The cost of compressed air leaks – the need to find and fix them

As margins get tighter and cost of manufacturing climbs, industries are looking for ways to be more economical.  A big focus today is in the compressed air systems.  Compressed air is considered to be the “fourth” utility behind gas, water, and electricity.  Air compressors are necessary to run pneumatic systems, but it is the least efficient of the utilities.  For every $1.00 that is put into making compressed air, you only get roughly 5¢ of work from it.  So, it is very important to use this utility as resourceful as possible. 

One of the biggest problems affecting compressed air systems are leaks.  That quiet little hissing sound from the pipe lines is costing your company much money.  For the amount of electricity required to produce compressed air, a study was conducted by a university to determine the percentage of air leaks in a typical manufacturing plant.  In a poorly maintained system, they found that 30% of the compressor capacity is lost through air leaks on average.  Majority of companies do not have a leak prevention program; so, they will fall into the “poorly maintained” category.  To put a dollar value on it, a leak that you cannot physically hear can cost you as much as $130/year.  That is just for one inaudible leak in hundreds of feet of compressed air lines.  For larger leaks, you can tell by the chart below the amount of money that can be wasted by the size of the hole.  Unlike a hydraulic system, compressed air is clean; so, leaks will not be visible at the source.  You have to find them by some other means. 

**Note 1

Most leaks occur where you have threaded fittings, connections, hoses, and pneumatic components like valves, regulators, and drains.  The Optimization products that EXAIR offers are designed to help optimize your compressed air system, and the most effective way is to find and stop leaks.  The Ultrasonic Leak Detectors can find inaudible air leaks, and the Digital Flowmeters can check your system to find leakage rates.  With both products included in a leak prevention program, you will be able to keep your compressed air system running optimally and reduce the cost caused by wasting compressed air. 

Ultrasonic Leak Detector

EXAIR Ultrasonic Leak Detector:

When a leak occurs, it emits an ultrasonic noise caused by turbulence.  These ultrasonic noises can be at a frequency above that which is audible for human hearing.  The EXAIR Ultrasonic Leak Detector can pick up these frequencies and make the leaks audible.  With three sensitivity ranges and LED display, you can find very minute leaks.  It comes with two attachments; the parabola to find leaks up to 20 feet away, and the tube attachment to define the exact location in the pipe line.  Once you find a leak, it can be marked for fixing.

EXAIR’s Digital Flowmeter w/ USB Data Logger

EXAIR Digital Flowmeter:

With the Digital Flowmeters, you can continuously watch for waste.  Air leaks can occur at any time within any section of your pneumatic area.  You can do systematic checks by isolating sections with the Digital Flowmeter and watching for a flow reading.  Another way to monitor your system would be to compare the results over time.  With the Digital Flowmeters, we have a couple of options for recording the air flow data.  We have the USB Datalogger for setting certain time increments to record the air flows.  Once the information is recorded, you can connect the USB to your computer, and with the downloadable software, you can view the information and export it into an Excel spread sheet.  We also offer a wireless capability option with the Digital Flowmeters.  You can have multiple flow meters that can communicate with your computers to continuously log and record the flow information.  Once the flow information starts trending upward for the same process, then you can use the Ultrasonic Leak Detector to find the leak.  It can also give you a preventive measure if a pneumatic system is starting to fail.

Compressed air leaks will rob you in performance, compressor life, and electrical cost.  It is important to have a leak prevention program to check for leaks periodically as they can happen at any time.  The EXAIR Ultrasonic Leak Detector and the Digital Flowmeters will help you accomplish this and optimize your compressed air system.  If you need more information, you can contact an Application Engineer at EXAIR.  Once you find and fix all your leaks, you can then focus on improving the efficiency of your blow-off devices with EXAIR products.  It will save yourself even more money.

Proper Labeling of Piping Systems Increases Safety

Industrial facilities can have a multitude of piping and utilities within them. Some of the piping can all look similar, especially if it is not labeled. water, sprinkler lines, compressed air, even steam, and refrigeration lines are just a few of those that can easily be seen within a number of manufacturing facilities. Proper labeling of these helps to ensure plant safety and can also lead to higher efficiencies within the system.

Properly labeled compressed air piping.

So how does labeling lead to safety? Well, in more than one occurrence I have been inside of facilities where piping that was not intended for compressed air, such as PVC was used for it. When the incorrect piping gets used it can become easily confused and if the contractor that is installing new equipment doesn’t do their homework then it can lead to catastrophic errors. For instance, piping can rupture, or even worse, you could easily pipe the incorrect utility into a piece of equipment. Imagine seeing PVC pipe, which is used for water, and hooking it to a rinse application only to find someone improperly used the piping for industrial compressed air. Or vise versa, an unlabeled pipe thought to be compressed air is actually city water and the next thing happening is water raining down on a packaging blowoff.

Cold Water Piping Labeled properly.

This all can and should be easily prevented by properly labeling any and all piping systems thoroughly throughout the facility. This not only names the utility but generally shows the flow direction as well which an help determine where the source is coming from as well. When performing the first step in the 6 Steps To Compressed Air Optimization knowing the direction of flow is critical when installing a Digital Flowmeter in order to assess system efficiency for compressed air.

The proper labeling and utilizing proper piping within industrial environments can easily prevent accidents and ensure ease of troubleshooting or new installations because the piping is already labeled. If you would like to discuss more on what types of piping are acceptable to use with compressed air, feel free to contact an Application Engineer.

Want to Know How Much Money you can Save? Use EXAIR’s Efficiency Lab

Growing up as a kid of the 80’s I remember wanting a Nintendo 64. This was very much a want due to the excellent advertising and having friends that got them when they first came out. So, like many kids of the times, I set forth to present my case to my parents and sell them on the benefits to me receiving this 64 bit wonder of the world. These benefits all revolved around me doing chores and “helping” to earn money to go towards the end goal. Thinking back now, I really should have started to learn more about negotiating earlier in life because my parents and older brother really made out on the deal. The point is, I had to make sure that they saw a return on their investment. Mainly, I would be entertained and they would get some stuff done around the house without complaints.

Well, flash forward to today and I still feel as though it is always an easy justification if I have supporting evidence of the benefits and even better, if there is some form of cost savings that will be had by spending money on a project or a tool. Often times the justification is the amount of time spent on a task. Well, here at EXAIR we completely embrace that justification culture and, in many cases, can provide you the information necessary to present to management or budget committee – the simple ROI your company will see when investing in EXAIR products. The best part is, this study is always free.

The way it works is pretty simple, we want to compare your current solution to our engineered products. EXAIR has a simple form that gets filled out (or you can call, e-mail or chat) explaining your application to us. We ask for a few key pieces of detailed information, and for you to send one of your current solutions (the nozzle, homemade device, or open tube for example). Then we run side by side tests in house to determine air consumption, noise, and force at the same pressure you are using at your facility. That’s right, this testing is all done here at EXAIR through our EXAIR Efficiency Lab. We document these performance characteristics and send a report showing a simple return on investment for you if you replace your device with an EXAIR engineered solution.

EXAIR’s Free Efficiency Lab

This information is then easily backed up by our 30 day guarantee on stock products. Get the EXAIR solution in, test it in your facility and see how the savings stack up. If there is anything that doesn’t stack up, you simply let us know and send the units back.

The entire Efficiency Lab and 30 day guarantee are offered to all of our customers that are within the US and Canada. If you would like to discuss what is possible for you and your team, please reach out to an Application Engineer.
