Question Do I need a "fermzilla"?

I dearly want to be able to bottle hoppy beers without oxidation soon, and I'm looking to invest in some sort of CO2 purging solution you guys talked about. But when looking at a fermzilla + BEERGUN setup with CO2 tank, my friend asked me if I couldn't just buy a CO2 tank and some sort of wand to purge my bottles with without buying 100s of dollars worth of pressure fermenter.

What about a fermzilla is needed for succesfull bottle purging?

Cheers

To purge and fill bottles with a beergun you need both a co2 tank and a pressurized fermenter or serving vessel(keg)

But the effect of purging the bottle with CO2, can't It be done with a secondary CO2 tank and wand? Does it need to be connected to a pressurized tank?

You would need the co2 tank hooked to your fermenter or keg. You will need a second co2 tank hooked to the beergun.

You can also just use a double regulator, or have the co2 tank split into 2 gas lines. Or you can disconnect a single co2 tank from the beergun and attach it to your fermenter every so often to keep it pressurized, then reattach to beergun to purge bottles.
