How much cfm do you need for your cooking equipment

What type of ventilation is required for your coking equipment? In order to determine the proper amount of air flow required for your cooking equipment, you must first know how many BTU’s (British thermal units) your gas range emits. Then, with a simple calculation you can determine the amount of CFM (cubic feet per minute) required to properly exhaust your cooktop. For example if your cooktop emits 90,000 BTU’s you would divide 90,000 BTU’s ÷ 100 = 900 CFM. This means that 900 CFM or more would efficiently exhaust your range. For electric and induction cooktops choose a blower with a minimum of 200 CFM per 12 inches of cooktop width. Remember, it’s always a good idea to round up versus down.
