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.

One year later: It has worked great through the entire camping season.

Product is fine will update once installed.

etrailer yall got yo do something about your terrible shipping. I mean order on 7th of March delivered by Pony Express on the 15th. Yall got to do better. Not ordering again unless they ship thru someone other than USPS! Slowest Shipping on internet!



by:

It works nice but it does not stay latched closed. Will open every time you travel or get a strong wind.



by:

Install very easy I am going to use it to exhaust hot air when camping and I have a portable air conditioner in the van the hose will go right out the vent size 2 purposes



by:

Perfect fit on my Escape 19



by:

Perfect, shipped fast! I tried to get one locally at a large nation wide camper sales place that may or may not rhythm with Laming Sorld told me that they didn't make a fan of this model anymore! Haha! Wanted to go back and tell them to order parts from you. Thanks. Keith



by:

Easy install. Simple design. Quiet, strong fan. Looks good inside and out.

One year later this little fan is going strong venting a 3x3’ bathroom. I leave it open with the fan off for air intake sometimes too. Keeps heavy rain out when open and parked. I close it when driving in rain just in case, but have not tested it’s rain shedding ability while driving.



by:

Installation was quick and easy looks g reat



by:

Our customers love these! Thank you!



by:

Worked good



by: 04/19/2021

I run this fan with the solar for when the van is parked.

Straightforward install. Works great, moves a lot of air for its size. Wife is happy.

Still working as well as day one. Wife is still happy!



by:

I’ve ordered lots of parts for my camper from each etrailer. I’m always satisfied.



by:

I bought two of these fans to use in my bus conversion, one for the shower and one for the toilet room. Both are installed horizontally, and work well for exhausting excess vapor and bathroom odors. I am only giving them 4 stars because I have already had to reattach one of the fans to the motor shaft. I believe it was loose from shipping, but I feel like the fit of the fan and shaft could have been better.



by:

This fan is terribly noisy and is too loud to run while sleeping. Occasionally it seems to run smoothly but not before going back to making a racket. Wish it was not so noisy as the install and size are perfect for my setup.
I will be attempting to strip the insides and replace with a Computer fan wired into the switch as I want something quiet for ventilation



by:

Our '86 34' Airstream is getting all new roof components including this bathroom fan. The appeal of this kit is the included spacer so everything I need for proper inside flange alignment will be on hand when the interior skins goes back in. Excellent price, quick shipping.



by:

I bought 2 of these for a 12 by 20 off grid shed. one in shower stall and 1 above stove burners. they work great. just remember to crack a window or door so the air can be replaced. they seal closed nicely when not used. been using for about a year now.



by:

Always happy to order from etrailer. They are the first place I look for something RV or trailer related. Fast service, always in stock and excellent support



by:

It works well but fan blade started vibrating not long after installation so kinda loud, does move some serious air though



by:

Perfect for my trailer finally good ventilation and easy to install wiring.



by:

It’s not as strong of a fan as I thought it would be. Works great in the kitchen to pull out fumes.
Had to purchase a big ceiling fan to really move the air



by:

Awesome service, product, delivery time, communication. Great company, thanks etrailer.com!



by:

Compact size helps to circulate air and reduce heat in my minivan.



by:

I've had this fan for a year and use it daily to circulate the air through my van. It's simple and works fine. It would be nice if it had a reverse capability and or different speeds. But for the money, it is great.

It was scary cutting a hole in the roof to install this, but I followed the directions, and it has not leaked in several Texas and Florida thunderstorms.



by:

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.

  • Determining The Correct Replacement Round RV Roof Vent For A 2021 Nucamp T@B 400
    There isn't a guide to tell us how large the round vent is in your 2021 Nucamp T@B 400 so I'll first need you to measure the cutout hole diameter so that we can confirm a proper fitment. For example, the MaxxFan Dome Roof Vent w/ 12V Fan # MA00-03812B you were looking at requires a 6-1/4" diameter cutout hole in order to mount. This fan comes with a bug screen and rain shield so that it can be open the whole time you're setup at your campsite. You will need to pick up some butyl tape #...

  • Will MaxxFan Dome Roof Vent Work With 1971 Volkswagen Bus Van
    Hi George; the MaxxFan Dome Roof Vent w/ 12V Fan # MA00-03812B will be perfect for your 1971 VW Bus Van. It isn't overly large but still has a fan capacity of 200 CFM to get that hot air out of the bus. It also circulates air like a ceiling fan when you close the vent to help keep things cool. Vents like this one are often found on smaller Class B motorhomes which are similar in size.

  • 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...

  • What is The Appropriate Size Roof Fan For a Specified Area?
    The MaxxFan Dome Roof Vent w/ 12V Fan # MA00-03812B is capable of moving 200 cubic feet of air per minute. Assuming you have a ceiling height of 8' that would exhaust all the air in a room that is 5' wide by 5' long room every minute. Or for a room that is 8' wide(width of most rv's) and 16' long it would take just over 5 minutes to exhaust all the air(1,024 cubic feet) in that room. While there isn't a specification to how big a room needs to be for this fan it really comes down to how...

