FAQ:

Q: How much psi does a CO2 tank put out?

A: At that temperature, the CO2 puts out only 100 PSI (pounds per square inch). At room temperature (70 degrees), the tank puts out about 850 PSI, and at hot temperatures (around 110 Degrees), the tank can put out a whopping 2000 PSI.

Q: What type of CO2 tank do I need for homebrewing?

A: Most CO2 tanks for homebrewing purposes are made from aluminum, but there are steel tanks available as well, and what type of tank you have will somewhat affect the taste of your beer. Your guide to C02 tanks begins with a simple consideration: a basic understanding of the nature of compressed gases.

Q: How does CO2 expand in a gas tank?

A: CO2 expands rapidly as the tank’s temperature increases, putting more and more pressure on the gas regulator which controls the CO2 output. The CO2 that the tank has been filled with is very cold (between -57 and -78 degrees degrees). At that temperature, the CO2 puts out only 100 PSI (pounds per square inch).

Q: What factors should I consider when buying a CO2 tank?

A: Some of the factors included in your decision should be portability, efficiency, and space considerations. CO2 tanks come in a variety of sizes, usually from 2.5 lb to 20 lbs.
