Hey EXAIR, How Do You…?

Years ago it wasn’t uncommon to post a question you have to a website called a forum in order to get help figuring out how to do something. This of course was back when forums were still the rage and videos on the internet were not nearly as popular as they are today. It wasn’t very long after when trying to learn how to do something has now turned into an internet video search and you generally come up with half a dozen people explaining how to do the task at hand. Notice, I didn’t say that they are explaining how to do it well or do it right.

EXAIR started making how-to and tips and tricks videos back in 2010. We have consistently released new videos that cover the vast reaches of our products. Some are more subject matter expert videos, others are tips and tricks / how-to and finally you have the more in depth product knowledge videos.

The best part of this is that our Application Engineers are the ones that made/make them and so you get to see us, hear us discuss the proper way to proceed with products or situations. You can also call and talk to us if there is anything we may have left out. We always look forward to walking through troubleshooting, new installations, or even theoretical applications of products. If you want to look through the videos, you can search here on our blog, you can review them on EXAIR.com or even our YouTube channel.

Feel free to reach out and let us know, we are always here to help.

5 Important Factors When Selecting an Atomizing Spray Nozzle

The most recent EXAIR Webinar is up and ready to be viewed as an on demand video. This presentation showcases five important factors when selecting an atomizing spray nozzle. Throughout the webinar you will gain several key takeaways that are outside of the five factors as well. If you have a liquid spray application and are not sure where to start, this video has a wealth of information for you. As always, the Application Engineer department is also here and ready to assist as needed. We can walk through any application with you and help right over the phone, through email, or even live chat.

How To Plumb and Use EXAIR Model 9040 Foot Valve

If you’re looking for a convenient, hands-free (but still operator controlled) method of operating a compressed air product, look no further than the EXAIR Model 9040 Foot Valve. Here’s how to install and operate it:

This is one of many ways we can help you optimize, automate, and simplify your use of your compressed air.  If you’ve got an application you’d like assistance with, give me a call.

Atomization: What is it?

Atomization is a word that can be seen throughout the industry in rinsing, coating, painting, lubricating, and cooling applications. The act of atomization is simple, we often refer to it when looking at liquids and it means to break up the liquid stream and form fine droplets.  This is essentially a transfer of energy. There are two mainstream methods to atomize liquids for an application, both with their own advantages.

142 distinct models. 8 different patterns. Liquid flow rates from 0.1 to 303 gallons per hour. If you’ve got a spraying application, EXAIR has an Atomizing Nozzle for you!

The first is air atomizing. This action is done by combining a stream of compressed air with either a pressurized fluid or a siphon/gravity fed liquid.  The air stream can be combined with the liquid internally to the nozzle, hence Internal Mix Atomizing Nozzles. It can also combine outside of the nozzle, like the External Mix Atomizing Nozzles. We have blogged before on where to use each of these as the reason to select between Internal Mix or External Mix is its own topic.

Benefits to air atomization are, smaller droplet/particulate size is achievable.  The compressed air atomization gives the ability to break up more viscous fluids to get better coverage or thinner layers of spray.  Air atomization also gives the ability to use smaller amounts of liquid because the air takes up a portion of the total flow exiting any nozzle.

The second type of atomizing nozzles are hydraulic atomization. This uses the energy from the liquid being pressurized to break up the liquid stream.  Sometimes there are physical impacts within the nozzle that cause the atomization, other times it is just the liquid leaving an orifice that causes the atomization. This gives the ability to still spray a liquid into droplets of various shapes, dimensions, and flow rates. The lack of compressed air often results in larger droplet sizes as well as higher liquid flow rates. Because the liquid has to be pressurized to certain levels it also becomes difficult to spray higher viscosity fluids through hydraulically atomized nozzles.

Benefits to hydraulically atomized spray nozzles range from stronger spray force for rinsing, ease of installation from not needing to plumb compressed air, ability to flow slurries, or other liquids that may clog or dry due to the design of air atomized spray nozzles.

If you would like to discuss the correct nozzle for your spray application, feel free to contact us.
