    DRAFT BEER FAQS: PRESSURE

    How Many Kegs of Draft Beer Can Be Dispensed from a CO2 Cylinder / Tank?

    Under perfect conditions, it requires about 1/2 lb of CO2 to dispense a 1/2 barrel of draft beer if the keg's pressure is 12-14 lbs. Although leaks may exist and some line cleaning equipment requires pressure from this gas source, keg yield is usually less. Keeping this in mind, the table below lists the approximate number of kegs that can be expected to be dispensed from each size of the CO2 cylinder.

    A CO2 gas cylinder that is properly filled and is at room temperature normally has approximately 800 lbs. pressure reading on the pointer of a regulator’s high-pressure gauge. As CO2 is a gas and expands when heated and contracts when chilled, the gauge reading will vary based on the cylinder's environment. Higher pressure reading for warmer, lower for colder environment.

    Regardless of the environment and the pointer’s reading, it will not change until the liquid CO2 in the cylinder depletes. Once gone, the pointer begins to drop from the original reading signifying that the tank only has gas pressure and is almost empty. To prevent downtime, at this time, the cylinder should be replaced with a full one.
