EXAIR Efficiency Lab at Your Service

I couldn’t count the number of times we have written a blog about the EXAIR Efficiency Lab because its that cool, unlike the number of wins the Cincinnati Reds have right now. I can count that on two hand 10………10-26 as of writing this blog and I could go on and on about the pain but I will spare you the tears and write about how amazing the Efficiency lab is for any company that utilizes compressed air!

Is the Mascot signing something? Or hanging his head? We will never Know!

First – what is the EXAIR Efficiency Lab? Well several years ago EXAIR created a free program called the Efficiency Lab.  This program is to compare your current pneumatic blow-off device with an EXAIR engineered product.  The values we compare are air consumption, noise level and force. We generate a detailed report to send to you for review.  It is a free service that EXAIR provides for U.S. and Canadian companies to know more details about solutions you are currently using in your processes.

The EXAIR Efficiency Lab

Why do we offer this?  Air Compressors demand significant electrical power and compressed air is considered to be a fourth utility within plants and industries.  Many people do not realize the cost and safety concerns when using improper blow-off devices.  As an example, if you look at a single 1/8” open pipe for blowing compressed air, it can cost you over $2,000 a year to operate.  This will add to your overhead and cut profits.  Another reason to consider your blow-off device is that compressed air can be dangerous.  With that same 1/8” open pipe, it can violate OSHA standards for noise exposure and dead-end pressure.  In deciding your “vehicle” for blowing compressed air, cheap is not typically best option.  To put it in other terms, a cheap nozzle is like a cheap old car, it’s cheap because it gets 3 MPG with faulty brakes.

With our Efficiency Lab, a comparison it is quite simple to do.  An easy way is to call us and explain the details. These details can be data such as the inside diameter and length of a an open tube you are using, or the actual performance data of a cheap air nozzle you have chosen to use. Perhaps the easiest way to make the comparison is to let EXAIR do it – send in your blowoff product or a sample of the tube, nozzle, modified fitting, etc. We will then put them through our testing process. You can also fill out our Product Efficiency Survey on our website to give the conditions for testing. 

We will run the tests at the specified conditions or in a range of settings.  We will then return your pneumatic device back to you at our cost with a detailed report of the comparison.  Your information will be confidential, and we will not share it without your permission.  We will also provide a simple ROI – many customers like to use this report to show managers, executives, HSE, etc. on the improvements that EXAIR can provide including cost savings and safety.

How do we do the Efficiency Lab?  We use calibrated equipment and standardized procedures to test for noise levels, flow usage, and force measurements.  We will recommend an EXAIR engineered solution as a replacement to your current device to do the comparison.  With the analytical information, we can also figure the total amount of air savings, return on investment, payback period and safety improvements.

Don’t Swing and miss…. (Like the Reds)  You do not want to sacrifice safety, time, and money with a sub-standard product.  Let EXAIR solve this dilemma with our free service; the Efficiency Lab.  Take advantage of our expertise by using the Efficiency Lab service, we will provide you a detailed report with a comparison analysis to make a great choice.

EXAIR’s Efficiency Lab Shows How Much Compressed Air You Can Save

The EXAIR Efficiency Lab

EXAIR has been manufacturing compressed air products since 1983, and we created a culture of making high quality products that are safe, effective, and very efficient.  Since we stand by our products, we created a program called the Efficiency Lab.  This program is to compare your current pneumatic blow-off device with an EXAIR engineered product.  The values we compare are air consumption, noise level and force. We generate a detailed report to send to you for review.  It is a free service that EXAIR provides for U.S. and Canadian companies to know more details about solutions you are currently using in your processes.

What is Laminar Flow and Turbulent Flow?

Super Air Knife

Fluid mechanics is the field that studies the properties of fluids in various states.  There are two areas, fluid statics and fluid dynamics.  Fluid dynamics studies the forces on a fluid, either as a liquid or a gas, during motion.  Osborne Reynolds, an Irish innovator, popularized this dynamic with a dimensionless number, Re. This number determines the state in which the fluid is moving; either laminar flow or turbulent flow.  Equation 1 shows the relationship between the inertial forces of the fluid as compared to the viscous forces.

