Read Answers for Can Fans High Output

i need more air in my furnace room would a 4 inch can fan be good for that -roger

Hey Roger, With all fans you want to buy a fan that will have the CFM's to preform the task at hand. How many cubic feet is the room you are trying to ventilate? Height (X) Width (X) Length= Cubic feet. Lets say for easy math its 1,000 (CF). You want to exhaust a room 100% in three minutes or less. So for that room we would be talking about a fan rated at 333 cfm (Cubic, Feet, per Minute). Figure out the Cubic Feet of your room, divide it by three and that is the CFM rating of the fan you should get. Hope this help. Cheers, Bart -Greners Staff
