M4 Back Blow Nozzle Dries Inside Of Small Cylinders

A few weeks ago I received an inquiry from a customer who was looking to blow water off the inside of a closed cylinder after a zinc bonding process. There are 8 parts that are placed on a manifold which is then inverted and sent into their current blow off setup that includes small open tubes that get inserted into each cylinder to try and blow out the water. This setup worked a little but the issue they were experiencing was the airflow coming out of the tubes was blowing the water up, which caused it to collect in the “bowl” of the cylinder and as the blow off tubes were removed, the water would start to leak back out and down the inside walls again. After the current blow off, the parts are manually removed and inspected for moisture content. If the parts are found to be outside of their tolerances, an operator uses a modified blow gun fitted with a small tube to manually complete the process.

After discussing the particulars with the customer, their needs were two-fold – first they needed a nozzle that wouldn’t push the air toward the end of the tube but something that would direct the air “backwards” so as they placed the nozzle inside, they could hopefully “pull” the liquid out as the nozzle is removed. The second concern was the cylinder had a small 0.390″ diameter opening so the nozzle would need to be small and powerful enough to be able to fit inside the part, while still providing effective blowoff.

Once again, EXAIR offered the perfect solution, our Model # 1004SS M4 Back Blow Nozzle. The Back Blow Air Nozzle produces an even, 360° airflow that is directed away from the end of the nozzle. At only 0.20″ in diameter, The Model # 1004SS is the ideal choice for treating the inside diameter of small hose, pipe, bores (up to 1″) or in this case, small enough to fit inside the opening of the cylinder. With this design blowing the air back away from the end, the water wouldn’t get trapped in the bowl but rather would allow the inside walls of the cylinder to be wiped clean while directing the liquid toward the opening so the water can be removed.

In addition to the Model # 1004SS M4, we also offer our Model # 1006SS 1/4″ NPT Back Blow Nozzle for use with 7/8″ to 4″ ID’s, as well as our Model # 1008SS 1″ NPT unit for treating large ID”s up to 16″, for larger scale applications

The Model 1006SS cleans metal shavings from inside a pipe.

EXAIR’s Back Blow Nozzle is the perfect choice for cleaning or drying the ID of part or tube.

Back Blow Nozzle Improves Cylinder Testing Process

Drying rig used to clean fire extinguishers after pressure testing

A few weeks ago I made a video showing how the Back Blow Nozzle operates.  The video is helpful to illustrate the process of pipe cleaning, but this isn’t the only application for a Back Blow Nozzle.

I was recently contacted by a testing facility which provides inspection services for fire extinguishers.  As part of the inspection process, the empty fire extinguishers are pressure tested by filling the empty cylinders with water and raising the pressure to a specific PSI.  After passing this test, they are emptied, turned upside-down, and fed over a drying rig.  The drying rig (shown above) is a crude setup, using a brass tube with a few drilled holes.

In order to sufficiently dry the cylinders with this setup, they needed to be placed on the drying rig for long periods of time, sometimes for several minutes.  This long cycle time was a waste of compressed air, and the end user wanted to find a better, more efficient solution.

Model 1006SS, 1/4″ NPT Back Blow Nozzle

The solution was to replace the drilled pipe with a ¼” NPT Back Blow Nozzle, model 1006SS.  The angled orifices of this engineered nozzle force the air, and water in this case, from the cylinder.  There is no longer a need to leave the cylinders on the drying rig for several minutes – drying is now accomplished in a fraction of the initial time.  And, in addition to the improved cycle time, the engineered nozzle is able to reduce sound level from the drying rig.

Back Blow Nozzles can be used in a variety of applications.  If you have a process which you think could benefit from an engineered nozzle solution and you’d like to discuss with someone, contact an EXAIR Application Engineer.

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 Back Blow Nozzle Nominated For Plant Engineering’s Product Of The Year

Here at EXAIR we are always working to develop new technology to meet your demands and solve the problems of our customer’s industrial applications.

Back on June 8th, 2015 we released our NEW Back Blow Air Nozzle. The Back Blow Air Nozzle provides a 360° high velocity, airflow that is directed away from the nozzle making it perfect for blowing out the inside diameter of pipe, bores, threads, or other critical internal diameters. The unique design eliminates the safety concern of blowing the particulate out of the end of the tube/pipe or forcing the contaminants further into the pipe, trapping them inside. We offer 2 different sizes, our Model # 1006SS 1/4″ NPT for use with inside pipe diameters ranging from 7/8″ up to 4″ and our Model # 1008SS 1″ NPT for use with I.D. pipes from 2″ up to 16. These nozzles are constructed of 316ss for durability and corrosion resistance.

