A Beginner's Guide to Pneumatics

[Storcky]

One thing to be aware of, you mentioned using the regulator with the yellow ring because it's easier to adjust. We were told by an inspector at our first event this year that this must be a secondary regulator. The FIRST pneumatics manual backs this up although the wording is not very strong and doesn't really explain why. I've tried researching it a few different times but have been unable to find exactly what the difference is between the two so if anyone does know, I'm curious.
