Anyone know the cfm rating of the newer style (96) electric fan?

TIA, Dan

Good question - no idea what-so-ever.......and nothing in the FSM.

But, if you really need to know - you could measure the diameter
of the fan, multiply it by the depth of the blade, divide by 2, scale
it to feet, and then multiply that by the rpm - that would give you
cfm.

My pull-it-out-of-my-butt guess, would be 1000 cfm.

Good luck !

sounds like more math than I want to deal with, but feel free to warm up that calculator.

Thanks, Dan

The Twin Line dual electric fan assembly (2 - 10" dia fans)
is rated at 1800 CFM, assuming 2500 rpm @ 13.5V, 15A. That's
at zero static pressure - at 60mph I'd guess you're doing better
then that.

On the safe side - 1000 CFM may have been a little optomistic
maybe more like 800-900 for each fan, standing still.
