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


Comments
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 ??.

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!

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.

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

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

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.

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.

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.

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.

Received item via UPS late pm on 11/9/17. Installed it yesterday pm. Took approx. 2 hours to complete project. Took much longer to remove old ventilator than to install new one, as the old one was original on 35 year old Air Stream. Perfect replacement and works perfectly. Those that order this need to know that there is NO hardware included and you should use stainless steel screws to mount item onto trailer for long term use. These are available at any [local hardware store]. Very satisfied customer.

Bought and installed in an E350 when I converted it from a cargo van into a camper. Pros: - Small, slimline, unobtrusive. - Simple open/close operation. - Simple ON/OFF button. Cons: - Unit arrived with internal power cables tangled in the fan blades - had to disassemble and zip tie to make good. Customer service thought this wasn't a big deal although I wasn't expecting to make repairs on a brand new product. - Fan is very noisy if you try sleep with it on. It creates quite the rattle, most likely from the imbalanced fan blade assembly. - The waterproof seal that keeps wind/rain out of the van unglued within 3mths, had to purchase a replacement.

Definitely don’t install above your bed!! This thing is garbage, and it leaks (a lot)... somehow water gets up under the cover and pools in the screen before dripping through and making a nice puddle in your rv. Fan does not pull out any air. Absolutely no appreciable difference when it is on. It just makes a lot of noise. I even reversed the polarity as an experiment and it doesn't seem to pull OR push any air into my van even in tandem with a Maxxair fan. Strangely, if I turn on the fan with the vent closed that's the only time I can feel a very slight breeze and it's the same exact thing, a very slight breeze, if I reverse the fan blade :/ Also, it slowly works itself open when driving at speeds of over 50mph and will not stay down. Hole in roof for nothing...!

Haven't installed yet. Will be adding to my 5x8 RV trailer. I just spent 4 nights camping in rainy weather and found I need better ventilation than just side windows. This looks like a good add on for me when paired with a vent fan. Conveniently bought a Ventline Ventadome Trailer Roof Vent with 12v Fan at the same time as this pop-up vent. Will install the pop-up vent in the rear wall of the trailer and the Roof vent at the front. These two items together should keep the trailer ventilated for both Air Conditioning and Electric Heating without allowing excess moisture or rain through the windows. Only gave 4 stars because I haven't yet installed these items.



- VP-543SP

Ive bought 5 of these and only one is still working. The failure I think is due to a foam seal that eventually falls off and gets wrapped in the blades and wears out the motor. When I replaced the fan with a new one the foam seemed like it would not come off again so I left it but after a few months in the heat it did the same thing. As far as warranty goes I’d be responsible for shipping it and if they deemed it faulty on their part it would be covered. I elected to not bother. I haven’t seen a better product so I will probably repurchase myself but currently its just a vent.

  • Roof Thickness Requirement To Install Ventline Vanair Trailer Roof Vent On Enclosed Cargo Trailer
    The Ventline Vanair Trailer Roof Vent w/ 12V Fan vent part # VP-543SP is designed for roof 1-1/2" to 2-1/2" thick. The vent is designed for enclosed trailers so you shouldn't have an issue installing it on your aluminum roof as long as it's 1-1/2" thick. It also requires a 6-1/4" Diameter cut out and a 12V power source. A lot of customers use these vents on truck bed campers and aluminum enclosed trailers with thinner roofs.

  • Installation of Ventline Vanair # VP-543SP onto a 2017 Ram ProMaster City cargo van
    Typically, folks will use pieces of lumber to frame out the interior of the rough opening which makes for the proper thickness. I'd probably cut some 1/2 inch plywood to the necessary shape and glue three thicknesses of it together to gain the necessary thickness. The vent fan was designed to exhaust air from a small camper or van. The unit features a 100 CFM fan.

If you continue to use the fan without the foam ring you would be subjected to leaks which could then short out the motor.

  • Replacement Bathroom Vent for Philips/Ventline V2065 Bathroom Exhaust Vent in 1992 Schultz Trailer
    Since your trailer's original bathroom vent fan is now 25 years old its motor could very well be past its useful lifespan.

As such the curvature of the roof in the area where you mount the fan will not be a factor. This fan has numerous diameters depending on where you are measuring. Luckily another Expert took a bunch of these measurements and I have included a picture showing them for you.
