Video Blog: EXAIR Efficiency Lab

The video below is a brief introduction to the EXAIR Efficiency Lab, a free service provided by EXAIR for customers within the USA and Canada.

If you have a single point blowoff that does not have an engineered nozzle, or if you have a wider format blowoff, manifold or home-made drilled pipe, contact an Application Engineer with EXAIR and let us help you to reduce your energy waste. Following are some examples of product where we have helped to save some serious air and reduced noise levels which heightens employee comfort.

Pressure Profile: Where to Measure Your Air Pressure

Generic Layout drawing of compressed air piping system.

In order to fully understand how efficient your compressed air system may be, you will need to generate a system pressure profile at some point.   This is a list or diagram of what pressures you have in your compressed air system at specific locations, as well as the pressure required by all the demand devices on your compressed air system.

One of the reasons for the pressure profile is that you may have an application that is far away from the compressor but also highly dependent on a specific operating pressure.   You may also find an application that, due to pressure losses within the system, causes an artificially high pressure demand.

The list below gives the critical points for measuring your compressed air system profile.

  1. At the air compressor discharge. (If using multiple compressors, measure at each.)
  2. If dryers of any type are being used after the compressor measure downstream from the dryer.
  3. Downstream of each filter. (If a particulate filter and oil removal filter are being used it is best to measure downstream of each individual device.   This is to tell when you have more than a 5 psig pressure drop or a clogged filter.)
  4. After each intermediate storage device, such as receiver tanks.
  5. At the point just before the main line from your compressor room branches off to distribution.
  6. The furthest point of each header line you have installed.
  7. On both sides of every filter/regulator units that are at high pressure point of use applications.

To give you an idea of why it is so important to measure these locations, take a look at the blogs we have posted on pressure drop. (Link Here)  As you can tell by the list of blogs that comes up, pressure drop through piping can really cause a lot of wasted energy in your compressed air system.   If you can get a good base line measurement by utilizing a pressure profile then you can start the process to optimizing your compressed air system.

Back To The Basics (of compressed air)…And The Track

The past several weeks I have been finding myself doing things the more complicated way (I  know how that sounds odd – an engineer that prefers to do things the hard way). Over the weekend I took a brief ride on the motorcycle for a short 15 minute trip that I found to be satisfying, even if it is less direct and a more out-of-the-way route for getting my errands complete.   The route runs past the local university of Mount Saint Joseph, down a winding road that has no houses and only one business, the rest is all woods and a creek.  Finally, this route runs along the mighty Ohio river and back up a steep winding road near my house.

While I have been worrying about all the projects and errands which need to be completed, this more complicated route gives me a moment to decompress and remember that my family at home and few other things are all I need.  Once  I was reminded of that and got some perspective which allowed me to “keep calm and carry on” I proceeded to break my projects and errands down into smaller pieces and everything will start to come together.

I now have a to do list at home as well as a refreshed list at EXAIR of all the items I need to do.   The list at home is considerably more fun as it all involves getting my “new to me” track bike ready for this season.  20140506_134512That’s right, it’s right around the corner, the first track weekend of 2014.  So expect to see some more motorcycle blogs coming and hopefully more ways to use EXAIR products while working on them. It was these newly developed lists that helped me reorganize and get back on track for the new season, sometimes a list is necessary in order to gain perspective, prioritize and begin to take action.

On that note, EXAIR has a list to help you gain perspective, prioritize and take some action toward getting your compressed air system optimized. Our systematic approach using the Six Steps To Compressed Air Optimization has been developed to help you save your compressed air,your hearing, and your money. By following these steps you can lower your compressed air use, minimize workplace noise exposure (OSHA will be happy) and save money on this important utility.

If you have ever thought of reducing your compressed air costs, use our list to help you gain perspective on this simple process and take some positive steps toward saving your facility some money.

Compressed Air and Halloween Candy

Tomorrow night is Halloween. I live in a suburban subdivision with a high ratio of young families, which makes for a target-rich environment for Trick or Treaters…my boys included. We’ll allow them to enjoy a sensible portion of their haul tomorrow night, and the rest will go into the cabinet over the stove for rationing out over the next week or so.

First to disappear will be the brand name chocolates, candy bars, peanut butter cups, etc. The occasional bags of pretzels/salty snacks will find their way into school lunch bags quickly. Novelty lollipops – the kind with candy or gum in the middle – go fast in my house, but only after the chocolate has been completely exhausted. Individual hard candies linger at the bottom until they’re forgotten about, and eventually get thrown away the next time we need one of those pans we keep in that cabinet…usually when we’re preparing Thanksgiving dinner.

One of the trade publications I read regularly is “Compressed Air Best Practices” Magazine. Every month, there are featured articles that highlight how someone just saved a TON of compressed air by applying various methods and fixes to their systems. Understandably, the opportunities for the largest savings are the most popular…let’s call these the “brand name chocolates.” Common examples of this are:

  • Fixing leaks – I know of a company that saved a million SCF per year this way. (Spoiler alert: it was us.)
  • Replacing open ended blow offs with engineered products. (Spoiler alert again: we’re the undisputed industry leader for this.)

Of course, you can’t manage what you can’t measure. If you’re serious about efficiency, you’ve already got flow meters in place. If not, it’s time for a look at what’s available, and how much of a benefit you’ll get from knowing what your usage is at any given time. Continuing with my candy surplus analogy, these could be considered the novelty lollipops. Departing from the analogy, though, this should be done first (OK; it’s not a perfect analogy). An EXAIR Digital Flowmeter will give you instant, accurate indication of your air usage, and you can make a “before/after” comparison, once those leaks are fixed and your blow offs are upgraded.

Lastly, don’t forget about regular maintenance. Our USB Data Logger is a great addition to the Digital Flowmeter – it allows you to track your usage over time. Those leaks you just fixed weren’t there when the system was new. If you start to see your usage creeping up, you’ll want to find out why. Our Ultrasonic Leak Detector is a great tool for periodic checks. Use it to find any new leaks that pop up, and you’ll stop throwing away compressed air like it was candy.
