Hey there. Was wondering if anyone has experience with these AI Vacs? Would I be better off with a rebuilt Edwards or buying this new?
Thanks to the community here, I value everyone’s opinion.

Get an Edwards or leybold or Alcatel
I’m trying out the 5.3 cfm on my rotos. And have a buddy who ran a 11.3 cfm on a 10 liter and was sitting around 900 micron. So ittl work on distillation just not that well. Imagine it will work just fine for my roto
The cfm rate at deep vacuum is not half as good as the recommended brands
@spdking gave a nice explanation about this
For 10liter spd you should really try the 4 cfm per liter equation
To stAy below 100 micron
I mean the crv 24 kept my 12L full bore at 300 microns. So not sure about his equatio. It’s 28 cfm I believe. Gotta take a lot of his stuff with a grain of salt. He made a comment today that a 50L roto should be doing 50L an hour of recovery… which is like 12 gallons an hour… which I’ve never heard of anyone getting even kind of close to that
treu but he is right on this one
Which Edwards would you run on a 12L? The 28?
Interesting. I’ll have to try that on some of my clients short paths. Now that I got my beaker WFE I’m never touching one with a ten foot pole again lol
The 40
But I run a trivac 65 on my 12 with diffusion
What micron are you gettin to? Or is it more a speed of run thing?
I can do a whole main body run in. The 30 micron range but one could even go lower it s the amount of energie you throw at the mantel it that makes that diffrance
Spd is beyond 5 liters not very efficient
But I must say that if that new summit rig can distill those water clear terps a whole new world opens up
Diffusion is a speed of run deu to a steady vac level kinda thing
Sure @spdking can explain in depth
Interesting. I’m rly moving away from spd consultations anyways. But I’ll pass that info along
another good function of spd with diffusion is fractionating of cannabinoids CBN in my case
It s easier to keep them in tales than on a wiper
Thanks everyone. I’m going with the rebuilt Edwards 30. Dudes giving a 90 day warranty, pulls better than factory spec $2000. Can’t complain about that price.
Do you have any pics of this wiper?
Sounds badass
30 micron with a diffusion pump, seems kinda high. Im usually below 20 with a leybold d25b. Ive never used a diffusion we always used turbo molecular on the wipe films and would start getting thc at around 137-140c
It s on a 12 liter spd
That makes sense lol my bad
