This 20 lb. CO2 tank with siphon tube ships empty and must be filled locally at a welding supply company, homebrew shop, or gas retailer before use. The siphon tube inside the tank draws liquid CO2 from the bottom of the cylinder rather than gas from the top — important for applications that require liquid CO2 delivery and for maximizing the usable gas per fill.
A 20 lb. CO2 tank is the standard size for commercial draft beer systems, soda dispensing, and other commercial CO2 applications. Sized for practical portability and refill logistics while providing enough capacity for extended operation between fills.
A 20 lb. CO2 tank is the standard capacity for commercial draft beer systems, restaurant soda dispensing, and other commercial CO2 applications that require more gas volume than small cylinders can provide. This tank includes a siphon tube — an internal tube that draws from the bottom of the cylinder — which is important for applications that require liquid CO2 extraction rather than gaseous CO2 from the top of the tank.
The tank ships empty by law — pressurized gas cylinders cannot be shipped filled via standard commercial carriers. Fill the tank locally at a welding supply company, homebrew shop, beverage gas supplier, or fire equipment retailer before use. Most commercial CO2 filling locations can fill a 20 lb. tank in minutes.
At 20 lbs., this tank provides meaningful capacity for commercial draft systems without the weight and handling challenges of larger 50 lb. cylinders. It's a practical balance of capacity and manageability for draft beer setups, soda systems, and other dispensing applications.
The standard CGA-320 valve connection is compatible with virtually all commercial CO2 regulators and dispensing equipment, making this tank a plug-and-play addition to any existing CO2 system that uses standard commercial components.
