Video Transcript for Review of Ventline RV Roof Vent - Low-Profile Round Fan - VP-543SP

Today, we'll be taking a look at the Ventline VanAir Trailer Roof Vent. This is going to give you a nice, small, low-profile vent option for your enclosed trailer and those places where you don't really want to have a larger opening for a bigger fan or you just need something small with a nice, low-power draw, like this.It requires a 6 1/4-inch rough opening to get this installed. If I flip it over, we can take a look at how it's going to operate. We'll have this little handle portion here. That's what's actually going to raise up the cover, so when it's installed, you'll push that up, and that'll raise the vent up as well. It's a little harder to do with it not actually installed.

Push that up. There we go. Now, our cover pops up and that allows air in and out, and then our fan can also operate. It has a little button to power that on and off. Turn my power source on here, and now, our fan will kick on.So, even though this is fairly small, it still puts out a good amount of air to circulate our trailer, keep it nice and cool in the summer, let out any odors or anything like that.

And flip our switch again and it comes to a stop.This has a fan power of 12-volt DC, with 100 CFM. So, it's going to take a very low demand on our battery. It only draw an amp and a half, yet it still moves that 100 CFM, or cubic feet per minute. So, it's a pretty good amount of air that's going to be moving in and out of our trailer.The cover on the top is translucent. It's a little hard to tell on camera, but it does allow some light through.

It's pretty quiet operation. Again, if we pop our sleeve off, we'll be able to sit that fits that 6 1/4-inch diameter. It doesn't come with any hardware or sealant, so you will have to pick that up on your own, but we do have a kit to get that installed. That installation kit is RVIKIT100. You can find that here at etrailer.com.

That's going to give you all the screws and sealer to install that vent in place.Whenever we have this installed, it's going to extend above the roof by 3 1/2 inches when opened, and then when closed. Pull that back down. When closed, it only stands up about 2 3/8 inches. Does come with our shroud there to cover up the hardware. Just need to line it up with the wiring opening. We only need to connect it to power and ground to get everything connected there. So, we'll have our two wires; black for power, white for ground. You'll also need to pick up some butt connectors for that. I would suggest using some heat-shrink butt connectors, just to make sure you have a nice watertight seal on those. The cover is kind of a smoke color, sort of a darker. almost a dark green. And it does come with a one-year warranty from Ventline.And that's going to do it for our look at the Ventline VanAir Trailer Roof Vent.

The fan arrived in a timely fashion in new undamaged condition, was east to install. Very happy with my purchase. 699634

Perfect replacement for the original. When in without a problem. Well made still runs and quieter than the original. Will do business with you again. Thank you. 698369

I haven't really used it enough yet as we are still working on inside of Van. I do notice I would like the vent to be 2-3 inches bigger. I like the style a lot. Would like it to be made of stronger material. 681021

Great weatherproof ventilation solution. Good air flow and simple install. 730176

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. 543685

I appreciate the efforts by NickyK on my behalf to arrange the order and shipment so professionally. It was easy to work with your company and I will do so in the future as my customers have other needs for your type of products. 710591

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. 451148

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. 548226

Works just like it is supposed to work. Easy to install, runs quietly. First replacement of one we used for 20 years. 519811

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. 24341

Needed to replace an older model of this item. I was surprised to see that this was almost all plastic with a very small motor, compared to the metal housing and more substantial motor on to older model. Installation was simple, fit perfectly in old installation hole. Items works well.... 294760

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. 254197

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 ??.

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. 93184

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.

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 228520

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.

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! 155878

Been running 365 days later with flawless operation

Works very well. Was a direct replacement for our original one that was 23 years old. 771221

- VP-543SP

Solid build quality, simple to use and install. 766098

- VP-543SP

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 764766

- VP-543SP

Matches the original from my RV perfectly, and appears to use *much* better plastic for the fan blades. Only drawback in the original and this design is the use of rivets, which make it difficult to replace only the motor and fan blade. 732960

In the past 2 years we have purchased 3 of these fans. Excellent quality. One was to replace an old fan in our 1978 Avion 34, the other 2 I installed in our sailboat. One for the galley, the other for the head. 703821

This product is the exact match for my Airstream Interstate. Local install was 30 minutes. Etrailer has been awesome for all my RV needs. Fair prices and great customer support. Frank Higgins 683611

Excellent service. The exhaust fans work very well. I've bought lights from you in the past, never been disappointed. Thank you 682722

- VP-543SP

Haven't installed yet. Looks like a good product bit has limited instructions. Built for a much thicker roof/ceiling then on our fiberglass egg camper. Will have to do some modification or create a spacer on the inside. 679951

EXCELLANT!! I received my products in good condition for exactly what I had ordered. Thank you for a job well done. 679253
