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. The fan can also be controlled manually with the built-in hand knob or with the controls on the vent housing.

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. To activate the fan you can either turn the speed knob to the desired setting or you can simply activate the in/out switch, which will cause air to be pulled into your trailer or pushed out of it.

To use the fan, you must first manually open the dome by turning the hand knob. The dome must be left open while the fan is set in automatic mode.

When using the automatic mode, you can preset the fan to maintain a desired temperature inside your RV. The thermostat dial shows a range of temperature settings that are color-coded from dark blue to dark red. 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.


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.

The 2250 Fantastic Fan still working great after a year! Pretty quiet and the thermostat is a handy feature that works well. In my application, it has a tendency to open itself while driving around unless it has been cranked down fairly hard. Driving with it open doesn't seem to be a problem other than the outside noise that comes in that way. My application was a fiberglass raised top on a Chevy van. I had to make a wood frame as the fiberglass did not provide a flat surface to mount to. Photos below show inside frame, fan, and insulation.

my Fantastic Fan is working GREAT! We installed it in a 15 pass van converted to a camper with 24 raised top. The van is very well insulated all around with interior curtains as well. The thermostat works great still. I describe it as equivalent to being in a shaded gazebo. We are quite comfortable leaving our dog in the van for any length of time parked in full sun as long as she has appropriate water and food supply. She always seem quite fine and happy on our return. Quiet enough to leave on during hot night. Thermostat will turn it off when it cools suffeciently. Very happy with unit.

The Fan-tastic vent roof fan arrived much sooner than expected. When I opened the box to inspect the fan every thing looked very nice. It will probably 8 weeks/ early May when the weather is nicer before I install the fan. It will be a nice improvement for the trailer.

- FV802250

So far this fan has been an upgrade over the previous competing brand it replaced. It is quieter, if a bit less powerful. It's not my first Fan-Tastic RV van and it won't be the last.

- FV802250

Only recommendation is to keep the sensor's push pin clean,that activates fan when opening vent. Dirt/sand will build up and prevent fan motor operating. Darn blowing sand in the deserts!

- FV802250

On the cover, the screws connecting it to the linkage to raise & lower the cover broke off the plastic they were connected to. On our 1st trip & after maybe 3 or 4 uses this happened. I"ll be ordering a replacement cover soon. I don't know--maybe wind is responsible. Otherwise, an excellent product. And was easy to install after removing the original, cheap one.

Customer Service will contact you. The dome has a lifetime warranty.

I love my new fan! It is great for keeping fresh air circulation in my truck camper. I live in my camper full time so it is getting used regularly and I just can’t say enough good things about it. Installation was a snap. I actually did it up in the mountains. The night before, it rained hard all night and I experienced several leaks that night. Next morning I installed the new fan and of course stopped the leaks. I highly recommend it.

- FV802250

Great service!! I had to add something to my online order and had to call eTrailer. Terri N was VERY helpful. My revised order was received 5 day’s earlier than expected.

- FV802250

Very pleased with the fantastic fan/vent. Easy to install. Delivered on time

Last project built. Used etrailer for almost all parts, including roof vent and so on. Friend wants one now so started another one. I will be getting all the parts from etrailer...

- FV802250

It's shocking to me how expensive a few pieces of cheap plastic are. It also came DOA. I used my very meager electrical skills to figure out that there was something wrong with the fuse assembly. I couldn't even get into it at first. The cap wouldn't release, and I ended up pulling the whole thing out of its mounting and ripping one of the wire connectors off its connection. I worked harder at it, and the cap came off, leaving the fuse and the metal fuse housing lodged in the tube. I ended up breaking the glass of the fuse trying to get it out. I've never seen such a simple thing work so poorly. I'm a moron when it comes to electrical stuff, but even I have easily and successfully replaced every fuse I have ever blown. After a trip to the auto parts store, the thing is finally working and installed. I played with the fuse to see if it would come out easier the second time, and it will not. If I blow the fuse, I'm going to have to break into it - literally - to replace it. An important note about the thermostat that no one seemed to mention in any of the reviews I read: it is very obviously aimed at a higher temperature range than I would have expected. Room temperature is deep, deep down in the blue zone of the knob. It's about 85% of the way from hot to cold. 85 degrees is about midway. I can't test how low the coldest trigger point is (it's summer when I'm writing this review), but I suspect that it is somewhere around 70. That will be fine for most people, but it not ideal for me. I tend to set the heat around 55-60, and it would have been nice if the vent could have come on at a lower temperature. Closed-up trailers sitting in the desert sun heat up quickly in the morning, especially in the spring and fall. I tend to wake up when the trailer gets too hot in the morning, not really when I'm done sleeping. Otherwise, I would say that my experience mimics those of most other reviewers. It is way better than the complete piece of garbage that came with my cheap travel trailer. It's sort of quiet on the low setting, but nowhere as quiet as it could be if it were made from higher quality components. On high, venting out, it definitely draws in a nice breeze, especially if you only have one window open. It will definitely help when I camp in full sun without tree cover, which is mostly what I do. I wish I could have found a better fan, with a thermostat, priced more reasonably, but I don't think it exists. So, at the end of the day, I am mostly happy with my purchase.

