general question.

[briant]

Could I use a 3lit pony cylinder filled with a heavy duty car compressor, to say 150psi....
for diving no deeper than 1 or 2 meters to free boat propellors or just for a bit of fun.

would i get say 15 minuts out of it or .........
I would like to hear your views??

thanks Brian

I am going to assume that this is not a spectacular and say that breathing off of a "HD Car Compressor" is a bad idea. You can get into a lot of trouble in 6 feet of water if you are not careful. Get the training/gear or befriend a diver to do the work for you.

Not only because the air is not filtered etc., but you can get into a lot of trouble in 6 feet of water if you are not careful. Get the training/gear or befriend a diver to do the work for you.

What Steve said.. Because we don't want to read about you in the incidents/accidents section.

Could you do it? Yes.

Should you do it? Absolutely not. This is a very bad idea. Air from a regular compressor is not filtered and not acceptable for breathing under pressure, even from a few feet.

Besides the air quality issue, if you really did mean 150 PSI, you would maybe get one breath off the tank. First stage regulators are generally designed to output 135-150 PSI to the second stage. If that's all that's in the tank to start, the first stage cannot deliver anything to the second stage.

I'm sure that's all he meant because those little compressors can't produce much more than that. Providing of course he could even manage to hook one up to a scuba tank.

Just go to Subway and buy one of these instead .

And of course I meant the straw and not the girl.

I reccomend not even trying it to see what you get...

why? well most scuba tanks you breath down to 500psi at the end of the dive.

most home compressors are only capable of 125-150psi with a few that will go to 175psi...


so, when/if you hooked up your scuba tank to the compressor, you'd be dumping 500psi into it's system. It'd basically "backfill" as it's unlikely there is a check valve in place.

Now... I doubt most "home compressors" could handle a 500psi surge. they might have hoses only rated to 350psi for example. So it could damage a hose, compressor cylinder/ring, gauges, etc and could result in something rupturing.

just something to think about....

Still probably better that a Spare Air
