Atomizing Nozzles – No Drip Deflected Flat Fan and 360° Hollow Circular

EXAIR manufactures three types of Atomizing Nozzles – Internal Mix, External Mix, and Siphon Fed.  Within the Internal Mix family, there are two specialty nozzles, the Deflected Flat Fan and the 360° Hollow Circular patterns.

Internal Mix nozzles are for pressure fed applications not requiring independent air and liquid control.

The model AD2010SS is the No Drip version of the Deflected Flat Fan and is shown below. Our patented No Drip design prevents unwanted post spray drips from wasting expensive fluids or ruining product finishes. The benefit to this design is that no secondary compressed air line is necessary to activate the on/off valve for the liquid, which is the case for competitive nozzles.

Model AD2010SS – No Drip Internal Mix Deflected Flat Atomizing Nozzle

The Deflected Flat Fan patterned nozzle is designed for applications where space is a limited.  The spray pattern is at a right angle to the orientation of the nozzle, allowing the spray to be placed precisely where it is needed in tight quarters.  They are ideal for coating the insides of enclosures and ductwork.

AT2010SS – No Drip Internal Mix 360° Hollow Circular Atomizing Nozzle

The 360° Hollow Circular patterned nozzle is designed for applications where the spray pattern is to be orientated away form the nozzle in all directions.  They are ideal where a smooth and even coating is needed on the internal surface of a pipe or duct.  They are also good for processed where a mist is needed over a large area, including dust suppression, humidification, and cooling.

The No Drip feature is a patented† design that has the added benefit of positively stopping the liquid flow when the compressed air is shut off. Post spray liquid flow can cause quality issues from unwanted drips on painted or coated surfaces.  Also, the No Drip feature helps to conserve and save on liquid use, reducing costs of expensive coatings or chemicals.

When the compressed air supply is shut off, the No Drip nozzle positively seals off the flow of liquid, eliminating over spray and drips. The design allows for just one compressed air line, there is no need for an additional to control the No Drip mechanism.

If you have questions about Atomizing Spray Nozzles, or would like to talk about any of the EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

† Patent #9156045

 

Product Overview: No Drip External Mix Atomizing Spray Nozzles

EXAIR’s Atomizing Nozzles are commonly used to clean, cool or coat parts as well as humidification or to control dust. They are constructed of 303ss, providing superior corrosion resistance and are able to withstand temperature up to 400°F (204°C).

The Atomizing Nozzles are separated into 3 categories – Internal Mix, External Mix and Siphon Fed.

For today’s topic, we will focus on the No Drip External Mix Atomizing Nozzles.

No Drip External Mix Atomizing Nozzles provide the highest flow rates

The External Mix Atomizing Spray Nozzles require a pressurized liquid source and compressed air source to produce a mist of atomized liquid. With the liquid and air being mixed external to the nozzle, they are able to handle higher viscosity fluids above 300 cP.

Our patented No Drip feature positively stops the liquid flow when the supply air pressure drops below 20 PSIG for 1/8″ NPT Nozzles or 30 PSIG for the 1/4″ or 1/2″ NPT. By incorporating this feature into the design, it eliminates the need for any additional valves or supply lines.

Available flow rates range from 2 GPH for our Model # EF9010SS 1/8″ No Drip External Mix Narrow Angle Flat Fan Pattern and up to 303 GPH for the Model # EF6010SS 1/2″ No Drip External Mix Narrow Angle Flat Fan Pattern.

When making a selection, there are 5 common considerations to take into account:

  1. How much liquid flow do I need?
  2. Is the liquid pressurized?
  3. What is the viscosity of the liquid?
  4. How wide of an area needs to be treated?
  5. What type of spray pattern fits the application?

If you have an application requiring a fine mist of atomized liquid or if you’d like to discuss another product or application, contact one of our application engineers for assistance.

No Drip Internal Mix Deflected Fan and 360° Hollow Circular Pattern Atomizing Nozzles

EXAIR offers a wide variety of  Atomizing Spray Nozzles that can be used to coat, rinse or cool a surface. We manufacture (3) different types – Internal Mix, External Mix, and Siphon Fed – as well as 3 different sizes – 1/8″ NPT, 1/4″ NPT and 1/2″ NPT – all in 303ss construction, rated up to 400°F.

Today, I would like to focus on 2 specific Atomizing Nozzles – our No Drip Internal Mix Deflected Fan Nozzle and our Internal Mix 360° Hollow Circular Pattern Nozzle.

