Optimizing Compressed Air: 6th Step – Lower the Pressure!

Published on by Tyler DanielLeave a comment

The last step in EXAIR’s Six Steps to Optimizing Your Compressed Air System centers around air pressure. Unless you’re controlling your air pressure for each individual application, there’s a strong chance you can achieve quite a bit of savings by lowering the air pressure just upstream.

In any application necessitating the use of compressed air, pressure should be controlled to minimize the air consumption at the point of use. Pressure regulators are available to control the air pressure within the system and throttle the appropriate supply of air to any pneumatic device. As the last of the six steps to optimizing your compressed air system, controlling air at the point of use can often be overlooked.

Pressure Regulators “dial in” performance to get the job done without using more air than necessary.

Pressure regulators utilize a control knob that is turned to either increase/decrease tension on a spring. The spring puts a load on the diaphragm which separates internal air pressure from the ambient pressure. Typically made of a flexible rubber material, these diaphragms react very quickly to changes in the air supply. By either increasing or decreasing the flow of air based on the load on the diaphragm, downstream pressure remains fairly constant.

While one advantage of a pressure regulator is certainly maintaining consistent pressure on your compressed air devices, using them to minimize your pressure can result in dramatic savings to your costs of compressed air. As pressure and flow are directly related, lowering the pressure supplied results in less compressed air usage. EXAIR recommends operating your Intelligent Compressed Air Products at the minimum pressure necessary to achieve a successful application. If you notice a desirable result at a pressure of 60 PSIG, or even less, there’s no need to run full line pressure. In-line point of use pressure regulators are the simplest and most reliable way to allow you to dial down the pressure for any compressed air operated product.

When selecting a pressure regulator for your application, it’s critical that it is appropriately sized to supply adequate volume to the point of use devices downstream. Doing so, minimizes the risk of experiencing “droop”. Droop is a decrease in outlet pressure from the specified setting due to an increase in flow rate.  Droop occurs when the demand at the point of use exceeds the volume of air that the regulator can supply. By ensuring the pressure regulator is rated to deliver a sufficient volume of air, you’ll reduce the chances of experiencing droop. EXAIR offers pressure regulators in kits along with many of our products. We’ve done the hard part for you and made sure they’re properly sized!

CAGI CCASS Certificate Awarded To Our Own John Ball!

Published on by Brian FarnoLeave a comment

I blogged in October 2023 about our 4th team member who had passed the Compressed Air And Gas Institute’s Certified Compressed Air System Specialist test. Once Neal Raker received his CCASS certification, it was only a matter of time before the next one of our International Application Engineers, John Ball, was going to take the plunge, so to say.

John has studied, written content revolving around, and demonstrated his knowledge in the compressed air field for many years before he came to EXAIR and has continued his education ever since, doing the necessary due diligence of studying for and obtaining his CCASS certification. As with Neal, Russ, and Tyler all obtaining this, what kind of value does that add for you our customers, and content consumers?

Certainly, it means you can rely on us to actually know what we are talking about when we make a recommendation to you on a phone call, chat or e-mail. It also means that the content of our informal videos, presentations, and blogs is well researched. We hold ourselves to a higher standard, and we must ensure we continue to improve our knowledge through continuing education or else we will not be able to maintain these types of certifications. Our goal is to help in such a way that you will want to come back for more! When we say our people are our most valuable resource, investing in continuing education is one way we walk the walk.

If you want to experience our help first hand, please contact one of our Application Engineers and give us a try. We would be happy to listen and verify your thought process for an application or perhaps walk you through a few scenarios based on multiple, possible solutions. Many times, there’s more than one right answer. We encourage you to bounce your ideas off of us. Contact an Application Engineer today.

CAGI Certification Times 4

Published on by Brian FarnoLeave a comment

The CAGI CCASS is a professional credential offered by the Compressed Air and Gas Institute (CAGI) to represent mastery in all things compressed air system-related, such as system design, compressed air supply and distribution, energy efficiency, system components, and more. To achieve this credential, individuals must attain not only a certain level of education but complete specified training, testing, and professional experiences all pertaining to the comprehensive knowledge of compressed air systems. Neal Raker is our fourth team member to achieve this certification. So what does this mean for you, our customers, and loyal blog readers?

It means that our staff of Application Engineers are continually improving themselves and looking for ways to ensure our readers, customers, and potential customers that we are the leading experts in the industry regarding engineered solutions for point-of-use compressed air. We continue to educate ourselves and then share our knowledge through various avenues. This can include blogs such as this one, informal videos that are published here, on our YouTube Channel and on our website, articles through various publications, and even our webinars.

These topics range from eliminating waste from one of the most expensive utilities to system designs that prevent pressure drops and lack of supply for point-of-use applications. They can go in-depth or stay high level in order to get just a general understanding of the topic at hand.

If you would like to test our knowledge or see what kind of information we can share with you on your facilities’ compressed air usage, contact an Application Engineer today.

Compressed Air System Optimization – Where Do Receiver Tanks Fit?

Published on by Tyler DanielLeave a comment
SixSteps

The 5th step in the 6 steps to optimizing your compressed air system highlights the use of intermediate storage of compressed air near the point of use. Secondary, or intermediate Receiver tanks are installed in the distribution system to provide a source of compressed air close to the point of use, rather than relying on the output of the compressor.

Compressed air receiver tanks are an integral part to many compressed air distribution systems. Compressed air is stored at a high pressure after drying and filtration, but just upstream of point of use devices. The receiver tank is charged to a pressure higher than what is needed by the system, creating a favorable pressure differential to release compressed air when needed.

Think of a compressed air receiver tank as a “battery”. It stores the compressed air energy within a system to be used in periods of peak demand, helping to maintain a stable compressed air pressure. This improves the overall performance of the compressed air system and helps to prevent pressure drop.

They can be strategically placed to provide a source of compressed air to intermittent high volume compressed air applications. Rather than having to pull from the compressor, a receiver tank can be sized to provide the short-term volume of air for a particular application. In a previous post, we’ve highlighted how to calculate the necessary receiver tank based on the air consumption and duration of the application.

EXAIR offers from stock a 60-gallon receiver tank designed specifically for these higher-usage intermittent types of applications. Model 9500-60 can be installed near the point of high demand so that you have an additional supply of compressed air available for a short duration. The tank comes with mounting feet and is designed to stand up vertically, saving floor space. The tank meets American Society of Mechanical Engineers (ASME) pressure vessel code.

Just this past Spring, EXAIR hosted a live webinar where we discuss how to size, install, and implement secondary storage in your plant’s distribution system. If you missed it, check it out here on our website hosted by my colleague, Russ Bowman.

If you have an application in your facility that’s draining your compressed air system, a receiver tank could be the ideal solution. Give us a call and one of our Application Engineers will be happy to help evaluate your process and determine the most suitably sized receiver tank.
