The fan must be able to push 400 CFM at the sp.

Why would you want that?  Maybe for a large grow room.  Not for 24x24 flow hood.  Ratings: 1500 CFM @ 1.3" W.G. 500, 1000, and 1250 CFM @ 1" W.G.
I wouldn't run my flow hood at 1500 CFM

He's got another one for sale on eBay. But what the hay. Is anyone filtering their entire house?

It is a little thick, but it would work for a flowhood. Remember, you need 100CFM per cubic foot at the static pressure of the filter(s). You would need a blower that would put out 400CFM at 1.3" plus prefilter. I think that Stamet's "universal" blower, Dayton 4C831, would work if you put a rheostat on it.

You can't use a rheostat on an AC motor. Frequency (50 or 60hz) determines speed on AC applications. A rheostat can only control current flow, and that only controls speed on a DC motor.

In the first paragraph on Nan's page it says, "Be aware that if you're going to use a rheostat to control the fan speed, your motor must be of the split capacitor type."
Dayton 4C831 is of the split capacitor type. What am I missing?
