If the CO2 is captured in a keg at 12PSI I'm guessing that will not be enough pressure to bottle 5-10 gallons of beer sitting in the fermenter after lagering at 8 PSI (example for the sake of illustration).
I wonder if there is any kind of an air compressor that could be hooked to a little keg that receives CO2 from your fermenter through a one way valve and periodically pumps it into another keg which you use as the pressure source to run a beer gun.
The Blichmann beer gun's manual specifies 15-20 PSI for the CO2 input for the purging function, but I wonder how many PSI minimum needs to be in the tank for it to supply 15 PSI to a regulator. Of course at the same time we would have to supply 8 PSI (in the arbitrary example) to the fermenter to keep it topped off.
Another thought would be to run a beer gun from a pump instead of regulating the fermenter, that way you only need CO2 to purge with, or trying to do it without a regulator, last time I racked at like 3 PSI into a bottling bucket it sorta felt like the pump was unnecessary (Spike CF10 with racking arm). Even then, if you set your PRV to 12-15 PSI and therefore got about that much in your keg I sorta have doubts about whether that would be good for purging.
If the CO2 is from the same batch it shouldn't mess with your flavor right? Or would it "go bad"?
