For working in remote locations, where power is unavailable or where sound must be held to a minimum, this is the way to go. A CO2 tank is lighter and easier to carry around than a compressor. It will also power other compressed air tools. Carbon Dioxide/CO2 tanks are available through your local Welding Supply outlets and come in 50, 20, 10 and 5 pound sizes. The pound rating applies to the weight of liquid CO2 contained in the tank. The weight of the tank should be engraved on its side.

Plastics make it more efficient... consumption is only 1 CFM at 45 PSI, making Turbo Carver II, the only instrument that will operate effectively on both compressed air and bottled CO2. A CO2 tank is initially less expensive than an air compressor and is much easier to haul around. CO2 does not require electricity and is totally quiet, allowing you to work in remote locations or places where power is not available.
