course, the EXAIR engineered product(s) that we’ll recommend, along with performance data on them, as a comparison.
  • Our Six Steps (page 7): The first page of our Optimization section details the Six Steps To Optimizing Your Compressed Air System. It’s not necessary to follow them in order, and not all of them are applicable to every single compressed air system. But if you’re serious about reducing your compressed air costs, this is a comprehensive plan on how to do it for sure.
  • OSHA Maximum Allowable Noise Exposure table & typical Air Consumption values of common “homemade” blow offs (page 53): We put this here so you can turn the next few pages and see what a difference engineered products like EXAIR Super Air Nozzles can make.
  • Droplet Size data (page 98): Use this to determine the suitability of our Atomizing Spray Nozzles for liquid spraying applications.
  • Vortex Tube Specification and Performance tables (pages 201-202): If you know how much cold air flow you need, and at what temperature you need it, you can use these tables to determine which EXAIR Vortex Tube (or other Spot Cooling Product) to use.
  • Cabinet Cooler System Sizing Guide (page 220): Just fill in the blanks & send this in, and we’ll quickly & accurately calculate the heat load of your electrical/electronic enclosure, and specify the right Cabinet Cooler System for you.

Now, if you’ve ever had any of our previous catalogs, you might have noticed that those were already in there, and that’s all pretty great. What’s REALLY great about Catalog #35, though, is some of the new features:

  • Line Vac Conveyance Data (pages 176-177): While there’s WAY too many variables in bulk conveyance applications to accurately calculate conveyance rates. We’ve done some controlled, in-house testing with several different materials, several different Line Vacs, at several different lengths & heights, though, and we’re proud to publish that in the new catalog. This shouldn’t be considered a guarantee of performance, but if you’re wondering how much of a particular bulk material you can convey, this table will certainly get you in the right ballpark.
  • Best Practice for Using EXAIR Intelligent Compressed Air Products (pages 239-240): This information has always been in the Air Data files on our website, along with an ABUNDANCE of data that’ll help you get the most out of your compressed air system. Now, it’s at your fingers.

Of course, I’d be remiss if I wrote a whole blog on the new catalog without mentioning the new products:

  • Model 9207 Ultrasonic Leak Detector (pages 18-19): This serves the same function as the now-obsolete Model 9061, but with some handy upgrades like a LED display, a sleek new body, and high quality ear buds.
Use the Model 9207 Ultrasonic Leak Detector’s parabola to find the vicinity of the leak, and the tubular extension to identify its exact location.
  • 1/2 NPT HollowStream Cone Atomizing Nozzles (page 105): With five new distinct models at the high-flow end of our already comprehensive line of Liquid Atomizing Spray Nozzles, these provide up to 53 gallons per minute of liquid flow, and are capable of passing particulate up to 0.344″ in diameter.
The Hollow Cone spray pattern is ideal for cooling, cleaning, foam breaking, rinsing, and dust suppression. It also uses considerably less liquid than the FullStream models, when higher flow rate isn’t necessary.
EXAIR’s ATEX Cabinet Cooler Systems provide heat protection for electrical enclosures in potentially explosive atmospheres, like those found on offshore drilling platforms, petrochemical plants, mines, flour mills, etc.

Like our previous catalogs, Catalog 35 is now available for download (in product line sections due to file size) from the PDF Library at EXAIR.com. You can also request a copy to be mailed to you, or you can contact an Application Engineer to have individual product line sections (again, because of file size) email to you right away.

As always, if you’d like to talk about how to get the most out of your compressed air system, our team of Application Engineers are here Monday to Friday, 7am to 4pm Eastern, to help with that. Give me a call.

EXAIR’s Heavy Duty Safety Air Gun’s: Powerful and Safe

Published on by Jordan T ShouseLeave a comment

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.

1350-6-CS – Heavy Duty Safety Air Gun with Model 1104 Air Nozzle, 6″ Alum. Ext Pipe & Chip Shield

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.

Compressed air goes in the back, as it exits the front ambient air is entrained in the total flow of air you are getting.

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.

Safety Air Gun Extensions

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!

Pressure Monitoring Not Just For Air Systems

Published on by Brian FarnoLeave a comment

This past weekend we celebrated Labor Day. My family and I had the pleasure of going to a friend’s property and parking an RV to “glamp” for the weekend. The trip is only about 3-1/2 hours from our homes and when traveling in the RV it is a slow and steady wins the race kind of trip. One of the first things I do when we are prepping for the trip is to check tire pressure. Then, the last thing I do before we leave is check tire pressures.

While at their property we did the same on all of their vehicles, two side-by-side UTVs, and their boat trailer. When looking at each of these, almost all of them were low. Now, these items all sit more than they are used and only see movement maybe once a month. The weather here in the area, including Kentucky has been getting cooler in the evenings which causes the air in tires to start to take up less space and so the pressure drops. Well, after checking and filling, we went out and everything was great, until it wasn’t. When we loaded up the boat we noticed one of the tires was nearly on the rim of the trailer. With no tools on hand and a short drive, we elected to make the drive and inspect when we got back to home ground rather than in a public parking lot where someone had already offered to help if need be. Once we arrived, we inspected the tire and found no obvious signs for it to be so low on pressure. We filled it up again and let it sit for the night. After breakfast the next day we found the tire was still holding air so we assumed that when we checked the pressure initially it was at a good pressure and by doing so something must have stuck in the valve causing it to have a slow leak. Once that was seated and good, the tire held air, and we were good to roll for another day.

