Is this right For you? Product Expert Kathleen M says:

Yes, if you:

  • Spend a lot of time in your RV and need to be able to pull cool air in or push stale air out with the reversible fan
  • Like being able to flip a switch to open the vent instead of standing there twisting a knob
  • Camp in areas with frequent rain showers and want the vent to automatically close

No, if you:

  • Have a hard time reaching up to access the controls and would rather have a wall switch or remote
  • Want to use the fan while the lid is shut, like a ceiling fan, to keep air moving inside your camper
  • Like to leave the vent open while driving to get fresh air
The rain sensor on this thermostat-controlled roof vent ensures that the dome closes and the variable-speed, reversible, 12V fan shuts off when rain or snow hits. Powered lift eliminates hand cranking. Lowest Prices for the best rv vents and fans from Fantastic Vent.

This Fan-Tastic Vent roof vent has a built-in 12V fan that uses a thermostat to help maintain an even temperature inside your RV, camper, or enclosed trailer. You can also control the dome and fan manually with a built-in hand knob or with controls on the vent housing. 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 Thermostat

Air out your RV after cooking or just draw in some fresh air while you sleep. This variable-speed ceiling fan operates in 2 modes: manual and automatic. The fan activates when you move the fan blade rocker switch to the in or the out position, which designates the direction of airflow.


When using the automatic mode, you can preset the fan to maintain a desired temperature inside your RV. The thermostat dial is color coded, with dark blue representing the coolest setting and dark red representing the warmest setting. 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.


To control the fan manually, turn the speed knob on the vent housing. There are 3 speeds: low, medium, and high. There is also an off position.


Power Lift and Rain Sensor

Fan Tastic Vent Lift Dome

This Fan-Tastic Vent has a powered lift arm for the dome, so you don't have to manually crank it open or closed. The dome automatically opens when you turn on the fan. You can also use the small rocker switch on the vent housing to open and close the dome when the fan is not running. 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 it 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.


Installation

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.

Customer Reviews

Fan-Tastic Vent Roof Vent w/ 12V Fan and Thermostat - Powered Lift - 14-1/4" x 14-1/4" - FV803350

Average Customer Rating:  4.7 out of 5 stars   (29 Customer Reviews)

The rain sensor on this thermostat-controlled roof vent ensures that the dome closes and the variable-speed, reversible, 12V fan shuts off when rain or snow hits. Powered lift eliminates hand cranking.

by:

The vent only opens and closes if the fan is actively running. Kind of annoying. I just want to open and close regardless of fan running or not but that is not an option. So for instance...say I just want to open the vent but I do not need the fan..nope. You need to turn the fan knob to on...then toggle the open/close switch.

And further... First trip with it the plastic vent cover broke right where the metal lift arm attaches. This is the worst. I can deal with the vent/fan working in an odd combination but the fact that it broke already is very poor.

Hope I can get in contact with someone at etrailer about this.


Comments
I will have our Customer Service team reach out to you. I reached out to the manufacturer about opening the lid without running the fan. They advised that you can use the knob that is attached to the lift motor to open the vent while the fan is off.
-- Etrailer Expert Jenny N - 05/06/2022

Absolute waste. It seems like when the company was sold they changed the programming and instead of fixing it or giving customers an option (read: a simple switch!) they made it so the rain sensor just shuts it permanently absolutely destroying any usefulness of the rain sensor. Customer service doesn't even understand the problem (e.g. getting up at 3 am because of a 2 minute rain at midnight to cycle the fan power) or alternative uses (e.g. using the fan to prevent overheating for longer periods- an all day hike). It now just closes permanently a the first drop of rain instead of reopening when the sensor is dry.

I literally ripped this brand new fan out two weeks after install and a year later it's still sitting on my workbench because I refuse to hobble someone else with this absolute piece of garbage before I get a chance to override the problem with an FRM01 12v relay computer. I haven't bothered because 1. I have a better fan (the old version I was lucky enough to find) 2. this one has a chimney which sits up 2" higher 3. the new motor is weak enough that even if nothing else was wrong it would still be a mediocre fan.

