EXAIR’s 1″ Flat Super Air Nozzles Provide Fast ROI When Replacing Inefficient Blowoffs

Any time you’re considering a new purchase your return on investment is a critical aspect of the decision-making process. An easy way to illustrate this is the use of an LED lightbulb. An LED lightbulb may cost more initially but will use less energy to operate. In addition, it’ll also have a longer lifespan than an incandescent bulb. You can calculate, down to the day, when you’ll recoup the costs difference from buying the more expensive bulb.

The same can be said for EXAIR’s Intelligent Compressed Air Products. In many cases, our products are replacing a homemade, cheap, or otherwise inefficient blowoff device. Let’s walk through an example of an application where EXAIR helped save a company money by reducing their compressed air consumption.

An extrusion company had a line where they were using (3) modular-hose style flat nozzles. These products are not designed to be used with compressed air, but rather are intended for distributing liquid coolant. Despite these devices not being designed for compressed air, seeing them used for blowoff purposes is all to common in industrial applications. A total of (3) nozzles were being used to dry the material as it exited a cooling bath. While they did work for them in the application, they had begun to notice pressure drops in their compressed air system that was causing issues for other processes in the facility.

The (3) nozzles were all operated at 50 PSIG consuming 17 SCFM per nozzle for a total consumption of 51 SCFM. They were operated for one full 8-hour shift, 5 days per week.

51 SCFM x 60 mins x 8-hours = 24,480 SCF/day

To keep the same airflow profile, we recommended the Model 1126 1” Flat Super Air Nozzle to replace the modular hose. Operating at 50 PSIG, the 1126 will consume 7.17 SCFM of compressed air. With a total of (3) nozzles operating, that comes to 21.5 SCFM total for the drying operation.

21.5 SCFM x 60 mins x 8-hours = 10,320 SCF/day

By implementing the 1” Flat Super Air Nozzles, they reduced their compressed air consumption for this particular application by 57%!! But, just how quickly will that air savings provide them with a return on their investment? Let’s calculate the savings:

The average cost for compressed air is $0.25/1000 SCF. Before the installation of the Super Air Knives, the total consumption was 24,480 SCF/day.

24,480 SCF x $0.25/1000 SCF = $6.12/ day

With the Flat Super Air Nozzles, this was reduced to just 10,320 SCF/ day:

10,320 SCF x $0.25/1000 SCF = $2.58/ day

Total Savings – $3.54 each day!!!

The 2022 list price on the Model 1126 is $53.00. Since they bought (3) their total investment was $159.00.

$159.00/$3.54 = 44.92 (45 days)

On the 45th day, the customer will have saved enough money from the reduced air consumption to account for the initial purchase price of the Flat Super Air Nozzles. Once they’re paid for, it isn’t like you just stop saving money. The nozzles will continue to save money, each shift, day in and day out. In some areas, your local utility provider may also offer rebates for the installation of engineered compressed air nozzles when replacing an inefficient solution.

If there’s a process in your facility that you can improve upon, give us a call. We’re also able to test it out here at EXAIR and report back to you on the savings through our free Efficiency Lab!
