Dear Joe…….

IMG_2082

Well, Friday, March 28, 2014 marked the end of an era here at EXAIR.  It was the official last day of Joe Panfalone, @EXAIR_JP, #DearJoe.  I know Joe has blogged about his retirement, but in case you didn’t know, he has been with EXAIR for 19 years straight.   That is almost longer than Professor Penurious’ Co-Op has been alive.

When I first started here at EXAIR four years ago Joe would always tell me, just remember kid, I voted for you.  The trick is he wouldn’t say whether he voted to hire me or not to hire me, just that he voted.   I have a feeling that I was to Joe, like Dennis the Menace was to Mr. Wilson.

No matter what the question or what he was doing, I wanted to know.  Joe was more than willing to tolerate all the questions, too. It’s almost like he has had kids before and that his patience has been tried before.  No matter what would happen, he would just keep going back to the fact that he voted for me.

Joe hasn’t only taught me a lot about applications, theory behind product, and how to skirt around HR, he has taught me how to be a better manager, not to sweat the small stuff, and that when you find something good you better hold on to it for dear life.

One of the many things Joe is known for around here is his extensive palate; in other words, he’ll eat anything.  Even my wife knows that if we have some leftovers or cake that we don’t want to eat ourselves, just send it in and Joe will eat it.  He even returns Tupperware clean as a whistle with a note saying “More Please”.

The fact is, I am extremely excited to see Joe move on to the next chapter of his life.   I can only hope that it will be better than he has made all of ours.

One last thing, Joe did make the mistake of promising to meet up this Spring / Summer and help me teach my oldest daughter how to fish.  (Little does he know he’ll pretty much have to teach me, too!)

 

Thanks for everything Joe!

How can you protect people that don’t protect themselves?

My sister-in-law and my nephews are traveling from Columbus to Cincinnati for a visit this weekend. My nephews are 18 months and 3 years old, and they will find any sharp, fragile, or flammable object within walking, crawling or climbing distance. Of course they don’t consider these things dangerous. All they see are fun new toys. Yesterday, I battened down the hatches for the nephew hurricane that will be barreling down Interstate 71 this weekend, and there were more dangerous or scary items in the house that the nephews will want to use than I could hide.

At EXAIR, we strive to provide products that intelligently use compressed air, but everyday we have customers who are using compressed air in unsafe manner. We try to educate many of our customers and the industry as whole of the dangers and that can be associated with compressed air. The chief concern is that compressed air may cause an embolism by forcing air into the bloodstream through a break in the skin or body opening. Because of this risk, OSHA has laid down several rules for using compressed air for cleaning purposes inside the work place. To quote the OSHA Instruction STD 1-13.1, “The requirements for dynamic flow are such that in the case when dead ending occurs a static pressure at the main orifice shall not exceed 30 psi. This requirement is necessary in order to prevent a back pressure buildup in case the nozzle is obstructed or dead ended.

An open pipe used for cleaning violates this rule. Yet everyday I speak to a customer who are using open pipes to remove chips, dust or water from parts. If a employees hand is trapped against the open tube, serious injury will result. EXAIR’s Super Air Nozzles are designed with multiple openings and fins to protect those openings, so that air always has a path to escape.

 

Nozzle Lineup

 

The other safety concern with an open pipe is the noise level.  Open pipes can produce noise levels over 100 dBA which violates OSHA’s standard for maximum Allowable Noise Exposure for even 2 hours per day.  EXAIR Super Air Nozzles will reduce noise levels to create a safer more productive work environment.

When Is A Half Inch Not A Half Inch? When It’s Half Inch Pipe, Of Course!

People have been using pipe to transport fluids for thousands of years. Archeologists have discovered evidence that the Chinese were using pipes made of reeds for irrigation as early as 2,000 B.C. Lead pipe began to supplement, and eventually replace, the Roman aqueducts in the first century A.D. In the early 1800’s, someone got the idea to use gas burning lamps to light city streets, and, over the next few years, men like James Russell and Cornelius Whitehouse came up with better and better methods of mass producing metal tubing and pipes.

Over the course of the 19th Century and the Industrial Revolution, iron pipe came to be manufactured in standard sizes, which were called out by the inside diameter of the pipe. ¼” pipe had a ¼” ID, ½” pipe had a ½” ID, ¾” pipe had a ¾” ID, etc. Iron pipe could be found in any facility that needed to move a gas or a liquid: factories, power generating stations, chemical plants…you name it.

As engineers and metallurgists came up with new ways to produce pipe, technological advances led to the ability to decrease the wall thickness and still maintain high structural integrity. This was a HUGE improvement: not only could piping manufacturers make more pipe with less material, bringing down the cost, it was also lighter in weight, making it easier to transport, handle, and install. Because of the massive amount of existing piping already in place, it made sense to keep the outside diameter the same, so that all the fittings would match when these facilities went to replace worn out or damaged pipe. So, the inside diameter was increased. That’s why, today, ¼” pipe has a 0.36” ID, ½” pipe has a 0.62” ID, ¾” pipe has a 0.82” ID, etc. Lower cost, lighter weight, more flow capacity…it’s all good, right?