The Model 1006SS cleans metal shavings from inside a pipe.

The Back Blow Air Nozzle is the perfect choice for cleaning the I.D. of a pipe.

Developing such cutting edge technology, not only helps our customers but in some cases, earns us some much appreciated recognition. This year the Back Blow Air Nozzle has been nominated for Plant Engineering’s Compressed Air Product of the Year for 2015. This award is very meaningful as it is chosen by the reader as a useful new product for solving industrial applications.

Back Blow Nozzles: When Blowing Forward Is Not An Option

Have you ever been in a situation where you need to blow debris or chips out of a pipe or a blind hole?   Maybe it is a pipe you are saw cutting and don’t want to push chips and debris further down the pipe line  You could be trying to clean out a pipe that has debris inside and and can’t push it further down the line because it could damage other system components.  Other customers cleaning out inside diameters of pipe cannot blow all the way out the other side of the pipe due to people being present on that end of the pipe and need to avoid harming them.

The Model 1006SS cleans metal shavings from inside a pipe.

Using Water and Air to Clean or Cool Cylindrical Parts

In the last year EXAIR has released two products that aid in cleaning and cooling cylindrical shapes. The liquid sprayed from our AT1010SS Internal Mix Spray Nozzle creates a 360° Hollow Circular Pattern that is excellent for cleaning the inner diameter of a pipe, a casting, or a bore. The 1006SS Back Blow Nozzle is an air only nozzle that is designed to clean, dry or cool the inside diameter of a hose or tube and also effective cleaning out channel. These products can be used in conjunction to create a more powerful system than either component by itself.

360 degree Internal Mix Hollow Circular Pattern

AT1010SS – 360° Internal Mix Hollow Circular Pattern

The AT1010SS spray nozzle can be used in a variety of applications. As I mentioned above the 360° spray pattern is great for spraying out the inside of a pipe or duct-work. In addition to these applications, the nozzle can be used to cover a wide area with spray patterns up to 53 inches in diameter. This wide spray area can be used for humidification, dust suppression, cooling or sanitizing. The 303 stainless steel construction of the nozzle will hold up to a variety of chemicals and environments.  These nozzles can cover a significant area while using a relatively small amount of air and liquid. The AT2010SS is also available which features EXAIR’s No Drip design (patent pending), which will positively shut off the liquid flow when air pressure is removed. This eliminates unwanted drips which can ruin surfaces and waste expensive liquids. The 360° Circular Hollow spray pattern is a versatile nozzle that covers a variety of applications.

The EXAIR Model 1006SS - Back Blow Nozzle

The EXAIR Model 1006SS – Back Blow Nozzle

The 1006SS back blow nozzle features a number of orifices around the outside of the nozzle which force air back toward the operator and away from the air inlet. In most applications this will be used to pull water, chips, coolant, or debris out of the end of a pipe, channel, or tubing to clean the inner diameter. The Back Nozzles will typically be offered with a chip shield to contain any chips or debris from blowing towards the operator.

These two nozzles used in conjunction would work great to cool, clean, and dry the inside of, say, a welded pipe. The AT1010SS could be used to flush the inside of the pipe with water to cool the weld and blow out and weld slag or grinding dust from preparing the area. The 1006SS could pull out the water or debris from the inside of the pipe. The AT1010SS can be reinserted to spray the inside of the pipe with a rust inhibitor to maintain the quality of the weld until installation.  These nozzles work well together to clean the ID of the channel, tube or hose in your application.

Back At Ya!

This may not be big news as it happens almost every month.  EXAIR is continuing to grow our product line and this time it is something we have never done before.  This new EXAIR Engineered Solution doesn’t blow debris away, instead, it all comes back towards you.   Why would you want this you ask?  What does this new-fangled contraption look like?  Both of those questions will be answered below.

To answer the first question, why would you ever want debris to come back at you?  Well, this isn’t for just blowing any part or area out, this nozzle has been designed for a special purpose – to blow out pipes, tubes, extrusions, and even some blind holes or pockets.   This is ideal when working on a piping system that you may need to clean out and don’t want to push debris further into the system.   It is a quick and easy way to clean out chips from a saw cut operation for tubing or extrusion.  The nozzle could even be used to clean out cylinders or crank shaft openings on engine blocks.

So what is the name of this new nozzle and what does it look like?

What does it look like already!

What does it look like already!

 

The EXAIR Model 1006SS - Back Blow Nozzle

The EXAIR Model 1006SS – Back Blow Nozzle
