Where to buy CO2
Which CO2 bottle do I need?
For our CO2 traps, we recommend using a 10 kg gas bottle. However, you could also use 5, 6, or 20 kg if you prefer.
Where can I get the CO2 bottles?
The gas bottles are not included in the contents.
The gas bottles can be acquired or rented at drink retailers or bottle depots for a deposit. A door-to-door delivery service may also be available in some locations.
The following sites offer competitive renting prices:
- Roberts Oxygen
- National distributor of food grade CO2: Air Gas
Air Gas has over 900 locations throughout the US.
Other CO2 suppliers are mostly regional, Welding and Brewing suppliers.
How long does a gas bottle last?
How often you need to change the gas bottle depends on:
- what size you use and
- which release rate of CO2 you use
If CO2 is released continually over 24 hours with our recommended release rate of 0.5 kg/day, a 10kg CO2 tank will last about 20 days.
