This promotional item, the model 1126 1″ Flat Super Air Nozzle, has a patented shim to blow a 1” wide stream of air to clean surfaces quickly and efficiently and is a $45.00 USD value. For more details on the Promotion, click on the photo/link above. For more information about the Flat Super Air Nozzles, click HERE.

Inexpensive air guns can be purchased just about anywhere- online, via catalogs, and through industrial supply companies. Typical quality is less than ideal – broken triggers, leaky valves – a short lifespan in an industrial setting are merely a few of the issues observed.  Most are loud and inefficient – they just blow large amounts of compressed air, and at noise levels that violate OSHA requirements.  Some may even generate dangerous dead end pressure situations that that can result in serious or fatal injuries if blocked.

EXAIR’s Safety Air Guns have been engineered and designed to eliminate these issues. They are durable for use in industrial situations and comfortable to use for extended periods of time.  With an EXAIR engineered air nozzle, each model provides top performance by entraining large volumes of surrounding air into the air-stream. Operation is assured to be safe along with low compressed air consumption and noise levels.  Due to the design, the airflow that exits the nozzle cannot be blocked, as required by OSHA Standard 29 CPR 1910.242(b).

EXAIR’s Vac-U-Gun: Blowoff or Vacuum with Just One Gun!

Now through the end of May, EXAIR is running a promotion on the Industrial Housekeeping Products that includes a FREE Vac-U-Gun with any purchase of an Industrial Housekeeping Vacuum System. EXAIR’s Vac-U-Gun is a low-cost solution to a wide variety of industrial housekeeping problems. The Vac-U-Gun has a durable die cast construction and no moving parts to replace or wear out.

In addition to being easy to use, the Vac-U-Gun is also more efficient than ordinary blow guns. By injecting a small amount of compressed air through directed nozzles, a vacuum is then produced on one end and a high output flow on the other. The amplified outlet flow through the Vac-U-Gun is 12 times the compressed air consumption of the gun.

The Vac-U-Gun is capable of both vacuuming material, as well as being operated as a blow gun. In vacuum mode, the work surfaces can be easily cleaned by vacuuming the debris away rather than blowing it off of the surface. Rather than simply moving the material around the shop floor, it can be contained and transferred to a waste receptacle using the 10’ vacuum hose, or straight into the filter bag.

vac u gun orientation

Switching from vacuum mode to blow mode can be achieved in just a matter of seconds. To change the Vac-U-Gun from vacuum to blow mode, simply remove the threaded cap and change the orientation of the generator inside. Since the Vac-U-Gun has a large 1-1/4” diameter air outlet, it covers much more surface area in less time compared to traditional air guns. This can help to reduce the time needed for a variety of different blowing, cooling, or drying applications. Due to the nature in which the Vac-U-Gun entrains ambient air, it allows for more force and flow through the gun at a minimal compressed air consumption.

vac u gun kits

The Vac-U-Gun system is available by itself, or in one of three different kits. It can be used with or without the 10’ (3m) vacuum hose or the filter bag. Various vacuum accessories are included in the kits to accommodate a variety of different materials and applications. If you’re looking for a versatile gun that can help boost productivity in a number of applications within your facility, look no further than the Vac-U-Gun.

The Case For The EXAIR Super Air Wipe

If you’ve ever used an air gun to blow something off, you’re familiar with the cleaning ability of compressed air.  If you can get the whole object blown off from where you’re standing, there really is no substitute…but what if you need to get to the other side…or sides?

Even if your product is not on fire, you probably wouldn’t want to “limbo” under it with an air gun…

This is where the EXAIR Super Air Wipe comes in…they allow you to blow a continuous, uniform 360° air stream, all around your product.  Consider their benefits:

*Sizes: the Super Air Wipe’s compact ring design means it won’t take up a lot of room; you just need a few inches, in any direction, to install one.  We stock them in eleven sizes, from 11″, all the way down to our brand-new 3/8″ diameter.

*Durability:  All EXAIR Super Air Wipes are assembled with stainless steel shims and hardware.  Models up to 4″ come with a rugged, stainless steel wire braided hose, connecting the two halves for compressed air supply.

The aluminum Super Air Wipe is available in 11 sizes; the stainless steel Super Air Wipe comes in 5 sizes…all from stock.

*Ease of installation:  Smaller sizes can be supported by the compressed air supply line, if a pipe is used and threaded into the connector hose’s 1/4 NPT port.  Larger sizes can likewise be adequately supported with pipe to both halves. All models have a bolt circle of 1/4″-20 tapped holes for more permanent and rigid mounting.  The split ring design is another key feature:

Simply open the two halves, and clamp them around your product…no threading!

*Corrosion resistance: Depending on the environment in which the Super Air Wipe will be installed, we offer them with aluminum (3/8″ – 11″ sizes) or stainless steel (3/8″ – 4″ sizes) bodies.

*Temperature rating: Aluminum Super Air Wipes are good to 400°F (204°C) and stainless steel models are good to 800°F (427°C.)

*Range of operation: We install a 0.002″ thick shim in all stock Super Air Wipes; this is suitable for a wide range of typical industrial/commercial blow off applications…a Pressure Regulator can then be used to “dial in” the air flow precisely to meet specific needs.  If a job calls for higher force & flow, additional 0.002″ shims can be installed.  Shim Sets come with the Super Air Wipe Kits, or individual shims can be ordered separately.

