Leaks and Their Impact on Your Compressed Air System

Leaks are one of the major wastes of compressed air that could happen in a system. But what affect can leaks have on your system and how can these leaks be found? Total leaks in a compressed air line can account for wasting almost 20-30% of a compressors output. These leaks can commonly be found in areas were a pipe comes in contact with a joint, connections to devices that use the compressed air, and storage tanks.

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

  • A pressure drop across your compressed air system can lead to a decreased in 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 loss from the leak. 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 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

All of these effects are an additional cost that is tacked onto the already existing utility cost of your compressed air. But luckily there are ways to find these leaks and patch them up before it can get to out of control. One of the ways to help find leaks in your system is the EXAIR’s affordable Ultrasonic Leak Detector. This leak detector uses ultrasonic waves to detect were costly leaks can be found so that they can be patched or fixed.

If you have questions about a Leak Prevention Program or any of the 16 different EXAIR Intelligent Compressed Air® Product lines, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

EXAIR Provides you with the Necessary Tools for Training

I recently participated in a spicy wing eating competition here in Cincinnati. A last-man-standing format where contestants were tasked with finishing a single wing in 30 seconds per round. As the rounds increased, so too did the heat level of the sauce the wing was tossed in. The GRAND PRIZE for the daring winner was quite a haul, a $50 gift card to a local wing joint. Why put yourself through this for the chance at winning a $50 gift card I was repeatedly asked. Who knows, maybe I’m crazy. But, anyone who knows me knows I love a good competition and I wasn’t going to go into this one unprepared. Training for the competition was going to be necessary if I wanted to stand a chance.

Peach Reaper Peppers – The Breakfast of Champions

Several weeks of putting myself through a hellacious bout of pain, misery, and indigestion by way of Ghost Peppers, Trinidad Scorpion Peppers, and Peach Reaper peppers from my garden, I felt like I was ready to go. I started off the morning of the competition with some Peach Reapers in my breakfast burrito (the hottest I had on hand). Through the sweat, tears, and pain (along with a few eye rolls from my wife) I felt as prepared as I could possibly be. Unfortunately, all of my training didn’t quite get me the win. But, a respectable 2nd place finish wasn’t a bad showing. I suppose I’ll have to step my game up for next year…

Happy Independence Day From EXAIR!

flag bald eagle
Please Note: EXAIR will be closed July 4th in observation of the United States Independence Day

Summer is my favorite time of year. Warm weather, hanging out by the pool, and enjoying the outdoors (weather permitting of course). It’s also the time of year when my favorite holiday occurs, Independence Day. EXAIR will be closed on July 4th in celebration of Independence Day. On this day 243 years ago the Declaration of Independence was adopted, marking the official legal separation of the Thirteen Colonies from Great Britain.

Although today we celebrate on July 4th, Congress actually voted to declare independence two days earlier on July 2nd. If it were up to John Adams, that would be the date we commemorate to this day. He wrote in a letter to his wife that this would be the most memorable day in the history of America, to be celebrated by pomp and parade, games, sports, guns, bells, bonfires, and illuminations from one end of this continent to the other. In protest of July 4th being designated a federal holiday, he was reported to turn down invitations to appear. Coincidentally, both he and Thomas Jefferson both passed away on July 4, 1829 on the 50th anniversary of the adoption of the Declaration of Independence.

I imagine the celebrations looked quite a bit different back then, but today many of us will spend time with our family and friends enjoying some BBQ. Parades and firework shows are also in abundance as we celebrate together as a country in unison.

“America was not built on fear. America was built on courage, on imagination and an unbeatable determination to do the job at hand.” – Harry S. Truman

The very same can be said of EXAIR, built on the courage, imagination and determination of our late founder Roy Sweeney. Without his willingness to take risks and build his version of the American Dream, we would have never come to be.

So while we celebrate, hot dog in hand, take a moment to reflect on what it means to be an American. Enjoy your right to life, liberty, and the pursuit of happiness. To all of my fellow Americans on behalf of EXAIR, Happy Birthday to US!

EXAIR Intelligent Compressed Air Products Are Automation’s Best Friend

For decades, children and adults (really cool ones, anyway) have enjoyed the popular board game, Mouse Trap:

The fun of the game is that it exaggerates the notion of providing an overly complicated solution to a simple problem – a notion made famous by Rube Goldberg, whose namesake machines are as thought-provoking as they are entertaining to watch.

As fun as Rube Goldberg machines are, there are actually ways to engineer something “just enough” – that’s what automation engineers strive to do every day; and EXAIR is here to help.

Probably the most popular feature, for automated applications, of engineered compressed air products is instantaneous performance.  For example:

  • When an electric motor-powered blower is used for a blow off, cooling, or drying application, there’s going to be a “ramp-up” period to reach full rated flow.  Not so with an EXAIR Intelligent Compressed Air Product, like a Super Air Wipe, Super Air Knife, Super Air Nozzle, Super Air Amplifier, etc.  They are generating their rated flow as fast as you can open the supply valve.

    EXAIR Intelligent Compressed Air Products such as (left to right) the Super Air Wipe, Super Air Knife, Super Air Nozzle, and Super Air Amplifier provide instant on/off performance, at rated levels.
  • Likewise, vacuum pumps necessarily take some time to develop their rated vacuum level.  But the venturi in an EXAIR E-Vac Vacuum Generator draws its full rated vacuum flow as soon as the compressed air is turned on.  The peak vacuum level is achieved in the amount of time it takes to pull the air out of the lines or vessel.

    These are all examples of how an E-Vac pick-and-place system is just a solenoid valve away from being an automated process.
  • All EXAIR Atomizing Spray Nozzles can be fitted with a No Drip feature, which allows instant on/off control, simply by opening/closing a valve in the compressed air supply line.  This is often done with a solenoid valve tied in to the machine controls, or with an EXAIR EFC, Electronic Flow Control (more on that in a minute.)  They can handle up to 180 cycles per minute, for quick bursts of atomized mist, on demand.  No other method of liquid flow control can match that kind of performance.

    Fine mist liquid spray, on demand, from an EXAIR No Drip Atomizing Spray Nozzle.
  • EXAIR Spot Cooling Products, Cold Guns, and Cabinet Cooler Systems all use Vortex Tube technology.  This “splits” a supply of compressed air into a hot, and cold air flow.  Unlike refrigerant, chilled water, or cryogenic gas methods, they don’t rely on conduction or convection heat transfer between materials, so cold (and hot) air is produced, at rated flow and temperature, instantly.  They, too, can be turned on & off as often as needed…there are no moving parts to wear or damage.

    The unique phenomenon of the Vortex Tube principle makes cold air instantly for as long – or short – a time as needed.

Automation projects often incorporate existing logic, controls, timers, etc. to actuate the process.  For example, if you wanted to use a Chip Vac to vacuum debris from a chop saw, you can simply wire a solenoid valve into the power switch of the saw…it’ll run while the saw runs, and stop when the saw is turned off.

EXAIR’s award winning EFC Electronic Flow is ready to go, right out of the box.

If there are no existing logic, controls, timers, etc., EXAIR has a solution for those cases too: the EFC Electronic Flow Control.  We have four models to accommodate up to 350 SCFM of compressed air flow – that’s ten feet worth of Super Air Knives.  The EFC consists of a photoelectric sensor that opens/closes a solenoid valve, based on the programming of the integral timer.  It’s a stand alone system that doesn’t require input from, nor is it affected by, any external factors.

Automation projects can get pretty intricate.  EXAIR Intelligent Compressed Air Products are aimed at keeping their involvement as simple as possible.  If you’d like to find out more, give me a call.

316 Stainless Steel Products- Always in Stock

Metallurgically speaking, stainless steel is a steel alloy with the highest percentage contents of iron, chromium and nickel, with a minimum of 10.5% chromium content by mass, and a maximum of 1.2% of carbon by mass.

Stainless steels are widely regarded for the corrosion resistance that they exhibit. As the chromium content is raised, the corrosion resistance increases as well. The addition of molybdenum also increases the corrosion resistance to reducing acids and against pitting attacks in chloride solutions. By varying the chromium and molybdenum content, different grades of stainless steel are produced with each suited for varying environments. Due to the resistance to corrosion and staining, stainless steel is ideal material for many applications, especially in the food, pharmaceutical, and chemical industries.

The 300 series stainless steels are considered chromium-nickel alloys and is the largest group and most commonly used. Of the different compositions within the 300 series family, Type 304 stainless is the most widely used followed by Type 316, which has 2% molybdenum added to provide greater resistance to acids and to localized corrosion caused by chloride ions.

Table below shows the nominal composition by mass content for 316 stainless steel

316 SS Table

Because 316 stainless steel provides a high level of corrosion resistance, resists pitting, and has good strength properties, EXAIR manufactures many of its products from 316 stainless steel material so that they can be used in the harshest of environments.

Of the EXAIR products these are available off the shelf in 316 stainless steel- Super Air Knife, certain sizes of Adjustable Air Amplifiers, numerous Air Nozzles, Line Vacs including the Sanitary Flanged style, NEMA Type 4X and Hazardous Location Cabinet Coolers. If you need one of our other products such as the Super Air Wipes or Vortex Tubes made in 316 stainless steel, just let us know. Of course we also have them made from Type 303 stainless steel, in stock and ready for shipment (and aluminum, too!)

EXAIR Founders Day 2019

EXAIR celebrates Founder’s Day each year on February 22nd (or the closest working day) in order to commemorate the birthday of our founder, Roy Sweeney. He founded the company in 1983 and drove EXAIR to become the strong, successful and innovative company that it has over the years. Today would have been his 85th birthday.

We choose to make this day a celebration and a day to mark our ongoing commitment to the service of others in keeping with the values that Roy and his wife Jackie felt (and feel) very strongly about. It is now up to us to continue to look outside our company, outside ourselves and do what we can to improve the world around us.

As we do every year, EXAIR has made significant donations to organizations that are making a difference right here in our area:

• Dragonfly Foundation – supporting pediatric cancer patients and their families
(www.dragonfly.org)

• Master Provisions – supporting those in need with food, clothing and other items in the Greater Cincinnati area and abroad through mission trips
(www.masterprovisons.org)

• Cincinnati Youth Collaborative – supporting vulnerable children and young adults to overcome obstacles and succeed in education, career, and life
(www.cycyouth.org)

• Lighthouse Youth and Family Services – supporting their Safe and Supported program for LGBTQ youth (www.lys.org)

• DAV – supporting disabled American veterans and their families
(www.dav.org)

• Women’s Crisis Center – supporting victims of domestic violence, sexual assault and sexual abuse
(www.wccky.org)

To further our commitment to others, EXAIR established an Employee Volunteer Program last year that enables every full-time employee with at least 90 days of service to volunteer with organizations of their choice during the normal work week with full pay by EXAIR. I am proud to say that fifteen employees volunteered their time helping other organizations in 2018. Through this program, EXAIR and its employees can have a positive impact on dozens of organizations throughout the year.

So as we celebrate today with lunch from one of Roy’s favorite restaurants – Montgomery Inn – and funny memories, we wish Roy a happy birthday. We miss having him here. We remember what he did for all of us and for countless others. And we pledge to continue his commitment to helping those who need it.

Happy Founder’s Day from everyone at EXAIR!
