2014-12-26 03:12 <sb0> whitequark, can that thing reach good vacuum?
2014-12-26 03:12 <sb0> and is it really oil free?
2014-12-26 03:14 <whitequark> sb0: it will be more than sufficient as a rough pump
2014-12-26 03:15 <whitequark> i actually considered getting one, but it's too unwieldy, if slightly cheaper used
2014-12-26 03:15 <whitequark> (not this one, the one I could pick up locally for $50)

2014-12-26 03:16 <sb0> the main advantage of vacuum scroll pumps is there's no oil in the scroll, and so no oil vapor contaminating the turbopump, chamber etc.
2014-12-26 03:16 <whitequark> yes, I know.
2014-12-26 03:16 <sb0> is that thing better that a wet rotary vane pump?
2014-12-26 03:17 <whitequark> I'm fairly certain. if it will have any oil, it would only be in bearings.
2014-12-26 03:17 <whitequark> and I don't think bearings will outgas at roughing pressure much
2014-12-26 03:18 <whitequark> I mean, a (vacuum scroll pump) compressor is a (A/C freon scroll pump) compressor
2014-12-26 03:18 <whitequark> they don't really differ much in design
2014-12-26 03:18 <whitequark> for bonus points, the A/C ones tend to be much quieter