The old model has a horizontal front hinge and a black motor housing that extends into the lid. Beware a lot of images of the old model are still used in listings for the new model.



by:

Excellent product and easy to install. The Product did arrive with some slight damage but etrailer send me a new part right away. Highly recommend dealing with etrailer.



by:

Love the fan. Replaced an origonal vent on 1976 GMC Motorhome. Required a little cutting as the old vent had rounded corners.



by:

I love the fans. I bought two and they help keep my rv's temperature at a reasonable temp. I would rather have fresh air than use the air conditioner.



by:

The quality looks very good ! I just received the package and have not installed the fan yet.
I do like buttons on the fan instead of on a remote control. More direct.
The price was great and the service was fantastic !!.
I know this fan will fit perfectly as upgrade for replacement on my old fan.



by:

Wanted to upgrade the feeble factory bath vent so I went with this one. As always etrailer was the best price and delivery was perfect.

The ordering process was great.

etrailer is my "go to" place for rv accessories, everything I've received from them has been delivered on time, and the products are quality. They pack the merchandise very well, nothing to date has arrived damaged. I am very satisfied with the products and service I receive from them.

Haven't installed it yet,so far so good. Thank you so much..

The vent roof fan works very well

Installed on my 2003 5th wheel. The best part is the rain sensor to close it!! Shudda bought this years ago. Great product and as always, here on eTrailer, MY "Go To" store. I always seem to shop this site, simply the best for products and SERVICE.



by:

I received my fan and installed it the same day. They kept me informed when it was shipping and even called to verify my shipping address since it was different from my billing address.
Good people to work with and pricing was very competitive



by:

I have not installed the product yet, but it is exactly what I ordered. It is a replacement, so I'm sure it will be just fine when I put it in. All the pieces are the same as what I took out. Delivered quick and in good condition.

Ask the Experts about this Fantastic Vent RV Vents and Fans



  • Troubleshooting Fan-Tastic Roof Vent FV803350 That Doesn't Open Or Close
    First thing you will want to check is that the fan has power and is grounding properly. You can try using jumper wires to the vent wiring that are run to known ground and power to see if that works. Next, you can check the fuse of the fan to make sure it is not blown. Near the speed setting is a plug that holds a 4 amp fuse. I attached a picture that points out where it is. If the fan still works when you manually open the lid that would indicate a problem with the lid motor. Since this...

  • Will Fan-Tastic Vent Roof Vent Work With Solar-Powered System
    Since you said your solar powered system is 12V, it would work great with the Fan-Tastic Vent Roof Vent, part # FV803350, as long as it provides at least 4 amps. This vent has a powered lift and a built-in rain sensor, and has 3 speed settings to let you control the air flow. This fan is designed for roofs up to 4 inches thick and the rough opening needed for installation is 14-1/4 x 14-1/4 inches.

  • 3-Speed Non-Thermostat Fan-Tastic Roof Vent Recommendation that is 14 inch by 14 inch
    Sounds like you are looking for the part # FV801200. This is a very similar roof vent to the part # FV803350 you referenced at a lower price point that does not have the thermostatic features. I attached a review video for this vent for you to check out as well.

    Yes, the Fan-Tastic Vent Roof Vent # FV803350 has a rain sensor that will close when it rains or snows but then re-open once it dries. The fan will also automatically re-start once the dome has opened.

  • How to Correct Squeak in Dometic Rain-Sensing RV Vent with Fan
    If your Airstream's Dometic powered vent has a visible accumulation of soils from regular use keeping the trailer free of cooking odors then you can certainly clean the fan blade and other accessible surfaces. It sounds like the squeak is coming from the fan motor itself, though, so for that I suggest a very light application of WD40 or a similar lubricant. If the squeak reliably stops after a moment or two then to be perfectly honest I would do nothing to the fan/vent other than clean...

  • Fan-Tastic Vent Fan FV803350 Compatibility with Existing RV Wall Switch
    You should be just fine replacing your two roof vents with the Fan-Tastic Vent Roof Vent # FV803350 since these fit the standard 14-1/4 x 14-1/4-inch RV roof opening size. Since you are replacing two 12V powered vents with two similar units your existing switch should work but the air direction and thermostat functions will be operable on the new fan units themselves.

