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 ??.

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

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.



by:

Great for tight spaces. Not the most flashy of designs, but they work well. Lower profile than the maxxair 6 inch round fan. Easy to work on when it comes time to needing to replace the fan motor as well.



by:

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.

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.



by:

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.



by:

Fan arrived quickly and was an exact replacement for our Hail storm damaged unit. Thanks eTrailer!



by:

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.



by:

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



by:

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.



by:

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!

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.

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.



by:

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

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



by:

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



by:

This was a very nice upgrade to our camper bathroom. It did not have a vent and I didn't want to cut a big whole in the roof. Nice and quiet, easy to install, and easy to use. I also really like that it lets some light in as the plastic is sort of tinted.



by:

This is a cost-effective alternative for confined space or limited access areas - we installed two in a sprinter conversion, one above the shower and one over the bed.
eTrailer shipped in good order - very happy with the purchase.



by:

Arrived on time as usual, installation was a breeze, it is perfect for our small trailer.



by:

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.

  • Can Direction of Air Flow on Ventline Vanair Trailer Roof Vent Fan part # VP-543SP be Reversed
    We've spoken with Ventline and if you reverse the polarity of the wiring on the Ventline Vanair Trailer Roof Vent w/ 12V Fan part # VP-543SP you can reverse the direction of the fan. If you wanted a switch to change the direction you'd need a DPDT switch found locally at a hardware store.

  • Is Passive Inlet Vent Needed With Ventline Powered Vent in Camper Shell?
    When installing the Ventline Vanair Trailer Roof Vent # VP-543SP a passive inlet vent such as # HMAV2-AVT2 certainly would not hurt though it is likely not necessary, though it would be difficult to say for sure without knowing the rest of your ventilation, the size of the camper and how much condensation you are likely to produce. In regards to your question about the spacer, you are correct that a spacer will be needed for the thin camper shell. I've added links to video reviews of...

  • Ventline Vanair Trailer Roof Vent w/ Fan # VP-543SP for Box Truck
    The Vanair Roof Vent with Fan you referenced, part # VP-543SP was originally designed for use on conversion vans, so it should be a great choice for your box truck. The vent will install into a 6-1/4 inch diameter rough opening. The garnish (or inner trim ring) allows the vent to be used on roofs of different thicknesses. Since your roof is so thin, you might need to trim some of the length off of the garnish which is fine according to the manufacturer. The installation kit which includes...

  • How To Install Powered Roof Vent Fan On Promaster Van with Thin Metal Roof
    In order to install the MaxxFan Deluxe Roof Vent part # MA00-07000K on a van with thin metal roof you'd need to use some sort of brace between the garnish which will provide support and help secure the base. The type of base can be pretty much anything you see fit such as some spare lumber. There is also the option of a smaller powered fan, the Ventline Vanair Trailer Roof Vent part # VP-543SP which is more commonly used in these types of applications.

  • Roof Vent To Fit a 6" Hole In The Roof Of a Sprinter Van
    The Ventline Vanair Trailer Roof Vent w/ 12V Fan # VP-543SP is going to be the closest vent to fit that 5-1/4" hole in the roof of your sprinter van. This vent is designed to fit a 6-1/4" opening so you will need to remove a bit more from the hole. The 12 volt fan only uses 1.5 amps of power and can circulate 100 cubic feet of air every minute.

Since you have a larger diameter hole currently what you could do is get maybe a piece of sheet metal that is larger than your opening and cut the smaller 6-1/4 inch hole in it for this to attach to. Or if you don't mind opening the hole even larger you could cut a 14-1/4 inch by 14-1/4 inch hole and install a roof vent like the part # V2092SP-28 which is a standard...

The mushroom vent does not have a fan built in so no wiring or switches are needed. An option for a roof sewer vent that does have a fan is the Ultra-Fab Solar-Powered Plumbing Vent # UF53-945001.

Though I do recommend closing this vent in the rain, you can add ventilation by installing a vent on the sides of your van.

  • Adding Vents to Cool an Enclosed Trailer for Transporting Honey Bees
    First of all there isn't something specifically designed for this. Your trailer is going to get extremely hot during the summer months.

You can use ring terminals or butt connectors or something else if you have a favorite type of connector. On your Ford work van, since the roof is just sheet metal there will likely be some gap.

  • Does Fan Air-Moving Capacity Change When Fan Wiring is Reversed to Operate in Opposite Direction
    Reversing the polarity of the wires to the motor on a fan will certainly let it operate in reverse direction. Whether this reduces the amount of air-moving capacity in cubic-feet-per-minute (CFM) depends on the nature of the fan blades. Most fans, including the Ventline Vanair # VP-543SP, have fan blades that are oriented in a specific direction because their primary purpose is to exhaust hot air out of the trailer. It is absolutely safe to wire the fan in reverse polarity - I confirmed...

  • Switch to Reverse Polarity On Ventline Vanair Trailer Roof Vent w/ 12V Fan
    You certainly can wire the fan of Ventline Vanair Trailer Roof Vent w/ 12V Fan part # VP-543SP in reverse polarity. I confirmed this with my technical contact at Ventline. Please note however, with this fan the air-moving capacity will be reduced to some degree. You will want a DPDT Center Off Toggle switch to accomplish this. Ventline does not offer such a switch, but you will be able to pick one up at a hardware store.

  • Vent Recommendation for Trailer with Fan
    If you have a 14 inch by 14 inch Ventline roof vent on your trailer already a better solution would be to go with a powered unit with a fan like the part # V2094SP-28 to replace what you currently have as the part # UF53-945001 can not be installed in place of it. If you happened to have a # VP-543SP instead the # UF53-945001 would work as a replacement.

The fan will only work when you have solar charge which can work even on a cloudy day, but obviously would be covered if you had something on the roof rack obstructing it.

    I would not recommend leaving Ventline Vanair Roof Vent with Fan, # VP-543SP, open when traveling down the highway because the fan and electric motor would be exposed to the elements. You would not want any dirt, rain or any other type of debris to get inside of the vent and ruin the fan.

    You could use a rheostat to control the electric motor in Ventline fan # VP-543SP. It is designed as an on/off device but I don't see a reason that it couldn't be controlled. You may end up with that buzzing sound that occurs when electric motors are not getting the voltage they need. That could end up being louder and more annoying than the fan. The solar powered van, # UF53-945001, might be a better option. It would be quieter but wouldn't move as much air.
