The Blog of all Blogs: A Quick Resource of Blogs that we Blogged

EXAIR started writing Blogs in 2008. Since then, we have written well over 2000 Blogs. There is a ton of information in our Blog section on the website. There is most likely a Blog or 10 written about nearly each one of our products. These are primarily written by application engineers that know a thing or two about our products. There are also many application Blogs, that may be very relatable to what you are doing. When you journey to our Blog page (or simply click Blog form EXAIR.com), simply type in a key word or two in our search bar. This search bar is located just below the first row of published Blogs on the right hand of the screen, here is a screenshot of that section (right). You can also choose to follow our blog here as well.

As application engineers, we get asked questions every day. Many of these questions are best answered in one (or more) of these 2000+ Blogs. Many times a picture or video can answer your questions much more precisely than a quick conversation or an email. Many times we will send you a blog link to help. Drawing from my own experience, and asking the other Application Engineers for their lists, I wanted to put our most referenced blogs in one helpful location. I’ve categorized these the best that I can, and hopefully this will be a useful resource for you today, and in the future.

How Much $$$ are Compressed Air Leaks Costing You?!

All compressed air systems will have some amount of leakage. It is a good idea to set up a Leak Prevention Program.  Keeping the leakage losses to a minimum will save on compressed air generation costs, and reduce compressor operation time which can extend its life and lower maintenance costs.

The Compressed Air Challenge estimates an individual compressed air leak can cost thousands of dollars per year when using $0.07/kWh.

  • 1/16″ diameter hole in excess of $700/year
  • 1/8″ hole in excess of $2900/year
  • 1/4″ hole in excess of $11,735 per year

There are generally two types of leak prevention programs:

  • Leak Tag type programs
  • Seek-and-Repair type programs

If you walk through your facility, how many leaks can you hear? These are only the REALLY bad ones!!  So if we know that a large amount of compressed air is leaking, what do we do about it? ? A proper leak prevention plan is the key to success. Since these leaks are impossible to see and some cannot even be heard, you need a tool to help assist you. EXAIR’s model 9061 Ultrasonic Leak Detector is the right tool for the job. When compressed air leaks through a pipe, it creates an ultrasonic signature due to turbulence. While this sound is not always detectable by the human ear, this meter will allow you to locate leaks up to 20’ away by converting the ultrasonic signature into an audible sound.

The first step will be locating the leaks using an Ultrasonic Leak Detector and tagging them throughout the facility. Don’t let this overwhelm you!! If you have a larger facility, break it up into sections that can be completed in 1 day. This will allow you to decide which areas of the plant should be looked at first. Once you’ve located and tagged all of the leaks, rate them under two separate criteria so that you can prioritize what to fix first. Rate them based on the difficulty that it will take to fix them and also by the severity of the leak. Those that are severe yet easy to fix would make sense to begin fixing first. Those that may require a period of shutdown can be planned to fix at a more appropriate time.

9061 ULD

When you’ve had the opportunity to fix them, don’t just forget about it. When new piping is installed, new lines are added, or anything involving compressed air is installed there is the potential for new leaks to develop. Set this as one of your regular PM activities and complete your own compressed air audit once a year. Implementing the process and maintaining it are the keys to your success.

If you have questions about developing a leak program or how to use the Ultrasonic Leak Detector, give us a call. An Application Engineer will be happy to help with the process and recommend some other methods to save on your compressed air supply.

The Sixth Sense: Pressure Sensing Digital Flowmeters

Pressure profiles and flowrates of a compressed air system are essential parts in understanding and maintaining an industrial compressed air system. Understanding what the pressure is coming out of the compressor, what it is in your header system, and then down into the drops of your machines and points of use are all beneficial to building an efficient compressed air system. Of course, this will take some monitoring.

In a perfect system, the compressor outlet pressure and the point of use line pressure will be the same. Due to factors such as friction loss, unregulated demands (leaks), and inefficient pipe sizing, it is difficult to produce in a real life scenario. This results in a pressure drop across the compressed air system, a decline in pressure from the compressor outlet to the end use devices. Understanding the full pressure and flow layout of a system can be used to zero in on artificial demand on the system which is a result of a leaks or inefficient use of compressed air.

The Pressure Sensing Digital Flowmeters provide the ability to see both the flow on a pipe as well as the operating pressure. When coupled with other items such as our Wireless Communication network they can easily be setup to generate alerts to operators as well. This would look like a message stating that operating pressure has dropped and that would result in the operator halting production to determine the cause. While a production halt is less than desirable, a crashed machine or loss of clamping a part due to pressure drop can be worse.

