"Well," I would tell him, "I could do that, but it would be moisture-laden, dusty air, and it would only be enough air for a few breaths at the surface, and no breaths underwater because the water pressure squeezing my chest would be stronger than the air pressure coming from the tank."

That's awesome! One little thing i would have liked to hear is the actual part that ensures the air pressure is the same as the environmental pressure, rather than the 10 bars. As soon as the lever gets pulled, the 10 bar air flows inside the second stage. That air presses the diaphram away from the lever. As soon as the pressure inside the second stage is the same as the environemntal pressure, the diaphram is pushed so far out, that it is in its initial state and is no longer holding the lever down, airflow stops, and thus the pressure won't increase any further.

When you walked away from the tank (stepped out of the frame), I felt it in my gut and instictively tried to jump to hold the tank. I'm trained to pretty much treat tanks like potential bombs. Nice explanation of the regulators, this is a video I can refer my students to if they ask about it. Newer/'high end' models also have a venturi system built into them, but I've never been able to tell the difference when breathing. Then again, the adjustable breathing resistance knobs never feel like they do anything for me either, so I guess I'm just really not picky with regulators. I do notice that they free flow really easily when sensitive, so there's that.

@seanlotz95813 жыл бұрын
To your 'diffuser' question, a few manufacturers have actually tried this by incorporating a somewhat honeycombed set of plastic openings where the bubbles come out of the exhaust tee. It does seem to help with shrinking the size of the bubbles, & lessening the associated noise as well. I think it's a great idea, and it disappoints me that so many modern manufacturers resist progressing with ideas like this... (but reliability has seen improvements, with even cheap regulators being surprisingly good these days)

@BlueWorldplus3 жыл бұрын
The design of regulators is that if they fail, they usually fail by leaking--meaning air comes out when it's not supposed to. And that kind of failure might be annoying but it does not result in a failure to breathe. In 30 years of diving, I have never seen a regulator fail in such a way that you can't continue to use it to get to the surface. People do carry an additional second stage regulator (commonly referred to as an octopus, for reasons I have never understood). Generally however, this redundant second stage would be used for a buddy who ran out of air.

@BlueWorldplus2 жыл бұрын
Yes, that's a valid test. The other thing you get with a dodgy mushroom valve is water seepage when you inhale underwater. So if you are getting a "wet breathing" reg, that's the first culprit to check. Very often there is nothing actually wrong with the valve, it just has some mold or something growing on it that prevents it from making a good seal.
