If Only I Had A Line Vac When I Was A Kid

I read an article earlier this week talking about the types of toys you played with as a child and what your career lead to.  Then I got to thinking, what if I had some EXAIR products and an air compressor when I was a kid?  What kind of madness could ensue?

The first item that came to mind for me was using a Line Vac.  This would not only be used to propel Hot Wheels a record breaking speeds into the loop of death or see how many full size cars the scaled car can jump.   Also what happens to a full size car when you launch a small die cast car into it?   Needless to say that is not all the ideas I have had for taking the orange track to the next level.

In case cars weren’t your thing, a Line Vac would be great to launch a parachute assault using your favorite G.I. Joe with a parachute, not to mention go quite higher than I could ever through it.  It could also help launch zip lines or remove excavated dirt out of bunkers.

When I was a child, I didn’t know what compressed air or an air compressor was other than that my dad used one to inflate bike tires.   Now, I work around compressed air every single day and I make sure to introduce my girls to it whenever possible,  especially how to use compressed air safe.

The point is, a lot of the toys I played with as a child kept me thinking about mechanical ways to do things and thus I ended up with a degree in Mechanical Engineering Technology.  Hopefully by introducing kids today to our products and the many uses they will help perpetuate the design cycles of Intelligent Compressed Air Products.

EXAIR’s Cabinet Cooler® Systems Withstand Every Environment

EXAIR’s second product to win Plant Engineering Magazine’s Gold Award for Product of the Year is EXAIR’s Dual 316 Stainless Steel Cabinet Cooler System.

EXAIR Cabinet Cooler Systems are used continuously in some of Industry’s harshest environment to protect crowded, overheated, and expensive electronic controls from heat failures and alarms.  Dual 316 Stainless Steel Cabinet Cooler Systems provide 5,600 BTU/HR of cooling through (2) electrical knockouts and a compressed air line.  The 316 Stainless Steel NEMA 4X Cabinet Cooler Systems are UL Listed for wash down environments for food service and pharmaceutical application.

Fans, air conditioners, and heat exchanges use ambient air and are susceptible to failure from dusty environments when the filters clog or mechanical components fail.  With no refrigerant, motors, or bearings, Cabinet Cooler Systems require no maintenance and can run for years or decades. Cabinet Cooler Systems prevent downtime on the most critical components in your facility.

These coolers are used to protect the most sensitive electrical components in the United States.  A customer disposes of chemical weapons and monitors the exhaust gases of their facility with electronic components mounted to the outside of the smoke stack. This enclosure is exposed to the elements and the heat of the desert sun. Any failure or alarm in the equipment forces the process to shutdown.  A Stainless Steel Cabinet Cooler System protects these electrical components from overheating.

Stainless Steel Cabinet Cooler Systems have been used on ships, power plants, medical device manufacturing facilities, and bakeries to keep heat out of their enclosures.  They also feature an added benefit that fans, air conditioner and heat exchangers don’t.  The EXAIR Cabinet Cooler Systems apply a positive pressure to the enclosure to push out any dust that may otherwise gather inside your cabinet.  This positive pressure improves air flow and limits dust building up on electrical components.  When dust collects on components, it acts as an insulator trapping the heat against your critical controllers.  This trapped heat can lead to premature failure even with sufficient cooling inside the enclosure.

As this spring heats up and summer begins, keep the Cabinet Cooler System in mind as great solution to your over heating issues.

Full Flow Air Knife Increases Airflow By 3000%

Condensor Housing

Inside of the housing of the photo above is an EXAIR Full Flow Air Knife. The housing serves as a shield to a condenser on a specially built machine for one of the Big Three U.S. auto manufacturers. The purpose of the air knife within the housing is to supplement heat removal by passing large volumes of ambient air over the condenser, thereby helping to return the gaseous fluid to a liquid state.

When compressed air was supplied to the air knife in this photo, there was very little airflow. Knowing that there was something amiss, and that an Application Engineer could offer potential solutions, the OEM called in to EXAIR.

