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!
