nice, potential source eh?
from what i understand, for compressors on LOB and at diveshops they have some kind of moisture remover, oil/dirt filter. hence the importance of a good, open location when pressurizing the scuba tanks. you might need to check what is the air quality and oxygen/other gases content your sectore has - if it is regular or modified.
if all ok then definitely worth considering your own scuba tank. if know how to blend, even better to make nitrox