Immediately upon seeing the photo, the root cause of the problem was evident. There was no ambient air available for the air knife to entrain. It looks like an attempt was made to open the housing *in the bent edges at the top of the housing), but it was not enough.

Removing the housing from the machine revealed the following internal installation.

Condensor Housing Internal

With such a setup, there was no entrainment of ambient air, and the total airflow was only a fraction of what it should be. Removing the current shield and fabricating an alternate design which allows ambient airflow solved the problem in this application. Compressed air use remained low, and total airflow was increased by 3000%.

EXAIR products keep compressed air use low and performance to a maximum. For help with your application, contact an EXAIR Application Engineer.

Not Just Another Day At The Ballpark

Sunday was a fabulous day to be at the ballpark. My family scored some great seats, right behind the Reds’ dugout. I got my first (ever) foul ball at a Major League game. Notice I didn’t say “caught” – it bounced off the guy’s hand in front of us, over my oldest son’s outstretched glove, off the empty seat behind him (why those seats were empty, I have no idea), and rolled under my seat.

We also saw our first instant replay review of a play by the umpires. It took every pixel of high definition that the camera had to allow the officials to decisively rule the runner safe at first…it literally came down to how fast the first baseman closed his glove on the ball as he caught it.

Notice the Braille at the bottom.  I'm sure this has NOTHING to do with the debate about Instant Replay.

Notice the Braille at the bottom. I’m sure this has NOTHING to do with the debate about Instant Replay.

The most memorable part of the game, for me, was watching the outcome of two critical decisions by the respective team managers: In the eighth inning, Tampa Bay Rays pitcher Josh Lueke was directed to intentionally walk Reds’ slugger Jay Bruce to load the bases. Bruce had doubled in the fifth, so it wasn’t necessarily a bad call. That is, until Reds’ manager Bryan Price quickly called on Chris Heisey to pinch-hit, following Bruce. Heisey fouled off the first pitch, and then parked the second one just over the right field fence. I’ve been at the ballpark for some dramatic home runs, but that was the first time I’d witnessed a grand slam up close and personal.

To be honest, I thought for a second about skipping the game. We got the tickets at the last minute, and I already had burdens on my schedule for Sunday afternoon. In the end, I’m glad I put that other stuff off, because, years from now, I wouldn’t remember that day I mulched the flower bed, cleared the brush from the wood pile, and filed my taxes (two days early, I might add), but that was a one-of-a-kind day at the old ball game.

My mind still goes back to the intentional walk, and subsequent pinch-hitter decision that led to the grand slam…never underestimate the benefits of being able to draw from the skills of a talented team. We do that every day, here in the Application Engineering group at EXAIR. We don’t miss a chance to learn, or teach, when one of us is presented with a challenging application. If you have a need for a compressed air solution, and you ask one of us for help, know that you’re getting the experience and knowledge of the whole team. Try us.

Award Winning Compressed Air Nozzle Saves Hundreds of Dollars Annually

awards2013_1126_400wide

 

EXAIR’s 1 Inch Flat Super Air Nozzle won the Gold Award for Compressed Air from Plant Engineering in 2014. We won the award for the immense savings that our customers reap by using this nozzle to replace open blow offs. While saving compressed air, we also reduce noise level and comply with an OSHA regulation 192.242(b).  Do not leave that blow off open. It is costing you everyday in dollars; it may cost you more in OSHA fines later, and it will cost your employees hearing later.

A 1/4″ copper tube can use 33 SCFM at 80 PSIG of inlet pressure. This homemade blow off will use 1,980 standard cubic feet per hour. Typical industrial compressed air cost $0.25 per 1,000 standard cubic feet.  That 1/4 copper tube is costing you $0.50 every hour to run. Each year, one 1/4″ copper tube costs $2,970*.

