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.

Stop Trying To Squeeze More Out Of That Air Gun!

At EXAIR, we LOVE to talk about efficient use of compressed air. That’s why I was thrilled to get a call from an engineer that works for a non-profit firm that promotes energy efficiency to enable businesses in their area improve sustainability, improve the environment, and save money.

They were working with a local company to, among other things, optimize their use of compressed air and wanted to take advantage of our free Efficiency Lab service to get the “before” data on the current blow off devices.

Don't let this happen to your air gun...use an EXAIR Precision Safety Air Gun with a quiet, efficient Super Air Nozzle instead.

Don’t let this happen to your air gun…

Squeeze the trigger on a Model 1410SS Precision Safety Air Gun with Nano Super Air Nozzle instead!

As you can see, they were trying to “squeeze” a little more performance out by, literally, squeezing the tip down.  Thing is, it’s STILL loud and non-compliant with OSHA’s regulations about dead end pressure.  And as far as performance goes, this results in only a slight change in the air flow pattern, with a minimal reduction in compressed air consumption…they’ve changed the geometry of the discharge opening, but not the cross sectional area.  Our Efficiency Lab Test results provide the final answer:

cry for help lab

Efficiency. Saving money. Safety. Sustainability. “Going Green.”   If you’d like to talk about how EXAIR can help you with any…or all…of these things, give me a call.

Keeping the Confusion Out of NPT Pipe Thread Dimensions

I recently had the pleasure of helping a caller solve a problem with a Super Air Nozzle.  He had measured the opening on the outlet of his air gun, and ordered accordingly…unfortunately, he didn’t know that 3/8 NPT did NOT correspond to a 3/8″ diameter of a threaded fitting.  I explained the reason for this, a while back, in a blog entitled “When Is A Half Inch Not A Half Inch? When It’s Half Inch Pipe, Of Course!

The ID of a 1/8 NPT threaded fitting is actually pretty close to 3/8". Here's a dimensions table that I reference often.

The ID of a 1/8 NPT threaded fitting is actually pretty close to 3/8″ (left.) Here’s a link to a dimensions table that I reference often to keep this (on right, a 3/8 NPT nozzle with an 1/8 NPT air gun) from happening.


As you can see, the Model 1105 3/8 NPT Super Air Nozzle will not fit the 0.405″ (not far at all from 3/8″ if measured with a ruler) ID of a 1/8 NPT threaded connection.  No matter; these are all catalog parts that we have plenty of stock on, so, after a brief discussion of pipe thread sizes, he got a Model 1103 1/8 NPT Super Air Nozzle, and it fits just fine:


Model 1103 1/8 NPT (male) Super Air Nozzle installed in a 1/8″ NPT air gun.

Sometimes, an adapter is required for air guns that have straight threads.  Two common sizes for these are 5/8″-28 and 3/4″-32 – and we have adapters for both of these (call for details.) Other adapters are readily commercially available…you may find them in the plumbing aisle of your hardware store, or from a local pipe & pipe fitting supplier.  We’ve seen some air guns, though, that have a proprietary thread that doesn’t match up to anything else…in these cases, we have four types of Safety Air Guns on the shelf, ready to ship.

If you’d like to find out more about using quiet and efficient engineered Super Air Nozzles for your air gun applications, give me a call.

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.

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.

Heavy Duty Safety Air Gun with Extensions up to 72″

Have you ever walked through a facility and looked up?  Most facilities have compressed air lines, electrical conduits, HVAC duct work, lighting ballast, beams, sprinkler systems, etc. located near the ceiling.  Can you imagine the amount of dirt and debris that has been collecting up there?  I received a phone call from a food processing plant.  They knew the necessity in keeping the entire area clean, even above their equipment.  They contacted me for help in trying to remove the dirt and debris from above all the structures near the ceiling.

72" Extension on Heavy Duty Safety Air Gun

72″ Extension on Heavy Duty Safety Air Gun

I suggested the model 1330-72 Heavy Duty Safety Air Gun with a 72” (1829mm) extension.  I also suggested a model 9053 swivel fitting to help angle the 2” (51mm) Flat Super Air Nozzle, installed at the end of the extension.  The customer would use a scissor lift to reach close to the ceiling and with the 72” (1829mm) extension, they could reach all the hard-to-get areas.  The 2” (51mm) Flat Super Air Nozzle would cover a larger area above HVAC duct work and racks of pipe and conduit.  When you add the model 9053 swivel fitting, it will help in directing the force of the compressed air at the top surfaces of your target.  Adding the Heavy Duty Safety Air Gun to this assembly, it makes a very reliable, durable system that can handle the banging and bumping in this application.

Dirt and dust can get everywhere, and EXAIR can help to remove it.  We carry a variety of Safety Air Guns, Super Air Nozzles, and lengths of extension pipes.  If you cannot reach it, give us a call and ask one of our Application Engineers for help.

