Excerpt from Range Hood Blower Insert - How to Choose The Correct Size :
Range hood blower insert - The second airflow calculation method commonly used in the industry is the 100:1 rule. This rule states that for every 100 Btu's of heat a range generates, the hood blower should move 1cfm of air. Let's say you have a four burner range and each burner produces 12,000 Btu's of heat. You should explore hoods with a minimum of 480 cfm blower rating, then applying the Common Sense Rule as needed. Don't forget to boost the number for island cooking applications.
Range hood blower insert - On the other end of the spectrum, most of us cook with a typical four-burner range. These throw off one-third the amount of heat as the commercial style monsters, but they still must be properly vented in order for your home to remain odor and germ-free. No matter which type of cooking unit you use, the idea is the same - it's all about airflow. The bad news is there is no absolute formula for determining exactly how much air flow is the correct amount. The good news is that two different methods of calculation can be utilized allowing you as the homeowner to dial the number up or down based on how you live and cook.
