Last year, I took on a new project – restoring a 1973 Mustang Mach 1. Ain’t she beautiful? Well, she will be some day anyway…
It’s been a busy year (arent’ they all?!?), so when I got a few free hours to work on it the other night, I jumped at the chance. As anyone who’s ever worked on an old car knows, getting all the dirt, rust, grime, opossum residue, etc. off the car so you can see what you’re working on is one of the first things you do. Imagine my surprise when I grabbed my trusty Model 1210 Soft Grip Super Air Gun to start blowing off some of the aforementioned debris, only to discover a paltry breeze was all it had to offer. A quick check of my compressed air system (including making sure it was turned on – I speak from experience…) revealed I should have close to 90 PSIG at the gun. I decided to take the Model 1210 in to work the next day for evaluation (We can do this for YOU too, our Efficiency Lab service will test your product for air consumption, noise and force to determine what engineered solution EXAIR can provide to help you save air, increase safety and lower noise levels).
Making sure I had 80 psig at the inlet, I checked the flow and force. As I suspected, something was seriously wrong. I was still only getting a week breeze from the gun, as bourne out by the fact the blowing force was down to 1.3 oz, or 1/10th of the 13 oz it should have had. Flow was similarly low – 3.6 SCFM as opposed to the 14 SCFM we stand behind as the published figure. Something was amiss in the gun itself. Fortunately, it didn’t take long to figure out. I took off the nozzle to discover this:
On the left was the Model 1100 Super Air Nozzle that was installed in the gun. On the right is a new Model 1100 off the shelf. Dirty air much?
Using my favorite nozzle cleaning tool, I was able to quickly remove the dirt, rust and miscellaneous garbage that had been clogging up the nozzle.
Back to the flowbench for a quick check and it was good as new! Even the engineers here at EXAIR are not immune to the effects of dirty air. Now, back home to check my air lines and replace the filter element on my compressed air system!
As engineers, we often find ourselves asking why something doesn’t work the way it used to. The first question I’ve learned to ask over the years is simple – ‘What changed?’ In this case, it was a dirty compressed air supply. If you have one of our products that doesn’t work the way you think it should, PLEASE DO NOT HESITATE to call me or any of our Application Engineers to talk about it. We can discuss your symptoms and get them resolved so your system is operating efficiently. A good cleaning, replacing a filter element, installing properly sized air supply lines or fittings could be the key to getting top performance from your EXAIR product.