Model AD2010SS – No Drip Internal Mix Deflected Flat Fan Atomizing Nozzle, 6.9 GPH, 1/4″ NPT

The No Drip Internal Mix Deflected Fan Atomizing Nozzle produces a flat fan of atomized liquid at a right angle to the nozzle’s orientation and is designed for use in pressured fed applications where the liquid doesn’t need to be controlled independently from the pressurized air. This nozzle is the perfect choice in processes where mounting space is limited like spraying solvent on conveyed parts inside a small chamber or coating the inside of an enclosure. The patented No Drip feature positively stops the liquid flow when the supply air pressure drops below 30 PSIG, eliminating the need for any additional valves or supply lines.  This is especially beneficial in applications using expensive fluids or where drips can ruin a finished product. This nozzle is available with 1/4″ NPT inlets and flows as high as 6.9 gallons per hour.

 

Internal Mix 360° Hollow Circular Pattern – designed to spray evenly, away from the nozzle in all directions.

Our Internal Mix 360° Hollow Circular Pattern Atomizing Nozzles produce a circular spray pattern, the ideal solution when trying to coat the inside of ductwork or where a broad mist of atomized liquid is necessary, like dust suppression or humidification. Available in 1/4″ NPT with flows as high as 14.7 GPH and spray diameters up to 53″ in diameter  depending on air and liquid supply pressures. With the 1/2″ NPT, we can achieve up to 150 GPH with a spray diameter up to 156″. Our  standard Atomizing Nozzles also feature an adjustment valve to provide control of the flow rate, making them easy to adapt to a specific requirement.

If you have an application requiring a fine mist of atomized liquid, please contact one of our application engineers and let us know how we can help in making the best product selection to fit your need.

Maintenance Free And Proud Of It

Caller: Do you sell rebuild kits?
Me: Yes, but…why?

This is a WAY oversimplified summary of the start of a popular conversation that an EXAIR Application Engineer might have with a caller looking to restore a particular product to proper operation. Truth is, most of our products have no moving parts, and if you supply them with clean, dry air, they’ll run maintenance free, darn near indefinitely. We’ve documented this in specific cases regarding a Reversible Drum Vac from 1999, a Vortex Tube from 1987, and a Cold Gun from 1985.

Product & year of manufacture, from top left: Reversible Drum Vac (1999,) Cold Gun (1985,) Vortex Tube (1987.) All still performing within factory specifications.
Product & year of manufacture, from top left: Reversible Drum Vac (1999,) Cold Gun (1985,) Vortex Tube (1987.) All still performing within factory specifications.

Caller: So…DO you sell rebuild kits?
Me: Yes, but…only when necessary.

It’s important to note that none of the products mentioned above needed any parts replaced to return to service. Sometimes, a good cleaning is all that’s required. We can help you with a video tutorial if you want to know how to restore a Reversible Drum Vac, an Air Knife, or an Atomizing Spray Nozzle, for instance.  And we’re making new videos all the time for product maintenance, operation, tips & tricks, etc.

Caller (again): So…you DO sell rebuild kits?
Me: Yes, of course!  I mean, who wouldn’t sell rebuild kits for their products?

Take our Safety Air Guns, for example. We offer Service Kits, if the trigger and/or internal valve of a Soft Grip or Heavy Duty Safety Air Gun starts to wear or leak, it’s super easy to replace. We’ve also got replacement springs for the “fail shut” feature of the ball valve of a Super Blast Safety Air Gun. Just about anything else that could be wrong with a Safety Air Gun’s performance can be addressed by cleaning the nozzle.

We also recently added Rebuild Kits for our Atomizing Spray Nozzles to inventory. These contain all of the seals (and moving parts, for the No-Drip models) to restore an EXAIR Spray Nozzle to rated performance.

Keep your EXAIR Atomizing Spray Nozzle (left) in perfect working order with a simple & inexpensive Rebuilt Kit (right of the nozzle.) Contact an Application Engineer to select the one for your product.

For other products, we can also provide replacement gaskets & seals for the Reversible Drum Vac & Chip Trapper products, O-rings for the Line Vacs, Chip Vacs, and Heavy Duty Dry Vacs, new elements for Filter Separators & Oil Removal Filters…just to name a few.

Bottom line: if your EXAIR product isn’t performing the way it used to, give me a call.  It will be my pleasure to help you get it working like new, so that you can continue to get the most out of it.

A Lot Can Happen In Five Years

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.

Patented Nozzle is a 2016 Flow Control Magazine Innovation Awards Nominee!

