Been a while, advise wanted

LOL, if I wasn't a dummy and used to much air pressure to clean it, I wouldn't have busted a fan blade in the first place...

True, I probably shouldn't be blasting mine with 80psi.

I turned my compressor down to approx 50 PSI and still broke a blade, so yea, you might want to rethink your sandblasting.
