I don't agree , sorry, he is not talking continuous shop duty here and he does want to use his Jet regulator if he can ( which would probably be fine at 175 psi) especially since it is already out of warranty. I keep my 7.5 / 60 gal. at 135 normally and if I am going to spray paint or blast i crank it up. It really all depends on the amount of volume of air he has available.
