USUN boosters

[rjack321]

I'm trying to figure out which USUN booster I need to pair with my compressor, I'll drive it off my air bank. I've got it narrowed down to the XB30, the XBD30 and the GBT15/40, and I'm sure the 15/40 will do everything I can dream but I've had people suggest that it might be overkill. What I'm trying to do:
1. Filling 3L rebreather oxygen bottles, I'm sure any of the boosters would be fine for this.
2. Topping up OC deco bottles of 100% and 50%. I'm unsure if the XB30 has enough flow to work with AL80s, all the notes talk about it working great with 7L and smaller.
3. Scavenging trimix from my OC doubles. I know the GBT15/40 can take them down to 100psi rather than 500psi, but I'm not sure if I'm going to actually care.

Does anyone have experiences here?

Only #1 is a plausible use of air bank gas. For #2 and 3 you will want a dedicated shop booster, as large and as high pressure as possible. 120psi minimum and 150psi is better

Are you just filling for yourself? Any reason to want to go air driven?
