QUESTION: Is there a carbon dioxide (CO2) gas tank included?

ANSWER: No CO2 gas tank is included when you purchase the CarboHaler. You have to get the CO2 gas tank yourself. The CO2 quality shall be food or beverage grade, which you can get from any local welding supply store. Most restaurants, gas stations, movie theaters, etc. serving carbonated beverages, also get their CO2 tanks from local suppliers.

In many countries, the local welding suppliers are resellers of CO2 gas tanks from companies like AirLiquide and Linde (former AGA), and you can either purchase or lease the tanks.

In the USA, you can purchase an empty CO2 tank and refill it in many gas stations.

An alternative to a CO2 gas tank is a SodaStream cylinder, which is also not included when purchasing the CarboHaler. A SodaStream cylinder can be purchased in most supermarkets and stores selling household equipment.

There are different standards in different countries. For larger Co2 gas tanks (1, 2, 5 kg and bigger) the standard in America is called: CGA320. In Europe, the Middle East, Oceania, and most of Asia it is called: W21.8-14 (also sometimes referred to Din 477, BS 341, or Standard Type 30). In Japan, the standard is called: JIS B 8246, and in China it is G5/8.

The CarboHaler fits CGA320, W21.8-14, SodaStream Quick Connect, and SodaStream Screw-In.
