Fantastic Fan model

Does anyone know off hand which model of the Fantastic Fan comes standard in the T@b? Thanks, Dave

I believe it is the 3350.  I just bought a new T@B and had the factory upgrade the fan to a 7350, because it has a lower amp draw, 13 speeds versus the 3350's 3 speeds and a remote, although the remote was not as important to me as the other features.

Does 13 speeds essentially provide you with a variable speed fan? How slow is the lowest speed?
Sometimes all you want is a gentle flow similar to a home ceiling fan. Or a slow exhaust fan to pull air in from the windows.
You don't need a roaring whirl to do that.
Has anyone tried modifying the stock 3 speed fan to run at half normal speed? Or are RV fans unable to operate at low rpm?

Yes, the 13 speeds gives you, for the most part, a variable speed fan.  Meaning, each setting from 1 to 12 is a slight step up from the previous setting.  On it's lowest setting, the fan turns very slowly.  This highest setting is comparable to the standard fan.  But this model also has a temperature sensor and rain sensor.  The rain sensor closes the vent when it detects moisture.  The temperature sensor opens the vent when it gets too hot inside.  Can't say what happens when it is both hot and rainy; I live in the pacific northwest, so we don't experience those conditions.  I will say that I have this same model fan in my fifth wheel and it has consistently closed at the first hint of rain and opened when the temperature hit my setting.  Both of those setttings are user settable.  Anyway, as I said earlier, my main reason for getting this model was the low amp draw.  The standard fan has amp draws on low/medium/high of 1.9/2.3/3.0 amps, respectively.  The model 3350 only has an amp draw of 0.2 amps on its lowest setting, so if you are battery constrained, you can still get some air moving on very low power.

My understanding is the "stock" fan can be upgraded to the 13 speed unit by replacing the interior faceplate housing the controls for about $150 using the "7350 Upgrade Kit". Has anyone tried this?
EDIT: Also, has anyone tried modifying the stock fan to use a rheostat for a variable speed control?

Subism - Several here have installed the upgrade kit - didn't sound too complicated. A search should come up with those threads I'd think.

I replaced it. Another poster had issues getting it to fit, so, your mileage may vary. It was nice to not only have it using less power, but also run more quietly.

Did it just drop in for you Jenn? Fit fine?

Here is my post on the Little Guy forum that attempted to bring together the collective wisdom of those that have installed the upgraded Fantastic Fan.....

Well, it was a little awkward working with it above my head, but it did fit the space - no mods required.
