This Fan-Tastic Vent roof vent has a built-in 12V fan that pushes stale air out of your RV, camper, or enclosed trailer. A hand knob makes it easy to open and close the dome. And you can easily change the fan speed with the speed knob on the vent housing.


Ceiling Vent and Fan with 3 Speeds

Air out your RV after cooking and keep the air smelling fresh. Turn the speed knob on the vent housing to increase or decrease the fan speed. There are 3 speeds: low, medium, and high. This way, you can select the speed that you find most comfortable.



This vent requires a 14-1/4" x 14-1/4" opening in your trailer's roof and ceiling. To replace an old vent, install this vent into the existing opening. If your roof does not already have a vent, you will need to mark and cut an opening between roof joists to install this unit. And the 2-wire design makes it easy to have your vent hooked up and ready for use.
