What CO2 is used for
Our carbon dioxide (CO2) is used for draught beer and soft-drink dispense, aquariums and hydroponics, welding shielding gas (mixed) and food packaging. Whatever the application, you get the same rent-free terms and quick cylinder exchange.
- Draught dispense — pushing beer, lager, cider and soft drinks through cellar and bar lines.
- Aquatics & hydroponics — CO2 enrichment for planted aquariums and grow rooms.
- Welding — as part of an argon/CO2 mix for MIG on mild steel, or pure CO2 as a budget shielding gas.
- Food & drink — beverage carbonation and food packaging.
CO2 sizes
- 6.35kg — smaller cellars, home bars and aquatics.
- 10kg — a mid step for steadier throughput.
- 34kg trade — high-volume venues that want fewer changeovers.
CO2 sizes & exchange
CO2 comes in 6.35kg, 10kg and large 34kg trade cylinders. Smaller bars and home setups tend to run a 6.35kg, while higher-volume cellars choose the 34kg to cut changeover frequency.
Every size is rent-free — pay for the gas plus a one-off refundable deposit, then exchange your empty for a full cylinder of the same size on the spot.

Frequently asked questions
Can I refill my own CO2 cylinder?
Adams Gas operates on an exchange basis — you bring an empty Adams Gas CO2 cylinder and swap it for a full one. We do not refill third-party or non-approved cylinders for safety and certification reasons.
What size CO2 cylinder do I need for a pub?
Most cellars run a 6.35kg or larger CO2 cylinder depending on throughput. Higher-volume venues choose the 34kg trade size to cut changeover frequency.
Is the cylinder rent-free?
Yes. Adams Gas cylinders are rent-free with no ongoing hire charges — you only pay for the gas refill/exchange and a one-off refundable deposit.
