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.

David??

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.
