replaced older unit much quieter..thks
Product was just installed. Was very easy to install and works very well
Top of the line!Shipped fast, and I like all the follow ups. We'll have to wait and see about product reliability, although it feels and looks like it is built well.
Arrived speedily! Fit perfectly, was as advertised! Very Pleased with the whole transaction!
Vent arrived quickly in great shape. Price was excellent. They upgraded the shipping as well!
Arranged for installation by local Camping World.
This was for a full replacement (same fan, from 1996) of the shower vent fan in our Airstream B190 camper van. We needed a minimum of the screen, fan blades and top cover, so I figured let's get it all. Once I cut away the old caulk, reassembly was fairly easy, being careful on the ladder. As in previous transactions, etrailer ships quickly, and their pricing is hard to beat.
Received the item in record time. Easy installatio instructions
this vent made it simple to install a power vent in my ice fish house trailer to exhaust fuelms after drilling the holes in the ice.
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.
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.
Exact replacement for vent on my 2006 Gulfstream class "B". Mounted using existing holes. Was originally told item was on backorder but received shipping confirmation same day order was placed. Delivered two days later. Outstanding customer service, competent and knowledgeable staff. Would most definitely recommend etrailer.
Fan is a good replacement. It works well. But I do think the screws to install it should come with it. I do not want to pay $66 for butyl tape, sealant and screws (the sealant and tape I already have). Other than having to use the old screws, I’m happy with it.
Fan arrived quickly and was an exact replacement for our Hail storm damaged unit. Thanks eTrailer!
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.
The installation was easy, the fan does a great job. Thanks
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 ??.
Ordered two - one was not packaged in original packaging - had a couple of cosmetic scratches on the trim - received replacement -
Thought that if your going to send an open item you should let the customer know in advance - service was great as always.
If it lasts as long as the original one that was installed in my custom made sleeper on my 1980 Peterbult I will be very happy and it shows no signs of not lasting as long as the 1st one installed it a Double Eagle sleeper from Shipshewana Indiana
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.
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
The fan moves a lot of air and is quieter than the original. Can't ask for much more than that.
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.
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.
Great pricing, quantity product and delivered in a timely fashion. When we need something for our van this is the first place we look.

I am using the solar-powered plumbing vent for an outhouse at my camp. This vent works continuously with whatever sun is available. I am very pleased!
I bought this item for a snowmobile trailer to remove heat during the summer. I have yet to install it, but it seems to spin quite fast. I felt it would work a lot better than just one or two plain air vents. Heat builds up fast in a black trailer. I only purchased one, but would recommend two or more for larger trailers. This is solar powered so once it's installed the Sun does all the work...

Thanks for the no-hassle quick replacement.
I have installed these vents on two 7'x14' trailers that are used to store kayaking gear (boats, paddles, helmets,PFD's,clothing and other soft goods). Hoping that the constant air-flow will help prevent mold & mildew. I can already feel the difference in temperature (cooler) than prior to installation. They work, but the construction is so lightweight, I'm wary of how long they'll last. For $[XX], it seems they could construct them a little beefier.
We have a Suncast storage building and it was beastly hot inside on sunny days so I put some foam insulation between the inner and outer surfaces and installed 2 of these just below the ridgeline of the roof and they are working great. There is absolutely no noise what-so-ever. While they have a limited volume it takes the hot air out allowing cooler air to enter through the normal vents. Great deal for the money and now we will see how long they last making the value even better.
I installed the Ultra-Fab Solar-Powered plumbing vent sold by E-Trailer on my 13 ft. Scamp trailer to circulate and vent air in the trailer while it is being stored. There is indirect sunlight incident to the solar-powered vent that shines through some pine trees. The vent works perfectly. I installed a 4-in. air conditioner duct (sold by etrailer,Valterra Heating And A/C Vent Register) with built in flappers to regulate the air flow thru the solar-powered vent and to make the appearance of the vent look better from the inside of the trailer. Also made a trim ring out of a plastic cutting board to garnish the solar-powered vent inside opening. Look great and works like gang busters.

I had to replace the solar powered vent after one year of service. It was no longer operable. I took the malfunctioning vent apart and found that the seal at the solar panel directly above the motor had failed and permitted water to damage the motor. I installed a second new solar powered vent and took the time to place additional sealant between the solar panel ant its mounting plate.
I am an Rv'er, but actually installed this outlet/exhaust fan on top of my shed. Living in S. Georgia, it gets quite hot and humid, and this thing has been spinning non-stop all year round. I sealed the circumference with all weather silicon as I bolted it down. Outstanding device, and I'll probably get one for my toy hauler as well!