Safety Air Gun Improves Aluminum Extruding Machining Process

I was doing some work around the house Saturday when I heard my wife shouting out from our laundry room….”Something is wrong with our dryer. This is the 3rd time I’ve restarted it and the clothes are still wet!”. Now having been in this situation before, I knew this meant that the exhaust was probably clogged with lint (again).

See, our laundry room runs parallel to our family room and the exhaust ducting goes up and then across the laundry room, across the family room and then exhausts on the side of the house. (I would like to find the person who thought this was a good idea!). I have thought about re-routing the ducting but the only other option would be to have the exhaust on the front of the house which will “never happen” (per my wife). So I usually end up taking my vacuum and attaching as many extensions as possible to reach as much of the ducting as I can. I have tried a few other methods with no success – like taking my leaf blower and, from the outside of the house, blow the lint back towards the laundry room and into a garbage can. (hint: make SURE your wife is not in the laundry room when attempting this…. They don’t react too well when they get covered in lint!)

This made me think of an application I worked on last week with an aluminum extrusion company. The customer cuts lengths of aluminum siding from 1’ up to 10’ in length and, standing at one end of the material, are using a standard blow gun to try and blow out the chips but are unsuccessful. They reviewed our website but were still unsure what product may fit their needs best, so they gave us a call.

We discussed their application and the customer was able to email pictures. After reviewing the pictures I recommended using one of our Soft Grip Safety Air Guns with our Model # HP1125, 2” Flat High Power Super Air Nozzle and a 72” extension.  The Soft Grip Safety Air Gun is constructed of cast aluminum and includes a hook for hanging in a convenient location. The Model # HP1125, 2” High Power Flat Super Air Nozzle, produces 2.2 lbs. of force @ 80 PSIG and utilizes 37 SCFM with a sound level of 83 dBA. This would also meet or exceed the OSHA standards for safety, per Standard 1910.242(b) for 30 psi dead end pressure, and allowable noise exposure per Standard 29 CFR – 1910.95(a).

Promo’s: Everybody Loves Free Stuff

I have been wanting to purchase a pair of good quality headphones for a while now and with vacation coming next week, I figured now was a good time to make my purchase. I was pretty set on the manufacturer but the tough choice for me was going to be if I wanted a set of earbuds (that fit directly in the ear) or a more traditional pair of “over the ear” headphones. smiley_face_headphones_tshirt-d23545082320430684226v7p_325I tried about 4 different pairs of over the ear units to see what the quality of sound was versus the feel/comfort and was pleasantly surprised but was still leaning towards earbuds. Unfortunately, due to health/cleanliness issues, you aren’t allowed to try on earbuds – which makes sense. So if I was going to go the earbud route I wanted to make sure I had all my questions answered so I decided to get a salesperson to assist me.

We went over features/benefits but this only made me question myself more. Seeing that I was struggling with a decision, the salesperson decided to make my choice a little easier – he mentioned that his store, along with the manufacturer, were offering a free promo but only if I purchased a set of earbuds (at a certain price of course). Due to the sound quality and trusted manufacturer, I was leaning towards a set of earbuds anyway, but hey – who doesn’t love FREE stuff? What they were offering was a free carrying case (not really free since it was already in the box), a free 2 year service agreement ($37 value) and a $25 gift card to their store.

Of course, I took advantage of their offer and made the purchase. After listening to the earbuds while I finished my packing, I couldn’t be happier with my selection.

At EXAIR, we occasionally run promotional offers too. From now through September 30th, 2014, if you purchase one of our Precision Safety Air Guns, Soft Grip Safety Air Guns or our Heavy Duty Safety Air Guns (with or without an Aluminum extension), you will receive a FREE Chip Shield.

Free Chip Shield Promo
The polycarbonate Chip Shield, meeting OSHA 1910-242(b) for compressed air use, offers the operator safe and smart protection from flying debris as well as any splashing. Not to mention that all of our Safety Air Guns incorporate one of our Engineered Super Air Nozzles that meet or exceed the same OSHA standard and reduce air consumption and sound level.

This offer is good for all three models of our Safety Air Guns:

  • Durable, Lightweight, Precision Airflow – The Precision Safety Air Gun is a small ergonomic gun good for light duty cleaning or blowoff and fits well in smaller hands. It also has a strong focused blast of air capable of reaching into tight spaces.
  • Versatile, Industrial Duty, Most Popular – The Soft Grip Safety Air Gun is our most popular gun cast from aluminum with a comfortable four finger trigger to reduce fatigue over long periods. A large variety of air nozzle options provides a solution for light to heavy duty blowoff applications.
  • Powerful, Rugged, Robust – The Heavy Duty Safety Air Gun is the powerhouse you need for the harshest environments and stubborn blowoff applications. It is outfitted with many of our most powerful nozzles to provide the highest force upon your application.

To learn more about this offer, please visit our website or if you have a specific application you would like to discuss, give us a call at 1-800-903-9247.
