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.

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.

Step by Step Guide – Choosing Atomizing Spray Nozzles

EB1040SS

Atomizing spray nozzles atomize fluids to create a fine spray in a variety of patterns for a variety of uses. They are commonly used to mark products, paint or coat, cool, reduce dust, lubricate and clean parts.

With the numerous types of Atomizing Nozzles sold by EXAIR, it can be challenging to shift through all the information. We can help you to narrow down the field to quickly find the correct Atomizing Nozzle for your application.  In a summary, here are the basic questions that need to be answered:

1.) Are you using a pressurized liquid feed?

2.) What is the viscosity of the fluid?

3.) What is the liquid feed rate in gallons per hour (gph) or liters per hour (lph).

4.)  Should I use the No-Drip option?

EXAIR’s flow chart with easy-to-follow steps will walk you through the decision tree and land you at the best Atomizing Spray Nozzle for your application. In answering these simple questions, this chart will guide you to the correct page in our current catalog to get additional information and specifications.    Click on Link below to determine the best nozzle for you.

Atomizing Nozzles have added benefits that can really help

When a customer says the words “Great”, I like to share.

A customer of EXAIR purchased an SR2010SS Atomizing Nozzle for a new project.  He requested the Siphon Feed design so that he did not require a liquid pump (reducing the price of the project).  He attached it to a robot arm to spray water for activating a chemical on a substrate.  With the No Drip Option, he could start/stop the spray with a solenoid valve without getting drips of water into unwanted areas.

In robotics, there is much programing to make sure that the arm moves accurately throughout the space. In this application, the degrees of freedom were tight; so, our customer created a solid mount to attach the Atomizing Spray Nozzle onto the robot arm.  After all the components were assembled for the project, they began preliminary runs.

With a deadline looming around an end-user visitation, they started to run parts through their system. They noticed that the solution required more water to activate.  They contacted EXAIR quickly for help.  I mentioned that if they required more water, they can change the Air and Liquid Cap to a larger size.  The first question that my customer asked was if we had them in stock.  The second question was if changing the air and liquid cap would require removing the Atomizing Nozzle.

The first question was simple. We stock over 10,000 items for same day delivery.  If the order comes in to us before 3 p.m. EST, we can ship same day.  For this customer we were able to overnight the parts.  The second question was answered with a video.  Being that he mounted the body to the robotic arm, the liquid and air cap could be removed easily with wrenches.  In our design of the atomizing nozzles, we can interchange up to 4 different sizes with a quick change to the liquid and air cap onto the same body.  Our customer was quite happy about that.  With little time to program the exact location of the movements, he did not want to remove the Atomizing Nozzle from the arm. We shipped him the 3 other sizes next day, and he was able to find the correct size to use before the visitation of his customer.

If you would like to know more about how our products and services can help you in a pinch, you can contact an Application Engineer at EXAIR at 1-800-903-9247.

Atomizing Spray Nozzles – Categories and Selection

EXAIR Atomizing Nozzles are a reliable way to clean, cool or coat a wide variety of products. Constructed of 303ss, the units are extremely durable, provide superior corrosion resistance and are able to withstand temperature up to 400°F.

No Drip Atomizing Nozzle
EXAIR Atomizing Spray Nozzles atomize fluid in a wide range of spray patterns for various applications.

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

Internal Mix Atomizing Nozzles require a pressurized liquid source and compressed air source and mix the two flows inside the air cap to produce a fine mist of atomized liquid. These nozzles are better suited for applications that don’t require independent control of the air or liquid and are suitable for fluids up to 300 cP.

External Mix Atomizing Nozzles require pressurized liquid and air as well, but allow for independent control to reach higher flow rates with more precise control. With the liquid and air being mixed external to the nozzle, they are able to handle higher viscosity fluids (300+ cP).

Siphon Fed Atomizing Nozzles are the ideal choice for applications without a pressurized liquid source. The liquid can be gravity fed or pulled from a siphon height up to 36″.  Due to the liquid not being pressurized, these nozzles are limited to fluids of 200 cP or less.

With so many choices, it may seem somewhat cumbersome in making the correct selection. To simplify the selection the process, there are 5 common considerations:

  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?

The answers to these questions will allow you to make the best selection to fit your needs. Of course if you still are unsure, you can rest easy as one of our engineers is readily available should you require additional assistance.

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.

EXAIR No-Drip Atomizing Spray Nozzles Recognized By Plant Engineering

AW2030ss559
EXAIR’s patented Model AW2030SS No-Drip Atomizing Spray Nozzle

If you follow our blog, Twitter, or Facebook pages, you may have seen us mentioning recent nominations for Plant Engineering Product of the Year Awards.  2015 will mark the 28th anniversary for this award, in which Plant Engineering readers select the most outstanding new products that help them do their jobs smarter, safer, more efficiently, and more productively.

Considering the pre-qualifiers for such an award, it makes sense that EXAIR products would show up, and show up repeatedly.  This year our No-Drip Atomizing Spray Nozzles have been nominated as a finalist in the Fluid Handling category.

Products in this field are recognized to present improvement potential, allowing users to create a more innovative process.  EXAIR No-Drip Atomizing Spray Nozzles do so by providing effortless integration of controlled liquid spraying.

Compressed air and pressurized (or non-pressurized) liquid are plumbed to the nozzle.  When compressed air is flowing, liquid will flow as well.  When compressed air flow stops, liquid flow stops.  Immediately.

For an end user of this product, this means that a precise volume of a specific liquid can be sprayed in a given time (duty cycle), with complete control before, during, and after nozzle activation.

The key to adding this innovation rests in the proprietary, patented (#9,156,045) design  of EXAIR’s No-Drip Atomizing Spray Nozzles.  Our engineers have worked tirelessly to create a stand-alone nozzle capable of controlling liquid flow without requiring a liquid control solenoid.

The viability of these nozzles has been recognized by Plant Engineering as an innovative new product in 2015.  If you agree and would like to cast a vote for EXAIR, please click here.

We thank you for your readership and, hopefully, for your support in this competition.
