95 x 50 x 160 WHAT? meters? furlongs? fathoms?

I'll take a wild stab, and guess that you meant inches. I always read and heard that you want to exchange your room air once per minute. IF this is so,
lets see how many cubic feet your room is, and go from there. (95/12)ft x (50/12)ft x (160/12)ft = 440 cubic feet. a 440CFM fan would be the MINIMUM necessary to clear a room of that size, once a minute. ducting reduces airflow, and if you are using a carbon filter, that can reduce airflow SIGNIFICANTLY. do remember that heat rises, so it's best if you remove the air from the TOP of the room, or at least, from a level of the room higher than your lights and plant tops.
