Ideally, a hood fan should be able to move minimum of 120 CFM air for each 12 inches of stove’s width. That means, if your kitchen has a 32 inches wide stove, you will need a hood equipped with a fan that can move at least 320 CFM of air. 32 inch wide cooking stove X 100 = 320 CFM should be the min vent hood fan size.Click to see full answer. Likewise, people ask, how many CFM should a range hood have?A range hood fan should move a minimum of 100 CFM of air for every 12 inches of stove width. This means that if you have a stove that is 30 inches wide then you need a range hood with a fan that rotates at least 250 CFM of air.Subsequently, question is, is 900 cfm enough for range hood? If your ducting matches your ventilation power, your range hood will do its job properly and quietly. A good rule of thumb for estimating ducting diameter-CFM requirements is: 6” to 8” duct = 400 to 600 CFM. 7” to 10” duct = 700 to 900 CFM. Thereof, is 400 cfm enough for range hood? The basic rule of thumb is that the burners on a gas range/cooktop produce a lot more heat than those on an electric range or cooktop. Then divide by 100 to find the minimum CFM needed for a kitchen with a gas range or cooktop. For example: 40,000 BTU gas range divided by 100 = 400 CFM range hood fan or higher.Is 300 cfm enough for range hood?The HVI recommends taking a stove’s BTU rating and dividing it by 100 to find a minimum level. For example, a stove with a 30,000 BTU rating would require a kitchen hood with a capacity of at least 300 CFM. A kitchen range hood should be able to cycle the air out of the entire kitchen 15 times per hour.
