A Journey of Learning: Passing the CCASS Certification Test

Published on by Jordan T ShouseLeave a comment

Hey everyone! I’m beyond excited to share some big news with you—I recently passed the Certified Compressed Air System Specialist (CCASS) certification test! It’s been a wild ride getting here, and I want to take you through my journey, to show what this certificate means to me.

Why CCASS? Six and a half years ago, I started my fascination with compressed air products and systems—how they power so much of modern industry, from manufacturing to automation. But I’ll be honest: there’s a lot to learn, and I wanted a way to prove I really get it. That’s where the CCASS certification came in. Offered by CAGI, it’s a credential that shows you’ve mastered the ins and outs of compressed air systems—think system design, energy efficiency, and all the components that make it tick. For me, it was about more than just a title; it was a chance to level up my skills and help customers optimize their systems.

The CCASS exam isn’t a walk in the park—it’s 80 multiple-choice questions in just 1.5 hours, testing your applied knowledge, skills, and abilities. CAGI doesn’t hand you a study guide, but they do point you to some resources. Their “Body of Knowledge” list was my starting point, packed with references like the Compressed Air & Gas Handbook and standards like ASME EA-4 for energy assessments. I dove into those, soaking up everything from compressor basics to sustainability tips.

What does this mean? Well, I’m the 6th person on the application engineering team to become certified. Our team of Application Engineers are dedicated to continuous self-improvement and actively seek ways to assure our readers, clients, and prospective customers that we are the foremost authorities in engineered solutions for point-of-use compressed air. We prioritize ongoing education and share our expertise through various platforms. This includes informative blogs like this one, casual videos available on our YouTube Channel and website, articles in different publications, and our webinars.

The subjects we cover range from strategies to reduce waste associated with one of the most costly utilities to system designs that mitigate pressure drops and ensure adequate supply for point-of-use applications. We can provide both in-depth analysis and high-level overviews to cater to different levels of understanding.

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.

How To Calculate Your Return On Investment From Using Engineered Compressed Air Products

Published on by Russ BowmanLeave a comment

There’s an old saying that goes “If it isn’t broken, don’t fix it.” Best case, this means it may not be necessary to repair, refurbish, or replace something just because there’s a newer offering on the market. Worst case, it’s used to justify continued use of something when the aforementioned repair, refurbishment, or replacement will result in quantifiable benefits. THAT makes THIS quote all the more applicable:

“The most dangerous phrase in the English language is: We’ve always done it this way. It raises the question, ‘Are we doing this because we always have, or because it’s the right thing to do?’”
-Grace Hopper, Rear Admiral USN & computer pioneer

If you consider “not spending any more than you have to on compressed air” to be “the right thing to do”, then this blog’s for you. Read on, and we’ll calculate not only how much you might save by using engineered compressed air products in place of what you’re using now, but how soon that amount you save will equal how much you spent on those products…that’s called Return On Investment, or ROI. Let’s work through an example:

A popular air gun fitted with a cross-drilled nozzle for OSHA compliance uses 34 SCFM @80psig. These are commonly replaced by our Model 1210 Soft Grip Safety Air Guns fitted with our Super Air Nozzles, which consume only 14 SCFM @80psig. It’s not likely that the trigger on an Air Gun used for blowing, cleaning, drying, etc., will be pulled continuously, but we can assume that two hours of “trigger time” per day (for an eight-hour shift) is reasonable. Here’s how to calculate annual savings:

(34-14 SCFM) X 60 min/hr X 2 hrs/day X 5 days/wk X 50 wks/yr=600,000 Standard Cubic Feet saved

Model 1210 Soft Grip Safety Air is fitted with an EXAIR Super Air Nozzle. We can also supply it with a Rigid Extension and Chip Shield (right).

Now, we need to determine the cost of your compressed air. The calculation for that, per the U.S. Department of Energy, is as follows:

Cost ($) = {bhp X 0.746 X # of operating hours X $/kWh X % time X % full load bhp}/motor efficiency

Where:
bhp = motor full load horsepower
0.746 = conversion from hp to kW
% time = percentage of run time at this operating level
% full load bhp = brake horsepower as percentage of full load bhp at this operating level
Motor efficiency = motor efficiency at this operating level

For simplicity, you could also get a fairly accurate answer by applying an “industry standard” thumb rule which states that a typical industrial air compressor generates ~4 SCFM per HP. If you know your electricity cost ($/kWh), you can calculate the cost of compressed air generation as follows. To keep most of the digits to the left of the decimal point, it’s commonly calculated as $ per 1,000 Standard Cubic Feet:

$/kWh X 0.746 hp/kW ÷ 4 hp/SCFM ÷ 60 min/hr X 1,000 = $ per 1,000 SCF

For EXTRA simplicity, you can use ANOTHER thumb rule, also endorsed by the Department of Energy, which states that compressed air costs about $0.25 per 1,000 SCF. It uses the above formula, and a typical estimate for electricity cost of $0.08 per kWh which my buddy Brian Farno did the math and provided a detailed explanation on that one here. So:

600,000 SCF X $0.25/1,000 SCF = $150.00 saved by switching to the EXAIR Safety Air Gun

Given the cost (current 2023 List Price) of $115.00 for the Model 1210 Soft Grip Safety Air Gun, we can calculate Return On Investment as a function of time…how long it takes before you end up saving the amount you spent:

$115.00 saved ÷ $150.00 spent X 12 months in a year = 9.2 months

At EXAIR (if you hadn’t figured it out already), we LOVE to do the math, but if you don’t (no judgment), we’ve got calculators on our website for that. Just fill in a few blanks, and get your answer. If there’s anything I can help with, though, give me a call.
