UPDATE: I've uploaded photos of the scrolls, which appear to be in good condition. Anest Iwata DVSL-100B oil-free scroll vacuum pump. Really a lovely little pump.
If you haven't used Anest Iwata products before, they're very much top of the line - well-built, quiet and overall a pleasure. Anest Iwata was the first company to commercialize the scroll vacuum pump, and they make rebranded pumps for Leybold and several other companies. The 100B has an air flush circuit to get rid of moisture in high-humidity locations.They're air-cooled and do not require a nitrogen purge. I tested this pump down to roughly 600 mtorr with o-rings that could probably stand to be replaced.
This pump should still do well as a roughing pump for quite a while, especially considering that its replacement model is only good to 375 mtorr. Ultimate Pressure (nominal, from factory) 150 mtorr (20 Pa).Weight 41 lbs (18.5 kg). Rough Dimensions 15" x 10" x 9.
