Thermostat-controlled roof vent with 26 settings has a rain sensor so that the dome automatically closes and the built-in reversible, 12V fan shuts off if rain or snow hits. The powered lift eliminates hand cranking, and a remote control is included.
Features:
Specs:
This 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 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.
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 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.
To reverse the direction of airflow, simply push the air out/air in button while the dome is open.
This 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. An up/down button on the remote also lets you 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 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.
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 was a great addition to our trailer. This is a remote control model because the ceiling is too high to reach from floor level. With two high volume fans we can circulate a trailer full of air quickly. I wouldn’t be without a fan like this.
Installation was easy and a perfect fit for my 2021 Airstream 16RB (replacing a 3 speed Fan-Tastic unit). I like the speed range of this fan, and how quiet it is when set to 50% and lower, big improvement.
However, all the other features (rain sensor, temperature setting, reversible direction), not so impressed with. I don't like the fact the fan turns on at full speed every time I switch on the battery disconnect (applying 12v power). Why is this necessary? I also have a hard time determining which direction fan is pushing air (pulling air into the trailer does not produce strong air flow), and maybe the vent cover is preventing good air flow. It would be nice if there was an LED on the remote or unit to indicate direction (forward or reverse). I know that sounds silly, but I put my hand up to the unit and can't feel which direction the air is flowing, it's just moving around.
I ignored recommendations to go with a Max Air unit, and if I had it to do over, I would install a Max Air instead with built-in cover. I may even do that anyway just to have a better fan and cleaner look.

Ive finally had it with this fan. It wont stay open, closing on its own and I cant stop it from doing that with the remote. The rain sensor has been turned off since it was installed, and yet it keeps trying to close when its closed. A waste of money. I just ordered a MaxxAir 4500k for my Airstream, and life inside the trailer should be nicer from here on out.
Works great! Replaced the original unit from our 2008 Motorhome.
I am a retired rv collision center owner with many years of rv extensive repair experience and, I always wanted to construct a slide in no cab over camper. My first concern was to be able to remove my camper on my own and be able to roll it off and on and have the ability to move it around in my RV barn to clean under it and be able to put it against any of my walls for storage. I discovered your name on the internet and compared your prices on name brand products to complete my build. I could have bought a fan for half of the cost of the fantastic fan but, there is no comparison to the quality of the fantastic fan I bought from you guys and got it almost instantly. I have also purchased a ceramic low profile rv stool that is a step above all the others that I looked at a great price as well.I’ve forward you the pics of where my project has recently stopped temporary because I just had cataract surgery. I can lift my camper off my truck and, spin it like a top and, roll it any direction and, now I’m prepared to go full steam ahead and, I need many more extensive list of components Electrical,plumbing,water,lighting,solar system and a wide array of misc. I’m building this camper for my own personal use but, I already have a person who is interested in buying it when I’m done so if your pricing stays as competitive as it has so far I see no need in opening a wholesale rv supply account. I’m hoping that you might have a solar panel person that I can touch base with give me information on the right and quality solar set up. Thank you Ted
Super fast delivery from etrailer! Fits great, works great and I'm sure it is going to be a wonderful improvement to the RV. Easy install, not counting dicor removal??. Two wires only.
Installed fan. All functions work. Except the fan blade is defective. Fan blade assembly rim has an axial runout of 1/4 inch, inner hub of fan blade assembly has a runout of 3/16 inches. Fan blade wobbles excessively. Obviously a mfg. defective part. The worst part is how difficult it is to get customer support from eTrailer or Domestic to just get a replacement fan blade. Should be simple. It’s not.
Probably easer to just order a replacement fan blade and avoid the trouble of a warranty claim.
Delivery was Great. Fantastic Fan is a great product. My installation was easy and straight forward. The fan fit perfectly into my existing roof vent cut out. Really like the bi-directional air flow feature.
I would order this item from etrailer again if I ever needed to.

Still working the same as new. We run the fan on low all night every night to help prevent condensation in our tralier. This is working well for us
Easy installation, abundant features, really helps remove the hot stagnate air from our travel trailer. Well worth the price.
The plastic lid broke at the screws of the rail brand new survived 2 trips already ordered the new one
Service from etrailer was fantastic. The fan arrived quickly, was in new condition, and works great!
The lid motor broke after a couple months so I contacted the manufacturer (Dometic) and they said it had to be repaired at an rv dealer. No dealer would look at it and one told me it was a disposable product and even if they ordered parts it was unlikely that Dometic would send it to them. He said I would have better luck returning it to be fixed or replaced. I called Dometic and ask them for an address to send it to and they argued with me and said there was no address, so I kept asking for a supervisor and finally they let me talk to a person who said they would just send me a new lid motor. After months of arguing with them they did what I asked them to do in the first place. I purchased a Maxxair fan from Etrailer and it works great. Fantastic fan used to make a quality product but not anymore. It’s sitting in my shop until I can figure out what to do with it. It was a waist of money. I will replace my other 2 vents with Maxxair fans. Also I had it open and a light wind came up and the lid broke. They did send me a new lid but I was afraid to leave it open if not around. Also my rv came with another Dometic fan and the crank handle is stripped. Pure junk! I would not buy a Dometic fantastic fan and try not to purchase anything from Dometic. It is my opinion that they will not improve their products as long as RV manufacturers keep purchasing them.
The fantastic fan is just that, FANTASTIC! I would not consider any other fan for the purposes that I use it. There are so many different modes of operation that it will cover any need that you may have. The rain detection is very important in my area.

