| sb0 | whitequark, can that thing reach good vacuum? | 03:12 |
|---|---|---|
| sb0 | and is it really oil free? | 03:12 |
| whitequark | sb0: it will be more than sufficient as a rough pump | 03:14 |
| whitequark | i actually considered getting one, but it's too unwieldy, if slightly cheaper used | 03:15 |
| whitequark | (not this one, the one I could pick up locally for $50) | 03:15 |
| 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. | 03:16 |
| whitequark | yes, I know. | 03:16 |
| sb0 | is that thing better that a wet rotary vane pump? | 03:16 |
| whitequark | I'm fairly certain. if it will have any oil, it would only be in bearings. | 03:17 |
| whitequark | and I don't think bearings will outgas at roughing pressure much | 03:17 |
| whitequark | I mean, a (vacuum scroll pump) compressor is a (A/C freon scroll pump) compressor | 03:18 |
| whitequark | they don't really differ much in design | 03:18 |
| whitequark | for bonus points, the A/C ones tend to be much quieter | 03:18 |
| DocScrutinizer51 | congrats for surviving xmess, and a successfull 2015 to everybody! Live long and prosper | 18:56 |
| larsc | too early | 19:03 |
| astr | same for you. | 19:20 |
