360° Hollow Circular Atomizing Nozzle Ideal For Treating Ductwork

Published on by exaircorpLeave a comment

There are many times we field calls from customers that fall directly in line with the intended use of one of our products. Such would be the case last week when a customer called looking for  a more reliable way to spray a light coating of rust inhibitor on the inside of a small section of ductwork roughly 9″ in diameter.  They were currently using a liquid only spray nozzle but were having trouble controlling the output flow, as well as the actual spray pattern. They were wasting a lot of the inhibitor as it was starting to “pool” in the bottom of the ductwork which would ultimately leak out onto the production floor and operator’s work area when the parts were prepared for shipment, also creating an unsafe work environment.

Model # AT1010SS Internal Mix 360° Hollow Circular Pattern Atomizing Nozzle

 

After discussing the application with the customer, I recommended our Model # AT1010SS Internal Mix 360° Hollow Circular Pattern Atomizing Nozzle. The circular spray pattern is the ideal solution when trying to coat the inside of a duct with rust preventative. The nozzle produces an even spray pattern up to 53″ in diameter with flows as much as 14.7 gallons per hour of liquid, depending on air and liquid supply pressures. Our Atomizing Nozzles also feature an adjustment valve to provide control of the flow rate as well. The 303ss construction is able to withstand corrosive environments and temperatures up to 400°F (204°C).

EXAIR offers a wide variety of Atomizing Nozzles that can be used to coat, rinse or cool a surface. They are also commonly used for dust suppression due to the wide coverage area they produce. For help selecting the correct Model # for your application, give us a call.

EXAIR No Drip Atomizing Nozzle

In this summer of 2016, we are nearing the beginning of one of the largest sporting events on the planet, The 2016 Summer Olympics. At the heart of this celebration will be sporting events of all kinds. And in the tradition of the Olympics there is always a gold, silver and bronze winner to award the top three athletes in each event.

EXAIR is participating in a competition as well. It isn’t one of a sporting nature, but rather, one of ingenuity and innovation. Flow Control Magazine holds an annual competition for innovations in new products available in industry and we have entered the No Drip Atomizing Nozzle into the competition.

In general, Atomizing Nozzles are used for the application of high value fluids within industrial processes. In some cases where the Atomizing Nozzles are mounted above the target, residual fluid that is left inside the nozzle body can drip out when de-energized and cause un-wanted blemishes on the target surface.

EXAIR No Drip Atomizing Nozzles allow for external adjustment of compressed air and liquid inputs to adjust the liquid spray flow rate as well as droplet size for a wide range of applications. That’s pretty common amongst atomizing nozzles in general. So what is so innovative about the No-Drip Atomizing Nozzles?

We have found a way to control the on/off function of the atomizing spray which supports the no-drip feature as well as the atomizing flow with only one compressed air supply. Most other manufacturers require a nozzle that has a separate control for the small valve within the nozzle and another for the airflow that atomizes the fluid coming through. It is this innovation that dramatically improves the simplicity with which these nozzles can be installed into an application and controlled through typical air automation techniques. It was innovative enough that the US Patent Office granted EXAIR a patent on the design (Patent # 9156045). So, we’ve made the No-Drip Atomizing Nozzle available with 3 different spray patterns and 14 different liquid volume options to suit a wide variety of application need. Operating pressures can fall anywhere between 30 – 250 PSIG to atomize fluids up to 300 centipoise.

If you agree with the US Patent Office on the innovation and think that EXAIR’s No Drip Atomizing Nozzles should be a winner in this competition, we would appreciate your official vote.

Please vote for the EXAIR No Drip Atomizing Nozzles at this link to the Flow Control Magazine’s Innovation Awards page.

Thank you!

Atomizing Nozzle Used in Copper Forming Applications

EXAIR Atomizing Nozzle, Narrow, Round Spray Pattern

 

Copper and its alloys are used in a variety of products from consumer goods like musical instruments, drawer and door pulls, wind chimes, electrical contacts and many other, similar parts that you do not see on more complicated pieces of equipment such as HVAC systems.

