I just purchased a 10 gallon 135 max psi portable air tank at Sears, so that I can fill and store it, then have a handy source to fill tires and whatnot when I need to. Product webpage:
Does anyone store air in these tanks for extended periods of time (apparently that is more than one day)? Will I be alright if I drain the tank every month or two and invert it so the moisture can come out? If I can't use it to store compressed air in the garage, I might as well return it.
