You Have To Start Somewhere.

Published on by Brian FarnoLeave a comment

The school year is in full swing here in Cincinnati and all three of my daughters have different extracurricular activities they partake in. This fall, that equates to divide and conquer for my wife and me 4 nights of the week for practices then the weekends are also separate and conquer, but mainly on Saturday. This eats away at times we would typically use at home to get some walking in or even just generally getting stuff done. This schedule combined with working earlier has caused me to lose almost all workout desire. That is until I got to the first practice my oldest had which just happens to be held on my alma mater’s campus and is right next to Nippert Stadium.

When we arrived I noticed most parents were just hunkered down in their cars and watching movies or doom scrolling social media. I try to avoid doing that for 90 minutes straight if I can and so far I have. I started hitting the stairs at the University of Cincinnati’s Nippert Stadium with my 35-pound ruck on my back. While my goal is to be able to complete the standard they have for their 9/11 memorial event I also want to get back into the shape I was in when I did back-to-back GORUCK events and could crank out burpees without crying on the outside. After going up one column of stairs from the field to the concourse level I go across and down the next set until I have done every column of stairs that go from the concourse to the area directly. For their event, I have to complete two laps which will equate to the number of steps within one of the towers.

So to train, I started with seeing how many sets I could do without feeling like I was going to not be able to reach the top and walk to the car. Surprisingly, I was able to get about half of the stadium done. Then I still had another hour to kill, so I hydrated a bit and rucked on over to the track/soccer field where I could walk the track and watch co-ed intramural flag football games while I did laps. Finally, I threw in some ruck PT exercises as a cool down and ended back at the building her practice was in. When I got to work the next day I felt like I got beat with a sack of oranges from my waist down. Then, on Thursday the thought crossed my mind as I hadn’t slept much the night before to just relax, then I had a buddy ask if he could come do stairs with me, and so we did it again Thursday night.

So from now until the end of the school year, I will more than likely be rucking on or around UC’s campus and Nippert Stadium to ensure I get back into a reasonable condition without having to lose more time with my family. This isn’t always easy and doesn’t come without pain. That pain though comes with added energy and increases in my mental position as well, so I am open to more things.

The same thing can be said about an industrial compressed air system. If you just trudge through every day and don’t look at any part of your facility, it is going to cause some pain when you first start to look at it. The first step is to acknowledge that something needs to change, and you have to have that finished goal of more capacity and capability available. The best place to start on your compressed air system is at the start with mapping out the system and getting a base measurement of where you are at for consumption.. This is the first step in our 6 steps of compressed air optimization, and we can help with every step along the way, You just have to reach out to us, your accountability partner for efficient compressed air.

One Safety Air Gun, Hundreds of Possibilities

Published on by Brian FarnoLeave a comment

In case you are new to the EXAIR blog, we talk a lot about the intelligent and safe use of compressed air. Most manufacturing facilities in the world have point-of-use compressed air and that will also equal to any that do, probably have a handheld blowgun in their facility which may or may not be safe and efficient. This may very quickly be one of the most common tools used throughout some facilities and is often the most overlooked when safety and efficiency are a concern.

The Soft Grip Safety Air Gun is a versatile safety air gun from EXAIR that can easily replace most of the loud and inefficient blowguns in a facility. The option to choose from 14 different engineered air nozzles, most of which are also available in multiple materials to fit the application just right, will give the ability to fit any operator’s requirement for force and flow. Couple that with the ability to add one of 8 different extension lengths or 6 different stay set hose lengths, and it will give the operators exactly what they need for those hard-to-reach areas while staying out of harm’s way. Lastly, the chip shield adds yet another layer of protection for the users and can be adjusted up and down on the extension to fit each application’s needs.

Creating an Efficient Compressed Air System

Published on by Tyler DanielLeave a comment

The electrical costs associated with generating compressed air make it the most expensive utility in any industrial facility. In order to help offset these costs, it’s imperative that the system is operating as efficiently as possible. I’d like to take a moment to walk you through some of the ways that you can work towards making your compressed air system more efficient.

The first step you should take is to identify and fix any leaks within the distribution piping. According to the Compressed Air Challenge, up to 30% of all compressed air generated is lost through leaks. This ends up accounting for nearly 10% of your overall energy costs!! To put leaks in perspective, take a look at the graphic below from the Best Practices for Compressed Air Systems handbook.

Compressed air leaks don’t just waste energy, but they can also contribute to other operating losses. If enough air is lost through leaks, this can also cause a drop in system pressure. This can affect the functionality of other compressed air operated equipment and processes. This pressure drop can affect the efficiency of the equipment causing it to cycle on/off more frequently or to not work properly. This can lead to anything from rejected products to increased running time. With an increase in running time, there’s also the need for more frequent maintenance and unscheduled downtime.

You can perform a compressed air audit in your facility using an EXAIR Model 9061 Ultrasonic Leak Detector. If you’d prefer someone come in and do this for you, there are several companies that offer energy audit services where this will be a focal point of the process.

Speaking of maintenance, proper compressor maintenance is also critical to the overall efficiency of the system. Like all industrial equipment, a proper maintenance schedule is required in order to ensure things are operating at peak efficiency. Inadequate compressor maintenance can have a significant impact on energy consumption via lower compressor efficiency. A regular preventative maintenance schedule is required in order to keep things in good shape. The compressor, heat exchanger surfaces, lubricant, lubricant filter, air inlet filter, and dryer all need to be maintained. This can be done yourself or through a reputable compressor dealer. The costs associated with these services are outweighed in the improved reliability and performance of the compressor. A well-maintained system will not cause unexpected shutdowns and will also cost less to operate.

The manner in which you use your compressed air at the point of use should also be evaluated. Inefficient, homemade solutions are thought to be a cheap and quick solution. Unfortunately, the costs to supply these inefficient solutions with compressed air can quickly outweigh the costs of an engineered solution. An engineered compressed air nozzle such as EXAIR’s line of Super Air Nozzles are designed to utilize the coanda effect. Free, ambient air from the environment is entrained into the airflow along with the supplied compressed air. This maximizes the force and flow of the nozzle while keeping compressed air usage to a minimum.

Another method of making your compressed air system more efficient is actually quite simple: regulating the supply pressure. By installing pressure regulators at the point of use for each of your various point of use devices, you can reduce the consumption simply by reducing the pressure. This can’t be done for everything, but I’d be willing to bet that several tasks could be accomplished with the same level of efficiency at a reduced pressure. Most shop air runs at around 80-90 psig, but for general blowoff applications you can often get by operating at a lower pressure. Another simple, but often overlooked, method is to simply shut off the compressed air supply when not in use. If you haven’t yet performed an audit to identify compressed air leaks this is even more of a no-brainer. When operators go to lunch or during breaks, what’s stopping you from just simply turning a valve to shut off the supply of air? It seems simple and minute, but each step goes a long way towards reducing your overall air consumption and ultimately your energy costs.
