Air Guns to Meet & Exceed OSHA Standards

The Soft Grip Safety Air Gun is a blow gun which is in stock for immediate shipping and has a durable cast aluminum body that is suited for rugged industrial use.  The ergonomic design has a large trigger and a soft, comfortable grip for easy operation and keeps the hand in a comfortable position for extended periods of use. A convenient hook hanger allows for easy storage when not in use.  Aluminum Extensions (up to 72″ long) and Stay Set Hoses (up to 36″ long ) can be fitted, providing access to hard-to-reach places. Chip Shields are available for most models, protecting operators from flying debris, helping to meet an important part of OSHA’s requirements for the safe use of compressed air, OSHA Standard 1910.242(b).

The Soft Grip Safety Air Gun can be configured with dozens of nozzle options, air consumption as low as 2.5 SCFM @ 80 PSIG of supply pressure and up to 60 SCFM if needed.  Nozzle materials include Zinc Aluminum alloy, Stainless Steel, and PEEK thermoplastic as well as forward blowing or back blow nozzle options.

Using any of EXAIR’s Safety Air Guns with an Engineered Air Nozzle will provide safe and efficient use of compressed air, reduce energy costs, and eliminate harmful dead-end pressures (again, helping to comply with the OSHA standard for safe use of compressed air) when compared to standard commercial air blow guns, open pipes, and other homemade attempts to use compressed air efficiently and effectively.

When outfitted with EXAIR’s engineered air nozzles, the Soft Grip Safety Air Gun is a powerful ally to reduce personnel noise exposure and protect them from noise-induced hearing loss. This is another important safety feature complying with OSHA’s standard 29 CFR-1910.95(a). Lowering the ambient noise level also helps to improve operator satisfaction of their working environment.

The Soft Grip Safety Air Gun can be configured to meet applications from delicate blowoff of electronic circuit boards to large chip removal in metal cutting operations, and everything in between.

Industrial Air Gun Accessories For Safety And Convenience

The words “safety” and “convenience” are rarely synonymous. Many times, in fact, they are seemingly at odds with one other:

  • Decades of data absolutely prove the importance of wearing a seat belt in a motor vehicle. In the dead of winter, when I’m wearing a heavy coat and gloves, it can be cumbersome to pull that belt across me and fasten it without removing those gloves that are protecting my sensitive hands from the brutal cold. I do it anyway, and so should you.
  • I don’t own a boat, but I have friends that do, and I find it hard to pass up an invitation to spend a nice summer afternoon water skiing, tubing, or just cruising down the river. Life vests on a hot sunny day are perhaps just as cumbersome as seat belts. No matter how good you can swim, though, there’s a big difference between jumping in the water for a refreshing dip and being thrown into the water after a collision with an unseen object. If you’re unconscious, or even just disoriented, that vest will save your life.
  • If you work in an area where you’re supposed to wear safety glasses (even if they fog up) or ear plugs (actually, if they’re uncomfortable, you have the wrong ones…or you’re using them wrong), they’re a miniscule inconvenience compared to losing your sight or your hearing.

Notice I said “seemingly at odds” above, because safety doesn’t HAVE to be inconvenient. I could trade my old bulky insulated gloves for a newer pair made of thinner material that still have decent insulation. People who boat regularly will have properly sized life vests (instead of one-size-fits-most) with snap buckles (instead of pull straps). There are a number of different styles of safety glasses and anti-fogging treatments for the lenses, for long term use in most any environment. Likewise for hearing protection – whether you like the headset-style that covers the ears, or plugs that insert into your ear canals, there are comfortable designs, and some neat technology that cancels harmful sound frequencies so you can even carry on a conversation, even in a loud environment.

EXAIR Corporation has a long history of adding convenience to compressed air use, while remaining well within the confines of safety (that’s something we don’t cut corners on in our products, operations, or company culture) and efficiency. We’ve got accessories, add-ons, tools, etc., for most of our product lines. It’s quite prevalent in our Safety Air Guns product line, and for good reason – there are a number of areas where some flexibility regarding the use of handheld tools not only add convenience, but also contribute even further to their safe use. Consider:

