Video Blog: Laminar and Turbulent Flows

I have written blogs about laminar and turbulent flows as related to the Reynold’s number.  Now, let’s demonstrate the difference between the two flows and the advantages of laminar flow from EXAIR’s engineered air nozzles; as demonstrated by our VariBlast Safety Air Gun.

Video blog : VariBlast Compact Safety Air Gun

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.

If you have any questions, please  contact an application engineer at 800-903-9247.

Video Blog: EXAIR Efficiency Lab

The video below is a brief introduction to the EXAIR Efficiency Lab, a free service provided by EXAIR for customers within the USA and Canada.

If you have a single point blowoff that does not have an engineered nozzle, or if you have a wider format blowoff, manifold or home-made drilled pipe, contact an Application Engineer with EXAIR and let us help you to reduce your energy waste. Following are some examples of product where we have helped to save some serious air and reduced noise levels which heightens employee comfort.

Use The Force…Or Not…It’s Up To You, Really

The month of May, in 1977, was a great time to be ten years old. I was finishing up my fifth grade year, a pivotal one, thanks to Miss Walker, who ended up being my favorite teacher ever. She had a pet rat named A.J. that we took turns taking home for the weekend. She rewarded us for class performance by taking us outside to play softball on warm & sunny spring afternoons. I trace my love for math (and hence, my inspiration for a career in engineering) to the excitement she instilled in me for the subject…I was among the first to master the multiplication tables.

And then there was Star Wars. There were commercials for the movie and the toys and the merchandise on TV; I swear they ran every five minutes. A fast food chain released a series of posters (free with purchase) and every time a new one came out, Miss Walker promptly hung it on the classroom wall. None of us, her included, could hardly wait until the premiere. I could go on (and on and on and on,) but suffice it to say (for the purposes of this blog,) I’ve been a BIG fan ever since.

Which brings us to today…opening day for “Star Wars, Episode VII: The Force Awakens.” The first time, by the way, a Star Wars movie hasn’t premiered in the month of May, but I digress. The 10 year old inside me wants to go see it RIGHT NOW, but the grownup I have to be has a company Christmas party, two Boy Scout events, and a pre-holiday “honey-do” list to attend to first.

Of course, the “other” epic space movie series couldn’t resist launching THEIR new trailer this week…

All this talk about The Force (capital “F”) and the fact that I write this blog on company time has me thinking about compressed air applications that involve force (lower case “f”) and how using force (unlike “The Force”) is not always prudent.

This is the case in just about any blow off application that uses air under pressure. Open ended copper tubing, drilled pipes, etc., are common and easy ways to discharge compressed air for debris removal, drying, or cooling a part. But the fact is, they waste a LOT of the energy devoted to compressing the air by simply turning it into brute force and noise.

This is where EXAIR Intelligent Compressed Air Products(r) come in: by using the energy of the compressed air to entrain air from the surrounding environment, the total air flow is amplified, resulting in a high velocity blast, at minimal consumption. No; it doesn’t have the same amount of force as an open ended discharge device, but most blow off applications don’t need all that much force anyway.

Of course, there ARE situations where you need to use the force, and we’ve got efficient and OSHA compliant ways to do that too: additional shims in Air Knives, Air Wipes & Air Amplifiers, or larger Super Air Nozzles.

“A long time ago, in a galaxy far, far away,” the continuing theme of the Star Wars saga is to use The Force properly. For the past 32 years, the continuing theme at EXAIR is to help you use the force (of your compressed air) properly. Let me know how we can help.

May The Force be with us all…this weekend, and always.
