Energy Rebates and EXAIR Products

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.

Duke Energy Rebate

Example of our local energy rebate offering for Engineered Nozzles

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.

Case Study 1561

EXAIR Model 1100 Super Air Nozzle Replaces Open Copper Pipe Blow Off

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.

Will Water Move Through EXAIR Air Knives and Air Wipes? (Images included)

Today, I would like to discuss a question that comes up time and time again over the years.  “What happens when I put water through a Super Air Knife?” That raised another question from myself of what about a Super Air Wipe?

The answer is quite simple, it will come out, just not as good as compressed air does.   The engineering and design for Super Air Knives were all based around compressed air use.  With any good product of course comes the question in time, how else can we use this?   A number of applications for the Super Air Knife is blowing moisture off a part that has been applied through a series of wash/rinse nozzles.  What if the knife could apply the liquid and then a second knife could remove the liquid.  Below are some images from testing that was done on a Stainless Steel Super Air Knife at various gap sizes and various pressures.    The “best” performance visually was from operating the air knife with .004″ gap and approximately  a 17 PSIG inlet pressure (this is for a 12″ Super Air Knife).

Water flowing through a 12" Stainless Steel Super Air Knife

Water flowing through a 12″ Stainless Steel Super Air Knife

As you can see in the photos, the water does flow fairly well immediately out of the knife, and becomes more turbulent as it gets further away from the knife.   The stream actually begins to break up and thus the effective distance of the knife may be reduced when using it to flow liquids.   This is not going to perform like a pressure washer, the maximum distance for the stream of liquid before it completely fell off was around 10′ from the discharge point.   If this were to be used to remove loose debris or to cover a part in water to help cool the part the stream would be more than enough to perform.

As noted above the operating pressure was fairly low, and the gap was at a .004″ thickness.  I recently tested a 1″ Stainless Steel Super Air Wipe as well.  The shim gap was once again set to .004″ thick to permit a better flow and a low pressure, approximately 10-12 psig inlet pressure.  As you can see the flow of water is not as smooth as the air flow out of a Super Air Wipe but if a light rinsing process was needed, or a water cooling process, this would work well.

So the answer to the main question at hand is yes, a Super Air Knife and Super Air Wipe will both operate with a pressurized liquid source under the correct circumstances.   While they do not operate exactly like they do with compressed air, the results still prove useful in certain applications.
