Rain Shield


Rain Shield

The built-in rain shield surrounds the vent opening so that you can use it in rain or shine. The shield blocks rainwater and other debris from entering through the vent and damaging the interior of your RV or camper. It also eliminates the need to install a separate vent cover.


Fan Guard


Fan Guard

The fan guard protects your fan from water and debris when mounted on the side of your RV. The guard slides over your vent with the solid end facing up to block rainwater and allow run-off, while the slotted end faces down to allow ventilation. The fan guard also gives you peace of mind with small children around, as it provides the ultimate protection against accidental contact with fan blades.


Push-Button Handle


Push-Button Handle

The push-button handle lets you open and close the lid of your vent with ease - no hand-cranking needed. Simply push the button and push up to open the lid, or pull down to close the lid. Releasing the button automatically locks the lid in place. When the lid is closed, it provides a seamless, low-profile appearance.

Video Transcript for Review of Maxxair RV Vents and Fans - Roof Vent - MA00-03812W

Ellen: Hey everyone, I'm Ellen here at etrailer.com. Today, we're taking a look at the MaxxFan Dome Roof Vent. This is going to have a 12 volt fan and a six inch diameter, and basically, this is just going to be a nice little exhaust fan for your bathroom or shower in your RV. It can be mounted in the roof or in a side wall, so you can either have it vertically or horizontally mounted, and it's just an easy opening vent. To open that up, you just have this little push button on the handle, push up on that, and it opens up our vent to the outside, so we can exhaust the air. Now the fan can't be reversed as far as pulling air in, it's just going to allow air to escape, so it is an exhaust only fan.There's two wires to connect to run that fan, and it comes with an extension, if our walls are thicker than an inch, so we'll have about a six inch extension here to get everything sealed up.

It also has a shield, so if we want to use this in the side wall configuration, you'll mount this so that the solid portion is at the top, and that acts as a rain and debris guard to make sure that nothing can get in there and cause any damage, but also is going to help to prevent any obstructions getting in there and causing a collision with our blades.I'm going to grab a power source and plug my fan in, so you can actually get an idea of what it sounds like, because I know that sound can sometimes be a concern for folks. So there's just again, those two wires to connect. So my ground is going to go to the white wire, power goes to black wire, turn that on, and then there's a push button to actually turn the fan on and off. So you can hear how loud that fan is. Not too loud.

This is kind of a small fan, so it shouldn't cause too much issues there, but it's pushing out a nice amount of air to help exhaust our room, and get that warm, moist air out of our RV, and keep everything a little bit cooler inside there.It does come with the hardware to get everything mounted up, and also the two butt connectors, so we can make our electrical connection for our power and ground. So all in all, a pretty nice compact exhaust fan for our RV or our camper. I'll give you some measurements to think about, to make sure that this is the right fit for you. And the fan itself inside there is going to be a six inch diameter, and that's going to be this inner portion here, the rough cutout.Its overall dimension from this outside edge to outside edge is about eight inches. From the inside portion it's about...

Or the lower portion that would be actually mounted to our roof or our side wall, that's more like nine inches wide. Whenever we have this closed down, it extends up by about three inches tall. Open it up, it's going to sit up above our surface by about three and three quarter inches, so it just moves about three quarters of an inch in travel.It does have a fuse installed, so we don't have to worry about any shorts backfeeding into our RV's electrical system. It's going to be a five amp fuse, and this does work with 12 volt power. Our extension here measures six inches long by six inches in diameter, and then the collar ring that finishes off the look inside there, outer diameter of that is about eight and a half inches.We've also got all the screws that we need to get everything in place.

Now, this kit is available in black and it's also available with an LED lighted interior ring, so if you want to get those, you can find those right here at etrailer.com, and that's again, both available in black or white, and with the LED or without the LED. So check those out if you're interested.But that's going to do it for our look at the MaxxFan Dome Roof Vent. I hope this video has been helpful in determining if this is going to be the right thing for you. Thanks for watching, and we'll see you next time.

Product is well made of heavy plastics. Easy to install once you get over the fear of cutting into your vehicle. Did not hook up to power yet to see how fan operates. Looks good on roof of vehicle.

Review from a similar MaxxFan in RV Vents and Fans


This vent fan helps a lot with keeping my 7x14 cargo trailer cool. Did a lot of modifications with my trailer especially insulating the ceiling and now with this fan makes it better and cooler. The lid is always open to let the heat out because i have the MaxxAir II cover so rain cant get in. Fan runs better with more or bigger airflow from the side vents when all doors are closed so i added the Redline II popup vent and it works great. Fan does not slow down. Im glad i got this and will be purchasing again when i get another trailer. Thanks ETrailer

Review from a similar MaxxFan in RV Vents and Fans


Nice product, very impressed with it’s design, construction, functions, quality and ease of operations. It looks great on my Transit van. Being it’s a medium height roof I don’t want it to be any higher than it has to be. The low profile is nice. The height of van with Maxxfan open is 9 ft. 4 in. The etrailer installation video on the Transit was very helpful. I made a frame just as described on the video. Using the 2 x 2 ft. piece of 3/4 inch plywood to make the frame is the way to go. It provides the strength I needed due to the weight of my solar panel bracket just 3 inches away. The two screws you see near the edge of the frame is the solar panel bracket. A constructed picture frame style frame would never support the weight. It is a strong solid frame. The roof is solid.


