Warranties: Better Safe, Than Sorry!

Not my pool, but hey I can dream right?

The last few months for me have been quite busy to say the least. In this time: I’ve gotten married, gone on our honeymoon, purchased my first home, and am planning for an upcoming business trip to China and Taiwan. While it has definitely been exciting, there’s been a fair amount of stress to accompany it. We were thrust into the wonderful world of home ownership when two days in our pool pump went out. I know, you’re probably thinking, whose crazy enough to buy their first home with a pool? Well, we did it! Needless to say, we were fortunate enough to have also gotten a home warranty with the purchase. We’ve had the pleasure of now also using it on our pool filter and the microwave. All of this in just six short weeks! No one is ever excited when things break around the home, but it sure is nice when you have something to fall back on. A few deductibles later, and we’re off to swimming!

Custom Air Knives, Custom Vortex Tubes, Custom Line Vacs. What About Custom Air Nozzles?

At EXAIR we are far from shy that we offer custom solutions.   As a matter of fact, almost every catalog section has a handful of pictures that are special or custom units that we have made for our customers over the years.   We continue to add special items to our database regularly.   This could be anything from a special length Super Air Knife, a Vortex Tube with a special fitting or temperature setting, sanitary flanges on a Line Vac, or even most recently, a special 2″ Flat Super Air Nozzle.

A closer look at the Safety Wire that holds the bolts from backing out.

This Special 2″ Flat Super Air Nozzle came from the customers requirement to use a mechanical fastener in order to ensure all hardware will not back out or come loose.  The 2″ Flat Super Air Nozzle is already held together by two button head cap screws that are thread locked into place in order to prevent them from loosening.  This customers requirement was not met by our standard procedures, so we stepped outside of the box yet again and have offered them a special 2″ Flat Super Air Nozzle with bolts that are held tight by safety wire.

Safety wire is a very popular practice in Aerospace, motorcycle racing, and even some packaging processes.   The Stainless Steel wire is twisted and wrapped around the bolt heads in a manner that will not permit either bolt from loosening and falling out.   However, it can be removed, the nozzle can then be cleaned, and the safety wire can then be replaced for preventative maintenance needs.

If you are in the need for something that you don’t directly see in our product offering, or maybe you simply need something like a bolt style changed.   Contact us and see what we can do for you.   Chances are, we will meet your needs with ease and even be in a timely fashion.

Dirty Compressed Air Consequences Are Avoidable

I would like to discuss the importance of clean and dry filtered air.  This all comes from some discussions I have had with customers over my time here at EXAIR, as well as from my time in the machine tool industry. It is notable to state that we simply ask for clean/dry air to run through our products, not “instrument” or “process” air which is typically held at a different pressure, temperature, or volume and can be more expensive to generate. All of EXAIR’s products use general plant air and can be cleaned up with simple point of use filters.

Clean and dry compressed air is essential for ensuring a long and easy life of almost any compressed air product.   One product in particular that I have some data on is the EXAIR Line Vac.  The pictures below show the inside wall of a Stainless Steel Line Vac.  This unit was used in a harsh outdoor environment.   The compressor was not maintained and did not have any form of filtration on the lines feeding the Line Vac unit. The first picture shows where all the dirt and particulate were impacting the internal generator wall as it entered the air chamber.

Damaged Generator

The two dark grey marks are actually the impact points on the unit.   There is only one air inlet on the Line Vac, this means that the unit was taken apart during the two months and actually inspected then put back together and the generator was rotated slightly during this process.  These spots are similar to what sandblasting does to metal, just to illustrate how much particulate was in the air stream. Since the air has not yet reached its full velocity within the Line Vac, it has left only those visible surface blemishes.

As the air begins to exit the array of small generator holes it begins to rapidly increase in velocity while it is trying to expand to atmospheric conditions.  Because of this increased velocity, the wear the generator holes experience is greater and as seen below it is causing some extreme wear.

Worn Generator Holes

To give you an idea of what a new generator should look like is below. Here you can see uniform holes that go precisely through the generator.

To prevent a disaster like this from happening to your end-use compressed air products, all you need are some simple, low maintenance filters.   EXAIR offers dirt / water filter separators that will filter your compressed down to 5 micron particulate size.   The will catch the good majority of rust, water, and dirt within your compressed air system.   Then you can also install an oil removal filter which will filter all oils and particulate out of your compressed air system down to 0.03 micron particulate level.

Each of these units are great point of use filtration to keep any of your processes from experiencing what this Line Vac experienced.   If you have any questions about the quality of your compressed air or why you are seeing failures in product on your compressed air system, contact us.

Quality Of A Knock Off and Racing Motorcycles

That’s right folks, the first track day of the year is getting close.  The first for this year will be held at Putnam Park Road Course, with Midwest Cafe Racers Association.  We will be heading out on Friday, April 19th, for the weekend.  The preparations already began a few weeks ago, actually over a month ago.  This year I am not only prepping my track bike, but also my friends track bike.   The best part is, I am learning more and more about his bike, and the bells and whistles that it has.

One of the many parts to prepping the bike for the track was changing out the coolant to a non-glycol based coolant, changing the tires, removing all glass / plastic from the bike.  Not to mention drilling and safety wiring the oil filler cap, oil drain plug, and oil filter.  Those are simply the necessities, we have taken it a step further and changed out some other stock parts for nicer track ready parts.  The main obstacle has been that he elected to go with a non-branded rear set foot control.  These were copies of a very large name brand rear set foot control.  Everything seemed to fit together until I went to install the shift linkage.  The linkage length should be 9″ long, the one they sent with the new set was actually 9-5/8″ long.  Because of this it actually placed the shift lever about 3″ too low and will not work.   Luckily, I have the knowledge and ability to modify things like this.  After cutting the extra length off and re-tapping the hole, the linkage is now to the correct length on the bike, and ready to go racing.

The point to the story is this:  my friend went with the company who said they were just as good if not better than the big name brand, yet considerably cheaper and not made locally.  In the end the quality of the product was not what they made claims of over the internet and they don’t have near the level of support that the brand name does.  After some fixing, the units will work but it could have been a costly replacement as the manufacturer of these doesn’t stand directly behind their product.

Here at EXAIR we have instilled quality into our product and customer service.  If you were to receive a part that doesn’t work, we will be here to help figure out why, and then make the correct actions to remedy your problem as fast as possible.   So don’t always believe what you read on the internet about how great some products are when they are so much cheaper than a well established, market leading brand.
