The Best CFM for a Range Hood A minimum rate of 1 CFM of ventilation per 100 BTU is recommended for high-output cooktops or gas ranges. For instance, a burner with an output of 35,000 BTUs requires a kitchen range hood that provides 350 CFM to clear the air effectively.
.
Accordingly, how do I calculate CFM for kitchen exhaust fans?
To find the size of fan needed, multiply the cubic feet x the # of air exchanges (15) then divide by 60 (minutes in an hour). In our example that would be: 1,800 x 15 = 27,000 divided by 60 = 450. You need 450 CFM minimum for this size of kitchen.
Similarly, how many CFM do I need for a 36 gas cooktop? In the examples used above, if your kitchen has a 30” stove (250 CFM minimum) in a 16' x 16' x 8' room (512 CFM minimum), and a 40,000 BTU gas stove (400 CFM minimum) you would want a fan rated at 512 CFM or higher, plus 100 CFM for the ductwork for a total of 612 CFM or more.
Herein, is 400 CFM range hood enough?
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 350 cfm enough for range hood?
The general rule is that you should have 1 CFM of ventilation per 100 British thermal units (BTU) of a gas range. It's recommended that if you do a lot of cooking that generates strong odors or steam, your hood should be rated for at least 350 CFM.