  • Reach. When blowoff needs to happen inside, behind, under, or over an obstruction, extensions are available for any EXAIR Safety Air Gun, so operators can keep their hands free of the obstruction, especially if it’s hot, sharp (or otherwise potentially harmful) or just dirty or wet.
  • Cleanliness. While they’re usually specified to comply with OSHA regulations regarding proper chip guarding while using compressed air for cleaning, Chip Shields also prevent the nuisance of getting yourself dirty or wet from blown off debris. They’re available on all our compressed Air Blow Guns except for the Super Blast models.
  • Reach, part 2. A particularly nifty little option on the Soft Grip Safety Air Guns is the ability to use a Stay Set Hose (as opposed to a Rigid Extension) for extra reach. Let’s say you have to get back to, and behind, an obstruction for blowoff. Simply bend the end of the Stay Set Hose to the angle required, and you’re in business! They come in lengths from 6″ to 36″ long.
  • Stubborn debris. Among the new products that EXAIR has introduced over the past few years, this one is my personal favorite: the Soft Grip Super Air Scraper. We took our 2″ Flat Super Air Nozzle and put a steel scraper blade on it, which assists the air flow by scraping (as the name implies) caulk, gaskets, sealants, tape, paint, etc., off the surface, as the air flow blows it away! It’s the perfect “one-two punch” for applications like these.
In addition to a variety of engineered Air Nozzles, you can customize your EXAIR Safety Air Gun with Chip Shields, Extensions, Stay Set Hoses, etc., to meet the particular needs of a specific application.

If you already have serviceable air guns that operators are used to and comfortable with (first law of human nature is “change is bad,” right?), all of our Super Air Nozzles have NPT threads…you may only be an adapter away from installing them on your existing devices. Speaking of adapters, we also stock a number of the “usual suspects” – an EXAIR Application Engineer can help you determine what your air guns’ existing threads are.

Thumb guns are convenient and inexpensive. Ones with cross drilled nozzles (left) are compliant with the first part of OSHA 1910.242(b). Fitting one with an EXAIR Chip Shield (center) makes it compliant with the second part. A Model 1102 Mini Super Air Nozzle (right) makes it quiet & efficient.

EXAIR Corporation offers a broad selection of quiet, safe, and efficient compressed air products, and one of the most comprehensive selections of handheld solutions in the industry. Whatever your need for a Safety Air Gun is, we most likely have you covered. Call me; let’s talk.

Turn the Pressure Down, Save Operation Costs

I recently recommended to a customer to turn their air pressure down on their system as low as their process would allow. Meaning regulate the pressure so you have enough to complete the operations needed but find that happy medium where your compressor isn’t working as hard to build those high pressures for no reason!

Compressed air is an amazing tool to have, and when used properly it can be more efficient that other non compressed air tools that run off electricity. How ever its pretty common to see compressed air systems running at their max just because.

Lowering the air system pressure reduces the compressor power consumption by about 1% for every two psi of lower pressure. Lowering the pressure also makes any unregulated operations reduce consumption by almost 1% for every one psi of pressure reduction. Not to mention the extra savings if your compressor system can turn down the compressor power because of the reduced flow and possibly shut off compressors that are no longer needed!

The best pressure at which to set your system is the level where your production can operate efficiently and effectively without waste: There is no right pressure—it depends on your operations and tools. You may have 90 to 100 psig at the compressor, but at the production machine, where the actual work is being done, you could have only 65 to 70 psig. In some cases, it may be even lower due to pressure drops in undersized piping, filters, regulators. The goal is to lower compressor discharge pressure without affecting the the operations at the end of the line.

Having artificially high plant-pressure can help you deal with surges in compressed air demand that might occasionally cause low-pressure and affect production. The higher pressure acts to store reserve air in the various volumes made up of receivers, pipes and such in your system. However, the higher pressure costs more to produce and makes unregulated end uses consume more air, which is an expensive trade-off. Another option is to make sure you have line pressure regulators at each point of use. This will allow you to regulate the operation to the pressure needed being sure to save compressed air and keep the over all system running more efficient.

You can regulate those point of use lines with a number of EXAIRs Pressure Regulators!

EXAIR offers a range of Pressure Regulators capable of handling air flow of up to 700 SCFM.

If we can help size a regulator, or have any other questions on how EXAIR can help you save compressed air in your system please reach out to me or one of our other Application Engineers!

6 Important Factors when Choosing a Safety Air Gun

If you look at operating costs alone, compressed air can be just about the most inefficient method there is for cleaning parts. If you just look at the risks, it’s potentially very dangerous too. Don’t even get me started on the insufferable noise it can make.

