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.

EXAIR has been at the forefront of safety and efficiency when it comes to blow-off devices since 1983. We understand the importance of keeping personnel and the workplace safe. Controlling employee’s exposure to hazards is a fundamental method of protecting them. The CDC published a useful guide called “Hierarchy of Controls” detailing five types of control methods as a means to implement effective solutions.
Elimination
Substitution
Engineering controls
Administrative controls
Personal protective equipment (PPE)
Elimination
Elimination removes the hazard from the source. Elimination is at the top of the chart because it is the best way to protect workers. In my previous line of work, we had to use MEK to dilute a solvent-based epoxy. By switching over to a water-based epoxy, we were able to eliminate the chemical hazard from our process. In some situations, this can be a difficult task, but the elimination criteria should be the first thing to review.
Substitution
Substitution is looking for a different but safer modification to the source of the hazard. An example would be static elimination. If we take into consideration an ionization bar to remove static, there are manufacturers that make “hot” bars that will shock the operator if they get too close to the ionizing point. EXAIR Gen4 Ionizing Bars are shockless. By substituting the “hot” bars with EXAIR Gen4 Ionizing Bars, you just removed the shock hazard for your operators. When considering substitution, it is important to compare the new risk of the replacement to the original risk. Remember, we are trying to reduce the potential effects of injuries.
The CDC explains these first two methods with this statement, “Elimination and substitution can be the most difficult actions to adopt into an existing process. These methods are best used at the design or development stage of a work process, place, or tool. At the development stage, elimination and substitution may be the simplest and cheapest options. Another good opportunity to use elimination and substitution is when selecting new equipment or procedures. Prevention through Design is an approach to proactively including prevention when designing work equipment, tools, operations, and spaces.”1
Engineering Controls
Engineering controls are very common. Companies can evaluate an area for hazards and address them with proven controls. This can be as simple as adding light curtains to a stamping machine. Another area would be using compressed air for blow-off applications. EXAIR has been providing engineered products to reduce these hazards. We offer Super Air Nozzles, Safety Air Guns, Super Air Knives, and Air Amplifiers to reduce the noise level and dead-end pressure as found in the OSHA directives 29CFR 1910.65(a) for maximum allowable noise exposure and 29CFR 1910.242(b) for dead-end pressure/chip shielding. By adding an engineered nozzle like our Super Air Nozzle over an open pipe, it will protect your workers, stop OSHA fines, and reduce energy costs.
Administrative Controls
These controls will move personnel or change the process to limit the length of exposure time to the hazard. As you notice, this is toward the bottom of the Hierarchy chart as one of the least effective ways for dealing with a hazard. As an example, an operator is exposed to a blow-off application that has a noise level of 95 dBA. The maximum exposure time allowed by OSHA is 4 hours. So, another operator would have to be placed in that area to work another 4 hours. But, if the company added a Super Air Nozzle to the blow-off device, then the noise level would be reduced to 74 dBA. Now, you can have one operator run the machine for the full 8 hours.
PPE
Personal Protection Equipment, or PPE, is equipment that is purchased to help protect the operators from hazards. What may the problem be? First, you have to train the operators on how to properly use them, as well as trust that they will follow the instruction explicitly. It also adds cost to purchase and maintain them. This is why this method is the least effective.
At EXAIR, we have a statement: “Safety is everyone’s responsibility.” The idea behind the Hierarchy of Controls is to help review hazardous areas and implement safer products. EXAIR can help your company follow the Hierarchy of Controls, to eliminate or reduce the hazards of compressed air usage. Many EXAIR products, including Super Air Knives, Super Air Nozzles, Safety Air Guns, and Air Amplifiers are engineered to meet OSHA standards. If you have questions or want to talk to an EXAIR Application Engineer, please contact us to discuss how our products will be beneficial to your work environment’s safety.
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.
