At EXAIR we want to do everything we can to ensure you’re getting the most out of our products. In many applications, we’re offering a replacement for an inefficient or unsafe “homemade” compressed air device. In these cases, replacing the inefficient device with an engineered product by EXAIR often leads to a quick payback time.
To help you understand your compressed air products, EXAIR offers a free Efficiency Lab Service. Simply send in the device your currently using for testing, and one of our qualified Application Engineers will provide you with a comprehensive report. Included in this report is an ROI calculation, so you’ll know down to the day of when your EXAIR Product will begin paying YOU!
For some more information on this service, and a view of the EXAIR Efficiency Lab, check out my video below:
If you believe there’s places in your facility that could benefit from this service give us a call. We’re ready to help you start saving!

EXAIR introduced our first Wet/Dry Vacuum in August. We have simplified the process of converting a vacuum from wet to dry (and dry to wet) materials. This can now be easily switched within 15 seconds due to its patent pending engineering and design. The video below is a quick rundown of just how easy it is to contain any industrial mess with the new compressed air powered vacuum from EXAIR. If you would like to discuss the EasySwitch Vacuum options and kits available from stock, please contact us.
There is hardly a day I work that I am not talking about the importance of properly installed pressure gauges. These small devices can often get overlooked or thought of as not necessary on an installation. When troubleshooting or evaluating the compressed air consumption of an application, this is one of the first items I look for in the installation.
As Russ Bowman shows in the above video discussing proper piping sizes, you can see the importance of properly placed pressure gauges. This shows the worst-case scenario where the pressure drop due to improper line sizes gives the false sense to the operator that they are achieving full line pressure when in fact they are not. In order to accurately measure consumption rates, pressure AT THE INLET (within a few feet) to any compressed air product is necessary, rather than upstream at a point where there may be restrictions or pressure drops between the inlet and the gauge. So how exactly do these analog gauges measure the pressure of the compressed air at the installed locations?
The video below shows a great example of pressure increasing and decreasing moving the Bourdon tube that is connected to the indicating needle. The description that follows goes more in-depth with how these internals function.
Most mechanical gauges utilize a Bourdon-tube. The Bourdon-tube was invented in 1849 by a French watchmaker, Eugéne Bourdon. The movable end of the Bourdon-tube is connected via a pivot pin/link to the lever. The lever is an extension of the sector gear and movement of the lever results in rotation of the sector gear. The sector gear meshes with spur gear (not visible) on the indicator needle axle which passes through the gauge face and holds the indicator needle. Lastly, there is a small hairspring in place to put tension on the gear system to eliminate gear lash and hysteresis.
When the pressure inside the Bourdon-tube increases, the Bourdon-tube will straighten. The amount of straightening that occurs is proportional to the pressure inside the tube. As the tube straightens, the movement engages the link, lever, and gear system that results in the indicator needle sweeping across the gauge.
If you would like to discuss pressure gauges, the best locations to install them, or how much compressed air an application is using at a given pressure, give us a call, email, or chat.
When catapults would hurl stones and projectiles at castles there weren’t thinking of how the stones flew or what could make them fly better, often they went with the “Tim Taylor method” of MORE POWER. It wasn’t until thousands of years later that mathematicians started to talk about gases and liquids and how they react to different scenarios. Things like how does air react to a stone being launched through it. Johann Bernoulli played a significant role and calculated a lot of this out throughout his life and discovered what is now called the Bernoulli Principle.
Bernoulli discovered that when there is an increase in the speed of a fluid, a simultaneous decrease in fluid pressure occurs at the same time. This is what explains how a plane’s wing shape matters. It also can showcase how a curveball coming into the strike zone can fall out and cause an outlandish “STTTeeerriike Three” from the umpire. It is also sometimes confused with the Coandă effect. While both effects have a tremendous impact on our modern lives, the best way I have learned these effects is through videos such as the one below.
As mentioned within the video, there are numerous effects that can closely relate to the Bernoulli effect, the best example I see is the curveball which when implemented correctly can cause a very upset batter, while the pitcher has the game of his or her career.
If you would like to talk about some scientific discoveries that have you puzzled, or if you want to figure out how we can use one of these effects to help your application, contact us.
