What sizes do CO2 tanks come in?

Answered by Michael Blake

When it comes to CO2 tanks, there are various sizes available to suit different needs and applications. The size of the tank you choose will depend on factors such as the amount of CO2 you require, the frequency of use, and the space available for storage. In this answer, I will provide a detailed overview of the different sizes of CO2 tanks commonly found in the market.

1. 5 lb CO2 Tank:
– This is one of the most common sizes used by homebrewers and small-scale establishments.
– It has a diameter of approximately 8 inches and an overall height of around 27.25 inches (including the handle).
– The 5 lb tank is relatively compact and easy to handle, making it suitable for smaller setups or as a backup tank.
– It is DOT approved, meaning it meets the safety standards set by the Department of Transportation.

2. 10 lb CO2 Tank:
– The 10 lb tank is a step up in size and capacity compared to the 5 lb version.
– It generally has a similar diameter of around 8 inches but is taller, measuring approximately 55 inches in overall height.
– This size is often preferred by homebrewers who have a higher demand for CO2 or by small bars and restaurants that require a larger supply.
– The 10 lb tank is still manageable in terms of portability and storage but provides a longer-lasting CO2 supply.

3. 20 lb CO2 Tank:
– As the name suggests, the 20 lb tank offers double the capacity of the 10 lb tank.
– It has a larger diameter, usually around 12 inches, and an overall height of approximately 27.25 inches (with handle).
– The 20 lb tank is commonly used by larger establishments, such as breweries, bars, or restaurants, where a considerable amount of CO2 is consumed regularly.
– While it may be more challenging to handle due to its weight and size, it provides an extended CO2 supply, reducing the frequency of refills.

4. 50 lb CO2 Tank:
– The 50 lb tank is significantly larger and heavier compared to the previous sizes mentioned.
– It has a diameter of approximately 15 inches and an overall height of around 55 inches, making it quite substantial.
– This size is commonly used in industrial applications, such as large-scale breweries or production facilities.
– The 50 lb tank offers a substantial CO2 supply, reducing the need for frequent refills, but it requires proper handling and storage due to its size and weight.

5. Other Sizes:
– In addition to the sizes mentioned above, there are also smaller CO2 tanks available, such as 2.5 lb or even 1 lb tanks.
– These smaller tanks are often used for portable applications or as backup options for emergencies.
– However, they may not be as commonly found as the larger sizes and may require more frequent refills due to their limited capacity.

CO2 tanks come in a range of sizes to accommodate different needs and applications. The choice of tank size will depend on factors such as the required CO2 supply, frequency of use, and available storage space. It's essential to consider the specific requirements of your or dispensing setup to determine the most suitable CO2 tank size for your needs.
