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

<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.
<whitequark> yes, I know.
<sb0> is that thing better that a wet rotary vane pump?
<whitequark> I'm fairly certain. if it will have any oil, it would only be in bearings.
<whitequark> and I don't think bearings will outgas at roughing pressure much
<whitequark> I mean, a (vacuum scroll pump) compressor is a (A/C freon scroll pump) compressor
<whitequark> they don't really differ much in design
<whitequark> for bonus points, the A/C ones tend to be much quieter
