This Fan-Tastic Vent roof vent assembly kit uses a thermostat to help maintain an even temperature inside your RV, camper, or enclosed trailer. You can also control the dome (sold separately) and fan (sold separately) manually with a built-in hand knob or with the included remote control. A rain sensor is included as well to signal the dome to close and the fan to shut off when it gets wet.

Ceiling Vent and Fan with Remote-Controlled Thermostat

Fan Tastic Vent Remote Control

Air out your RV after cooking or just draw in some fresh air while you sleep. This remote controls the vent's thermostat as well as its manual and automatic speeds. You can control the direction of airflow - in or out - with the push of a button. Operate the remote control in your RV or place it in the included wall cradle so you will always know exactly where it is.

Manual and Automatic Operating Modes

This variable-speed ceiling fan operates in 2 modes: manual and automatic. An on/off button automatically lifts the dome (sold separately) and activates the fan. To use the manual mode, press the arrow buttons on the left side of the remote or turn the knob on the vent housing to increase or decrease the fan speed.

The manual speeds are listed on the remote from 10 percent to 100 percent. As you cycle through the speeds with the arrow buttons, an LED light next to the selected setting will light up. As you cycle, you may notice that the LEDs for 2 settings will be simultaneously lit. This means that the selected speed is the average of both of those settings.

To switch from the manual to the automatic, thermostat-controlled mode, press one of the temperature arrow buttons on the right side of the remote. When using the automatic mode, you can preset the vent to maintain a desired temperature inside your RV. The temperatures are listed from 60 F to 90 F. As you cycle through the temperatures with the arrow buttons, an LED light next to the selected temperature will light up. Again, when 2 temperature settings are simultaneously lit, the selected temperature is the average.

The fan's internal thermostat will sense the actual room temperature, and the fan will run until the preset temperature is achieved. When the temperature rises above the preset temperature, the fan will automatically kick on again. So when you go out, you don't have to waste energy by leaving the vent running at full blast just to ensure that your RV is cool when you return. And because the fan will activate anytime that the preset temperature is reached, you can set up the system to ensure that your pets remain comfortable while you're out.

Fan Tastic Vent Remote Control

To reverse the direction of airflow, simply push the air out/air in button while the dome (sold separately) is open.

Power Lift and Rain Sensor

Fan Tastic Vent Dome Lift

This Fan-Tastic Vent has a powered lift arm for the dome (sold separately), so you don't have to manually crank it open or closed. The dome automatically opens when you turn on the fan. An up/down button on the remote also lets you open and close the dome when the fan is not running.

Fan Tastic Vent Dome Manual Lift Knob

And a hand knob is built in so that you can operate the dome in the event of a power failure.

A moisture sensor ensures that the dome will close when rain or snow hits. So you can leave the vent running or preset to run at a certain temperature, even if the forecast calls for rain. When the sensor gets wet, it signals the dome to close. With the dome closed, the fan blades will stop running. When the sensor dries, the dome will re-open and the fan blades will resume operation. To keep the sensor from activating in rain, snow, or humid and dewy conditions, simply add a vent cover (sold separately) to block moisture. To disable the rain sensor, hold the up/down button on the remote for 3 seconds.


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.

This kit is to convert a 3 speed fan, to a variable speed. It uses a fraction of the energy of the 3 speed, which is great for boondocking where power is limited. Also comes with power lift, remote, and rain sensor. Install took 30 minutes, including removal of old parts. Be sure to read all instructions before starting, there is a jumper on circuit board that either stays or is removed depending upon which fan motor you have. I also have a vent cover installed which prevents the hatch from completely opening. The automatic opener stops as soon as it hits limits and works fine. Great product and service from etrailer. Also note there seems to be two styles of this kit. One has notched corners, and the other does not. Be sure to verify which style you require. I installed on a NuCamp 2018 [email protected] 400, which had notched corners. 615196

I have been very satisfied with my fan-tactic roof vent upgrade kit vents. They were easy to install & work great. My wife loves them. She no longer has to get a step stool to manually open & close the vents - with the push of a button, they open or close. You can also control the speed of the fan. I would definitely recommend them! And the sales people at etrailer are the best - very helpful & knowledgeable. 892939

Perfect replacement for the house exhaust fan on 2005 Sandpiper 5th wheel trailer. The automatic rain sensor close and shutoff works great as well. 880403

Fast delivery, product was exactly what I needed, and customer service was very helpful 869519

- FV807357

Installed the upgrade in a 2020 [email protected] The installation was fairly straightforward but the instructions are not exceptional, read them a couple times and you will find answers to any questions you may run in to. The upgrade itself is great, using the remote is much easier than knobs on the old fan and the additional settings allow us to run the fan at a very low speed for venting with almost no noise. It is a great upgrade and you should not be afraid of the installation. 824831