Comments
Maxxair after 1 year is working great and looking good. I didn’t. Mention in my original review that I have it powered by my solar batteries. This way there is no problem with draining the truck battery. I can leave the van locked up and windows closed and exhaust the heat for hours when away exploring.

Review from a similar MaxxFan in RV Vents and Fans


I love these fans. When I bought a caravan I removed the fantastic fan for one of these because it can be left open when it rains....I rarely ever closed it just so I had airflow in the caravan. Now I have a van, installed it for the same reason. Expensive, but worth it in the long run. I wish they offered a non translucent top model.


Comments
A yeah later and it still is the best thing I did to the van for increased comfort...next is solar

I use my van for construction as well as camping. I wanted an all weather fan to keep it more comfortable. I just installed the MaxxAir fan today and so far is seems great. I followed the install video for my Nissan NV2500 on etrailer.com and everything went perfectly. The only thing in did differently was use pvc board instead of plywood for the pack out material. It looks great and functions great. I would highly recommend this product.

I have used etrailer for years and continue to be impressed with their products, support and reasonable pricing. Recently installed a MaxxAir vent fan in my high top van and it is a fantastic fan. Great quality, quiet and powerful! Highly recommend etrailer and this product

Review from a similar MaxxFan in RV Vents and Fans


We ordered and DIY-installed two of these MaxxAir fans to replace ineffective and aging vent fans in our 5th wheel RV. Installation was straightforward using the easy-to-understand instructions. All the necessary hardware is included, although you'll need some butyl tape and self-leveling sealant to complete the installation on the rooftop. We love the ease of operation, the relatively quiet 10-speed fan, and the ability to use the fan even during a rain. The mounting bracket that fits the 14" roof opening is a one-time install, meaning that you don't have to tear into the roof and sealant again should you ever need to replace the fan and cover unit with the same or similar model. I agree with all the other positive reviews I've read about this product.

We still love our MaxxAir fans!

Site could use one or two filters to help customers decide which unit to purchase. There is a large number to browse through. Purchase was easy. Unit properly described, shipping boxes were well packed. Unit installed easily, due to etrailer's how to install video. Happy with purchase and easy of installation. Will buy from etrailer again. Thank you.

Purchased the Maxxair Fan for a Ford Transit camper conversion and after 6 months on the road I wouldn't have gone with anything else. It's easy to install, easy to use, and I've had no issues at all with it. Etrailer was also quick to provide support when / if I needed it!


Comments
Still working just fine after another 6 months on the road and using the van as a daily driver. Ive noticed some dust eventually builds up on the blades of the fan, but its easy enough to use a wet cloth and wipe it down. Fantastic product.

Review from a similar MaxxFan in RV Vents and Fans


The vent installation went very well. The video on etrailer was helpful. I added aluminum reinforcement flat bars to the top of the mounting flange to improve the stiffness of the sheet metal roof. The Sprinter van has a flat area to install the fan without having to build up a mounting surface. I used stainless steel Philips head screws and nylocks instead of the provided stainless steel screws. The black wire on the fan is the positive lead which is not a standard 12-volt wiring color.


Comments
It is an excellent fan and I have had no problems

I purchased this maxxfan to replace the roof vent unit that came on our camper. This new vent fan is whisper quiet and best of all it can remain open while its raining. The install was easy and it fit the original hole perfectly. Used the TremPro 644 sealant also sold by etrailer and the install came out perfect. Thank You! etrailer for quick shipments and quality products.

I installed this fan in a home built camper that I filmed while building and posted the entire build on You Tube. The fan has help up perfectly and on low speed it will run a very long time with out recharging the battery. I have built five of these small campers and four of them have been equipped with this fan.

These MaxxFan rv fans are superb! Installed when we rehabbed a decrepit RV, they have held up wonderfully. We got rid of the cooking vent, thus giving more space in the kitchen, and our MaxxFan nearest the kitchen is our vent. You can see pictures and even a video of the fans and remodel on our blog yippikiyo.com etrailer is our #1 source for quality and price for our RV and other trailers.

Still loving the fans. Very easy to clean screens. They can move a lot of air.

