## Replacing a 1/4″ Open Copper Tube With a 2″ Flat Super Air Nozzle Leads To Quick ROI

The generation of compressed air accounts for approximately 1/3 of all energy costs in an industrial facility and up to 30% of that compressed air is wasted through inefficient operation. Open pipes or homemade blowoffs waste a ton of compressed air, resulting in high operating costs. By replacing these devices with an energy efficient, engineered solution, you can reduce this waste and dramatically cut energy costs.

For example, let’s look at the average operating costs for a single 1/4″ open copper tube. (If you don’t know you current energy costs, a reasonable average to use is \$ 0.25 per every 1,000 SCF used, based on \$ 0.08/kWh.

A single 1/4″ open copper tube consumes 33 SCFM @ 80 PSIG and costs roughly \$ 0.50 per hour to operate. (33 SCF x 60 minutes x \$ 0.25 / 1,000 = \$ 0.50). For an 8 hour shift, the total cost would be \$ 4.00 (\$ 0.50 x 8 hours = \$ 4.00).

If we were to replace the 1/4″ open copper tube with our Model # 1122 2″ Flat Super Air Nozzle with 1/4″ FNPT inlet, the air consumption would be reduced to 21.8 SCFM @ 80 PSIG. This may not seem like much of an air usage reduction, but when you look at the monetary, total cost of ownership for purchasing and operating the nozzle, the savings can quickly add up.

The operating cost for a 2″ Flat Super Air Nozzle with 1/4″ FNPT inlet is \$ 0.33 per hour (21.8 SCF x 60 minutes x \$ 0.25 / 1,000 = \$ .033) or \$ 2.64 per 8 hour shift (\$ 0.33 x 8 hours = \$ 2.64).

We can now compare the operational cost between the 2 devices:

1/4″ open copper tube operating costs:
\$ 0.50 per hour
\$ 4.00 per day (8 hours)

2″ Flat Super Air Nozzle operating costs:
\$ 0.33 per hour
\$ 2.64 per day (8 hours)

Cost Savings:
\$ 4.00 / day (open copper tube) –  \$ 2.64 / day (2″ Flat Super Air Nozzle) = \$ 1.36 savings per day

The Model # 1122 2″ Flat Super Air Nozzle has a list price \$ 67.00 USD.

ROI or Return On Investment calculation:
\$ 67.00 (Cost) / \$ 1.36 (savings per day) = 49.26 days.

The 2″ Flat Super Air Nozzle would pay for itself in just over 49 days in operation. This is the savings for replacing just ONE 1/4″ open copper tube with an engineered solution! In most industrial plants, there could be several of these which presents even more opportunities to reduce the overall operational costs.

Our focus here at EXAIR is to improve the overall efficiency of industrial compressed air operating processes and point of use compressed air operated products. If you are looking to reduce compressed air usage in your facility, contact an application engineer and let us help you optimize your current system.
