Using a Scuba Tank as a source for Air Tools?

harleyds · #1 Jan 18, 2004, 08:10 PM

So instead of buying an air compressor, coud I setup a hose and use it as the source of compressed air?

I did a bit of research and know that most compressor pump out air at about 125 psi. Since the scuba tank can kick out pressure up to 3000 psi, I would need to do it attach a regulator value to the scuba tank and set the output pressure to 125psi.

Does anyone have any thoughts on this? Theory or practical? I'm asking in a few forums since there doesn't seem to be a forum for Air Tools and I'm hoping some of you guys are experienced with air tools.

Depends on how long you want to run the tools. Figure it this way: An E series scuba tank will hold somewhere around 100 cubic feet of air (I've seen 80 to 135).

Most tools are around 3 to 5 CFM consumption at 90 PSI typically. So the maximum you could get is 20-30 minutes of continuous operation (using 100 CF).

If that works for you, it may be worth a try.
