I don’t think you can compare CFM across fan types. The utility fans like the Lasko and Wahoo Headwind direct air in a narrow column. The Lasko linked a few posts up is “only” 340 CFM, but it all comes directly at me. A few mm difference in where the base is directed can mean the difference between the air hitting you or not.
A large pedestal fan like this one below has a CFM rating of 4,800 and costs about the same as the Lasko. 4,800!!! That’s 14 times more powerful than the Lasko, I bet if I was using it I would get blown off my bike! Well, no, that’s highly unlikely. The larger fans disperse the air widely, which is great if you’re wanting to give a little puff over a wide area, but we’re not, we want high velocity over a 1 ft square area up to about 3 feet.