Great customer service with follow up and follow through 765730

- FV807357

Fairly straightforward install. Photos in instructions are poor. Unit works great, now my wife can operate the fan. She couldn't reach up to the ceiling where the fan is. 727186

- FV807357

Etrailer provided easy ordering, fast shipping, and immediate and useful help with a small issue. The fan is exactly what we needed to upgrade our existing roof vent to one with more speeds that uses a much smaller portion of our battery storage. 711991

- FV807357

Parts arrived as promised. It was a perfect fit. 706652

- FV807357

Great upgrade for my manual 3 speed fan. Automatic open/close of the cover, better motor range, thermostat for temp control, and especially important to me - much lower power consumption at lower fan speeds. The only issue I had was that the new arm for the cover did not fit the model of fan I have (2019). The good news is that the original one works just fine with the cover motor supplied. 668949

- FV807357

I just completed this upgrade in my trailer. Very happy to replace my noisy 3-speed fan with a quieter adjustable one! 642344

  • Upgrading Older Fan-Tastic Vent That's Is No Longer Working
    It sounds like you are looking the Fan-Tastic Vent Roof Vent Assembly Kit # FV807357, which features the white color you're needing. This kit allows you to upgrade your older unit so that it features an automatic lift, three-speed fan, thermostat, and rain sensor like the current models but it's not designed to fix an existing unit that's not working at all. If the motor is the problem on your 6600 model Fan-Tastic Fan (which is likely) then it would still need to be replaced and depending...

  • Availability of Replacement Roof Vent with Fan and Remote for RV
    The Fan-Tastic Vent Roof Vent Assembly Kit # FV807357 is not a universal fit fan setup so I can't guarantee it will work for you unless you have a Fan-Tastic roof vent currently. The only type of solution I could provide that I can guarantee will work is an all new roof vent with fan and remote like the # FV807350 which would replace the entire assembly you have now.

  • Difference Between Fantastic Fan Upgrade Kits FV807357 and FV807359
    The big difference is the corners of the main panel of the # FV807357 are cut out with small section to allow access to mounting hardware and the # FV807359 instead does not have this area cut out. So you'd want to look at your vents to see if you need the cutouts or not.

  • How Does Fan-Tastic Vent Upgrade kit part # FV807357 Install
    The included hardware of the Fan-Tastic Vent Upgrade kit part # FV807357 that you referenced does screw to the garnish that's already installed which is what clamps to the roof opening. While online install instructions aren't available it's basically just a matter of using the included hardware to lower the inner section of the vent assembly and then replacing it with this after making a few wiring connections. Printed instructions to come with this though.

  • Vent Fan Upgrade for [email protected] 320 CS-S Travel Trailer
    The Fan-Tastic Vent Roof Vent Assembly Upgrade Kit - Clamp-on - Power Lift - 14-1/4"x14-1/4" # FV807357 will not work for your Dometic Fantasic Fan 1450 model without alterations. Because your vent cover lift arm is different, it won't be a direct replacement. If you want all these functions, I recommend removing your current vent and installing the Fan-Tastic Vent Roof Vent w/ 12V Fan and Remote - Powered Lift - 14-1/4" x 14-1/4" # FV807350 as a replacement.

    The Fan-Tastic Vent Roof Vent w/ 12V Fan and Remote part # FV807350 is a complete assembly that will completely replace an existing vent.

The add on while not identical does give you the auto or manual setting and in manual you can choose between 7 fan speeds. The complete assembly has more options than what the stock photo shows on the remote.

  • Fan-Tastic Roof Vent with Motor and Dome for 14 x 14 Trailer Roof Opening

  • Does the FV807357 Fit In The Same Sized Roof Openings as The FV801200
    Yes. Your current Fan-Tastic Vent Roof Vent # FV801200 works with the roof opening size of 14-1/4" x 14-1/4" and a required roof thickness of 4"; since the Fan-Tastic Vent Roof Vent Assembly # FV807357 also works in the same dimension openings and roof thickness it will work as a direct replacement.

  • Will The Remote in Fan-Tastic Vent Roof Vent Assembly Upgrade Kit Operate 2 Vents Simultaneously
    The Fan-Tastic Vent Roof Vent Assembly Upgrade Kit - Clamp-on - Power Lift - 14-1/4"x14-1/4" part # FV807357 does come with a remote but the vents would work off of one remote. You can use the same remote to operate both fans simultaneously and use different settings on each fan as long as the fans are not right next to one another. The remote range is not that long so if one of your vents is in another area of your RV and your changing the settings on the other vent it's not going to change...

  • Availability of Fan-Tastic Fan Upgrade Kit 807357 In Off-White Color
    If your existing fans are of the 3350 series, Fan-Tastic does indeed offer an off-white upgrade kit, part # FV803358 but it is not remote controlled. The # FV807357 you'd looked at is specifc to Fan-Tastic fans, but not to any particular model number and is only available in white.
