CFM for Commercial Kitchen Exhaust Ventilation

On average, a range hood fan must move at a minimum of 100 CFM of air for about every 12 inches of the stove width. This actually determines that in case you have a stove that is 30 inches wide then you will need a range hood with a fan that rotates for at least 250 CFM of air.

Other than these particular instructions that will be given to you at different sections, you should always keep this thing in mind that you should never use commas. For instance, you will have to write 20000 and not 20,000. Feel free to always use decimal points if required. All sections do not have to be filled, but within a section fill in all the required information, otherwise, you are going to get the wrong results.

In order to find the fan that is needed for your size kitchen, multiply the number of cubic feet in the room by the number of air exchanges (15), then divide it by the number of minutes in an hour that is (60).
