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.

Installing this in the bathroom ceiling of our motorhome was pretty straightforward if cutting a hole in your roof doesn’t faze you. It works great to vent condensation out of our bathroom. It takes a bit of an effort to manually extend it to the open position and it would be impossible for a shorter person to open it. I’m 6’, so it’s not a problem for me.



by:

Ideal for my application, no problems with operation.



by:

I’m using this fan for some supplemental ventilation over my stove in my van — the van also has a 14” square maxxair in the middle like everyone does these days.

Installation was pretty easy- I bought a compass to mark the hole and cut with a jigsaw. The provided trim is fairly forgiving, so the accuracy of your cut isn’t crucial. My roof was a bit over 2.5” thick and after trimming the fan fits pretty comfortably at that depth. I imagine a thicker roof might leave the fan a bit awkwardly recessed, though this might not be an issue.

Operation is easy and pretty much as described. The mechanism that holds the fan open doesn’t feel incredibly sturdy, but also has been ample for the job. It just doesn’t feel super “solid” when it clicks into the open position. I do find myself wishing the fan direction was reversible at times. The fan also doesn’t displace nearly as much air as the 14” square maxxair, though given the difference in area I can’t fault it for this.

All-in-all it’s been good, if not maybe a bit flimsy feeling for the price.



by:

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.


Comments
Fan was installed as per the directions. Working as described. Would purchase again. The fan only has one speed. Added a fan control switch and I can now adjust the fan speed.

Great addition on my camper van. It is mounted on our side door and we use it when cooking inside.

Was exactly what I was looking for. Was delivered very fast.


Comments
Product works even better than I expected. My friends love how easy it is to use. It looks like it was installed at the factory and totally belongs in my installation. When another needs comes up I would buy another one.

Review from a similar MaxxFan in RV Vents and Fans


I bought two and I installed them in my 2016 Promaster. I generally use one blowing in and one blowing out for circulation. I find t helps keep the condensation down inside the van at night, with myself and two dogs. The low setting is relatively quiet and sufficient at night in the Rocky
Mountains. I did a test midday to see if the van would stay cool. With all windows covered with insulated covers and both fans going it was remarkably cool inside the van after 45 minutes. Sorry no thermometer available..,

Honestly not my first time purchasing these fans. Not the best cfm on the market, but stylish, compact, and overall simple eazy use. Installation is easy with a 6inch hole saw

Review from a similar MaxxFan in RV Vents and Fans


I can't say enough about etrailer, my shipment was early, the price was very competitive and the product works great. I would caution anyone installing this fan to also use a DC to DC 12 volt converter to keep the volts to 12 volt and the amps to 5a. If you exceed this my a small amount the circuit board will burn out.....

Review from a similar MaxxFan in RV Vents and Fans


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.

The exhaust fan works as advertized and we are very happy with our purchase.

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

MA00-06200K -MaxxAir deluxe 10speed fan

I
bought this to replace the standard Fantastic Fan that was in my teardrop camper. Best upgrade ever!! The MaxxAir is SO quiet & moves the air!! The low profile smoke color lid is nice too.

Review from a similar MaxxFan in RV Vents and Fans


Great fan for the price. I used it to covert an older roof vent with no fan. It came with everything needed to install. I was nervous to cut the trim ring but it was easy and you can not see the edge once installed. I wish I would have gotten the remote since the controls set up high due to my roof design, but still easy to use. Fan is quiet to run which is a bonus.

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 researched the heck out of roof fans and selected this one. I am building a conversion camper from a cargo trailer. I have 600 hours in it and almost done. Next week is the first trip, electrical is just completed and the fan was just energized. It worked and is quiet. Best I can tell you thus far. Ask me in a yearwht i think.

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.

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

This item is an edition in the living area to aid in removing heat and add window circulation. Bathroom already had the same unit and I've used these before with great success.

Doing very well as expected. This is not my first installation as Ive installed several in trailers over the years with great results each time.

Review from a similar MaxxFan in RV Vents and Fans


1 year review- works great. Screen is easy to clean and the unit provides plenty of power. Only issue has been the squeaky fan. It squeaked/chirped from day one at low speed. Annoying but tolerable since I use it at higher speeds. Works great with no leaks during downpours.



by:

Review from a similar MaxxFan in RV Vents and Fans


Fan is... pretty good. It's quite loud, though it does move a good amount of air. The only real issue I have is the raising/lowering mechanism is a bit 'loose' and feels a bit sloppy. I'm not sure how it will hold up in the long run, but time will tell. Unfortunately, there just aren't really any competing products for this kind of smaller form factor.

  • 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".

  • Can MaxxFan Dome Roof Vent be Mounted on Side Wall
    Yes, if you'd like you would be able to mount the MaxxFan Dome roof vent on its side. I have added a photo that a customer sent in showing the same vent (in black) mounted on its side; the vent is designed to fit roofs (or walls) that are between 1" and 6" thick so as long as you have that thickness, you can mount it on the side.

    The MaxxFan Dome Roof Vent w/ 12V Fan, # MA00-03812W is a 6" diameter fan with overall length of 9-1/16". When properly installed this fan will have a vent height of 2-15/16" when closed and when open, 3-7/8". This has all mounting hardware included, but if you will need sealant too for the install. I suggest the Silicone Sealant # 0160297. And note that this also comes in black, MaxxFan Dome Roof Vent with 12V Fan # MA00-03812B.

  • 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...

  • 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 Vent...

I suggest also adding the MaxxAir Standard RV and Trailer Roof Vent Cover # MA00-933066. which will allow you to keep your vent open while keeping out rain and water. To take it a step further, you can also install the 2-Piece Polypropylene Trailer Vent for 3" Diameter Hole # WHMAV2-WAVT2 lower on the trailer to create...
