On my '92, I have a Kool-O-Matic exhaust fan in the closet in the bathroom with a metal all-weather hood. I believe those are 1/10 hp, 8 amp motors driving a 12" 4 or 5 blade deep pitch fan (I forget which). I have not been able to find a cfm spec so far but they move a LOT a air. They seem to more much more than the fantastic type fans I had in previous RV's. Mine is in the closet over the washer/dryer combo and it pulls air hard through the round air intake ducts around the top of the closet unless you leave the door open. Unfortunately, Kool-O-Matic is no more and replacement parts are very hard to find. Back in 2008, replaced the motor, the thermostat and the 3 speed switch with new parts from the remaining inventory Kool-O-Matic had. Fortunately, it is still working great.