Comparatively speaking, copper is quite a malleable metal. That’s what makes it so useful for manufacturing processes such as expanding, reducing, flaring, beading and other similar processes that don’t necessarily involve a cutting or grinding action on the material, but rather a tool that comes into contact with the material to impart a specific shape that makes the made part beneficial to some other product or process.

And so, in the metal forming process, you generally have a hardened alloy tool that comes into contact with the soft copper (or brass) to impart one of the above mentioned effects to the material. With the metal forming process, you have friction that needs to be reduced substantially to aid in the forming process while maintaining the tool integrity and keeping heat generation to a minimum. There are a variety of oil-based lubricants that companies who specialize in this kind of processing, will use to lubricate the raw part prior to forming.

This is the point within the process where EXAIR Atomizing Nozzles can play a significant role in application of the lubrication. By atomizing the lubricant, the customer can have a controlled, even application of the lubricant to the tooling and/or material surface prior to putting the material through the forming operation. By applying a controlled layer of atomized lubricant, the customer can apply the lubricant in a sparingly manner to conserve on how much is used for each part formed. They get the benefit of the lubrication without over-doing it and wasting excess volume of lube applied. This, in turn, allows for a cleaner and safer processing area as well as measurable cost savings for the lubricant as well.

For lower viscosity lubricants (< 300 cP) that require only a light application of material, we have model AN1010SS which can provide a Narrow, Round spray pattern to coat smaller parts. If the part is larger or perhaps starts out as a sheet, we do also have model AW1030SS which can provide a Flat, Wide Angle spray pattern. If the lubricant has a viscosity that is higher than 300 cP, we also have a series of External Mix Atomizing Nozzles with similar spray flow patterns that can be selected for high precision adjustment of the liquid flow and droplet size to suit any need.

If you are in the metal forming industry and you are concerned with application of lubricants in your applications, we be glad to help you pick an Atomizing Nozzle to suit your needs. Contact us to discuss your application.

A Lot Can Happen In Five Years

Published on by Russ BowmanLeave a comment

Five years ago, I wrote a blog about my (then) 11 year old son’s first-ever week away from home at Boy Scout Summer Camp. He’s departing again this weekend, but his troop has decided to venture “out of Council” this year, to Camp Howard W. Wall…it’s on the south coast of the island of St. Croix, in the US Virgin Islands.

They met last week to cover the final (and finer) details of international travel, flight schedules, logistics, etc., and activities…Camp Friedlander has a “blob:”

But Camp Wall has an OCEAN:

Just to put the distance into perspective...
Just to put the distance into perspective…

I’ve been thinking a LOT about the changes I’ve seen in the wide-eyed kid I dropped off at a camp that I drive past twice a day, and the smirking teenager that I’m driving to the airport on Sunday morning. And those changes are providing perspective on not only how fast those five years have passed, but how much can happen in that span.

In 2011, I was a wide-eyed “Dread Newbie” at EXAIR.  One of my very first meetings with the rest of the gang was to be trained on our brand new Atomizing Spray Nozzles…we only had three styles to choose from, but two of them came in four distinct models, and one came in FIVE. They were ALL Internal Mix, because hey, who doesn’t like the maximum range of adjustability that comes with being able to vary your flow rate and spray pattern size by adjusting liquid AND air supply pressures?

OK; it turns out that was just the beginning…within the year, our Engineering Department had developed:

External Mix – three styles, thirteen distinct models, to allow for independent adjustment of flow rate (by liquid pressure) and spray pattern (by air pressure.)

Siphon Fed – two styles, seven distinct models, that could be siphon OR gravity fed, for situations where it’s not practical to pressurize the liquid supply.

And, four years after that, looking back, it seems like THAT was just the beginning…we now have:

*Two sizes – the original 1/4 NPT and the new(er) 1/2 NPT.
*Sixteen styles – each available with our No-Drip option (so technically I guess we have thirty-two)
*Forty-five distinct models – we’ve got a flow rate/spray pattern combination for just about any application

And, like the rest of our catalog products, they’re all in stock, ready to ship today, on time, like we do 99.97% of the time…that’s actually one thing that HASN’T changed in the 17 years that we’ve been keeping track.

If you’d like to talk about Spray Nozzles…or any EXAIR products (old or new,) give me a call.
