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.
OPTIMIZING YOUR COMPRESSED AIR SYSTEM
This is one of the key sections to our blogs. One of our main goals is to help you optimize your system. Here are 6 blogs that go into detail on each of these key points:
This is a product line that has a lot of maintenance questions, probably because these products are used to clean up dirt, and where there is dirt, there can be problems, clogs and leaks:
One of the most common questions we have concerns the Reversible Drum Vacuum (RDV) refurbishment Blog. The RDV is used on the Reversible Drum Vac, and the Chip Trapper products. We offer a refurb service for a fee, but most of the time you can do this on your own by watching and following this blog: Cleaning the Reversible Drum Vac
There are many more blogs and videos at your disposal. This is just a recap of many of our most used, most viewed and most helpful for the day-to-day conversations that happen here at EXAIR. If you have ideas for new blogs – we would love to hear that as well. Please feel free to reach out at any time for more information on any of our intelligent compressed air products.

With energy bills skyrocketing, it becomes critical to stop the waste. Air leaks are a constant part of any compressed air system. If you do not own an Ultrasonic Leak Detector, you are throwing money away. As air lines age, leaks happen. Rust erodes the pipes. Curves, twists and turns lead to weak joints. Fittings (especially push-in fittings) and other pipe connections will degrade and begin to leak. Day-to-day wear and tear, bumps and bruises will all cause small air leaks over time. Having an air leak in your system is similar to having a running toilet in your home. You won’t see any visible damage, but when you get that utility bill!
It can be difficult to find the leaks in a large facility. The air lines could run a long way, with multiple twists and turns within your system. The area can be loud, and leaks can be very quiet… Of course the large leaks are easy to identify, see, hear and feel. But many leaks are very small, hard to locate and the noise form these leaks can be “Ultrasonic sound”, meaning that they are at a frequency between 20kHz and 100kHz, and cannot be heard by the human ear. To find these small leaks and to hear Ultrasonic sounds, you will need an Ultrasonic Leak Detector.
With this precision tool, you will be able to both hear and see where the leaks are. As you pass the Detector across the pipes the alarm lights will glow and grow, and if you have the noise canceling headphones on, you will also be able to hear the leak.
Here is an example of how costly 1 small 1/16th” leak can be:

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.
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.
While we don’t sell, install, or service air compressors, EXAIR Intelligent Compressed Air Products run on compressed air, so helping you get the most out of your compressed air system is important to us. Today, we’re starting where it all begins: the compressor room.
Some of the mistakes that are commonly made in the compressor room are by design, and others are operational. My colleague Tyler Daniel wrote a great blog on design considerations recently, so I’m going to focus on the operational aspects, which include maintenance…and maybe some minor design stuff:
Poor ventilation: Air compressors get hot. They’ve got a lot of moving parts, and many of those parts are moving under a great amount of force (pressure is literally defined as force per unit area), and at a high rate of speed. Add in the heat of compression (it takes energy to compress air, and that energy has to go somewhere, something another colleague, John Ball, explains here), to all that friction and you come up with a TREMENDOUS amount of heat. An industry thumbrule, in fact, states that over 2500 Btu/hr of heat is generated, PER HORSEPOWER, by a typical industrial air compressor. If the compressor room isn’t big enough, you’ll need an exhaust fan capable of removing all that heat.
Lack of filtration: Take a good, full breath in through your nose, right now. Did you smell anything unpleasant or irritating? I hope not…clean air is a “must” for your lungs (and the rest of your body), and the same is true for your air compressor (and the rest of your compressed air system). Keeping up with the maintenance on the intake filter is literally “starting where it all begins”…from the 1st paragraph.
Not removing moisture: Water & water vapor will have an adverse effect on many components of your compressed air system: it’ll cause rust in iron pipes, damage the seals in air cylinders, motors, tools, etc., and if you use it for blow off or conveying, it’ll contaminate your product. We’ve written…again and again…about the importance of dryers, and which type might be best for you.
Tolerating leaks: The compressor room is loud, so leaks are going to be pretty big before you can hear them. And to add insult to injury, the vibration of a running compressor makes the compressor room a prime location for them to occur. Even one small leak that you couldn’t hear in a quieter area will cost you over $100 over the course of the year, and maybe only take minutes to fix. Good news is, even if you can’t hear them, they ALL make an ultrasonic signature, and we’ve got something for that.
Ignoring maintenance. If you don’t schedule planned maintenance, your equipment will schedule corrective maintenance for you…oftentimes at greater expense, and with no regard to your schedule.
Moving metal parts that make metal-to-metal contact (or that have very tight spacing tolerances) HAVE to be lubricated properly. If you run low on oil, or let it get dirty or emulsified, severe damage will follow. Keeping an eye on the oil level, and changing it (and the filter) at the manufacturer’s recommended intervals, is critical.
Emulsified or otherwise contaminated oil can damage seals, gaskets, and o-rings. That’s obviously a big problem for the compressor, and when it carries over into the header, it’s a big problem for pneumatic cylinders & tools as well. Periodic sampling & analysis of your oil can provide timely notice of issues that can be corrected before they become catastrophic failures.
Depending on the type of compressor, and its drive system, the manufacturer’s maintenance recommendations may also include:
Checking coupling or belt alignment of the drive.
Checking bolts for loosening due to vibration (a “necessary evil”, especially with reciprocating compressors).
Adjusting the pistons to maintain valve plate clearance.
Tightening or replacing the mounts & vibration pads.
