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

Yes, if you:

  • Are replacing an old AC unit and want to reuse the 110V wiring to run a new fan
  • Boondock often and just need something basic to move some air without eating up much power
  • Prefer a solid white lid that lets in light without the sun shining through and heating up your camper

No, if you:

  • Don't trust a single support arm to keep the lid stable in windy conditions
  • Have a 20' long or larger RV and need something with more oomph to pull more air out
  • Have a hard time reaching up to the ceiling to switch on the fan or twist the knob to open the vent
This roof vent uses a 110V fan to circulate air in motor homes and enclosed trailers, keeping interiors ventilated without compromising security. Wedge-shaped, white plastic vent cover opens and closes with a hand-operated crank. Lowest Prices for the best rv vents and fans from Ventline.

We love this bought 2 for our large food trailer

I have question?
Do you sell a replacement dome?
Unfortunatly we lost one today
Please let me know

Thank you

You mentioned that you were looking for a replacement dome. We do have several available. If it is for a roof vent that is the same as part # V2128SP-01

1. It was easy to order with the Zach's help.
2. It got here quickly
3. Everything came together and all parts were there. (It would have been easier if the knob came unattached )
4. Working great as a ventilation fan.


I went to 4 RV/mobile home dealers in Lake county Florida and none of them had even one of these in stock. I was glad that you had this available to order.


vent and fan unit is good. i added the vent hood covet for protection and to trailer with vent open and love it! seperate purchase looks like a mini roof air conditioner.
i installed into an enclosed trailer so only sheet metal thickness which meant the inner flange would not be used no matter how it was trimmed.
mounting kits available online had sheet metal screws and urethane caulk.
i do not use those and opted for pan head stainlesss steel screws, flat washers for both sides and lock nuts and a good urethane caulk. 3m marine grade is best but hard to get and long cure time for best stuff. i would not do just any silicone but do the best you can get and look at weather to have the time for cure. for example the best caulk is 3m 5200 is marine grade below water line but takes 7 days to cure. i


I bought this fan to replace my AC unit which I damaged going through a car wash which had too low of a ceiling. It turned out to be a blessing in disguise though because the AC unit hung down too far inside the trailer, causing me to be cautious to avoid banging my head. The fan unit fit excellent and came with nice trim. The fan made use of the AC wiring so now all is well. The fan was a good choice and makes for a smoother roof top on my trailer. I use it for dry camping and don't need AC anyway.


Roof vent/fan arrived with no damage and as promised. Installed it tnis afternoon after cutting the hole in the roof...wife not excited about that! Installation was straight forward (13 1/2" square, folks, not 14") and easy to wire up and works like a dream. Wife now excited about that!! Had some issues with the website when I tried to order but a phone call to etrailer fixed that up right away quick and in a hurry! The folks bent over backwards to help this ol' technology challenged swabby get the correct item to fill my need and ordered. Impressed with etrailer the product and their prices. Thank you. And I will be back


What can I say? After many days of searching, I finally found exactly what I needed at Not only is it a great product from Ventline, but no one can beat the price or delivery time. I needed a roof vent with 110V which is hard to find. Found it at at a very low price. I also ordered a range hood for my kitchen in the camper and it just fits perfect and looks really good and I can hear myself cooking....LOL. My old range hood was an old Jenson and it had to be replaced. I highly recommend as they carry many great products at very good prices. I will shop again when I need to replace or upgrade something in my camper. Thanks for the great products.

Hi Robert,Im replacing my AC unit and would like to have a vent with a fan that blows air INTO our RV. As the old A/C hole has 110v wiring I would like to find a fan that uses 110v so I can use the existing wiring to power. Does the fan you bought from etrailer pull air OUT of RV or does it blow it in? I know that this fan is not reversible so I just need to know what direction it works. Thanks in advance for your assistance.
-- comment by: Kelly - 05/27/2015
Kelly....Those roof vents are made to blow out not in. But I am no vent expert, but for some reason I am thinking that if you can make the fan fit backwards and should work. I know that I have taken a bathroom exhaust fan in a house and reversed it put it in backwards it worked for what I needed for. Also try searching the internet for RV fans, NOT exhaust fans. Good luck!!!

Hi Robert, It is crazy how hard it is to find a 110 volt fan for a trailer! I noticed this fan has a very small fan in the corner compared to a 12v fan which takes up the entire space. Does this little fan do a good job of pulling out the heat?Thanks!Karissa

Ordered 110 volt roof fan to put in my enclosed trailer and they where only one that sold this type fan everybody else where 12 volt .They told me the fan would be delivered by certain day and was every thing came just as ordered on time. Would buy from them again.


Product was as expected except for the bent corner in shipping.


We have ordered four RV / trailer vents from ETRAILER, and three have arrived damaged. One was packed at ETRAILER in this condition, the others probably were damaged in transit by the carrier. Then the wrong replacement part was shipped. Staff have been very polite and helpful but their shipping department could use some improvements.

I purchased a Ventline rv vents and fan 120v, installed and works great.


The product was great, but the customer service was OUTSTANDING. Other sites selling similar products have very poor websites, misleading product descriptions and terrible customer service. has it right!


The roof vent was perfect for my application! It works great!

Product is still holding up nicely even through severe weather!
Raul - 12/15/2015


Fast shipping. Installed it the next day, hit the button and it ran great, also I couldn't beat the price. I have a concession trailer so I bought this to pull out some of the heat.


Excellent product. Installed in a food truck to remove heat from flattop grill. Removes heat as intended and helps keep temperature inside at a tolerable level.


Nice product !!!


Fan arrived poorly packaged and therefore damaged with a hole in the screen. Fan itself works well but the surrounding plastics/framing are of poor quality.


We just received it today. It is in good condition and came very quickly. I will not get a chance to try it out until we build our Teardrop to put it in. But it is what we were looking for.


Arrived on time in good condition thanks for your service


Nice Product For The Cost Of Materials


Product was as stated in description and arrived in good condition.

Yes, it works great for a small fan. My wife always steams up the bathroom and this fan helps keep the heat and moisture out No more foggy mirriors.
-- comment by: Rob - 06/19/2015


It does the job. I have it on my van, it's great for days when I need a little airflow but not the a/c.


fairly easy to install (if your handy) and works as it should. very satisfied


Great customer service and product as described and shipped and received quickly!
