Pressurized systems need regulators.
No, the link is a Yeast CO2 system. Much like all the DIY CO2 systems you'll see mentioned(No regulator needed for any DIY CO2). Compressed are the canisters like the helium tanks, however, I believe the big helium tanks you'll see are like 50lbs cyclinders.is the link i posted above a pressurized system? or are those the ones with huge canisters that look like helium tanks. if i make a DIY co 2 do i need a regulator. sry for all the questions. im just not to knowledgeable in this area:help:
