Published on by jasonkirbyLeave a comment

At EXAIR, we are committed to providing our customers with the necessary tools to tackle challenges and enhance their workforce training through a comprehensive array of resources known as the Knowledge Base. This collection is systematically organized by various criteria to deliver practical, experience-driven solutions.

In our Knowledge Base, you will discover case studies that showcase how we have assisted customers in enhancing their processes, reducing compressed air consumption to save costs, and improving worker safety. So, today, I would like to discuss how to participate in our case study program, and the opportunity to save up to $1,500.

Our case study program is open to all user type customers, looking to improve their application. The only requirements are to show quantifiable data explaining how improvements were made and photos of the EXAIR solution in the application. This data can show cost savings, time savings, or overall process improvement. Below is a completed case study showing how the use of EXAIR 1122 2″ Flat Super Air Nozzles reduced air consumption and sound levels. Using model 1122, 2″ Flat Super AIr Nozzles, this customer is estimated to save $4,177.63 per year.

Identify Real Compressed Air Savings Through EXAIR’s Efficiency Lab

Published on by Tyler DanielLeave a comment

Many customers may not have the means to test the air consumption of their blowoff solutions. With compressed air being the most expensive utility in a manufacturing facility, it’s important to identify places where you can save money on your overall operating costs. EXAIR manufactures a wide variety of products intended to help you reduce your compressed air usage. If you’re not able to accurately measure the consumption in your own shop, we invite you to send the products to EXAIR for testing. With EXAIR’s Award-Winning Efficiency Lab, just simply box them up and send them to our warehouse in Cincinnati, Ohio.

Once we receive it, our engineers will complete some in-depth testing to determine the compressed air consumption, sound level, and force that your current solution provides. With this information, we’ll be able to compare it to an EXAIR Engineered Solution. This way, we ensure that you receive the best, safest solution possible also capable of saving money through reduced air consumption and improved efficiency.  We’ll send you back a comprehensive report that’ll help you to make the best decision for your company.

I’ve recently been working with a customer that sent in one of the nozzles they’re using across all their CNC machines. They wanted us to test it out and see if we’d be able to offer them something that could reduce their overall compressed air usage. The nozzle was one of the cheap plastic varieties and was attached to a commonly used modular hose. This type of modular hose is not designed for operating under high pressures. These hoses are more suitable for liquid coolant or air that is at or below atmospheric pressure.

After testing, we found that at 80 psig the nozzle consumed 3.85 SCFM and produced a force of 1.92 oz. We also noticed that after 60 psig, the nozzle began to leak due to a poor seal where the nozzle met the brass hex. The EXAIR nozzle most suitable to replace this was the 1108SS. At just 2.5 SCFM at 80 psig, replacing the plastic nozzle with an engineered solution saves them 35% of their overall consumption for this blowoff. With close to 1000 of these nozzles in operation, the air savings can add up quickly!!

In addition to increasing efficiency, replacing these nozzles also greatly increases overall worker safety. The sound level is reduced from 73 dBA to just 58 dBA and EXAIR’s nozzles also adhere to OSHA 1910.242(b). The plastic nozzles could be dead-ended, posing a hazard that can result in costly fines. These fines are assessed per infraction, so having multiple non-compliant nozzles can easily get very expensive if you’re subject to an unannounced visit by an OSHA inspector.

If you think you may have an opportunity to improve upon your existing blowoff methods, give us a call. We’ll be happy to take a closer look and have you send the product back to EXAIR for a quick trial in our Efficiency Lab. You’ll be glad you did!

Calculating Return On Investment with EXAIR Products

Published on by Russ BowmanLeave a comment

Just because something works, doesn’t necessarily mean it works as well as it could. We talk to folks every day who have compressed air-operated devices that work OK, but they’re loud. Or they’re not compliant with safety regulations. Or they use too much compressed air. EXAIR has solutions to all of those issues, but it’s that last one that I want to spend some time on today.

A caller was using a drilled pipe to clean blow off a conveyor – it was 36″ wide, so the pipe had (72) 1/16″ diameter holes drilled, one every 1/2″ along the pipe length. It used compressed air at a rate of 261 SCFM with a supply pressure of 60psig. We can use a US Department of Energy thumb rule which states that it costs $0.25 to generate 1,000 Standard Cubic Feet of compressed air to determine the annual operating cost of this drilled pipe, which they operate eight hours a day, 250 days a year:

261 SCFM X 60 min/hr X 8 hr/day X 250 days/yr X $0.25/1,000 SCF = $7,830.00 annual cost

Here’s a typical drilled pipe that we tested for a customer in our Efficiency Lab.

A 36″ Super Air Knife only uses 82.8 SCFM @60psig. Using the same math:

82.8 SCFM X 60 min/hr X 8 hr/day X 250 days/yr X $0.25/1,000 SCF = $2,484.00 annual cost

Now we have the data to use our Return on Investment calculation:

Gain from investment: $7,830.00 (drilled pipe cost) – $2,484.00 (Super Air Knife cost) = $5,346.00

Cost of investment: 2024 price for a Model 110036 36″ Aluminum Super Air Knife = $938.00

A 470% annual return is spectacular by any measure. To further put that in perspective, let’s calculate how long it takes for the Air Knife to pay for itself. The 36″ Aluminum Super Air Knife costs $938.00 (2024 price), and the annual savings in compressed air cost are $5,346.00:

$938.00 (spent) ÷ $5,346.00 (saved/yr) = 0.18 years

Since we used 250 days – 5 days/week for 52 weeks, less 10 days for holidays, maintenance, etc.:

0.18 years X 250 days/year = 45 days

So, in about a month and a half, they saved as much as they spent on the Super Air Knife. We’ve worked with customers who have seen their return on investment in just a few days, or as long as a year or so. Regardless, if it costs less to operate, you’re still moving in the right direction. If you’d like to find out how much you can save – and how fast you can pay off your investment – you can do the math above, or you can use our Online Calculators, or you can give me a call.

Oh, and if you don’t have the air consumption data on what you’re using now, we can measure that for you in our Efficiency Lab. It’s a free service we offer, without obligation to purchase anything, for anyone who wants to know the performance level of their air-operated blow off devices.
