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

Yes, if you:

  • Carry gear on top of your camper and want to make sure you can still open the vent without hitting the roof rack
  • Have a van, pop-up camper, or small trailer and need a fan to circulate air without taking up much roof space
  • Prefer to buy American

No, if you:

  • Could use a handy night light in an area that's otherwise kind of dark - there are similar options with built-in LEDs
  • Stay in really hot places where you need a stronger fan to keep you cool
This roof vent uses a 12-volt fan to circulate air in motor homes and enclosed trailers, keeping interiors ventilated without compromising security.

We use one of these in every trailer we make. They are reliable, easy to install, and attractive. We do install them on the side of the trailer, as we don't like to make holes in our roof.


Our hunt club has 2 pit blinds that are used for waterfowl hunting. Each blind is essentially a concrete box with walls, floor and top 4 inches thick and dimensions of 12'x5'x5'. Each blind is buried to a depth of 5 foot to where the top is flush with ground level. Access is through the top using 24 inch wide manhole lids that are made of high density plastic. The cooler air inside of the blinds clashing with warmer air absorbed by the concrete and manhole lids at ground level caused condensation that made the inside damp and smelly. We only hunt 3 months each year, so needed a vent solution for the other 9 months the blinds were not in use. We also needed something that could be powered by DC voltage from a solar panel due to the remote location. In July 2015 we installed each fan into a manhole cover and used water-tight conduit and electrical boxes to run the wiring from the solar panel to each fan. Great solution! Once enough daylight hits the solar panel the fan blades start moving and run constantly until sundown. Will see how long these things last but so far so good

It has been a trial and error experience this past year, but now believe we have things figured out. We outsmarted ourselves and upped the wattage of the solar panel array this spring to run a pump and the fans, but didnt properly calculate the impact that would have on the fans. Bottom line, we sent too much juice to the fans and fried the motors. Luckily, etrailer sold replacement motors. Replacement was a breeze, and lesson learned. After that we split the solar panel array and now the correct voltage and amps are being used and no issues whatsoever. We also had a battle with mice getting inside the fan housing when not operating and making nests, which was a real mess. Solved that by opening the adjustable fan housing just enough to circulate air but not enough for Mickey and his friends to make a condo in the fan housing. Knock wood, the lessons learned this past year should make for trouble free operation from now on. I know that we are not using these vent fans in vehicles, campers or trailers as the majority of you do or intend to do. If we can make these fans do the job in our application, using these fans as intended in a vehicle, camper or trailer using a 12 volt battery and not solar panels and staying clear of rodents should be a breeze.

Hello all.
I have a 1973 Apache Pop
up, the original vent was missing so I looked online for a replacement and I came across this ventline vanaire roof vent, the vent fit perfectly in the original location of the old vent . This pop up has hard sides when you bring the roof down the side walls meet in the center but leave a gap between each other the handle for the vent fits perfectly in the gap. This memorial weekend we vacationed at Lake Isabella and it gets windy when the vent was closed it stayed closed no matter how strong the wind was. It was a success and worked perfectly. Thanks and I am a happy camper.

A year later and Everything works perfect still looks new. Never had a problem , no leaks no noises all around a perfect product thanks. I forget its on cause its so quiet ??.

The unit was easy to install, but it is not powerful enough for the trailer I have. I have a 5 x 8 enclosed trailer that I use for my landscaping business. I needed an exhaust fan to help remove the hear from it while closed. Havi g a phone conversation with one of your employees, I made the purchase. Just not what I expected from etrailer

Its a shame that this is not fitting your application. I have sent your information over to our customer service department for them to assist you in getting the correct unit.

Thoughtful, cheerful service. The fan was exactly what I needed for my motor home. I'll definitely be back for more purchases.

A bit noisier than Id like, but excellent venting is worth the inconvenience. The biggest problem is lets of water on the toilet lid during rains, evev if stopped - lid down. It appears to be coming in through the lid seal, which is cheap foam. Not a large amount, but Ive never experienced driving during hard rain. Well see ... !

I bought this 6" fan a year ago and it is still going strong.
I mounted it vertically on the rear wall of my van conversion boxvan(RV Off-Grid Campervan) about 7" from the ceiling. It was a good fit because I didn't want to cut a hole in my roof and my ceiling. It pulls all of the hot air out of the room within less than a minute. If you want to mount yours vertically as well it will operate just fine with no flaws. Water has never leaked through the unit at all even while mounted on the wall instead of the roof. I recently recommended this fan to someone who needed a fresh air fan for summer as well in a van. Perfectly satisfied with this fan, recommend it and would buy again if the need arises!
Thank You


It was pretty easy to install and looks great on our cargo trailer.

It works very well and is nice and quiet.
Rick K - 10/17/2022


It works. It doesnt leak. My complaint would be its rattling noise; indicating a low quality fan motor. Possibily out of balance.


This little fan is working absolutely perfect in my homebuilt teardrop trailer. It's small size and low profile make it perfect for this project. It would even open if I installed a roof rack which is the main reason I avoided the larger 12x12 roof vent fans not to mention it was a fraction of the cost. It looks great and works excellent. Hot evenings are not an issue with this fan providing great ventilation, drawing heat out the roof and pulling in cool air through the doors. I highly recommend this fan. It was extremely easy to install and seals up tight with no leaks or issues of any kind.


