I have 20G tank and just got a 55. and I am planning on getting a large compressor for use with air tools.
Has anyone ever run their tanks off the pressure tank of a tool compressor?

I know I would need to put in air filters and traps.. but I am sure the tanks could bubble for some time before the compressor tank got low...

Why would you want to? If it's to "inject oxygen into the water" then you're
not understanding how that works.
