Calculate the Value of Your Compressed Air Savings

Published on by Kirk EdwardsLeave a comment

Most everybody wants to know how much compressed air they can save when they use EXAIR products and how much money that air savings will equal. I will explain how to calculate air savings and dollars saved, hopefully with better results than this…

The basic formula for savings per hour is this:
 [ X – Y] x Comp$ x T = Saved Air Value
     With:
      X – Existing Air Consumption
      Y – EXAIR Product Consumption
Comp$ – Cost of Compressed Air per 1000 Standard Cubic Feet (SCF)
T – Time Frame of 60 Minutes
Saved Air – Air Savings in Dollars per Hour

To determine your existing air consumption you should
1. Measure your compressed air flow with a flow meter on the specific supply leg of your system.
2. Provide details about your compressed air system using the EXAIR Efficiency Lab and we will        measure or estimate your current consumption.

To determine the consumption of the EXAIR product(s), use the air consumption information provided in our catalog or website. If you would like assistance determining air consumption at a pressure other than 80 PSIG (standard pressure in the catalog or web), please contact us.

If you don’t know your actual cost of compressed air per 1000 Standard Cubic Feet (SCF), a reasonable average to use is $0.25 per 1000 SCF.

EXAMPLE: Drilled Pipe vs. Super Air Knife @ 80 PSIG
[ X – Y] x Comp$ x T = Saved Air Value

18″ drilled pipe w/ 1/16″ holes every 1/2″ (37 holes) = 140.6 SCFM (standard cubic feet per minute)
18″ Super Air Knife = 52 SCFM

[140.6 – 52.2] x [0.25/1000] x 60
88.4 x .00025 x 60
.022 x 60
= $1.33 saved per hour

Once you have the value of saved air per hour ($1.33 in this example) you can determine dollars saved per week and year depending on your schedule.
40 hour work week = $53.20 saved per week
52 weeks per year = $2766.40 saved per year 

Not bad results for a $300.00 investment! You can see additional details about this example HERE. And for an automatic calculator which shows dollar savings and return on investment calculations CLICK HERE.

Sucessful Business as Light Bulb Changer

Published on by Leave a comment

America is truly the land of opportunity if you are willing to go for it. Recently I talked with a customer who was out of work and doing odd jobs for his church. One job he found particularly challenging was changing the flood lamps in a 30 foot ceiling. The conventional method is to erect scaffolding and climb up to the bulbs. 

Thinking outside the box he found that there were suction cups on the end of poles used for this purpose. What he found though, is that dust and grime collected on the surfaces over time, compromised the vacuum and they would drop the bulb bursting onto the floor.

Tenacious as he is, he did a web search for vacuum and came across EXAIR and that is how we met. I told him the problem with the push to vacuum cups is that they have no way to regenerate any leakage and that is why his bulbs were falling off.

 I suggested using our model 840008 E-Vac with a 6″ suction cup model 900761 . The suction cup was mounted on the end 30′ tube with an air line going down the center of it to an E-Vac at the other end. The E-vac maintained a consistent vacuum despite any leakage and the problem of broken light bulbs went away.

His Pastor suggested that other churches could use the services of his new invention and that was the beginning of new employment for him and another EXAIR success story.

If you have a challenge that you think one of EXAIR’s products could help you, feel free to contact me. I will be happy to go through it with you.

EXAIR Super Air Knife Prevents Rejects and Press Damage.

Published on by Kirk EdwardsLeave a comment

We have a customer who produces automotive stampings and assemblies. Within their process they have a welding cell which places a weld nut on to the stamping.

Within the cell an M6 nut is placed on the stamping and held in place with a magnet. An automated vision inspection is done to determine if the nut has been placed on the stamping. If all things are OK, the nut is welded to the stamping and it moves into a punch press for further modification.

If the vision inspection does not see the nut, another one is placed on to the stamping. The problem is the magnet is strong enough to hold a misplaced nut as well and when another nut is placed on to the stamping there is the potential for the misplaced nut to still be on the stamping. A misplaced nut moving into the next step of the punch process will damage the punch and the product.

EXAIR supplied a 6″ Super Air Knife to provide a blast of air over a wide area after the weld process and the magnet has been removed. This 6″ wide area blast of air makes sure that the entire area a misplaced nut could be is blown clear, removing any chance that a nut will damage the punch or the product.

This is a case where a simple, low-cost solution prevents a complicated and expensive problem.
