Chip Shields, OSHA, And You

Safety is a key part of our culture at EXAIR Corporation.  We have regularly scheduled, all-hands required, safety training on a number of topics.  Our Order Entry team can likely tell you as much about our lockout/tagout procedures as our Machinists can.  Nobody even thinks about entering The Shop without safety glasses, and it’s not just because of the signs.

We pay attention to these…
…so we don’t ever have to use this.

OSHA 1910.242(b) states that “Compressed air shall not be used for cleaning purposes except where reduced to less than 30 p.s.i. and then only with effective chip guarding and personal protective equipment. (emphasis mine)  All EXAIR Intelligent Compressed Air Products are engineered to meet the requirements of the first part (30psi outlet pressure to prevent dead ending…we’ve written about that numerous times, including here, here, and here) and we can also provide pre-installed devices to satisfy the second part:  the EXAIR Chip Shield.

Any EXAIR VariBlast or Heavy Duty Safety Air Gun can come fitted with a Chip Shield, and any Soft Grip Safety Air Gun, except for those with Stay Set Hoses, can as well.  Safety Air Guns with Back Blow Nozzles automatically come with a Chip Shield. The principle is simple: a clear polycarbonate (so you can still see what you’re doing) round disc slips over a short (or long if you want) pipe extension between the gun & the nozzle.  It’s fitted with a rubber grommet so you can position it to where it’s most effective – sometimes that might be closer to the part being blown off; sometimes it may be back a little closer to the operator.

EXAIR Safety Air Guns are available, from stock, with Chip Shields.

If you already have an air gun that’s doing the job, you can easily add an EXAIR Chip Shield to it.  They’re made to fit a wide range of extension diameters, and can even come with the extension if you need it.  We also stock a number of adapter fittings; if you know what threads your air gun has (or if you can send us some photos) we can quickly & easily spec those out for you.

Convenient and inexpensive “thumb guns” 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.
We can provide a Chip Shield for most any device with a threaded fitting. I couldn’t find a way to re-use the non-OSHA-compliant nozzle that came with this gun (thank goodness.)
Another example of a larger air gun fitted with a more powerful cross drill nozzle (left) that can be made totally OSHA compliant with an EXAIR Chip Shield (center.) An EXAIR High Force Super Air Nozzle (right) keeps the power, while reducing noise level and compressed air consumption (right.)

Since 1983, EXAIR Corporation has been manufacturing quiet, safe, and efficient compressed air products for industry (emphasis mine.)  If you have concerns or questions about safety in regard to your compressed air use, call me.

What’s So Great About The VariBlast Compact Safety Air Gun?

Well, for one thing, it’s won ANOTHER award…in addition to the 2018 Plant Engineering Product of the Year (Silver Award, Compressed Air Category) for 2018, it’s now won the 2019 Industrial Safety & Hygiene Reader’s Choice Award.

But we didn’t need awards to tell us how great they are.  EXAIR Corporation has 35 years of continuously improving experience in the design, engineering, and manufacture of quiet, safe, and efficient compressed air products for industry.  The VariBlast Compact Safety Air Guns are just another innovation that’s come to fruition, courtesy of the knowledge, experience, and dedication to quality from our R&D Engineering & Production departments.

Whatever your needs are, EXAIR has a Safety Air Gun for you.

But you don’t have to take OUR word for it: a satisfied customer base has proven the VariBlast Compact Safety Air Gun‘s success:  We offer a 30 Day Unconditional Guarantee on any catalog product.  That means you can put it through its paces for up to a month…if it’s not going to work out, for any reason, we’ll arrange return for full credit.  Of the dozens of VariBlast Safety Air Guns we’ve sold every month for the last two years or so, we have not had one returned.  Not. One.  To which I say: no wonder…check it out:

If you’re looking for an economical, efficient, quiet, variable flow, handheld blow off solution, look no further than the VariBlast Compact Safety Air Gun…just another award winning Intelligent Compressed Air Product, brought to you by EXAIR.  To the readers of Industrial Safety & Hygiene Magazine…thanks for noticing!

Airguns, OSHA, And You

Depending on the context, those may be three words you DON’T want to hear in the same sentence. Case in point…a caller I spoke with recently, who works at a large steel forging plant. During a recent inspection, management was surprised (and disappointed) to find out that, unbeknownst to them, some of their operators had modified some of their compressed air blow off devices.

These modifications left them in violation of both OSHA Standard 1910.242(b) (limit on outlet, or dead end pressure) and 1910.95(a) (limits noise level exposure.)  The OSHA inspector left them with an $8,000.00 fine, and a promise to return with an even higher one if the situation wasn’t corrected.

We discussed the ways their current devices were supplied, the conditions they were operating in, what they were used for…and why the operators had modified them.  Sadly, we found the devices were underperforming due to air supply issues – hoses that were too small in diameter and/or too long, with restrictive quick connect fittings.  And some of their modifications (drilling out the discharge) just exacerbated those problems.

Most of their applications were pretty typical – blowing flash, chips, oil, coolant, etc. from processed metal parts.  Typical enough that a couple of EXAIR Safety Air Guns would allow them to determine what they would need, by taking them around to various stations in the plant and trying them out.

My caller ordered a Model 1210 Soft Grip Safety Air Gun with a Zinc Aluminum Super Air Nozzle (our most popular for typical blow off applications,) and a Model 1260 Soft Grip Safety Air Gun with a High Force 1/2 NPT Zinc Aluminum Super Air Nozzle (the most powerful one available on the Soft Grip Safety Air Gun.)

Here’s Model 1210-6-CS, fitted with a Zinc Aluminum Super Air Nozzle on a 6″ Rigid Extension & Chip Shield.  All EXAIR Safety Air Guns are compliant with OSHA Standard 1910.242(b).

I feel pretty good about the chances of publishing a future blog about the success of this application.  If you want to keep up, I encourage to follow the EXAIR blog – there’s a link to the right to provide your email address – for more on this one, other applications, and a wealth of expert writings on how to get the most out of your compressed air system.

As always, if you’d like to discuss a particular compressed air application and/or product selection, give me a call.

Cold Guns for Spot Cooling or Replacing Mist Systems

By using only a source of compressed air, the Cold Gun and High Power Cold Gun produces a stream of clean, cold air 50°F (28°C) below your compressed air supply temperature. The Cold Gun is very quiet at only 70 dBA and has no moving parts to wear out. Just supply it with clean compressed air and it’s maintenance free.

How does it work, and what are the benefits?

  • The Cold Gun uses compressed air to produce a stream of clean, cold air at 50°F (28°C) below supply air temperature. Generally this will be 20°F-30°F outlet temperature.
  • They use Vortex Tube technology…no moving parts to wear out.

How A Vortex Tube WorksInstant cold air flow with no moving parts!

  • Cold flow and temperature are preset to optimize cooling capability, and are non-adjustable to prevent freeze-up during use.
  • Eliminates the expense of both the purchase & disposal of cutting fluids when replacing expensive mist systems.
  • Removes the potential for health problems associated with breathing mist & vapors, and the safety issue of slipping on a wet floor.

Cold Gun Aircoolant System selection is easy & straightforward…we offer a standard, and a High Power version to meet your specific needs.

Four systems to choose from, to meet most any need.

We also offer Single & Dual Point Hose Kits, to further meet the needs of your application.

One of the best applications I have seen with our cold gun came from a customer in Peru. They are a gold mining operation and they were having trouble with the liquid they were using to cool a saw. Read all about it here!
