Engineered Compressed Air Products = Less Noise & Money Saved

Everyone dislikes loud noises for the most part. Here in Ohio we just got done surviving the constant buzz and swarming of cicadas. We all deal with noise on a daily basis, some of it enjoyable and some of it not so much. Noise is an inescapable fact of life and all we can do is try to reduce noise level to save our sanity. But, did you know that cutting down on the noise produced by compressed air blow offs can actually save you money? Your loud homemade blow off system is not only way too loud, but it is most likely also costing you more money than you need to spend.

EXAIR’s engineered compressed air products are designed to operate quietly and efficiently. The reduction in noise they produce is only one of the benefits – another is the reduction in money by reducing compressed air use.

But how does one calculate out the ROI? 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 typical ROI preformed and replaced with a corresponding EXAIR Super Air Nozzle:

  • ¼” drilled pipe with (3) 3/32” Holes which uses 9.4 SCFM per hole at 80 psig (denoted as DP)
  • A Model 110003 3” Super Air Knife can be used to replace and only uses 8.7 SCFM at 80 psig (denoted below as SAK)

Calculation:

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

(28.2) * (60) * (8) * (5) * (52) = 3,519,360 SCF

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

 (8.7) * (60) * (8) * (5) * (52) = 1,085,760 SCF

Air Savings:

SCF used per year for DP – SCF used per year for SAK = SCF Savings

               3,519,360 SCF – 1,085,760 SCF = 2,433,600 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

                                (2,433,600 SCF) * ($0.25 */ 1000 SCF) = $608.40 annual Savings

With the simple investment of $216 (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

                                ($608.40/year) / (5 days/week * 52 weeks/year) = $2.34 per day

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

                                ($216) / ($2.34/day) = 92.3 days 

As you can see it doesn’t take long for the air knife to pay for itself. You also get better overall performance as the Super Air Knife will provide a solid curtain of air. In the end you get to breathe a sigh of relief as no more jump scares and a loud hiss when you turn your air on. Who doesn’t like to save a little money and sanity, especially in these crazy times?