Its been over a year and a half and that little fan is still moving strong, even on overcast days!
Installed this on top of my 8x8 shed for airflow and ventilation purposes. I've had it for a year now and it still runs almost all day. Sunny or even overcast skys will have it humming along. I was concerned with the plastic blades becoming brittle and not being able to withstand the highs and lows of Michigan's climate, but no issues thus far. I recommend this for a solar powered shed roof vent, but cannot give a review as to its intended rv venting capabilities.
I didn't use my solar vent quite as intended. I mounted it into the top of a modified Rv roof vent (which I keep closed typically).
This is a replacement. The first lasted about 5 years but ultimately the plastic degraded in the sun and became brittle. I assume this will do the same over time. We shall see.
Works as intended. Keeps a little air flowing through the rv. Wish there were bigger solar fans for this job.
Ordered to replace my worn out solar vent fan. Quick shipping!

A year later and the vent is still performing as expected. Haven’t had an odor in the unit since I installed this vent
I used this roof mounted solar powered plumbing vent to exhaust excess heat from an enclosed 5x8 trailer. The inside of the trailer remains somewhat close to ambient temperature
I installed this vent on the roof of a 6x12 cargo trailer. It worked well right out of the box, even during a cloudy day. Other reviews suggested adding a screen to keep insects out and so I did. The trailer will sit out in the hot Florida summer sun, and when I return later this year, I'll post an update on how well it performed. So far, so good.
seems to work as described. Does take a fairly bright sky to work...but not necessarily direct sun. As an FYI, fan was not on shaft when arrived. After I figured it went on with the embossed arrow showing rotation so that it could be seen, I firmly pushed it on the shaft but it was noisy when spinning. I pulled it back just a tiny bit and it ran noiselessly. Installation went smoothly. I did have to cut about 2 inched off vent pipe so the the fan did not hit the pipe. I also removed the 3 screws to separate the base from top (fan and solar panel) to make the base easier to install then reattached after base was fully installed.
These little solar vet caps Work just fine!
None-the-less, For all my PVC/ plastic roof top covers they fall victim to squirrels! The refrigerator Vent cap alone has been replaced 3 times in about 9 years.
I put this on my Trailer where i store my scuba equipment, needed to let the moisture out, works great. Will probably order a second one for volume because of the size of the trailer. An added benefit is it functions as a skylight and lets in Light as well.
The low profile of the vent met my immediate needs. You cannot hear the fan running so unless I climb up on top it's a matter of faith. You cannot turn it off either. While it may be ideal for a backyard shed it's not a real improvement over a standard rv vent. No regrets on buying it but probably wouldn't buy another.
Mixed review, bought two of these, installed them both on my enclosed trailer, to help vent it. One of them stopped working a month later.
Found these at the local trailer place, except they were way overpriced!
I replaced the entire roof with metal roofing and these were the only ones that would fit between the ribs.
Haven't installed yet, but the customer service so far has been TOP NOTCH! with extremely quick shipping and great follow up to ensure my satisfaction.
Recommend this site, keep up the great work!
So far so good. We just hope the fan will operate for years to come. Just a little light on the solar panel and the fan starts working. Looks to be very good quality product.
We have 4 of these units in service for going on a year now and only one has had any problem. One of the motors had the front end bearing/bushing fail and the unit made a ticking sound when the fan would wobble. The one issue I had a problem with was that when I ordered another to have a spare on hand I found the price had increased from that of last year. While we generally expect that prices will rise over time, having been following solar for a potential solar addition to our home I was otherwise finding that solar was going down in price as the technology was improving so that was a bit of a surprise but overall I believe they are still a good deal for the money.
Great idea, poor quality. Worked fine for about a month before it began making spinning noises. Obvious that fan was becoming loose on it's axis, possibly from cheaply designed mount. Lasted about another 6 weeks before it stopped working completely.
These should not be a disposable item, and climbing a ladder every 2 1/2 months to change a vent is not an option.
I would NOT reccommend this
Pros: Well made, good ventilation. Cons: Take a very bright light to make it go. It will only work on a clear day with direct sunlight.

I am amending my review. After further testing I found it does work with overcast skies. 5 stars.
Installation was ok. Had to lower the existing pipe (hit the fan) and had another vent pipe close so had to trim the new one around the outer edge. As soon as it hits the sun it turns on. Would recommend it to anyone trying to remove more of the black tank smell.
Runs so quietly that it's hard to tell it's working. But I installed it on the top of my small trailer, where temps had soared to 119 Fahrenheit, and now the temps are much closer to ambient.
You must replace every two years because the murder stopped working

This unit was an exact replacement for the Escape installed vent that was destroyed by a freak hail storm. Still working great.
