A few years back, I had the pleasure of working with a machine shop manager who wanted to reduce the compressed air consumption in their facility. They had ten lathes, machining high-tech plastic products, and used crimped copper tubing to blow off chips and shavings as the parts were turned. They ran continuously — as did the air compressor — which occasionally caused header pressure to drop below the level required for operation of the pneumatic chucks & tool changers.
After some discussion and an Efficiency Lab test of one of their crimped tubes, I recommended our Model 1100 1/4 NPT Zinc Aluminum Super Air Nozzles. They’re our most popular engineered Air Nozzle for typical industrial blow-off applications. They generate a forceful, focused blast of air that’s ideal for chip removal on machine tools, and they’re ideally suited for a number of other uses as well. They bought ten (one for each machine) and installed them one afternoon, right before close of business, by cutting the crimps off the copper tubes and fitting them with simple compression fittings. The whole operation took about five minutes. When the machine shop manager arrived the next morning, he was at first alarmed because there was so little noise coming from the shop (he thought something was wrong with the machines) and then impressed when he found all the lathes were running, and the Super Air Nozzles were so much quieter than the crimped tubes.
While our Model 1100 Super Air Nozzle is our most popular one, EXAIR makes a wide range of engineered Air Nozzles to meet the needs of almost any blow-off application. If you’re replacing something else, we can test your current device(s) in our Efficiency Lab (like we did the crimped copper tubing here) and determine the Air Nozzle that most closely matches the performance required for your application.
If it’s a new application, we have tools at our disposal for proper product selection too:
- The Catalog: Our Air Nozzles & Jets catalog section lists them all, from smallest to largest, with performance data, dimensions, and airflow patterns. I actually like to start with the airflow pattern: once we know the size & shape of the needed/desired flow, we can narrow down our selection.
- Application Database: At last count, we had over 200 blow-off applications written up. Now, that includes Air Nozzles as well as Air Knives, Air Amplifiers, and Safety Air Guns (which have Air Nozzles on them), but keep in mind what I said about picking the size & shape of the airflow.
- Engineering Assistance: If you’re short on time, find yourself completely stumped, or just want a 2nd opinion on the best product for your application, we’re here from 7am to 4pm Eastern Time to help you over the phone, in a Live Chat, or at an Engineering Consultation web meeting. You can also email techelp@exair.com, 24/7, with details about what you’re after.
At EXAIR, we want to help you get the most out of your compressed air use. If you want to find out more, give me a call.
