## 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 Demonstration of Compounding Sound Levels

In industrial settings, having a single air nozzle or other blowoff product is often not the scenario that is seen.  Many applications require multiple points of blowoff, even if not in the same direction or for the same position within the machine.  In the scenario where multiple nozzles are used, sound levels can get tricky to calculate and is often thought of as a mystery.  If you follow our blog then you may have seen this excellent blog that shows all the math behind calculating the total decibels when multiple sources of noise will be present. The video below gives a demonstration of utilizing two of the EXAIR model 1100 – 1/4″ FNPT Super Air Nozzle.

In the video you see a model 1100 being operated and producing a sound level of 74 dBA from 3′ away from the nozzle point.  When the second nozzle is turned on (also producing 74 dBA individually), the pressure is adjusted back up to the same input pressure and the sound level meter registers 78 dBA from 3′ away.  Following the math laid out in the “excellent blog” link above, the sound level calculated comes out to be the same 78 dBA that is shown in the video using EXAIR’s Digital Sound Level Meter.

If you would like help determining the sound levels within your facility, check out the EXAIR Digital Sound Level Meter as well as reach out to an Application Engineer.

## Video Blog: Introducing The EXAIR Drum Cover: Model 6850

Below is a video showcasing the model 6850 Drum Cover.  The Drum Cover is a new product from EXAIR that will help to filter pneumatically conveyed products from the air used to move them.  If you would like to discuss a conveyance application or whether this product would fit your need, please contact an Application Engineer.

## Communication Is Key

Effective communication is a key interpersonal skill and learning how each of us can improve our communication is beneficial to all. Communication is a two way process, so improving communication involves both how we deliver and listen to the message. To best service our customers, EXAIR has many ways to share and receive information.

There are the standard methods, of course, that have been around for years.  Phone and fax are still very useful, and everyone has noticed that fax is slowly becoming less utilized. As dreaded as it may be, email is certainly a valuable way to communicate, especially as it allows ‘attachments’ such as photos, which as the saying goes, are definitely worth a thousand words. If video or 3D models are exchanged I am certain the number of words increases.

The newest technology for communication is via ‘chat’ which can be accessed from the EXAIR website. Here, you can chat with an Application Engineer and do something as simple as confirming a part number to something more involved like sizing a Cabinet Cooler System.

The US Postal System is still a valuable communication tool, as we send out the EXAIR Catalog (currently volume No. 30) and the EXAIR-Mail (Number 109/Fall 2016 issue just went out), and some Purchase Orders still are dropped off by the Postman.

Another method of communication is face to face.  We have what we call the ‘Demo Room’ here at the factory in Cincinnati, OH.  In this room, we have every type of our Intelligent Compressed Air Products, in just about every size offered, ready for demonstration and testing to your application.  We’ve had visitors from all over the world come in and share face to face their applications and collaborate with us and test out the EXAIR solution.

There is also the EXAIR website, where we provide a plethora of information regarding the EXAIR product lines, CAD and PDF librariesCase StudiesPresentations, and the Video Library just to name a few.  Also, here is where you can Request a Catalog, Sign up for E-News, and Check List Pricing.

Lastly, and since you are reading this you already are familiar with the EXAIR Blog – a great way for us to share with you our musings and thoughts, in a way that makes it a personal take on the EXAIR products and our interactions with our customers.

Effective communication is very important to us and what we do here every day.  Feel free to utilize one or more of the Contact Us tools to communicate with us and we’ll be in touch!
