## The Impressive ROI of an Engineered Air Nozzle

You may have asked…why should I switch over to an engineered air nozzle if my system already works? Or…How can air nozzles be much different?

Manufacturing has always been an advocate for cost savings, where they even have job positions solely focused on cost savings. Return on Investment (ROI) is a metric they look toward to help make good decisions for cost savings.  The term is used to determine the financial benefits associated with the use of more efficient products or processes compared to what you are currently using. This is like looking at your homes heating costs and then changing out to energy efficient windows and better insulation. The upfront cost might be high but the amount of money you will save over time is worth it.

But how is ROI calculated? It is very simple to calculate out your potential savings of using one of EXAIR’s Intelligent Engineered Compressed Air Products. If you would rather not do the calculations out yourself then we can do it for you by sending the item in question to our Efficiency Lab Testing. The Efficiency Lab Testing is a free service that we offer to show you the possible savings by switching to one of our products.

The following is a simple ROI  calculation for replacing open blowoffs with an EXAIR Super Air Nozzle:

• ¼” Copper Pipe consumes 33 SCFM at 80 psig (denoted below as CP)
• A Model 1100 ¼” Super Air Nozzle can be used to replace and only uses 14 SCFM at 80 psig (denoted below as EP)

Calculation:

(CP air consumption) * (60 min/hr) * (8 hr/day) * (5 days/week) * (52 weeks/year) = SCF used per year for Copper Pipe

(33) * (60) * (8) * (5) * (52) = 4,118,400 SCF

(EP air consumption) * (60 min/hr) * (8 hr/day) * (5 days/week) * (52 weeks/year) = SCF used per year for EXAIR Product

(14) * (60) * (8) * (5) * (52) = 1,747,200 SCF

Air Savings:

SCF used per year for Copper Pipe – SCF used per year for EXAIR Product = SCF Savings

4,118,400 SCF – 1,747,200 SCF = 2,371,200 SCF in savings

If you know the facilities cost to generate 1,000 SCF of compressed air you can calculate out how much this will cost you would save. If not, you can us \$0.25 to generate 1,000 SCF which is the value used by the U.S. Department of Energy to estimate costs.

Yearly Savings:

(SCF Saved) * (Cost / 1000 SCF) = Yearly Savings

(2,371,200 SCF) * (\$0.25 / 1000 SCF) = \$592.80 annual Savings

With the simple investment of \$42 (as of date published) you can calculate out the time it will take to pay off the unit.

Time Until payoff:

(Yearly Savings) / (5 days/week * 52 weeks/year) = Daily Savings

(\$592.80/year) / (5 days/week * 52 weeks/year) = \$2.28 per day

(Cost of EXAIR Unit) / (Daily Savings) = Days until product has been paid off

(\$42) / (\$2.28/day) = 17.9 days

As you can see it doesn’t have to take long for the nozzle to pay for itself, and then continue to contribute toward your bottom line.
