Not All Compressed Air Guns Are The Same

If you work in an industrial plant or manufacturing environment, chances are you use some type of compressed air gun for cleaning parts, work areas, etc. Many air guns purchased through large industrial suppliers are a common choice due to the cost of the gun but as the saying goes – “you get what you pay for”. These types of guns may be cheap to purchase but they are also made cheap and have parts that can break easily, like the trigger or nozzle. In many cases, the nozzles on these guns are also in violation of OSHA requirements, producing dangerous discharge pressures and loud noise levels, which can lead to costly fines or potentially deadly injuries.

EXAIR offers 5 different styles of Safety Air Guns that not only eliminate these concerns, but also provide a more efficient operation, which can reduce energy costs. All of our Safety Air Guns are fitted with our engineered Air Nozzles  which meet OSHA Standard 1910.242(b) for 30 PSI dead end pressure, as they provide a relief or safe path for the air to exit if the nozzle were to be blocked or pressed against an operator’s body so the exiting air pressure will never reach 30 PSIG. They are also engineered to entrain surrounding air across the profile of the nozzle, which produces a smoother airflow, ultimately reducing wind shear, resulting in much lower sound levels, meeting OSHA Standard 29 CFR 1910.95(a).

 

 

The Precision Safety Air Gun body is made of a durable high impact, glass reinforced nylon, providing for a lightweight, ergonomic operation. These guns feature a curved extension, ideal for delivering a powerful stream of air in hard to reach areas, like clearing debris from drilled holes. All of the nozzles used with these units are either 316ss construction for durable, corrosion resistance or PEEK plastic for non-marring applications. The air inlet is 1/4 FNPT and there is a convenient hanger available for safe storage.

 

 

 

Our NEW VariBlast Compact Safety Air Guns are ideal for light to medium duty processes, featuring a variable flow trigger to achieve different force levels ranging from 2.0 ounces up to 1 pound, depending on the nozzle. The body is cast aluminum and there are (2) 1/4 FNPT air inlets available, 1 on the bottom and 1 on the back of the gun, as well as a storage hanger, for easy installation. Nozzles are available in zinc aluminum alloy, 303ss, 316ss and PEEK plastic. These guns are available with aluminum extensions from 6″ up to 72″.

 

 

The Soft Grip Safety Air Guns are commonly used in long-term use applications as they feature a comfortable grip and long trigger which helps to reduce hand and finger fatigue. The cast aluminum construction is well suited for more rugged environments and again, features a hanger hook. These guns can be fitted with aluminum, stainless steel or PEEK plastic to meet the demands of a variety of applications and are available with 6″ – 72″ aluminum extensions for extra reach or Flexible Stay Set Hoses , allowing the user to aim the airflow to a specific target area. The air inlets for these guns are going to be 1/4 FNPT.

 

 

 

EXAIR’s Heavy Duty Safety Air Guns deliver higher force and flows than other air guns, as these units feature a 3/8 FNPT air inlet, which maximizes the compressed air flow to the engineered Super Air Nozzle. Like the Soft Grip, the durable cast aluminum body is designed for use in tough industrial processes, and the ergonomic and comfortable trigger are ideal for hours of use. Aluminum extension are available, again in lengths from 6″ up to 72″, but feature a larger diameter for optimal flow and superior durability.

 

The Precision, VariBlast, Soft Grip and Heavy Duty Safety Air Guns are ALL available with an optional, polycarbonate Chip Shield to protect personnel from flying chips and debris, further meeting OSHA Standard 1910.242(b) for the safe use of compressed air.

 

Lastly we offer our Super Blast Safety Air Guns. The Super Blast Safety Air Guns are ideal for wide area blowoff, cooling or drying a part, as well as long distances. They feature a comfortable foam grip and spring loaded valve that will shut off the airflow if the gun is dropped. These units use our larger Super Air Nozzles and Super Air Nozzle Clusters, providing forces levels from 3.2 lbs. up to 23 lbs. Depending on which nozzle is fitted on the assembly, air inlets will range from 3/8 FNPT up to 1-1/4 FNPT. Aluminum extensions are available in 36″ or 72″ lengths.

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.

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:

IMG_5789

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.

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).