Well, yes, but sometimes, it can lead to confusion, especially when we’re talking about properly sized compressed air lines. See, we know how much compressed air will flow through certain sized pipes of specific lengths. The Installation & Operation Instructions for all of our products contain recommended infeed pipe sizes to ensure sufficient air flow. Keep in mind, these are Schedule 40 pipe sizes, and should not be confused with hose or tubing sizes, which usually report the outside diameter but could also report the inside diameter, depending on the source.

Consider this example: you want to install an 6” Super Air Knife in a location 10 feet from the compressed air header. Following the “Infeed Pipe Size Length of Run” column (10’) down, we see that this will require a ¼” SCH40 pipe, which has an ID of 0.36”. If you want to use hose or tubing to supply it, that’s fine – it’ll have to have a 3/8” ID, though, or you’re going to risk “starving” the Air Knife for air. If you choose a 3/8″ tube remember that dimension is usually referring to the outside diameter of the tube and automatically means your inside diameter is smaller than we would recommend.

Compressed Air Quality

In a recent conversation with an end user, we scratched the surface on compressed air quality.  In this case, the customer wanted to maintain their Super Air Knives as well as possible through preventative maintenance, and through supplying sufficient quality compressed air.  At present, they were unsure of the required compressed air quality for our products, and called EXAIR to seek direction.

When it comes to compressed air quality, ISO 8573 provides detailed standards on air quality classes for various levels of contaminants.  At times you may see a three digit code describing a filter, and this code refers to particulate, moisture, and lubricant classes of the filter (specified in that order).  The classes used to define these codes can be found below.

Compressed Air Quality ClassesISO 8573-1 Compressed Air Quality Classes

For example, if the application in question requires process air for assembly in a clean room with low particulate, low moisture, and low oil content, a filter rating of 1-1-1 would be desired.  EXAIR Automatic Drain Filter Separators are suitable to filter particulate to 5 micron, and our Oil Removal Filters are capable of trapping sub-micron particles down to 0.03 micron.  Supplying compressed air to these specifications is suitable for all EXAIR products.

Providing clean, dry compressed air is important to prevent contaminants from damaging components or manufactured products in an application.  Contaminants can enter the system at the intake of the compressor, through the compressor itself, or through the compressed air piping in the form of rust or pipe scale.

Determining the quality of air needed for an application can be done by considering the end use of the compressed air.  If the application requires plant air, there is no need to produce or maintain process air within the facility.  Compressed air quality can be tailored to the specific application at the point of use.

Joe Will be Retiring Soon

new paradigm ahead

As the title of my blog states, our long-time friend and colleague, Joe Panfalone will be retiring soon. And as the sign above indicates, that means a new paradigm awaits Joe and how he lives his life from now on. Instead of being awakened each day by a rude alarm clock to signal the beginning of his day, he will get up when he is darn good and ready! And instead of fighting the rush-hour traffic to get to and from work each day, he can leave to go wherever he wants, whenever he wants and however he wants, except maybe for those doctor appointments!

Joe isn’t quite ready for the old folks’ home though. He has plans to do some travelling, go camping, fishing and maybe even hiking with his rather new additions, the bionic knee and a left-handed machete! He has been working on getting his camping gear together over the last year or so. He is a great prepper. Some of the doomsday folks could take a lesson or two from him!

In all seriousness Joe, as you move on to add some new chapters to your already long book of life, it is my sincerest hope that you enjoy every minute of it in high spirits, good health and in the company of good friends and family.

Your young buddy.

Office Rule #1

Today I was smacked in the face with the reminder of many applications I have helped customers with over the years.  As I walked through the door into our lunch room I was hit in the face with a very strong odor. This is why Office Rule #1 is, “DO NOT microwave fish in a common area microwave.” The odor was microwaved fish.  Now it doesn’t matter who cooked the fish, all that mattered was it had not only worked its’ way through the kitchen but also the entire office and then it was being vented into our manufacturing area.   Needless to say, the force was strong with this one.   That is when I was reminded of the fume evacuation applications I have done through the years.

Air Amplifier Removing Welding Fumes

If only we had a windows that opened, we could have used an EXAIR Super Air Amplifier to quickly and efficiently evacuated the air out of the kitchen area. I have helped many of my customers evacuate fumes from anything from a mining shafts to welding fumes. Using a small amount of compressed air the Super Air Amplifiers move large volumes of air. Super Air Amplifiers are also effective for moving large volumes of air for cooling and blow off applications.

Have a cooling, blowoff, or evacuation application? Call our application engineers and they will help you select the appropriate model air amplifier.

Out With The Old & In With The New

Hopefully today I will put the finishing touches on a small side project I have been working on here at EXAIR.   Earlier this week we received an upgrade for our front entry.  It was a small feat to get this piece from our loading dock to the front lobby but the guys in our shop and several engineers (watching only) got it done.   What is the new piece you ask?

IMG_3859

A new and much larger display case.

Not only had the old case gotten too small to house even half of our products, it had also gotten to where we couldn’t fit all of the awards our products had won over the past years.  In this case alone we are displaying 16 total awards which span multiple product lines.   One entire shelf has been dedicated to our Air Nozzles & Jets products because they have won 7 awards on their own.

Along with the new case we added  another award which was given to the EXAIR Digital Flowmeter.  This award was from Environmental Protection Magazine, for being their 2013 Product of the Year in the Energy Management division.   This award honors a product which is found noteworthy for making those who are in the environmental field easier.

The case isn’t quite full but it will continue to get more occupants as the year goes on as we design more products and (hopefully) receive additional awards.
