Reversible Vent Fan

When a fan exhausts various windows can be opened to provide air flow thruout the RV. When the fan blows in only the area below the fan is affected.

I have two FF's in the 5er. I have, rarely, had mine set to intake - but on occasion have done it.

If I were to do it again, i would opt for having it be reversible.

We had a Fantastic installed in our bedroom and wouldn't be without one. It's the model that's reverseable, with a remote and can be thermostatically controlled. We only use the air out setting 90% of the time to pull through the bedroom window. Never use the thermostat.

Lots cheaper to add your own. What I did. Mine came with the basic FF. I added a reversing switch and a multi speed switch from Dell City Electronics. Think it cost about 10 bucks and my time.

99.9% of the time our FF are on 'out' (exhaust). Creates a great breeze through the rig. Only time we found 'in' to be useful was at home, when we repaired and painted the entry stairwell box.

Ours is on “in” more than out. It’s in a truck camper directly above the bed so when you’re laying up there you get the best breeze. “In” also means the intake air is up high, predictably away from other smells.

Also, if someone uses the bathroom it helps to move the air out the bathroom vent instead of pulling air from it to the main cabin. The same goes for “pressurizing” the cabin to help vent cooking.
