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.

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. 680545

Review from a similar MaxxFan in RV Vents and Fans


The Maxxair Deluxe fan works better than expected. We ordered the version without a remote and are extemely happy with the product. It took me a while to get around to putting it in my motorhome as I thought I would have to fish wires through my ceiling insulation, but when I remove the vent (with no fan) there were wires for the 12 volt lights already passing through the opening. Some YouTube videos warned against using power to your lights to power your fan since they are switched. Each light in our motorhome has its own switch in addition to the switch up front that controls them all. I just have to leave the main switch on and turn each individual light off. We do that anyway most of the time so it worked out fine. The vent fan was pretty easy to install and I am not the most handy person you will ever meet. As always the fine people at etrailer were friendly and helpful and they have at least as good a price as anyone and better than most. Very happy camper. 497875

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. 716294

Review from a similar MaxxFan in RV Vents and Fans


Purchased to install in fifth wheel bedroom, where no fan existed, just a roof vent. Most time consuming was removing the old vent. The caulking removal was a real labor intensive operation. The factory must have used a fire hose to apply the stuff. Once the vent removed and the caulking mostly removed, the install of the maxxair went pretty smooth. Putty tape (purchased from local shop) under the rim, several stainless screws (15), came with fan, then finish roof top install with self leveling caulk around rim and on screw heads. Inside had to tie into 12v wiring at bathroom fan and fish wires to bedroom vent hole, less than 4 feet. Made connections, put on interior trim, and now wait for next RV outing to test efficiency. Works great in driveway. And one more thing, I also installed a Maxxair II vent cover in black. Helps to darken bedroom along with protecting vent. 279793

Review from a similar MaxxFan in RV Vents and Fans


It's been a year since we installed our first Maxxfan Deluxe Vent W/ 12v Fan - Manual - 10 Speed - White.... 1) It wasn't too difficult to remove the old fan and install the new one. Took a little patience with the first install, but by the third (we have three fans) it was a piece of cake. Don't forget to use Decor to ensure everything is sealed properly. 2) These fans are very powerful. The one in my bathroom will actually suck the door shut. When we set the one the living area to blow air in and the one in the bedroom to blow air out, air really moves and cools down the rv fast. 3) They are way more quiet compared to my old original fans. Only when I have them on the highest setting to I notice they are on. 4) The built in rain vent is very useful given that if it is raining the only air we get is through the fan vents as all the windows must be closed. 4) My only disappointment has been with the way the fan blades are designed, the air moves more sideways near the ceiling (which is good as hot air rises) but when it is really hot and I'm lying in bed I would like the air to blow downwards so I can feel it. 558588

They still work but 2 out of the 3 fans squeak at low speed.. which I feel is a little premature for only being a year old. When really they started squeaking at 6months. All in all they do a great job of exchanging the air in our rig.. 719771

Xcellnt Vent - Installed my vent a yr ago (long story), but only made it operational 10-2018, so I Very much like that it's manual, so i could open/close it without power. Best feature, dual lift arms. Able to drive with the vent open without the lid flapping "Very Stable". A great "Basic" fan vent without all fancy stuff like Rain Sensor, Thermostat, Variable Speed, like my last one that ends up not working after parts are no longer available. 4 speeds is enough. It's Quiet. Lifetime Lid Warranty "Awesome", my last one spider cracked from UV. Only option I'd like to see is "reverse". Doesn't feel like it's moving much air with the lid closed but I have not as yet used it as a ceiling fan to circulate heat. If it does it will be the perfect vent. I will be putting it to that test in the coming months so the jury is still out on that one. 583861

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. 662099

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

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. 634921


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 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. 561667

Installation was easy and simple. As long as you seal it correctly, you’ll love this product. I installed it in a back room of my 34’ tag-along. Kids were complaining that it was stuffy and no air flow. I did about a weeks worth of research and product research and found this product. It works wonderfully! We primarily use the exahust function. With the integrated rain shield, you won’t have to worry when it’s raining outside. I was a little disappointed in the distributing service from eTralier. I was initially told that the product was not in available stock and the item had to come from the distributor. After about the third e-mail notifying me of the same delay, I called and expressed my disappointment. I received the product 2 days after that phone call was made. 443611

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. 547600

Nice fit, very powerful, very adjustable, and much quieter than the unit that it replaced. Appears to have an option for a winter cover, based on some additional female sliding holes of some sort? that I know nothing about. 453835

Gregory, Thank you for your review. This Maxxfan includes molded mounting tabs to install a FanMate vent cover. The FanMate part 955003 slips over the molding tabs and clips on to provide superior rain protection.

Nicely engineered unit that, with Maxxairs' thorough instructions, installed without difficulty. A nice addition to our fifth wheel... Equally important, the service from etrailer was top notch, the product was in stock, was shipped quickly and was priced competitively. We'll be back... 643823

Not really happy with this product. Expensive fan that will not run for three minutes without turning itself off. Called the mfg , they said bad board they sent a replacement board , worked great for a week now it is back to turning itself off again!!! Not etrailers fault , just a sorry & expensive piece of junk. Wish i had bought the fantastic fan instead. How hard is it to build a 12 volt fan???? 552948

  • 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...