Review from a similar MaxxFan in RV Vents and Fans


This is my second Maxxfan for my van! why two fans on my van? it's a 2017 GMC Savana cargo van and the curvature of the van is to much for most add on windows and the ones I found that would work I didn't like so a second fan was to let more ventilation in . You can leave the fans open even in the rain and they have 10 speeds for intake or exhaust.


Comments
Good, I have two of them I installed in my cargo van do to no windows that open in the back. We have had some good rains and with the vents open NO Leaks. The video on etrailer were very helpful.

Review from a similar MaxxFan in RV Vents and Fans


Just got it installed, works great! I had to do some modifications to the roof because I didn't pay attention to the 2 inch minimum, overall not a bad install process. etrailer was quick and had excellent service as always.


Comments
We typically dont need AC, so this fan has been a perfect option to get air flow in our truck camper. An added benefit is that we can put up and take down the pop-up without having the door open to bugs or having to manually tap in the canvas. An excellent addition to our rig. Install was pretty easy, the hardest part was getting the electrical service from a light fixture.

Review from a similar MaxxFan in RV Vents and Fans


I've had the fan in for a season, and a couple southern road trips. Generally happy. It will run "all night" with no problems on the stock dual batteries in my Ford Transit passenger van. Didn't spring for the remote and maybe would the next time. the controls are bit small, hard to reach, a touch confusing for groggy, middle of the night changes. Fan is quiet and efficient but even on high, directly over the bed, it's not going to bath you with sweat drying air movement. Quality seems good, I installed with an aftermarket, designed for the transit roof profile, ring, it went well. I painted the interior trim with gray "for plastic" rattle can paint to match the Transit ceiling and that is good stuff, it held up well to multiple on offs while getting the install just right". I also brush painted elastomeric white roof coating over the exterior caulk and and mounting screws, zero leaks so far.

Review from a similar MaxxFan in RV Vents and Fans


I purchased this MaxxAir MaxxFan to replace a stock vent/fan that came on my teardrop camper. The most important thing to me was that the fan was quiet as it is only about 4 feet away while sleeping. This fan is so quiet that I can barely hear it on low and on high we can talk in normal tones and hear the television over it just fine. With the stock fan on we could not hear the TV even with the volume at max and could barely stand to leave it on while sleeping. The sleek profile actually adds style to the teardrop. My second hope is that it moves enough air that we won't need to use A/C - so far so good, this fan moves so much air that my curtains go sideways (and can still hear crickets outside) and the 10 speeds let me get it just perfect. Auto on at 78 degrees, reversible, ceiling fan... all nice bonuses. 100% satisfied with this product - Follow the directions, install is relatively easy, solid product. Hardest part for me was correcting the original opening which was not square. I used an oscillating tool to cut the inside shroud down, it was pretty quick but left some cleanup, not sure if it was ultimately any easier than using the prescribed hacksaw.

My backyard Tuff Shed workshop has a turbine vent fan, which really doesn't work all that well. Over the years I've tried various powered fans, but have never been satisfied with the results. Now that it needs a roof, I was thinking about a solar roof fan. Since I have a 400 watt, 12 volt solar system for security lighting, I realized I could use a fan similar to the one in my RV. The installation was very easy, and the quality of the fan is excellent. Not having to worry about closing the lid for rain is great, and the automatic thermostat is a wonderful set and forget feature. I'm especially impressed how quiet it is.

  • How To Install MaxxFan Dome Roof Vent On Thin Metal Roof
    The MaxxFan Dome Roof Vent part # MA00-03812W will work just fine on passenger vehicle with thin metal roof as many others have done so as well. That said, you will need to add some material like plywood between the roof and fan to get the required 1" of thickness to mount. In regards to cutout size, this will be 6-1/2".

  • Recommended Replacement Bathroom and Kitchen Vent Fans for Sunnybrook Scout Trailer
    It looks like you've got a standard roof cutout that is roughly 14" x 14", so for the bathroom I recommend using the MaxxFan Roof Vent w/ 12V Fan - Manual Lift - 4 Speed # MA00A04401K which has 4 speed settings. If you're looking for something with a powered vent lift, the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan - Powered - 1 Speed - Black # MA00-03851 is a great option. For the kitchen fan you could use one of those fans above, or you could use the smaller MaxxFan Dome Roof...

  • Does Interior Light Give Enough Power for the Solar-Power Plumbing Vent Fan # UF53-945001 to Run?
    The Ultra-Fab Solar-Powered Plumbing Vent # UF53-945001 is a good option for applications needing a small amount of air displacement like RVs or motorhomes. According to my contact at Ultra-Fab, these will only work with sunlight and won't receive power from any type of interior lighting. Unfortunately, we don't have any other solar-powered options that would work for your application. You could use something like the MaxxFan # MA00-03812W, but this would need to be wired to a 12V power...
