How Can You Benefit from EXAIR’s Efficiency Lab?

How many times have you purchased a new product and worried if it was the right choice? Well EXAIR can provide that confidence using our calibrated testing equipment to compare your current product to an EXAIR product, in our Efficiency Lab. Whenever I needed a new process or product I would spend countless hours researching how will this benefit me, my employer or my customer? Research is not only time consuming but also very costly.

EXAIR believes in their product so much that we offer an Efficiency Lab where we will test your production product and help show that our products will not only work for you, but also show that they can save money, as well as make your work environment a safer place.

EXAIR has provided performance values (force, noise, air consumption, ROI) for many of our products. We make purchasing from EXAIR fun because you know in advance that our products will meet or exceed your expectations. Further backing up our commitment with the Efficiency Lab we offer an 30 Day Unconditional Guarantee. EXAIR believes in our products and want to make your purchase a risk free process.

We can test the performance of your current product to EXAIRs Intelligent Compressed Air products for air consumption, force, noise levels… and provide a comprehensive report of our analysis, including simple ROI.  

What does our Efficiency Lab cost? EXAIR believes in our products so much, that this is a free service to our customers. Simply call and talk to one of our Application Engineers at 800.903.9247 or you can send an email to lab@exair.com or visit www.exair.com and talk on our live help. If you feel we can help with a comparison them simply send your product(s) freight prepaid to EXAIR Corporation attention to our Efficiency Lab. All trials will be on a confidential basis unless you provide permission to share.

Process Improvement, ROI and Safety from One Air Nozzle

Process improvement projects can be detailed, complex, expensive, and take a long time to prove their worth.  Today, I want to tell you about one that WAS NOT ANYTHING like that.

A metal stamping company used compressed air to blow their products from their dies.  They did what many do – they ran some copper tubing, and aimed it at the platen so it would properly eject the parts as they were stamped.  They KNEW it was loud, and they suspected it was inefficient as well.

After discussing the setup and seeing a picture of it (the one on the left, below,) I recommended installing a few engineered Super Air Nozzles to lower the noise levels considerably.  Boy, was I wrong.  About “a few” nozzles, that is…turns out, they only needed one Model 1122-9212 2″ Flat Super Air Nozzle with 12″ Stay Set Hose.  The copper tubes come from a manifold that already had 1/4 NPT ports – installation took a matter of minutes.  Nothing detailed, complex, or expensive about it:

This loud & inefficient copper tubing blowoff was just a compression fitting (and a Model 1122 2″ Flat Super Air Nozzle) away from being quiet and efficient.

It didn’t take much longer than that to prove its worth either: as soon as they noticed how much the noise level went down on THIS press, they ordered them for the other eighteen presses in their facility as well.

The 1/4″ copper tubes blew continuously from a pressure regulator set @60psig…the three of them theoretically consumed a total of ~80 SCFM.  The Model 1122, at 60psig supply, consumes only 17.2 SCFM.  Simple return on investment was as follows:

  • 80 SCFM was costing them $48.00 a week
    • 80 SCFM X 60 min/hr X 8 hr/day X 5 days/week X $0.25/1,000 CFM = $48.00
  • 17.2 SCFM, using the same formula, only costs $10.32 a week (I’ll let you do the math; it’s good practice.)
  • They saved $37.68 a week.  The Model 1122-9212 costs $116.00 (2020 pricing) – that means that each of them paid for themselves in just a hair over three weeks.
  • $37.68 x 50 work weeks per year = $1884.00 saved annually per nozzle
  • $1884 x 18 (the number of presses) = $33,912 saved annually 

Considering they also didn’t have to listen to those very loud open ended copper tube blowoffs, I think you’ll have to agree it made for a very good investment.  They did. The new nozzle runs at 77 decibels, a comfortable level and well below the OSHA standard [29 CFR – 1910.95(a)] for allowable noise exposure.

If you’d like to find out how EXAIR Intelligent Compressed Air Products can save you money on compressed air – and save everyone’s hearing – give me a call.

EXAIR’s Return on Investment For One Engineered Air Nozzle is Amazing!

Return on Investment (ROI) is a measure of the gain (preferably) or loss generated relative to the amount of money that was invested.  ROI is typically expressed as a percentage and is generally used for financial decisions, examining the profitability of a company, or comparing different investments.  It can also be used to evaluate a project or process improvement to decide whether spending money on a project makes sense.  The formula is shown below-

ROI
ROI Calculation
  • A negative ROI says the project would result in an overall loss of money
  • An ROI at zero is neither a loss or gain scenario
  • A positive ROI is a beneficial result, and the larger the value the greater the gain
1100group
Our catalog publishes most products’ performance and specification data for a compressed air supply pressure of 80psig.

Example – installing a Super Air Nozzles (14 SCFM compressed air consumption) in place of 1/4″ open pipe (33 SCFM of air consumption consumption) .  Using the Cost Savings Calculator on the EXAIR website, model 1100 nozzle will save $1,710 in energy costs. The model 1100 nozzle costs $42, assuming a $5 compression fitting and $45 in labor to install, the result is a Cost of Investment of $92.00. The ROI calculation for Year one is-

ROI2

ROI = 1,759% – a very large and positive value.  Payback time is only 13 working days!

If you have questions regarding ROI and need help in determining the gain and cost from invest values for a project that includes an EXAIR Intelligent Compressed Air® Product, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.

Air Savings Calculator

I received an email from an engineer that was looking at our Super Air Nozzles.  They currently were using four blow-off lines that were made from 6mm ID copper tubes. The system was designed to blow out holes after machining.  The engineer was in charge of the task of optimizing 25 machining stations similar to this one.  He was familiar with EXAIR products from his previous employment, and he recognized the waste of compressed air by using open pipe.  He purchased four Nano Super Air Nozzle, model 1110SS, for a trial.  He was impressed with the performance, the low sound level, and the engineered design in safety.  But, for upper management in his company, he had to show a cost savings in order to change all the stations in the facility.  He asked me to help him in calculating the compressed air savings.

nano nozzle

He gave me some additional details about their application.  He was using the compressed air about 30% of the time throughout an 8 hour day at a pressure of 80 PISG.  He wanted to present the savings per day, week, and year as well as the payback period in his evaluation.  I have performed many of these calculations for other customers and was happy to help.  It is sometimes easier to speak in terms of savings, as everyone can relate to money, especially management.

Knowns:

Flow: 1110SS Nano Super Air Nozzle – 8.3 SCFM at 80 PSIG

Flow:  6mm ID copper tube – 42 SCFM at 80 PSIG

This is where the COST SAVINGS CALCULATOR on our website shines!

The Calculator tells us you will see a ROI (Return on investment) is less than 5 days! And will save you $3,033.00 over a full year on compressed air generation cost alone!

Don’t be fooled by the initial cost of a tube, pipe, drilled holes, or a substandard nozzle.  You can see by the facts above, if you use any additional compressed air in your blow-off application, it will cost you a lot of money in the long run.  If you need any help in calculating how much money EXAIR products can save you, you can use our Air Savings Calculator from our website, or you contact an Application Engineer at EXAIR.  We will be happy to help you.
