Bad News, Good News, Better News

Recently, I had the pleasure of solving an application for a steel pipe manufacturer. To clean the inside diameters of their freshly-washed pipes, they were using open end blow offs: the ever-popular and easy-to-make, but loud and inefficient crushed-end tubing. I got excited, because this was my first chance to discuss our brand-new Back Blow Nozzle, which is aimed (pun intended) at cleaning inside diameter surfaces. That’s where my story develops a “bad news/good news/better news” pattern…

The bad news: The pipes that need cleaning are up to 20” in diameter…a little too large for our Model 1006SS ¼” NPT Back Blow Nozzle to be completely effective.

The good news: The user already had a system set up, using the aforementioned “homemade” blow offs, which looked something like this:

Easy to make, hard on your ears...and your air compressor load.

The better news: They were able to easily adapt their system to install our Model 1120 High Force Super Air Nozzles, which lowered their compressed air consumption as well as the noise level of the operation.

That's the Model 1120 on the far right.

The moral to this story is, the solution may not be the first one that comes to mind. At EXAIR, that happens all the time. Line Vac questions turn into Air Amplifier answers, and vice versa. Cold Gun calls turn to discussions of Adjustable Spot Coolers. We’ve got three styles of Air Knives to choose from…they’re all perfectly suitable for a wide range of general industrial applications, but they each have their own particular advantages in certain situations. If you have a compressed air product application that you’d like to discuss, EXAIR is your best bet for the most efficient, quietest, quickest solution. It’s like I always say:

New Atomizing Spray Nozzle Can Spray the Inside of a Duct

The second atomizing air nozzle that EXAIR introduced in Catalog 27 is the Internal Mix 360 Degree Hollow Circular Pattern Spray Nozzle, part number AT1010SS. This nozzle produces circular air pattern perpendicular to the flow of most atomizing air nozzles.  The AT1010SS can create a mist across 53 inch diameter circle.  The nozzle is constructed of 303 Stainless Steel for use in corrosive environments. It operates on a continuous stream of compressed air and pressurized liquid.  The AT1010SS features a compact design that is 3.20 inches long, 1.69 inches wide, and 0.88 inches thick to fit into small ducts or hard to reach corners.

360 degree Internal Mix Hollow Circular Pattern

The 360 degree nozzle, AT1010SS, can generate liquid flows up to 14.7 GPH.  The typical liquid pressure is from 10 PSI to 60 PSI, but can handle pressure much higher.  Contact an application engineer for more details on flow rates at higher or lower pressures. EXAIR has an extensive listing of the flow rates of various pressure on our website and in catalog 27.

This spray pattern is perfect for coating the inside of a pipe with rust preventative, paint, or protective coating. The flow pattern would also be able to coat a variety of duct shapes.  Mounted over a process, the nozzle pattern is also great for dust suppression, humidification and cooling over a wide area.
