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.

A Matter of Choice

They say having multiple choices in life is a good thing.  This is also true when it comes to spray nozzles, specifically EXAIR’s atomizing nozzles.

Atomizing nozzles are used to coat, cool, treat, and paint products.  They are also useful for dust mitigation.  EXAIR offers a variety of nozzles, all stainless steel construction for durability and corrosion resistance, that allow for many different spray patterns.   The nozzles only come with two inlet sizes – 1/4NPT and 1/2NPT,  but this is not really the choice-limiting factor it sounds to be.  There are a variety of spray patterns and liquid volume outputs available per size.  The way the air and liquid mix together creates the style of nozzle, they are Internal, External, Siphon Fed, No Drip Internal, No Drip External, and No Drip Siphon Fed.   On top of that, with each mix style and size, there are a large number of spray patterns available.  More choices!

Internal mix nozzles mix a liquid (viscosities up to 300cP) and air, both pressure fed, inside the air cap and produce the finest atomization.  External mix nozzles mix a liquid (viscosities above 300cP) and air, both pressure fed, outside the air cap and allow the liquid and air flows to be adjusted independently.  These nozzles have the highest flow rate and are best used where precise liquid flow is needed.  Siphon Fed nozzles require no liquid pressure.  They can be used with gravity fed liquids (viscosity up to 200cP) or liquids from a siphoned height up to 36in.

The spray patterns available are:  Flat Fan, Deflected Flat Fan, Wide Angle Flat Fan, Narrow Angle Flat Fan, 360° Hollow Circular, Round, Wide Angle Round, and Narrow Angle Round.   Each pattern is different and is tailored for certain usages.  Think of how you use your garden hose.  Many of the patterns and their uses are the same.

Mix and match to meet your needs.  With all the combinations available, you should have no problem finding the perfect pattern for your application.  If you find this plethora of choices to be a bit overwhelming and need assistance, please contact an EXAIR Application Engineer at 1-800-903-9247; we would be happy to assist.

No Drip External Mix Atomizing Nozzle Wins Gold!

It is a very sad day for me at EXAIR… No, I’m not retiring or leaving the company, but today is my last day to write about Plant Engineering Product of the Year Awards …for this year. It has been quite an honor to write about four of our best innovations from the last year over the past weeks.  In case you missed the entries, you can click on the these links to read more about our other 2013 award winners: 316 Stainless Steel Dual Cabinet Coolers, 1 Inch Flat Super Air Nozzle or the Heavy Duty HEPA Vac. nodrip_EF Today’s post is about the No Drip External Mix Atomizing Nozzle, which the readers of the Plant Engineering magazine bestowed the gold award for fluid handling products.  EXAIR’s Liquid Atomizing Nozzles combine the liquid of your choice with compressed air to create a mist of atomized liquid.  The external mix nozzles have the highest liquid flow rate of any of EXAIR’s Liquid Atomizing Nozzles with flow rates up to 60 GPH.  They are a great solution for applications where independent air and liquid control is required.  Additionally, more viscous fluids can be used with the external mixing of the nozzle than either the internal mixing or siphon fed nozzles.  External Mixing Nozzles can be used to atomize liquids up to 800 centipoise. IMG_4031   In addition to the benefits of the external mix atomizing nozzle, this spray nozzle features a valve to positively stop liquid flow, when the compressed air drops below 30 psig. Any time you need to maintain a smooth finish or are spraying an expensive liquid, the no drip function can be invaluable to preventing rework, and ensuring a quality finish on each and every product.  The EXAIR no drip function is patent pending and does not require an additional air line to control the no drip mechanism, simplifying installation and functionality.

It’s as easy as Pi

First off, I would like to say happy Pi Day!  To anyone that has to deal with math every day, or if you are a nerd like myself (and most of the rest of the crew here), then you know your 8th grade math teacher wasn’t lying when she said you’ll use this when your an adult.

So here at EXAIR the wonderful Professor Penurious has graced us all with pie for Pi day.

CoOp-Pi Day1
Wow, there is a TON of pie around here today!!

As I sit here eating a wonderful piece of cherry pie, I am thinking of how I had a customer that was wanting to buy the smallest Atomizing Spray Nozzle we offer, they currently had a model EB1040SS which is our largest External Mix Wide Angle Flat Fan Spray Nozzle.  Due to the versatility of our Liquid Spray Nozzles, instead of buying an entire new nozzle, the customer was able to simply buy just an Air and Liquid Cap.  They were extremely pleased with this solution due to the fact it is merely a trial situation and they aren’t quite sure what they need to achieve their goal.  What they do know is, they can buy multiple caps to interchange on their single body and perform all the testing they wish to determine what will cover their plethora of applications.

If you have any questions or would like see which of our versatile products will fit your application, please let me know.