We purchased this product to go in our truck cap as part of a camper build-out in the bed of our truck. This roof vent fit the requirements for size. One of the the limitations was we needed to address our roof rack, and the need to have the vent open with the kayak on the roof. The other concern was with the thickness of the cap, or the lack of consistency in thickness. So trimming of the vent trim ring was necessary.
When we first turned the vent on it didn't seem like it was drawing any air, so we did a smoke test with the vent and it was working just fine! This was done as a quick test. Now we have the vent connected to the aux battery fuse block and run it while we are working on the rest of the interior build-out. It makes a noticeable difference when it's on.
It is a little bit noisy, so we'll see if it keeps me awake at night.


A direct replacement for the original bathroom vent in my 20 yr old Airstream. Very easy installation. Nice product. The improvements incorporated into the new one make it much quieter and it moves more air than the original.


Just installed the Ventline 6 1/4 fan in my horse trailer. Simple easy and works great.


My order arrived on time and in good condition. Installation was relatively easy. Once installed they work quite well. It will make traveling on the road with my dog much easier because of the amount of air that is moved. I will send pictures next week of the installation.

One comment, the instructions call for a 6-1/4" hole. Someone needs to tell the manufacturer that hole saws only come in 6" necessitating additional cutting for an accurate fit.

Thank you

Still doing the job!

I am in the midst of bringing a 1979 Avion trailer back to its former glory. Lots of updating and repairs underway. The trailer came with a hole in the bathroom ceiling instead of the vent fan that once lived there. I searched around and found this vent fan, and at the best price here at etrailer. Perfect fit! Installation was a piece of cake. I am very happy with this product and etrailer and will continue shopping here as the renovation continues.


Great weatherproof ventilation solution. Good air flow and simple install.


It’s a nice little dc push-up/pop up type 12vdc fan. Draws about 1.2 amps pushing air. The inner side cover allows for a 2” thickness of roof/wall but my use was thru 1/2” plywood so I had to trim the inner cover to get it close to flush with the ceiling. Used clear silicone all around the underside of the mounting surface and 1/2” screws to seat and seal it in place. Part of my home made wood truck bed cap I’m setting up for camping. I expect it should work nicely. Will have to see if it stands up to stints of 80mph on the freeway. Might be nice if there was an option for a metal cover instead of the plastic one.


I was in need of a bathroom fan to replace the original in my 2019 Airstream Classic and found a possible match on's website. I emailed their customer service to verify it was the right part, and within an hour, Bryce D quickly and professionally answered all my questions. I received the fan within days of the order and it is identical to the original. Thanks Bryce and for the prompt service!!


I bought a Chevy City Express van, which is the same as a Nissan NV, with the intention of turning it into a little one person camper. Needed a roof vent, a standard square vent wouldn't fit between the roof ribs. Found this one. A friend installed it for me, he just wired a 12v plug on it, and I plug it into my portable jumper box. It will last 2 nights before it needs to be recharged. Works good.

So far, so good.

I purchased this vent to remove damp air causing mildew growth from a plastic utility storage building on a concrete slab. The vent itself installed in under 5 minutes using the inside flange collar as a template and a reciprocating saw to cut the hole. I used gutter sealant and self tapping screws to attach to roof. I hooked the device up to a small solar panel and away it went. The 560 cubic foot storage building was full of dry fresh air in under 24 hrs with no sweating or condensing moisture as it was the prior day.
Very nice push-pull design to open and close the vent. Has a push button switch for power but I intend the let it run full time when the sun is out.
Thanks e-trailer, Best prices on the Internet too!

Been running 365 days later with flawless operation

Purchased the Vanair Ventline fan to replace the one that was original equipment on our 2003 Teton fifth wheel. The old one was very noisy and I had already repaired the cover once. Shipping was cheap and fairly quick (UPS ground). The price was good. Installation was easy and the new unit fit perfectly.
I now have a very quiet new fan in the bathroom.

This fan has worked flawlessly for the past year. The only thing I recommend is to vacuum the fan screen about once every two weeks.
William - 02/02/2015


My son finally got the roof vent hooked up he ordered from you, he hooked it up with a solar panel in the back of his 86' suburban to get more air back there.


This is a great exhaust fan. I use it in a two fan system. One max air that can push and pull air, and this one, to get good air flow. Easy to install and does the trick. I would recommend.


To order was easy,very fast delivery, installation on teardrop camper went as I thought it would,works to vent camper, works very good. Quiet and looks good , I like it. GB.


Great product! Came prebuilt, with simple easy to read instruction. Installion in the roof of my van was very simple. Couldn’t be happier!


Got this as a replacement for one that was installed in my 1982. Bluebird Wanderlodge. The old one finally died. The new one has a considerably smaller and less robust motor but it seems to work OK. It's just enough different that most parts are not interchangeable. It's really meant for small campers and vans. If I did not already have the hole in the roof I would have gone with a larger vent with a big fan.

Ok,no leaks