  • How To Power A MaxxAir MaxxFan Dome Roof Vent With A Wattfun Power Pack 12v Outlet
    To connect your MaxxFan Dome Roof Vent w/ 12V Fan # MA00-03812B to your Wattfun Power Pack 12v outlet you would just need some 16 gauge wire and would need to splice the wire to the fan and to a 12v male plug. To make it easy you could just cut the female end of the NOCO Extension Cable with 12V Plug - 12' Long # 329-GC019 and splice it to the fan. This would allow you to easily plug into the power pack 12v outlet and only have to make one connection with the wiring.

  • Does MaxxFan Dome Vent Move Air in Both Directions
    The MaxxFan Dome Roof Vent w/ 12V Fan # MA00-03812B does not move air in both directions. Per the manufacturer, this is an exhaust-only vent. There is not a similar option that does have a reversible fan.

  • Can MaxxFan Deluxe Roof Vent Be Installed on Mini Van
    You could technically install the MaxxFan Deluxe Roof Vent # MA00-07500K in the roof of your mini van.That being said, the main issue is going to be the mini van's roof thickness. Since the roofs on vehicles are significantly thinner than those found on RVs or trailers, the vent assembly will stick down several inches from the roof/ceiling, limiting your overhead space. A much better option to add a roof vent to your mini van would be the MaxxFan Dome Roof Vent w/ 12V Fan # MA00-03812B....

    There is not a 12 volt wire with a male end or an electrical box with a flat cover available to wire in the MaxxFan Dome Roof Vent w/ 12V Fan - 6" Diameter - Manual Lift - Black # MA00-03812B.

  • Johnson Vents Replacement Motors
    Unfortunately, we do not carry replacement parts for Johnson vents. The best we can do is replace the vent entirely. We have a small one here for your bathroom. It's the MaxxFan Dome Roof Vent w/ 12V Fan - 6" Diameter - Manual Lift - Black, part # MA00-03812B. It has a 12V fan and fits in an opening with a 6-1/4" diameter. I've linked to a video review of this one for you to look at.

  • 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. This vent is available in either white or black: - White: MaxxFan Dome Roof Vent with 12V Fan # MA00-03812W - Black: MaxxFan Dome Roof Vent with 12V Fan # MA00-03812B The...

  • Replacement Bathroom Fan for 2013 Winnebago Era 170X
    Hi Scott; we might but I don't have a way to identify what kind of fan you have in there now. I did find some review videos on the 2013 Winnebago Era 170X but none of them showed the bathroom vent, only the main 14" x 14" vent. More than likely you have a vent like the MaxxFan Dome Roof Vent # MA00-03812B which fits a 6-1/4" cutout. We also have the Ventline Breeze # VE76FR which fits a 10" cutout. If you have a different size opening or style you're looking for please let me know in...

  • Overall Height of MaxxFan Dome Roof Vent with 12VDC Fan - 6 Diameter
    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.

  • Replacement 6 Diameter MaxxFan Dome Roof Vent w/ 12V Fan
    The rain shield is not an item available separately from the MaxxFan Dome Roof Vent w/ 12V Fan - 6" Diameter - Manual Lift, # MA00-03812B. I suggest upgrading to the newer model with a 12VDC fan. The great thing about this unit is that it will draw the hot air and moisture out of your RV but even when the vent is closed, it can circulate the interior air like a ceiling fan.

  • Can The MaxxFan Dome Roof Vent w/ 12V Fan Be Used In Winter
    Because of the dome cover design the MaxxFan Dome Roof Vent w/ 12V Fan Item # MA00-03812B can be used in any weather. The integrated rain shield prevents water and debris from entering your RV so you can run it rain or shine. The bug screen keeps insects out and is easy to remove for cleaning or maintenance and the manual lift handle with push-button lets you open and close the lid with ease.

  • Solution for Needing MaxxFan Dome Roof Vent 3812b
    Hey Dick, we are not able to get that part as it looks to be a special order only item. I did find some places that offer it though and it costs more than the entire fan assembly part # MA00-03812B so at that point it might make more sense to just replace the whole thing.

  • Replacement Gasket for MaxxFan Dome Roof Vent w/ 12V Fan
    Hi Cecily; the gasket you're referring to on the MaxxFan Dome Roof Vent w/ 12V Fan # MA00-03812B must be the butyl tape. You can replace it with # AL28FJ or # 344270341410-1 depending on the width you want. You can see this in step 2 of the installation instructions for the vent.

  • Does Rear Door of Class B Motorhome Need to Be Open When Using Excel RV Tankless Water Heater
    Hello Mitzi; the rear door of your ProMaster does not need to be open when using the Excel RV Tankless Water Heater # EX93FR. Extra air flow isn't a bad idea but this has a vent-free design with an ODS (Oxygen Depletion Safety) shutoff device that detects low levels of oxygen. If you don't have good ventilation and oxygen levels drop below 18 percent, the flame extinguishes, and the fuel supply is cut off. I suppose you may find out the ventilation level isn't good enough and it shuts...
