In case it goes unnoticed, EXAIR focuses on engineered compressed air point of use products to ensure that our customers are utilizing their costly utility as efficiently as possible.  The main benefits to purchasing EXAIR products are the support you receive from us at EXAIR, the quality of the product, the savings in compressed air, and the increase in safety.  Another added benefit is a large number of utility companies are offering rebates on the purchase of engineered nozzles, just like the Super Air Nozzles that EXAIR offers.

Many energy providers offer these energy rebates for commercial or industrial users.  Here in the Cincinnati area, Duke Energy offers rebates on items such as lighting, air compressors, engineered air nozzles, heaters / dryers for extrusion machines, energy management systems, variable frequency drives, data center equipment, even food service equipment, custom incentives, and many other items.

For each engineered compressed air nozzle that is installed, in order to meet the rebate requirements they must flow less than or equal to given flow rates in SCFM at 80 psig inlet pressure. The pipe sizes, flow rates, and EXAIR equivalents are shown below.

EXAIR Engineered Air Nozzle Part Number	EXAIR Flow Rate @ 80 psig
#1102/#1103 – 1/8 NPT	10 SCFM
#1100/#1101 – 1/4 NPT	14 SCFM
#1108SS-NPT/#1109SS-NPT/#1110SS-NPT All are 1/8 NPT	2.5, 4.9, 8.3 SCFM respectively
#1003 – 3/8 NPT	18 SCFM

By just replacing the nozzles the customer saved 2.7 SCFM per nozzle.If we take an example such as the EXAIR Case Study  shown below for 1/4″ copper tube that was being used as an open ended blow off.  The copper tubes were consuming 19.6 SCFM at 100 psig inlet pressure, there were 10 machines with one line per machine operating 40 hours, 52 weeks per year.   The customer retrofitted the open pipes with a model 1100 Super air nozzle and was able to reduce the air consumption by 2.7 SCFM per nozzle.  If they were to purchase these nozzles this year, current list price for a model 1100 Super Air Nozzle is $36.00 USD, then apply for the energy rebate offered by Duke Energy and receive $20.00 per nozzle replaced.  The total savings and return on investment is shown below.

10 nozzles x 2.7 SCFM = 27 SCFM  x 60 minutes per hour x 8 hours per day x 5 days per week x 52 weeks per year = 3,369,600 SCF of compressed air saved per year.

3,369,600 / 1,000 SCF x $.25 = $842.40 USD savings in compressed air per year.

Cost Savings per week = $16.20 USD

Total purchase cost is  $36.00 x 10 nozzles = $360.00 USD

Energy Rebate = @20.00 per nozzle x 10 nozzles  = $200.00 USD in rebates.

$360.00 USD purchase price – $200.00 USD energy rebate = $160.00 USD final purchase cost.

Return on investment at a savings of  $16.20 USD per week is

$160.00 / $16.20 = Less than 10 weeks pay back!

By applying for the energy rebate this customer could reduce the ROI of this air savings project from just over 22 weeks (which is still very good) to less than 10 weeks.

If you would like to learn more about whether there are Industrial energy rebates available in your area, contact an Application Engineer and let us know where you are located and who your energy provider is.

We will help you determine the correct engineered solution to save your compressed air as well as help you to apply for eligible energy rebates in your area.
