What’s in it for me? We’ve probably all asked this question at some point or another, especially when trying to justify a big change or expenditure. Is it going to be worth it? What benefit am I going to get out of it?
Here at EXAIR we are confident that there is a lot to gain from using our products. Two of the biggest benefits of our Intelligent Compressed Air Products are a reduction in noise, and a reduction in Compressed Air usage. The latter will often lead to big money savings. Many times the savings our products offer will pay for the product itself! This is where ROI calculations come in. What is my Return on Investment going to be?

So, how do you calculate your ROI? The easy answer is that you don’t have to! You can use our Air Savings Calculator to calculate your savings for you. If you know your current air consumption (in SCFM), the new air consumption (SCFM) and the cost of the product, our calculator will turn that into monetary savings, as well as the calculated payback time in days.

Another option, if you would rather not do the calculations yourself, is that you can send the item in question to our Efficiency Lab. The Efficiency Lab Testing is a free service that we offer to show you the possible savings by switching to one of our products. We will calculate the savings for you and send you the results of our findings.
The final option – my favorite by the way – is that we can do the math right here:

For a simple example of a blowoff application, I’m going to show the ROI of replacing a drilled copper pipe with an EXAIR Super Air Knife. The calculations will be as follows:

Copper Pipe (1/4”): 3x 3/32” diameter drilled holes uses 9.4scfm per hole (28.2scfm total) at 80psig.

3” Super Air Knife: uses 8.7scfm at 80psig

Calculation:

For the yearly consumption, we need to find how many minutes in a year the blowoff will be operated:

For the Copper Pipe, the yearly consumption would be:

For the 3” Super Air Knife, the yearly consumption would be:

The difference between these two:

At this point, if you know your facilities cost to generate 1,000scf, you can use that to calculate how much you would save. For this example, we will use $0.25 to generate 1,000scf, which is used by the U.S. Department of Energy to estimate costs. This gives the following yearly savings:

With an investment of $273.00 (at the time of publishing), you can calculate the time it would take to pay off the unit:

From these numbers you can see that after only 117 days the 3” Super Air Knife will have paid for itself. After that, it is all money being put towards your bottom line.