  • Fan-Tastic Vent Roof Vent with Fan and Thermostat Amperage Draw
    I reached out to the manufacturer and the techs don't have that amperage for each speed of the Fan-Tastic Vent Roof Vent w/ 12V Fan and Thermostat # FV803350. They said that at start-up the fan will pull 3.5 amps but running will remain well under that amperage. The unit has a slow blow 4 amp fuse so it will not pull minimal amperage at 12V for continued operation.

  • Replacing or Repairing Rocker Arm on Fantastic RV Roof Vent
    When repairing or replacing the rocker arm like # FVK8011-05 on your Fan-Tastic Roof Vent, you shouldn't need to remove the entire fan assembly. Working from inside the trailer/RV and looking up into the unit, you should be able to first remove the screen. With the screen removed, you will want to remove the knob which is likely held in place with a screw. You may then need to remove a plastic tray which will give you access to the rocker knob. You can then see if anything has broke or...

Basically this is designed to fit the Fan-Tastic Roof Vents to turn it into a 3350 series of Fan-Tastic Vents like part # FV803350 to give it the ability to have automatic lift with 3-Speeds, reverse directions, a thermostat, and a rain sensor.

    There are only two wires on the Fan-Tastic Vent Roof Vent w/ 12V Fan part # FV801208, a white wire which is the ground and then a black wire which is the power. The ground wire will need to be ran to a bare metal surface and the power wire will need to be ran directly to the battery, it does not go to a thermostat as the controls for the unit are on the bottom.

    The model Fan-Tastic fan you have with the wall mount is discontinued so the only option is to replace the fan and remove the wall mounted thermostats. You can replace the vents with the Fan-Tastic Vent Roof Vent w/ 12V Fan and Remote # FV807350 which comes with a remote to control the fans instead of the wall mounted control.

  • Availability of Fan-Tastic Roof Vent with Rain Sensor to Close Lid
    We have a very similar Fan-Tastic roof vent to the # FV801250 that does have a rain sensor, but this one does not. Since this is a manual lift lid there'd be no way to automatically close the lid if rain was sensed. So instead you'd want the part # FV803350. This has a powered lid lift that when the sensor gets wet will automatically close the lid.

  • Fan-Tastic Vent Rain Sensor Light Stays On All the Time
    The rain sensor doesn't have to be activated. When it gets wet it will automatically close the vent lid. When it dries it opens back up. But it sounds like yours has a short that is causing that light to stay on all the time. In order to get the replacement rain sensor you would need upgrade kit # FV803358 which includes the sensor.

  • Solution for Fan-Tastic Roof Vent that Runs Constantly When Fuse is Installed
    Sounds like there's an internal issue with the Fan-Tastic roof vent you have. Most likely a circuit board issue. With the Fan-Tastic roof vents there isn't a replacement circuit board available but you can replace the "guts" of the vent with the # FV803358 which does take care of the circuit boards and lift/fan motors. This would be best solution to get your roof vent working again. I attached a review video for more info on this as well.

    The specific screw you're needing to hold the fan blade to the motor shaft on your older model Create-A-Breeze Fan is no longer available. You might be able to find some replacement hardware from an online re-seller, but the screw itself isn't produced anymore. Your best option at this point is really to replace the fan assembly itself.

    Your Fan-Tastic roof vent is old enough that we don't have the individual part you are looking for so the best option we have would be the Fan-Tastic Vent Roof Vent Assembly Upgrade # FV807357 which would replace what you have with the current Fan-Tastic powered lift setup with a fan.

  • Does the Fan-Tastic Vent Upgrade # FV807357 Come with a Fan Blade?
    Since the Fan-Tastic Vent Roof Vent Upgrade # FV807357 is designed to work with Fan-Tastic vents with fans that are already installed, it does not come with the fan assembly with the kit. You would use the same fan from your Fan-Tastic Fan model 2000BTS-B and use it with the # FV807357 With that being said, if you need a full setup that includes the same rain sensor functionality with a powered lift, that is the Fan-Tastic Vent Roof Vent w/ 12V Fan and Thermostat - Powered Lift - 14-1/4"...

The powered fan is reversible so it can be used to bring in fresh air or to exhaust hot air out. The fan features a thermostatically controlled 3 speed motor.
