Air compressor (South Palm Park, Redwood City)

Ridgid brand twin-stack 4.5 gal, 150 psi, oil-free air compressor. Unit needs maintenance. Motor seems to run just fine, but at least one seal leaks so it currently won't get up to pressure. Model # is OF45150A

I inherited this from a contractor friend intending to fix it up myself, but I have too many other projects, sadly.

PLEASE NOTE: When I got it, I drained the tanks immediately and there was not much condensation. The tanks have no dents or bulges as far as I can tell, but I CANNOT vouch for the integrity of the tanks. The whole unit is also rather heavy. Suffice to say, please only take this on if you know what you are doing. :)