Pressure Sensing Port on the Pressure Sensing Digital Flowmeter gives the added benefit of tracking more information.

By using the Pressure Sensing Digital Flowmeters you will be able to build a pressure profile throughout your system. This can all build back into an efficient compressed air system by tying directly into the information gathered for the overall system.

For instance, If a compressor set point is 90 psig, and at the point of use you are seeing 70 psig, you have a 20 psig drop in piping, fittings and/or artificial demand. If the operator needs 80 psig to maintain their process then that means someone will want to bump the compressor set point to 100 psig to compensate. First off, that pressure drop should never be present in a system as it is excessive. Second, if this is a positive displacement compressor then for every 2 psig added, the compressor itself will increase by 1% of energy demand from the drives.

If you would like to dig into your system and start building a pressure/flow profile to start off your path to an optimized system, please contact an Application Engineer.

3-1/2 EXAIR Pro Tips for Compressed Air Use

EXAIR offers industry leading Intelligent Compresses Air Products. Our products are engineered to comply with all relevant OSHA standards and are CE certified. When you purchase an EXAIR product, be it a Super Air Knife or a brass bulkhead fitting, you are expecting to receive a high quality and high performing product, and you will. If the product is not performing there is a very high probability that the problem is not the product.

So whatever could it be? And how can we fix the issue? Air supply going to the product is a common issue, so first we need to insure that there is a steady flow of the appropriate pressure and volume of air. Even though you may have a 100HP compressor, the distance form the product, the size of the pipes delivering the air, the smoothness of the inside of the pipes (is there internal rust and buildup), leaks and other restrictions of air flow rate all contribute to the overall performance.

A large majority of the product performance issues that are brought to us are caused by insufficient air supply in one form or another. Sometimes this is due to the overall size of the system, but many times it is at the point of use. Let’s assume that you have the right sized compressor to power all features in the shop. These next items are where we would want to focus and correct.

EXAIR Digital Flowmeter

Pro tip #1 – Use EXAIR Digital Flowmeters to monitor your air consumption. You should have a log of how much each compressed air tool / machine uses, and compare that to how much air is traveling down that leg of your facility. Leaks, corrosion, rust, and accidents happen. By monitoring and logging your SCFM in each major leg of your system, you will easily be able to narrow down root problems, and track leaks. You will also have solid answer when asked – “Do you have enough air for this?”.

Pressure Regulators “dial in” performance to get the job done without using more air than necessary.

Pro Tip #2 – Use a Tee Fitting and install a Pressure Regulator with Gauge at the point of use. This allows you to see, and control the pressure for each product. This removes all questions of air pressure at the point of use. Although your system seems large enough, many times the pressure is less at the point of use, due to restrictions, unknown leaks etc… Having the information from tip #1 and #2, you will easily be able to identify if your issue is the system, or the tool.

Pro Tip #2.5 – Turn it down (the pressure) if you can… Operate each compressed air application at a pressure just high enough for your desired result – not necessarily full line pressure. We have discussed in many other blogs how compressed air is your 3rd or 4th highest utility. If you optimize the pressure per application, you can save dollars. As a rule of thumb, if your system is operating at the 100 psig level, lowering the pressure by 2 psig will save 1% of energy used by the air compressor. A great example of this would be our Super Air Knives. Optimal use is at 80 psig, and “X” SCFM (based upon length of the Super Air Knife). At 80 psig and the proper SCFM, this flow will feel like having your hand out the window of your car when you are driving about 50 MPH. Your application may not need that much air flow, to get the job done. Turn it down and test it. Start at 80 psig and using the tools from tip #2, turn it up or down until your needs are met. Many of our products do not need to be used at full pressure to effectively solve your process problem.

Pro tip #3 – Use the proper sized lines, connectors and fittings. Pipe restriction can kill performance. Quick connects can be very problematic. Most quick connects are rated at the same size as the incoming pipe, tube or hose, but may actually have a much smaller inner diameter. As you can imagine, this oversight can cause significant performance issues, and end up costing more lack of production or defective product. Be it a quick connect, or any other connector or fitting, it is imperative not to restrict the air. This will result in problems, and lack of performance.

Please do not hesitate to reach to discuss any performance issues, or find out how we can help.