No Drip Atomizing Nozzle
No Drip Atomizing Nozzle

The patented (no longer patent pending) EXAIR No-Drip Atomizing Spray Nozzles have been nominated and are a finalist in the Flow Control 2016 Innovation Awards.  The No Drip Atomizing Nozzles are just a portion of the entire Liquid Atomizing Nozzle products that EXAIR Offers.   The No-Drip’s patented liquid shut off valve design eliminates the need for a separate pilot air line to positively shut off liquid flow ensuring there are no drips or excess flow from the nozzle.  These are ideal when dealing with fine surface finishes, costly liquids, or intermittent spraying needs.  The nozzles are offered in both pressure fed liquid and siphon fed liquid versions.

For the pressure fed version, the nozzle will require both compressed air and a pressurized liquid source. Both pressures can be adjusted independently giving a large spectrum of adjustment to fine tune the spray pattern and droplet sizes.  The siphon fed nozzles can draw liquid up to 36″ vertically or be gravity fed up to 18″ overhead.  This makes installation quick and easy when a pressurized liquid source, or liquid pump is not at hand.

The No-Drip Atomizing Spray Nozzles have also proven themselves in many applications, you can even read about a few of them here on our blog, links below.

2013 Innovation Awards
2013 Innovation Awards

 

Some of the reasons the EXAIR No-Drip Atomizing Nozzles were selected for these applications are the patented no-drip valve, their ability to atomize liquids to a range of 22-71 micron droplet size, the ability to fit into a tight space as well as the many spray pattern options.   These features have ranked the nozzles as a finalist in Flow Control’s 2016 Innovation Awards.

We are very grateful if you choose to vote for our nozzle at the link below. Please vote.

The Only Constant Around Here Is Growth

But if there’s a second constant around here, it’s excellence. And if there was a third, it was this guy…right up until the day he retired:

Joe Panfalone, Application Engineer extraordinaire, holding our bounty of product awards from 2013. He's retired since, but he's not...EVER...forgotten.
Joe Panfalone, Application Engineer extraordinaire, holding our bounty of product awards from 2013. He’s retired since, but he’s not…EVER…forgotten.

Another thing we don’t want to forget – in fact, I’m writing this as a reminder to YOU, dear reader, is that EXAIR products are up for ANOTHER four Plant Engineering Product of the Year Awards this year.  If you haven’t familiarized yourself with this year’s entries yet, there are some VERY cool products to choose from, and I highly encourage you to check them out(Disclaimer: I was an engineer BEFORE I came to EXAIR, and as such, I fully recognize the value that our esteemed colleagues bring to the table with THEIR entries, but I remain convinced that OURS are the clear winners here, as I’m sure you will too.)

Voting ends this Friday, January 8th 2016, so please hurry.  We’re honored to have gotten the nod in four categories this year:

ETC Dual CC SystemsAutomation and Controls: The competition is pretty stiff in this category…I’m sure you’ll recognize the names of some major players.  But, considering the wide range of applications, the potential cost savings by regulating the use of compressed air, and the convenience afforded by the ETC Dual Cabinet Cooler Systems, it’s a real contender.

HLRDVEnvironmental Health: With the ability to vacuum heavier tramp oils, thicker sludge, more viscous fluids, and “in the floor” cisterns, the High Lift Reversible Drum Vac makes fluid transfer and spill cleanup quick & easy.  They’re in stock for 30, 55, or 110 gallon drums. If you want a drum dolly, additional vacuum tools, or even the drum itself, check out our Deluxe and Premium Kits.  With all due respect to the other entries, it’s the clear winner in this category.

Compressed Air1006ss: This has been a long-awaited addition to our already broad selection of engineered air nozzles: the Back Blow Air Nozzles, available in two sizes, can handle blowing out pipe, tube, etc. with inside diameters from 7/8″ to 16″.  You can get one installed on one of our Safety Air Guns, and they’re available with Chip Shields, and extension pipes up to 6 feet in length.  This is the most innovative product being introduced in this category this year, for sure.

Fluid HandlingNo Drip Atomizing Nozzle: The patented design of the EXAIR No-Drip Atomizing Spray Nozzle offers a stand-alone nozzle capable of controlling liquid flow without requiring a liquid control solenoid.  When the air supply pressure is shut off, so is the liquid flow…just like that.

This feature is available on any of our Atomizing Spray Nozzles.  For safety, efficiency, cleanliness, it can’t be beat.

Remember, voting ends this Friday.  I know there are some great products to choose from, but all of us at EXAIR would genuinely appreciate your vote for our products.  Of course, if you ever have any questions about how these – or any of our Intelligent Compressed Air Products – can make life easier, give me a call.
