New aluminum CO2 tanks with valves. Perfect size for a keggerator since it will fit on most compressor shelves and leave more room for kegs.
Due to hazmat reasons, the tank comes empty. See recommended CO2 distributers below;
Fire Systems LLC- 869 N. Nimitz Hwy., Honolulu HI. 96817. (808)537-5994. (Cheapest option. Only fills tanks certain days of the week so tank must be dropped off and pickup up later)
Airgas: 2305 Kamehameha Hwy, Honolulu, HI 96819. (808)842-2142. (Much more expensive option but they will swap your tank out for a full one upon arrival)
