N2 tank for scba : 2L 200Bar or 8L 150Bar

[moonseeker]

Hello, I found some sources for N2 (4m4z0n), I can either get :
- 150 Bar 8L
or
- 200 Bar 2L

Do you think 2L would be enough for SCBA, knowing that you don't use that much gas in the first place since you use only what you breath.

Id go with the 8L option. The 2L cylinder provides ~26min of continuous flow at 15LPM. This is viable but the 8L cylinder provides a larger saftey net in case you have leaks & other problems or want to conduct tests before CTB'ing...