*Performance: Before the Super Air Wipe, a ring of nozzles was commonly used.  In fact, they still are, but we’re trying to fix that, at every opportunity we come across.  Problem with those is, it’s hard to get an even air flow all around, which leads to inconsistent blow off.  They can also be loud & inefficient, as we’ve found in numerous Efficiency Lab tests and Case Studies, like this one…

These wasteful and loud modular plastic tube blow offs…
…were replaced with EXAIR Super Air Wipes. 24 such replacements netted the customer an annual compressed air cost savings of over $13,000.00.

…and this one…

Implementing a Super Air Wipe salvaged a $30,000 job for this customer. Click on the picture to read all about it in our Case Study Library (registration required.)

Do you have a challenging blow off application that you need help with?  Call us to find out how an EXAIR Super Air Wipe (or another one of our Intelligent Compressed Air Products) can be a simple, quick & easy solution.

Safety Air Guns – True Cost of Ownership

There are many inexpensive, cheaply made air guns out on the market.  If evaluated solely on purchase price, the decision of what air gun to buy seems obvious.  Only when you consider all the cost of ownership and operation, does the best direction become apparent.

A popular thumb lever operated air gun, readily available online has a base purchase price of $6.11.  The List price of the EXAIR model 1210 Soft Grip Safety Air Gun is $81.00. Wow- big difference you think, I am surely not going to spend that kind of money on a simple air gun.  Let’s take a look of the true cost of ownership for each of the guns.

IMG_6967
Thumb Operated Air Gun
1210
EXAIR Model 1210 Soft Grip Safety Air Gun

We tested both the model 1210 and the other gun utilizing our Efficiency Lab service. We tested at 80 PSIG of supply pressure and measured and recorded air consumption, force and sound levels. Results of this testing is shown below.

Capture

From the test data, the other gun is able to provide 9% more force, but at a cost of 35% greater compressed air consumption, 5.64 SCFM more, along with an 18 dBA sound level increase (a sound level where hearing protection is needed, an additional cost to be incurred.)

If we examine the compressed air consumption, we can calculate the yearly compressed air usage, considering 4 hour per day of operation, 5 days per week, for 50 weeks out of the year.

Capture

 

A general rule of thumb for industry is that 1000 SCF of compressed air costs $0.25 to produce.Capture

As you can see, after 1 year of operation the Soft Grip Safety Air Gun has already paid for itself with compressed air savings, not to mention significantly reduced sound levels, well within the OSHA Standard 29 CFR – 1910(a) for Maximum Allowable Noise Exposure. To read more about the OSHA Standard, see this EXAIR blog. An EXAIR Safety Air Gun will continue to bring you benefits after this ROI period, and includes many other feature you do not receive with the cheap air gun.

You get the EXAIR 5 Year Built to Last Warranty which covers defects in workmanship and materials.  EXAIR’s safety air guns lead the way in standards and certification – we meet or exceed relevant OSHA standards, carry the CE mark and utilize a conflict mineral free supply chain.  We offer (5) types of Safety Air Guns, all offering ergonomic, comfortable, lightweight operation.

Safety Air Guns are also available with optional Chip Shields and Extensions (in lengths of 6″ to 6′) along with many different nozzle sizes (2.5 SCFM to 460 SCFM of air flow) and a variety of materials (Zinc Aluminum alloy, Stainless Steel, brass and PEEK plastic) to allow the configuration of the best air gun for your application.  EXAIR Safety Air Guns are great for use in applications ranging from light dust removal from delicate circuit boards to large scale, long distance, wide area blow off, cooling and drying applications and everything in between.

Proper Supply Line Size And Fittings Provide Peak Performance

Many times when we provide the air consumption of an EXAIR product, we get a response like…. “I’ve got plenty of pressure, we run at around 100 PSIG”. While having the correct pressure available is important, it doesn’t make up for the volume requirement or SCFM (Standard Cubic Feet per Minute) needed to maintain that pressure. We commonly reference trying to supply water to a fire hose with a garden hose, it is the same principle, in regards to compressed air.

When looking to maintain an efficient compressed air system, it’s important that you use properly sized supply lines and fittings to  support the air demand (SCFM) of the point-of-use device. The smaller the ID and the longer the length of run, it becomes more difficult for the air to travel through the system. Undersized supply lines or piping can sometimes be the biggest culprit in a compressed air system as they can lead to severe pressure drops or the loss of pressure from the compressor to the end use product.

Take for example our 18″ Super Air Knife. A 18″ Super Air Knife will consume 52.2 SCFM at 80 PSIG. We recommend using 1/2″ Schedule 40 pipe up to 10′ or 3/4″ pipe up to 50′. The reason you need to increase the pipe size after 10′ of run is that 1/2″ pipe can flow close to 100 SCFM up to 10′ but for a 50′ length it can only flow 42 SCFM. On the other hand, 3/4″ pipe is able to flow 100 SCFM up to 50′ so this will allow you to carry the volume needed to the inlet of the knife, without losing pressure through the line.

Pipe size chart for the Super Air Knife

We also explain how performance can be negatively affected by improper plumbing in the following short video:

 

Another problem area is using restrictive fittings, like quick disconnects. While this may be useful with common everyday pneumatic tools, like an impact wrench or nail gun, they can severely limit the volumetric flow to a device requiring more air , like a longer length air knife.

1/4″ Quick Connect

For example, looking at the above 1/4″ quick disconnect, the ID of the fitting is much smaller than the NPT connection size. In this case, it is measuring close to .192″. If you were using a device like our Super Air Knife that features 1/4″ FNPT inlets, even though you are providing the correct thread size, the small inside diameter of the quick disconnect causes too much of a restriction for the volume (SCFM) required to properly support the knife, resulting in a pressure drop through the line, reducing the overall performance.

If you have any questions about compressed air applications or supply lines, please contact one of our application engineers for assistance.
