Description of CO2 cylinder
CO₂ bottle 2 kg with filling
RAL gray with rotary valve
with TÜV approval (approx. 9.5-10 years)
Diameter: 108 mm
Total length: 497 mm
Weight incl. filling: approx. 7 kg
CO2 E 290 – Carbon dioxide for your food
Please note: The cylinders are filled and sealed by the manufacturer using a measuring device. However, the weight should also be checked.
TARE weight + contents = total weight
As this question comes up frequently, here is a brief clarification:
The bottles also come with a sticker.
This indicates the shelf life of the contents (CO²).
The TÜV stamp is stamped on and is valid for 10 years. Example 4/2017 = TÜV until 4/2027
These are owned bottles and not exchangeable bottles
You should inquire about refills locally, e.g., at a beverage wholesaler or aquarium/pet supply store.

### Adjustable carbonation intensity
The carbonation intensity can be individually adjusted by setting the working pressure between 0 and a maximum of 4 bar. A lower pressure results in less carbon dioxide in the water. **QUOOKER recommends a maximum CO2 pressure of 400 kPa (4 bar)** to prevent overloading the system.
#### Important information:
- **CO2 cylinders must always be connected upright.**
- Although CO2 is a relatively harmless gas, high concentrations in enclosed spaces can cause health problems such as circulatory failure. Sufficient **air circulation** is therefore essential to ensure that the CO2 concentration in the air you breathe **does not exceed 3% by volume**.
- In closed rooms, the **use of a carbon dioxide detector** (gas warning system) is recommended.
#### Safety precautions for indoor use:
To ensure safe use in private areas, the minimum size of the room in which CO2 gas is used without additional protective measures should not be less than:
- **15 m² for 2 kg CO2**
- **45 m² for 6 kg CO2**
- **75 m² for 10 kg CO2**
If the calculated volume lies between two sizes, always choose the smaller size as a reference.
