400 CFM is already over kill... 800 CFM is a tremendously powerful
exhaust fan for cooking, most commercial installations are not nearly
so powerful. My little Echo leaf blower is rated at 365 CFM and would
literally blow you away.

My range hood is plenty powerful at 250 CFM, I have it exhausted to
the outdoors, I never run it on High and rarely run it on Medium, Low
is plenty for most cooking. If I ran this on High I'd suck all the
heat/AC out of my house before I could fry a burger.
