Turn Your One Bedroom Fixer-upper Compressor Room into a Pent House Suite!

Published on by Jordan T ShouseLeave a comment

First lets paint a picture, by starting with my first 400 Sq.Ft Bachelor pad in Holland Michigan. It was my first time after college living on my own and paying my own room and board! So I did what every fresh out of college 25-year-old male does, I scoured the internet for the cheapest possible living arrangements! And that was a one bedroom(ish) apartment that was one of three rentals they made from a small 1,500 Sq.ft house! It was rough, I could smell the smoke from my neighbors. I could tell what they were having for dinner by the smell and I could hear EVERYTHING! Needless to say the conditions were not the best to relax and properly live my life. (Just had a little PTSD thinking about it)

Yeah, that was a problem too……… (Longest 6 months of my Life)

I said all of that just to say the Environment Matters! For me, it was my living conditions and I learned that the hard way! But for your Air compressor it’s the compressor room in which it sits! While we don’t sell compressors, pretty much all of our products use compressed air so helping you generate and use it in the best and most efficient way is important to us!

Some of the mistakes that are commonly made in the compressor room are by design, and others are operational. Let’s cover a few;

  • 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). Add in all that friction, and you come up with a TREMENDOUS amount of heat. An industry rule of thumb, 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. Many compressors also have optional heat recovery systems as well.
  • 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.
  • 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.

Don’t put your compressor in a room that smells like a cigarette butt covered in cooking grease that is infested with cockroaches. Set it up in the pent house, and it will reward you with dependable and efficient operation for a very long time!

Intelligent Compressed Air®: Common Compressor Room Mistakes, And How To Avoid Them

Published on by Russ BowmanLeave a comment

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.

How to Save Money on Compressed Air

Published on by codybiehleLeave a comment

Compressed air can be one of the more expensive utilities to use in a facility, but a compressed air system is full of simple opportunities to increase efficiency and minimize the cost. Much like how you can take multiple steps to save electricity at your house there a few simple steps you can take to save your compressed air. These steps include finding and repairing leaks, compressor maintenance, minimizing pressure at the point of use, and turning the compressed air off when not in use. Implementing these steps and using the right tools to achieve them can lead to significant dollar savings – in fact our website case studies, other blog articles and catalog are filled with example after example of air (and dollar) savings success! And let’s be honest here, who doesn’t like saving money.

First off is finding your leaks. Leaks are one of the major wastes of compressed air in a system that could happen. Leaks in a compressed air system can account for wasting 20-30% of a compressors output. These leaks can commonly be found in pipe joints, devices that use the compressed air, quick connect fittings, and storage tanks. All of this compounds to wasting air much like a leaky faucet wastes water – little by little it grows until it simply needs to be addressed. One of the ways to help find leaks in your system is EXAIR’s affordable Ultrasonic Leak Detector. This leak detector uses ultrasonic waves to detect where costly leaks can be found so that they can be patched or fixed.

EXAIR Ultrasonic Leak Detector

Choose efficient end-use products. Engineered air knives, air amplifiers, air nozzles and safety air guns can dramatically outperform (use less air) than commercial air nozzles and in-house solutions such as drilled pipes, open air lines and other creative “fixes”. We have seen some very nice in-house solutions from customers who have put in some significant time and effort, but they all have one thing in common – they use more air than any of EXAIR’s engineered solutions.

Minimizing your pressure can also save you money by limiting the amount of compressed air that is being used. Pressure and volume go hand and hand, the higher the pressure the higher the volume of air and vice versa. By minimizing the pressure that you are using you are also minimizing the amount of air that is being used which means savings. Each CFM used can be associated with a certain price value so the less you use the more you save. You also cut down on the amount of work the compressor has to do and how often the compressor has to cycle. Pressure can be minimized using one of EXAIR’s Pressure Regulators to cut down on the amount of air being used.

