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)

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