This made me realize how important pressure monitoring is on tires for certain vehicles and led me to install a continuous pressure monitoring system on the RV that we took. Being able to monitor tire temperature and pressure is critical and catching low pressure before it causes other issues can help reduce damage or catastrophic failure significantly. This also all made me connect my thoughts to the EXAIR Digital Flowmeters which are available with pressure sensing capabilities. These can easily be installed into a system and then be used to monitor your industrial system and potentially see issues before catastrophic failures or downtimes due to a loss of compressed air.

If you want to discuss what a Pressure Sensing Digital Flowmeter can do in your facility or even if you want to troubleshoot why you are seeing a drop in performance and how to even go about troubleshooting your entire air system, don’t hesitate to contact an Application Engineer.

What Makes EXAIR Safety Air Guns So Safe?

Published on by Russ BowmanLeave a comment

In 1970, the United States Congress passed the Occupational Safety and Health Act. This Act created both the Occupational Safety and Health Administration (OSHA) and the National Institute of Occupational Safety and Health (NIOSH). The goal of both organizations is to ensure that workers, in any industry or field, have adequate protection from physical injury and health risks associated with the tools & equipment they operate, and environmental hazards in the spaces in which they operate. Workplace safety was a big deal to them.

Fifty plus years on, workplace safety is still a big deal, and not just to the federal government. At EXAIR, we have a program of continuing training on any and all safety concerns relevant to what we do here. This includes everything from pedestrian safety (not getting hit by a delivery truck in the parking lot, or a fork truck in the shop) to hazard communication (understanding the labels and safety data sheets for the cleaning compounds, adhesives, etc. used in the facility) to the procedures & personal protection equipment required for the use of compressed air products. Workplace safety is, and always has been, a big deal to us.

This culture of safety carries over to the design of our products as well. It’s arguably most important when we’re talking about products that operators hold in their hands…like our Safety Air Guns. To answer the question I posed in the title above, let’s consider the features of these products:

Engineered Air Nozzles: Regardless of any other features, the energy associated with the flow & force of the compressed air exiting the device is the first concern, and rightly so. Without a method of reducing the static pressure at the point of discharge to 30psi or less, there’ll be enough energy in the air flow to potentially break the skin if the device’s tip was dead-ended, with no place for that pressure to go. You can either reduce the supply pressure to 30psig or less (which means you’re not going to get a heck of a lot done unless it’s just lightweight debris you’re blowing off, AND you can get close enough to it), or you can use products like our Super Air Nozzles, which provide a relief path for that air flow, so the static pressure at the point of discharge never reaches 30psi, no matter what the supply pressure is. The design of all of our engineered Air Nozzles provides such a relief path, which complies with OSHA Standard 1910.242(b), which regulates the use of compressed air for cleaning…which is what almost all air guns are used for.

If you did this without that Super Air Nozzle on the end, and the air supply pressure was greater than 30psig, it could break the skin and cause a potentially fatal condition called an air embolism.

Ergonomic design: Across the board, a key feature in the design of EXAIR Safety Air Guns is to be easy on the hands, with comfortable grips and easy to pull triggers. From the molded thermoplastic construction of the VariBlast Precision models, to the cast aluminum construction of the VariBlast Compact, Soft Grip, Heavy Duty, and TurboBlast models, they’re all lightweight, and quite durable as well.

From small part cleaning by hand, to wide area blowoff, and all points in between, EXAIR has a Safety Air Gun for most any application.

Engineered Air Nozzles part 2: The same design features that prevent them from being dead-ended also result in remarkable attenuation of the sound level generated by the air flow. By entraining an enormous amount of air from the surrounding environment (which results in a much lower operating cost than open-end type air guns), a lower velocity boundary layer develops around the higher velocity center air flow, resulting in much quieter operation. All but our largest Super Air Nozzles are compliant with OSHA Standard 1910.95 limits for maximum allowable noise exposure.

EXAIR Super Air Nozzle entrainment

Chip Shields: OSHA Standard 1910.242(b), in addition to limiting dead-end pressure to prevent air embolisms from breaking the skin, also calls for “effective chip guarding” to prevent airborne debris being blown off by high velocity air flow from hitting the operator. This can be accomplished by the user via glove boxes (similar to a small parts sandblasting booth), a physical barrier like a piece of shatter resistant glass, plexiglass, Lexan, etc., or personal protective equipment like aprons, long gloves, or face shields. In case any of that is impractical, EXAIR has Chip Shields that fit our VariBlast Precision, VariBlast Compact, Soft Grip, and Heavy Duty Safety Air Guns. They’re clear polycarbonate discs that can be moved back & forth on a rigid aluminum extension pipe on the Safety Air Gun, so you can position them according to the needs of the application.

If workplace safety is as big a deal to you as it is to OSHA and EXAIR, I strongly recommend looking at what you’re using for handheld blow off applications right now, and how they stack up against EXAIR’s comprehensive line of Safety Air Guns. If you’d like to find out more, give me a call.