EXAIR’s Pressure Regulators come in 4 different sizes

Turn off the compressed air when it is not in use. Just like how you wouldn’t leave the faucet running or lights on in a room that is not being used, don’t leave your compressed air running (insert bad dad joke). Constantly using compressed air even when not in use will cause the compressor to cycle more often wasting money. Each CFM has a price to it so don’t waste CFM’s blowing it back into the air and doing nothing. This can simply be done by adding one of EXAIR’s ball valve or solenoid valves to turn off when you are done using it. Also, if you want to take it another step farther you can look at using one of EXAIR’s Electronic Flow Controllers (EFC). The EFC uses a photo eye attached to a timer that will open a solenoid valve for a set amount of time when it detects an object within 3’ of the photo eye. This will turn the air on only when your product is in the air path and turn it off during any spaces in between.

Compressor maintenance is another important step to minimizing the cost of compressed air. Neglected air compressors can cause a lot of issues ranging from expensive repairs to a decreases in efficiency. Wear and tear placed on the motor of an air compressor can cause the compressor to produce less compressed air (SCFM) at the same power consumption. This means you are paying the same amount of money and getting less out of it. Making sure that your compressor or any machine is always running at its optimal performance and should always be a priority for any facility.

There are many different ways to save on compressed air, these are just a few of them. Reducing air use will save money and reduce the demand on your compressor which in turn can prolong the life of your air compressor.

Compressed Air Leaks and the Problems They Cause

Published on by codybiehleLeave a comment

Over the Fourth of July I had a great opportunity to do some backpacking in the backwoods of the Adirondack Mountains in Upstate New York. “That sounds awesome!” is what most people would think; looking back on it, it was awesome. BUT, at the time it was the very definition of complete and total suffer fest. During my time on the trail, I learned three life lessons. First, always thoroughly study up on every bail out point along the trail. Second, water proofing has its limits; and thirdly, when things leak it is dreadful. After 7 miles of crawling over rocks and traversing lakes and streams in the pouring down rain everything was soaked and water was leaking through our rain jackets, leaving me and my girlfriend cold, wet, and sore as all get out – all on day one.

Heading up the Algonquin Mountain trail starting Colden Lake

Leaks don’t just stink when they appear in your rain coat, they are dreadful all around whether it is leaking faucets, a leaky basement or compressed air line leaks. Unlike the fact that I currently have no solution for the leaking rain coat, I do have a solution for your leaking air lines. Leaks are costly and an all-around waste of money that can have severe implications on how the air is being used and the entire system itself.

There are four main affects that a leak in your compressed air system can have and they are as follows; 1) leaks can cause a pressure drop across the system, 2) leaks shorten the life of almost all air supply system equipment, 3) leaks demand increased running time of the compressor, and 4) leaks produce unnecessary compressor capacity by demanding more and more air.

  • A pressure drop across your compressed air system can lead to a decreased efficiency of the end use equipment (i.e. an EXAIR Air Knife or Air Nozzle). This adversely effects production as it may take longer to blow off or cool a product or not blow off the product well enough to meet quality standards.
  • Leaks can shorten the life of almost all supply system components such as air compressors. This is because the compressor has to continuously run to make up for the air lost from leaks. By forcing the equipment to continuously run or cycle more frequently means that the moving parts in the compressor will wear down faster.
  • An increased run time due to leaks can also lead to more maintenance on supply equipment for the same reasons as to why the life of the compressor is shortened. The increase stress on the compressor and supply side components due to unnecessary running of the compressor.
  • Leaks can also lead to adding unnecessary compressor size. The wasted air that is being expelled from the leak is an additional demand in your system. If leaks are not fixed it may require a larger compressor to make up for the loss of air in your system.
EXAIR’s Ultrasonic Leak Detector

It is fairly easy to find these leaks, simply use EXAIR’s affordable Ultrasonic Leak Detector. This leak detector uses ultrasonic waves to detect where costly leaks can be found so that they can be patched or fixed. So don’t get stuck in some rainy day with your compressed air leaking everywhere; find those pesky leaks, mark them for maintenance and seal them up.

If you have any questions or want more information on EXAIR’s Ultrasonic Leak Detector or like products. Give us a call, we have a team of application engineers ready to answer your questions and recommend a solution for your applications.