The 1 inch Flat Super Air Nozzle, model 1126, uses 10.5 SCFM or 22.5 SCFM less than 1/4″ Copper tube.  Saving your company 22.5 SCFM, is the same as saving $0.34 every hour or $2,025 every year.*  Saving 22.5 SCFM also, means that your compressor system doesn’t have to work as hard.  A 5 HP compressor will put out 20 SCFM, so replacing one 1/4″ Copper Tube with a model 1126 will save you from upgrading compressor system as your company expands.

Regardless of the $2,025 you just saved by replacing the homemade blow offs with engineered nozzle, it is also an industry best practice because it can lower the noise exposure for personnel and prevent any harm from dead end pressure.  OSHA standard 29 CFR – 1910.95(a) requires that if an employee is exposed to greater than 100 dBA for 2 hours, he or she needs to wear hearing protection.  A 1/4″ copper tube will easily exceed 100 dBA.  The model 1126 will lower the noise level to 77 decibel, 13 dBA lower than the OSHA requirements for an 8 hour day.

Finally, the 1″ Flat Super Air Nozzle cannot be dead ended, which protects your employees from serious injury. In the event, that a compressed air orifice is blocked with no means of escape, air may enter the bloodstream from an open cut or wound in the skin. Compressed air must be kept below 30 PSIG to eliminate this danger when using an open pipe, tube or many commercial air nozzles. With EXAIR nozzles, pressure to the nozzle  can remain at line pressure and produce the maximum velocity and force for a successful application.

Adapting To The Situation At Hand

Earlier this week I received a call from a customer who had an issue in his facility with the hand held blow guns the operators were using.   The units he had were simply too loud and he was trying to get below the 85 dBA threshold for hearing protection.  Not to mention they were using a large volume of compressed air.

I discussed the application with the customer only to discover they are blowing dry aluminum chips off a table and need a three foot extension so the operators can easily reach all extents.   The nozzles they had on their existing blow guns were essentially a cross drilled “safety nozzle”.  The customer was using the same model air gun throughout his facility at a total of 33 machining centers.   Each unit had a gun with a 3′ extension and a cross drilled nozzle like tip.

After discussing the amount of chips and what they were using I recommended he utilize a newer style adapter we have that would appear to work on his existing gun with the existing extension.  This means, rather than having to replace the entire air gun, extension pipe, and nozzle, he was able to purchase a simple adapter along with our model 1100 Super Air Nozzle and retrofit his entire facility.  This cut the budget needed by more than half of other solutions he was looking into from other companies.   Picture of the nozzle and adapter are below.

This was just another adapter for EXAIR but it was the right adapter for the customers existing product.  So if you have an existing blow off and you don’t want to replace the entire blow off device but you want to try and upgrade your system, contact us.

Questions for Selecting an Atomizing Spray Nozzle

AN1010SS

Did you know that the air and liquid caps of EXAIR Atomizing Nozzles are interchangeable? Maybe you do. But, do you know which parts are interchangeable? And, did you know that EXAIR Application Engineers have a quick reference chart for such information?

When it comes to liquid spraying, our customers will write to me for application assistance, technical specifications, and potential uses for Atomizing Nozzles. Sometimes the need is for new methods to apply liquid in an existing application.

Rubber Extrusison Painted with AN1010SS

This was the case in the photo above. The end user needed to apply a thin line of paint on a rubber extrusion. After the rubber is dried, it needs to be marked for easy identification during later handling. Using an AN1010SS, the end user has the option to apply atomized paint, and to automate the process so that paint is applied only as needed.

Atomizing Nozzles are also suitable for dust suppression (for example, at a waste transfer system), humidification (such as soften wood for processing), improving costly liquid usage, or spraying oil lubricant.
The best way to categorize an application for use with an Atomizing Nozzle is through a series of (5) questions.

  1. What is the desired spray pattern?
  2. What is the area size to be covered?
  3. How much liquid flow is required?
  4. Is there a pressurized liquid source?
  5. What is the viscosity of the fluid to be atomized?

Based on the answer to these questions the proper Atomizing Nozzle can be selected. If you need clarification on how these questions correlate to model number selection, a full staff of engineers are available for chat through EXAIR.com or over the phone/by email.
