Not sure if this is the place to ask this question but I am thinking about using a scuba tank for a portable air tank. I was wondering if anyone has done this? A scuba tank can hold up to 3300psi. I would use about 2500psi and you can buy a regulator for the tank to bring the air pressure down so you dont blow your head off. A buddy of mine is into the scuba stuff. And he thinks it would work. I just thought I would ask if it has been done before.
