Brian,
You must be planning to have a separate tank for emergency air for breathing, in case of fire etc.

 I'm planning on having
 3 - 300cu ft air cylinders for my ballast supply air. 
 I noticed that if I get them filled with nitrogen it is
 cheaper than getting breathing or industrial air
 !   That is, until I get my own
 compressor. Brian