Equation 1:  Re = V * Dh/u

Re – Reynolds Number (no dimensions)

V – Velocity (feet/sec or meters/sec)

Dh – hydraulic diameter (feet or meters)

u – Kinematic Viscosity (feet^2/sec or meter^2/sec)

The value of Re will mark the region in which the fluid (liquid or gas) is moving.  If the Reynolds number, Re, is below 2300, then it is considered to be laminar (streamline and predictable).  If Re is greater than 4000, then it is considered to be turbulent (chaotic and violent).  The area between these two numbers is the transitional area where you can have eddy currents and some non-linear velocities.  To better show the differences between each state, I have a picture below that shows water flowing from a drain pipe into a channel.  The water is loud and disorderly; traveling in different directions, even upstream.  With the high velocity of water coming out of the drain pipe, the inertial forces are greater than the viscosity of the water.  This indicates turbulent flow with a Reynolds number larger than 4000.  As the water flows into the mouth of the river after the channel, the waves transform from a disorderly mess into a more uniform stream.  This is the transitional region.  A bit further downstream, the stream becomes calm and quiet, flowing in the same direction.  This is laminar flow.  Air is also a fluid, and it will behave in a similar way depending on the Reynolds number.

Turbulent to Laminar Water

Why is this important to know?  In certain applications, one state may be better suited than the other.  For mixing, suspension and heat transfer; turbulent flows are better.  But, when it comes to effective blowing, lower pressure drops and reduced noise levels; laminar flows are better.  In many compressed air applications, the laminar region is the best method to generate a strong force efficiently and quietly.  EXAIR offers a large line of products, including the Super Air Knives and Super Air Nozzles that utilizes that laminar flow for compressed air applications.  If you would like to discuss further how laminar flows could benefit your process, an EXAIR Application Engineer will be happy to help you.

EXAIR’s Efficiency Lab: A Service Providing ROI

EXAIR’s Free Efficiency Lab

Have you ever stood at a dealership wondering what car to buy?  You have a variety of things to consider like safety, gas mileage, quality and price.  But what if the dealership had a professional race car driver to test each car for you and give you a detailed report about each one?  That would definitely help you to make a better choice.  At EXAIR, we are that professional driver when it comes to compressed air products.

EXAIR has been manufacturing compressed air products since 1983, and we created a culture of making high quality products that are safe, effective, and very efficient.  Since we stand by our products, we created a program called the Efficiency Lab.  This program is to compare your current pneumatic blow-off device with an EXAIR engineered product.  We generate a detailed report to send to you for review.  It is a free service that EXAIR provides for U.S. and Canadian companies to “test drive” your current pneumatic blow-off items.

Why do we offer this?  Air Compressors use a lot of electrical power and are considered to be a fourth utility within plants and industries.  Many people do not realize the cost and safety concerns when using improper blow-off devices.  As an example, if you look at a single 1/8” open pipe for blowing compressed air, it can cost you over $2,000 a year to operate.  This will add to your overhead and cut profits.  Another reason to consider your blow-off device is that compressed air can be dangerous.  With that same 1/8” open pipe, it can violate OSHA standards in noise exposure and dead-end pressure.  In deciding your “vehicle” for blowing compressed air, cheap is not the best option.  In reference to my analogy above, it would be like buying a car that gets 3 MPG with faulty brakes.

With our Efficiency Lab, it is quite simple to do.  For starters, you can go to our Product Efficiency Survey on our website to give the conditions for testing.  If you wish for a side by side analysis, you can place your pneumatic device in a box and send it to EXAIR.  We will run the tests at the specified conditions or in a range of settings.  We will then return your pneumatic device back to you at our cost with a detailed report of the comparison.  Your information will be confidential, and we will not share it without your permission.  Many customers like to use this report to show managers, executives, HSE, etc. on the improvements that EXAIR can provide in cost savings and safety.
