One of the more common questions we get here in the Application Engineering department at EXAIR is…
“What’s the best angle to position a Super Air Nozzle?”
The simple (and perhaps a little snarky, but I swear that’s not intended) answer is…
“The angle it takes to get the results you need.”
But wait, there’s more…we’re not going to leave anybody hanging like that. Many blow off applications are going to be best served by a “sweep” of air, at a low angle. That will be ideal for removing a light layer of dust from a relatively flat and smooth surface. A bit larger angle, relative to the surface, may be necessary if you need some impingement force to dislodge sticky, clumpy, or mildly adhesive debris. Rarely will you want to blow directly, at a perpendicular angle, to a material’s surface. An exception to this might be if you’re trying to remove excess moisture from a porous and thin material, like a web fiber.
Regardless of what angle you need to aim your Super Air Nozzle, there are several ways to do it. You can use a compression fitting them onto bendable copper tubing…just don’t bend it too much or too often. We’ve got Stay Set Hoses that allow for quick & easy repositioning…they come in lengths from 6″ to 36″, and are in stock.
If you want to hold it in place firmly and securely, you’re looking for a Swivel Fitting. They’re available for almost all of our Super Air Nozzles, from the Atto to the 1″ NPT Model 1114 High Force Super Air Nozzle. They offer 50° of total movement, and are made of Stainless Steel for durability in most any environment.
EXAIR Swivel Fittings have male NPT threads on one end, and female NPT on the other. The smaller Swivels, for the Atto, Pico, and Nano Super Air Nozzles, have M4x0.5mm, M5x0.5mm, and M6x0.75mm female threads, respectively, in the ball of the swivel itself for direct threading of these small Super Air Nozzles.
Swivel Fittings can also be used with a host of other EXAIR products. In addition to the Super Air Nozzles, for example, they’ve historically been very popular with our Air Amplifiers. Here’s a short informational video showing just how versatile they are:
EXAIR Intelligent Compressed Air Products are made to be easy to install & operate. This is our intent from Research & Development, to Shipping & Receiving. If you have questions, give me a call. I want you to get the most out of our products!
