Ventilation is determined by the amount of area you are trying to exchange air in and really has nothing to do with the amount gasses your torch burns. For a quick calculation of CFM's needed to clear a room in a certain amount of time you can use this site;

My bench is closed in on both sides, back, and the top and bottom so I'm not concerned with replacing the air in the whole room, just the work spaces, as that is where the torch's are.
And by the way the Phantom is a great torch, more torch than what is needed to make beads. You can make 2 to 2 1/2inch marbles pretty easily with it. Once you learn how to adjust it you can get a small little flame for detail work or a large flame for melting in dot stacks on 2 inch marbles, or anything in between.
Another excellent site on ventilation is this one;
https://mikeaurelius.wordpress.com/ventilation-primer/
Mike has been designing and teaching about ventilation systems, manufacturing Aura Lens flame working glasses, and helping glass blowers for many years. He actually knows what he is talking about more so than I do. But then again I know a bit myself.
And by the way a phantom doesn't burn "a hell of a lot of fuel". That is unless you want to compare it to a minor or similar small torch.
If you want to learn more I suggest continue reading on this site and go to this site also.
www.talkglass.com/forum
There is a lot of great info there by knowledgeable folks that have been doing mainly boro glass for years and will help you get started right.
Mind you there are always some folks that feel they know something when they really don't, but this is the internet.
Just my 2 cents, take it with a grain of salt.
