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.

Golfing with EXAIR Products

Published on by Jordan T ShouseLeave a comment

Well it’s that time of year again, at the time of writing this blog thousands are lining up in Augusta Georgia ready to see the 87th edition of the Masters Tournament! Some go for the high level of talent and golf that is played over four days. Others go for the cheap Concessions foods! I mean come on $1.50 for an egg salad and Pimento Cheese Sandwich! Sign me up!

But here at EXAIR we happen to have a few things that can help you with your Golf Game!

  1. Forgot your Tee? No Worries we have you covered with our E-Vac Vacuum Generators! Check out the video below! (They can also be used to suction cup the ball out of a Gators mouth, RIP Chubbs)

On a serous note, when you’re not using an E-Vac as a golf tee, they are very commonly used in applications for bag and package opening, label placement, vacuum forming, leak testing and pick and place applications.

EXAIR Also has accessories to round out vacuum cup systems including vacuum cups themselves, mufflers, check valves, vacuum tubing and fittings.

2. Stuck in a sand trap and really need to get it with in a foot to knock down that par? Again we have you covered the Line Vacs can convey your ball with in inches of the hole. So all you’ll have to do is just tap it in! (Just below the best clip of Happy Gilmore is the line vac conveying some golf balls!!)

While the line vac could help you take a few strokes off your golf game, they will also help you get rid of your buckets and ladders, for filling and moving product. These small units can move large volumes of material.

They are a perfect solution for moving things like plastic pellets, textiles, food products, pills/tablets, granules and much more. By adding a small amount of compressed air through the directed nozzles on the Line Vac, you will create a vacuum on one end and a high flow of air on the other to lift and or push your material up and over to a new location.

Even though I would love to pull a air compressor behind my cart and see what people say at my local course! Both the Line vacs and E-Vacs have great industry uses. If you have anything you need to move or convey give us a call. We have a team of application engineers here M-F 7AM-4PM!

Line Vac Air Operated Conveyors: What to Know When Specifying

Published on by bdwagesLeave a comment

So you are thinking about using a Line Vac… Is it time to replace that ladder and bucket, and automate? There are many factors involved when deciding to use a conveyor system such as EXAIR Line Vacs. First of all let’s take a look at your product that needs conveyed. Will the integrity of your media be compromised by adding this much air to it? How heavy is it? What type of (how much) surface area does it have?

You know your media better than most. You should be able to answer most of those questions pretty easily, but what about the weight? For the weight, we work best knowing the bulk density, or pounds per cubic foot. If you do not readily know, this is easily found by finding the weight of your media in a box (or container). Then take the total cubic inches of the box (L x W x H) and divide that by 1728 (cubic inches per cubic foot), this will give you the cubic feet of that box. Then you simply divide the weight by the cubic feet, and you now have the density.

Line Vacs can convey many things.

Next we need to focus on your conveyance run. We would like to know what type of container is your product sitting in? A super sack, a hopper, a drum, a box? And where is it going? How far away is the destination hopper, dumpster, assembly station, etc.? This will help us determine the type of fitting or tools necessary to extract or release the media. How high do you need to go? How far horizontally? Our Line Vacs, are amazing, but they do have their limits. We will also need to know if there are any turns, and at what angles. Turns are many times unavoidable, but will have an adverse effect on the conveyance run as the airflow is halted and or deflected. Is there a way to minimize or eliminate the turns?

The final question is; how many pounds per minute do you need to be conveyed?

With the size, mass, and geometry of your parts, along with the vertical lift length, and the horizontal conveyance length, added to the turns and twists, you are just about ready to call one of our our application engineers for recommendations. We have some comparison materials for conveyance rates, to get you close to your actual needs. Here are some published conveyance rates as well:

There is one more part to this equation. What type and size of Line Vac will you need? EXAIR has many types of Line Vacs to choose from. As with most products, we have options that take into consideration the temperature and the abrasiveness of your product. We also have options to fit the type of conveyance hose or pipe you want to use , such as sanitary fittings, or threaded. And since we manufacture these right here in Cincinnati, OH, we can make custom Line Vacs for customers fairly quickly. We have designed and manufactured them with custom bolt on flanges, special materials or inlet sizes to name a few.

EXAIR Line Vacs: For bulk material conveyance through lines from 3/8″ to 6″, in aluminum, 303SS, 316SS, or abrasion resistant hardened alloy, available from stock with the widest variety of connections in the industry.

Please do not hesitate to call. We will be happy to help you with any technical questions about our products.

Why Is Ambient Air Entrainment Needed For Pneumatic Conveyance?

Published on by Brian FarnoLeave a comment

When attempting to convey material pneumatically it can sometimes not work as one may hope. This could be due to the lack of ambient air entrainment to generate the vacuum flow which lifts the material away and moves the material. The video above gives a brief example of this.

If you would like to discuss pneumatic conveying products or processes, please contact us. EXAIR’s Line Vac air operated conveyors are a great solution for manual “bucket and ladder” applications, hopper loading, scrap conveyance, media recovery and more!
