Re: CO2 FAQ



Time to eat crow again........ ;-)

Using the ARO model number that Lyndle quoted (ARO 127112-820), I continued
my yahoo searching and found several on-line catalogues from companies that
sell ARO regulators. I found several similar models, but not an exact match.
I returned to Ingersoll-Rand's web site and looked in the "literature"
section of the ARO division. There are several PDF files for regulators, one
of which (http://www.irco.com/aro/downloads/R271XX.PDF) might describe the
regulator Lyndle mentioned. It is available with an output close to that
mentioned by Lyndle.

However, in the PDF file describing the regulator, I notice the following
caution:
---------
WARNING - Use with industrial compressed air systems only. Do not use with
bottled gas products or fluids. Misapplications can result in component
failure.
---------

Is this something that we should be concerned with when designing/using a
CO2 system??? The CO2 we use is a bottled gas......