For cleaning parts, most folks are familiar with the use of an air gun. You can find the simplest of these in many industrial settings: a valve (often in the form of a handheld trigger device) fitted with a nozzle of some sort (often in the form of an open ended tube, pipe, or fitting to focus or direct the air flow). These have all three of the “downsides” I opened this blog with. Of course, these concerns can be mitigated to a high degree by using the right tool for the job. That’s where engineered products like EXAIR Safety Air Guns come in. Let’s look at how we can address these three “downsides”:

Efficiency: This is all about compressed air consumption. In the simplest of air guns mentioned above, consumption is only limited by the passages in the valve (or trigger) and the discharge fitting…and those limits are usually negligible. Modifying the ends (see examples below) to focus the air flow usually has minimal effect, because you’re not appreciably changing the total cross sectional area of the discharge opening:

Here are a few modified thumb trigger air guns that were sent in for Efficiency Lab testing. Left to right, compressed air consumption at 80psig supply pressure was 34.2 SCFM, 30.9 SCFM, and 28.2 SCFM. For comparison (more on this later,) EXAIR Model 1210 Soft Grip Safety Air Gun uses only 14 SCFM and generates a very similar flow pattern.

Safety: Remember learning about kinetic and potential energy in grade school? Well, when you compress air to 100psig, fitting all that air into a much smaller space creates a TREMENDOUS amount of potential energy:

The block on the left represents a cubic foot of air at atmospheric pressure. The one on the right represents how much space the first one takes up when compressed to 100psig. The energy imparted by this process HAS to be handled with care.

One problem with the thumb guns above is, if you were to jam into the palm of your hand and pull the trigger, a large component of that potential energy (pressure) turns into kinetic energy (force)…more than enough to break the skin and cause a potentially fatal condition known as an air embolism. In the United States, OSHA (Occupational Safety and Health Administration) regulates compressed air devices used for cleaning purposes. All EXAIR Safety Air Guns comply with Standard 1910.242(b) by providing a relief path to ensure that it cannot be dead ended, and thus never create over 30psi measurable at the outlet)

EXAIR Super Air Nozzles cannot be dead ended, ensuring the outlet pressure won’t reach OSHA limits, regardless of supply pressure.

Noise: Another problem is, another component is turned into sound pressure…discharging air from a direct opening is quite loud. OSHA standards address these with limitations on outlet pressure and sound level. All EXAIR Safety Air Guns comply with Standard 1910.242(b), which limits the outlet pressure (by providing a relief path to ensure that it cannot be dead ended, and thus never create over 30psi measurable at the outlet) and all but our largest Super Blast Safety Air Guns comply with Standard 1910.95(a) limits for continuous 8 hour sound level exposure.

Which brings us to the topic of this blog: How exactly did THEY (our customer who used to use the thumb guns above) select the right Safety Air Gun, and how can we apply that to getting the right Safety Air Gun for YOU?

These steps aren’t all-inclusive, and they don’t necessarily need to be followed in order, but if you call an EXAIR Application Engineer about selecting a Safety Air Gun, here’s what we’re gonna talk about:

Ergonomics: We offer five distinctive styles of Safety Air Guns:

From small part cleaning by hand, to wide area blowoff, and all points in between, EXAIR has a Safety Air Gun for most any application.

Our thumb gun user (as I alluded to above) chose the Model 1210 Soft Grip Safety Air Guns (top right). They had a number of typical industrial applications where the operators had the parts or surfaces to be blown off right in front of them. They liked the integral storage hook and rubberized hand grip, but the VariBlast Compact (top middle) or Heavy Duty Safety Air Guns (bottom left) were also considered. The VariBlast Precision (top left) and Super Blast Safety Air Guns (bottom right) were too focused or more powerful, respectively, than needed.

Airflow pattern: Honestly, I could make a good case for this being the first consideration. Selection of any blowoff product – be it an Air Nozzle, Air Amplifier, Air Knife, Air Wipe, etc., will largely depend on the size and shape of the airflow.

variety of airflow patterns…and effective distances…are available from EXAIR’s comprehensive line of Super Air Nozzle products.

Application specific concerns: Everything we’ve discussed so far has involved aiming the blow off stream away from the operator, in the direction the device is aimed. In addition to wide variety of engineered Air Nozzles, EXAIR offers a number of options for these products:

Atto Back Blow Nozzles can blow out recesses or holes as small as 1/4″ in diameter.
Scrape off, and blow away, stubborn debris with the Model 1244-48 Soft Grip Super Air Scraper.

If you’re looking for a portable, hand-held compressed air blow off product that’s quiet, safe, and efficient, look no further than EXAIR Corporation’s extensive line of Safety Air Guns. If you’d like to find out more, give me a call.