The product is working great. I will not consider any other product.
We bought two of these a little over a year ago but have only been using them consistently for about 6 months or so. We are full-timers and have been through Florida in March, up the East Coast, and across to Ohio so far with these and couldn’t be happier. They are literally on all day and all night unless we’re in transit or it’s raining so they have gotten quite a workout already and they’re still working like new and are remarkably quiet (you can likely hear the traffic, breeze, and fiancé walking in the background of the video and the fan is on medium). Our only complaint is that the rain sensor can be a bit sensitive and likes to close with a heavy dew and tends to be reluctant to open back up immediately after a rain, but we’d MUCH rather it be overly sensitive than not sensitive enough and us get water in the camper! We also travel with two animals so having these fans has given us the confidence to leave them alone during warmer days without the fear of them overheating (we also have our camper well insulated, the awning providing shade, and a Wi-Fi thermometer constantly monitoring the temp so don’t worry, they are safe!). And even with both fans running almost constantly they don’t seem to draw much power which is essential for boondockers. Overall these fans are definitely on our top ten favorite purchases for our Airstream and we would buy them again without hesitation. HIGHLY recommend!!!
Delivered ahead of schedule. Looks good and it will be installed shortly. Expecting good results. Have dealt with this product and E trailer previously.
I have this fan for a year now and etrailer sent me a link to rate it which I think was really cool. I'm very pleased with the fan. It was super easy to install. I love using it to clear my rv of smoke when I'm cooking . Also I don't use the ac on cooler days because this fan really pulls the air in from the windows. This item was a perfect upgrade and I'm still happy after 1 year with it.. thanks etrailer.com for the fast shipping and great price
After 1 year of service our fantastic fan is all we hoped for. Installation was easy as we had an existing oem fan we replaced. The remote function is a must as my wife is short and wouldn't be able to reach the ceiling to operate the fan. it moves much more air than the original and is actually quieter. Cant speak for the rain sensor as we have the roof vent installed. Highly recommend!!!
This fan functions excellently. However, the plastic cover was damaged by the closing motor due to the amount of closing force. This occurred a few weeks after install as it had been being damaged with each open/close. I did not request a new cover realizing the same thing would happen so I modified the mounts for the closing mechanism and all is well. This all required removing the vent cover to correct.
We replaced a regular vent fan in our trailer with the Fan-Tastic vent roof fan. We had Fan-Tastic fans in our two previous RV's and they work wonderful. As we downsized our RV this time, we only have one A/C unit. The bedroom needed a bit more cooling. Love the rain sensor and remote features.
We put the fan in on the backside on our concession trailer. A freezer is in front of the fan; so, we use the remote to open/close and adjust the fan. The fan acts as a vent for the hot air from the freezer and a commercial refrigerator. It works great like that.
I purchased one Fan-Tastic vent and one AirMaxx vent. They both have remote controls and operate the same. They are very similar in design, weight and noice level. AirMaxx has a much better remote control to change settings. AirMaxx was $XXX cheaper at the time of purchase in 2022.
Installation was a breeze. Hardest part was getting old vent out. Wife can now open and close the vent. First drop of water and the vent closes.

Fan is doing a great job, it clears the smoke out when I burn the toast. Dont have to use the air conditioner as much.
I love the fan. I had a manual one in the trailer I purchased and I couldn't reach it without a stool. I am 75 and that wasn't going to work
Had a customer with a manual push bathroom fan on a park model. There was no way you could turn it on without dragging a step stool in to reach it? Poor design originally but this remote control fan is the ticket for situations like I am describing. Simple installation, customer loved it!
Have not installed it yet. I am excited to get it put in, I can't reach the one currently there and with the new one and remote I will no longer have to stand on a stool.
It was a good price. I will send pictures when installed.

The unit was easy to install and it works better than I expected. Using the renote with all the features makes it easy to use. It is quiet, and at night it pulls in the night cool eliminating the need to use on many nights, especially if the hook ups is 20amp. dont have to use the stool.
Love this fan. The thermostat control works great especially at night. I put it in the bedroom and having the ability to have it blow down on the bed is a game changer boondocking on a hot summer night. High quality, easy-to-use remote definitely worth the extra money for the additional features.

After a year we still love it. We have 2 fans in our camper and running them both when we get to a spot to cool the camper down works great. It is a great option in the bedroom instead of a second air unit.
Do you have a question about this RV Vents and Fan?

Working as expected. We Camp in areas with no access to grid power. Being able to cool the interior down overnight is important to our comfort. As mentioned, we would not be camping without this fan. Excellent purchase.
