If hes air cooling the hoods then he can go with a cfm of 500-700. I have a thread on some pretty silent & powerful fans. If hes air cooling the room then he needs to specify the dimensions of the room to get the right cfm.
A typical way of doing this is simple. Say your room is 10 x 10 x 9. This would equal 900 cubic feet. A fan should clean the air within 5 mins so you would devide 900 cf / 5 mins. This would give you a recommended CFM of 180. So you would need a fan with 180 cfm or greater.
