Understanding your ROI for EXAIR Products

Published on by EricKuhnash@EXAIR.comLeave a comment

I used to hold a purchasing/engineering role for a previous company and as part of that role I was required to understand all costs of a project. The value of knowing the return of your investment is obvious but the benefit of this knowledge enhanced communications with other team members and at times with your customer. So how can I understand the economic impact from purchasing and Intelligent Compressed Air product from EXAIR?

EXAIR makes an easier job of calculating your ROI when purchasing our product(s). Simply go to www.EXAIR.com and click on “Resources”, located on the top center of our homepage. You will see “Calculator Library” where you can see our “Air Savings Calculator“.

Calculating your ROI using this tool is simple, simply place your current consumption rate (SCFM), the cost of our product(s), the SCFM for our product(s) and your cost of compressed air per 1000 Cubic feet (if this is unknown, $0.25/1000 cubic feet is a reasonable number to use).

  1. Current Consumption (SCFM): This is the current air requirements for your current process.
  2. Cost of EXAIR Product(s): This is the expenditure of the EXAIR product(s) being purchased.
  3. EXAIR Product(s) consumption (SCFM): This can be found in our catalog, web site or by calling EXAIR and talking to an Application Engineer.
  4. Cost of Compressed Air: This can be determined at your facility or a good industry average is $0.25/1000.

The calculator will automatically calculate your return and show you the payback in number of days. EXAIR encourages the use of our website and/or calling our Application Engineers for additional information or education on air savings. We are customer friendly and always eager to help.

Quick Disconnects and Push In Fittings are not Ideal for Peak Performance

Published on by EricKuhnash@EXAIR.comLeave a comment

In order to achieve the best performance of your EXAIR Intelligent Compressed Air® product, a steady flow of compressed air must be supplied at the optimal pressure. Compressor output pressure, air flow rate, piping ID (inner diameter), the smoothness of the inside of the pipe and connector type all contribute to the performance.

Especially for manufacturing uses, it is important to consider both the air pressure and air flow being produced by the air compressor providing the supply for all tooling. It is possible for an air compressor to produce sufficient supply pressure for an EXAIR product while not having adequate air flow to use the product for very long.

The optimal air pressure for most EXAIR products is 80 PSIG, with the exception of Vortex Tube based products, which are rated at 100 PSIG. Operating EXAIR products at air pressures less than 80 PSIG may lead to lower performance, but EXAIR encourages operating any blow-off product at as low a pressure as possible to achieve your desired result. A simple pressure regulator can lower your pressure and save energy. As a general rule near the 100 PSIG level, lowering air pressure by 2 PSIG will save 1% of energy used by an air compressor. Operating the product at pressures greater than 80 PSIG may produce slightly higher performance, but will require more energy to produce only a small gain.

Make sure that connectors and fittings do not restrict compressed air flow in any manner. Quick connectors can be especially problematic in this area. Because of their construction, quick connections that are rated at the same size as the incoming pipe or hose may actually have a much smaller inner diameter than that associated pipe or hose. This will significantly restrict the amount of air that is being supplied to the tool, starving it of the air flow it needs for best performance. In some cases, if the fitting is too small, the tool may not work at all!

EXAIR products are designed to improve the overall efficiency of your operations. If you need help and have questions please contact any of the Application Engineers. There is no risk to trying our products as we have a 5 year warranty and also a 30 Day Guarantee to all of our US and Canadian customers.

Video Blog: How To Remove, or Move, A Digital Flowmeter By Using Block-off Rings

Published on by Russ BowmanLeave a comment

If you need to remove (or move) a Digital Flowmeter, EXAIR has Block-off Rings that are used to safely cover & seal the holes that were drilled in the pipe for installation. Here’s how they work:

If you’ve got any questions about Block-off Rings, Digital Flowmeters, or would like to find out more about EXAIR Corporation can help you get the most out of your compressed air system, give me a call.

Why Is Ambient Air Entrainment Needed For Pneumatic Conveyance?

Published on by Brian FarnoLeave a comment

When attempting to convey material pneumatically it can sometimes not work as one may hope. This could be due to the lack of ambient air entrainment to generate the vacuum flow which lifts the material away and moves the material. The video above gives a brief example of this.

If you would like to discuss pneumatic conveying products or processes, please contact us. EXAIR’s Line Vac air operated conveyors are a great solution for manual “bucket and ladder” applications, hopper loading, scrap conveyance, media recovery and more!