Second one I have purchased. One for my horse trailer and one for my RV. Did not want any other gadgets to contend with, like remotes, so chose the manual lift vent fan.

- FV802250

Easy to install and look great!

- FV802250

Fast shipping. Product arrived as ordered and undamaged.

- FV802250

GREAT! Quick service. Easy installation. Thanks for your help, again.

- FV802250

We bought this a year ago and installed it in our truck camper. We primarily winter camp in high elevation snowy climates and it worked great to dump moisture out of the camper in the winter and it helps circulate air and keep things cool in the summer. Love it!

- FV802250

As always, you have a great price and prompt service. I am replacing the fan in my bathroom. The motorhome already has one of these in the front and in the rear bedroom.... but they installed a CHEAP and noisy fan unit in the bathroom. Upon returning from the mountains, I noticed debris on the toilet. When I looked up, the cover was completely cracked. I thought that maybe I had hit a tree limb or something. I was just going to replace the cover. When I saw the poor quality of the entire fan assembly, I thought that this is the perfect time to replace the entire unit. The other two units have worked great. They draw and circulate air through the whole MH. Great products.

- FV802250

Ordering was effortless and was able to get stuff to carry ebike, hitch plus the bike rack plus stuff for the RV all in one order. The hitch went on effortlessly with your addition of the cables to thread the bolts through the frame. Only took us 10 minutes longer than the video said and we didn't have the Explorer on a rack. The hitch went together fine and it is heavy. My wife can load the 75lb bike without me. Hooray!!! Now I just have to install the light and fan in the RV. Thanks etrailer. Great experience so far.

- FV802250

I was impressed with the large size of fan blades this unit has over the original. Unit was easy to install and works well. Would recommend it to anyone.

- FV802250

Fan has been great and installed easily.

- FV802250

This is a great, simple, fan, though not quite quiet enough for a teardrop build. Even on the lowest setting it is pretty loud and my wife declared it to be too loud for our trailer. We ended up sending this one back and spending more on the remote controlled one with something like 11 speeds. It is much, much quieter on the lowest setting and is currently on our build. I really loved the simplicity of this fan, but noise was a factor in our decision and this one is just a bit too loud.

- FV802250

The fan blades were what I expected....had to drill shaft hole a bit bigger (0.116") and cut plastic mounting shaft shorter by 0.161", but they work perfectly now with old long motor. Tomorrow I tackle installing the new fantastic fan. I am very impressed with etrailer's service!! Thanks, I need as much time to get stuff done as possible!. I

- FV802250

The fan itself works really well....but they have a consistent problem. Had it with my last fan and hear other people complaining about the same issue. When you go down the road the screw that holds the crank handle vibrates loose and the crank handle and screw fall to the floor. I lost the screw on a long trip and had to stop at an rv dealer for a replacement. Sounds trivial but its a dumb little problem they need to fix. Otherwise the rating would be 5*

- FV802250

Not too happy with the product, we installed the fan approx 9 months ago and soon after with only minimal use the black plastic knob that opens the lid stripped and now I have to use a phillips screw driver to open and close the lid until I get a replacement part.

- FV802250

Fan-tastic vent arrived in excellent condition. Our experience with ETRAILER has always resulted in great service, the orders are always shipped expeditiously and we’ve never had any problems. That’s why we’re repeat customers.

Our Fantastic vent is coming up on a year old and still going strong. Installation was a “breeze”. We are very happy with the product.

Just happened to get to take advantage of a free shipping offer and it worked out well. Fast shipping and good pricing. Only thing I would have liked more would have been if they would have recommended putty tape and caulk for the install of the vents. If they had, I probably would have been a buyer of them as well. Anyway, I have heard a lot of good reports on etrailer and with this order, I wasn't let down in any way. Mike

Hey Mike, my name is Cole. I work at on the video team. I just wanted to say thanks for the great advice! We are always looking for ways to improve what we do, and your input helps us with that. Thanks again!
