LED Lighting

LED Lighting

Whether you're hitting the restroom in the middle of the night, walking into the kitchen for a midnight snack, or just wanting to add a little flare to your roof vent, this LED light is the perfect night light or accent light for your RV's bathroom or kitchen. Pop it on any time with or without the fan running.


Rain Shield with Angled Louvers

Rain Shield and Louvers

Open and run your RV roof vent any time and in any weather. This one-of-a-kind rain shield fully surrounds and encloses the vent opening, so you never have to worry about pesky rainwater seeping in and damaging the interior of your RV. Its integrated angled louvers let odors, stale air, and moisture escape while allowing rainwater to run off. This solid design saves you time and money since there's no need to purchase and install a separate vent cover.


Not only does this roof vent defeat rainwater, but it protects against bugs and debris too. The vent has 2 different screens to ensure the inside of your RV is free of mosquitos and flies or remnants of leaves and loose bark from fallen tree branches. One screen is located behind the angled louvers and the other on the exterior vent opening - both remove easily for cleaning and maintenance.

Delivery was great as always. Install very easy to my ambulance/camper conversion. It was my first ceiling vent and later found I underestimated the air flow I would want in the box. Since then I have removed this to move it to the shower/bathroom where it will work best for this application. Purchased the MaxxFan Plus w/ 12V Fan, Thermostat, and Remote - Powered Lift - 10 Speed(MA00-04500K) and FanMate.

Fast shipping 1st time being a customer of E Trailer haven't hooked up item as of yet but everything looks as it should thank you ETrailer



by:

I am happy with this fan in my Ford Transit Connect. It is a standard height SWB Transit so I didn't feel I needed a more powerful fan. I like the built in light. I need this to fit in my garage so this fit the bill for a reasonable price. I will be running it off a portable power station and solar to charge the power bank. My van already had a popup vent installed so this should move some air through nicely. The installation after watching a few videos went smooth and took a few hours. I cut the roof hole, put down butyl tape and self leveling lap sealant. My roof is thinner so I did not need to use the middle extension piece. I did use my own 1" self taping screws. I would say I have moderate skills with tools and measuring. My electrical skills are minimal but I did not have any issues with this. Just put it in this morning so I haven't camped with it yet.

Great fan, used to vent air near the stove so it failed after 6 months because the motor sucked in too much grease. They warranted it out for free and the new unit is holding up much better.



by:

I love this Maxxair fan. It looks nice, clean lines, low profile and super easy to install with thorough step by step instructions.



by:

Easy to install. Has worked daily for the last year. Does not provide nearly the air flow of larger versions, but helps keep the stale air out. Excellent customer service from etrailer.



by:

This product was easy to install and does exactly what I need from it. The LED light and fan combo is perfect and I highly recommend this product. Thumbs up!!



by:

I got it installed about an hour after it was delivered. Everything I was expecting. Thank you.



by:

LED lights started flickering then went completely out after about 10 months. Good news is Maxxair made it right and sent a replacement free of charge.
It is a quiet and powerful fan. Hope the lights last in the new one.



by:

The package was delivered on time and looks great!
It was missing 2 screws but otherwise its great.
Also would be a good idea to send the required butyl tape and a small tube of caulking to make it a complete kit.

I like it a lot,I think it’s the perfect upgrade for my Chevy express van.
Will post pics,once its on.
Thank you.



by:

Disappointed in the lack of speed control and the light is very bright with on dimmer. No natural light is visible when open. Would not purchase this fan again.



by:

Great fan , the most I love about it, it's has less moving par.. example the first one that I had the top would go up and down has you use it, at a years the mechanical part broke off and I am out of $170, now with this maxx air mini fan all the moving part are from inside plus there is no hatch going up and down and the inside moving part of the maxx air are only the switches/controls.. I had replace the front of my van and now I am about to reorder another one for the back since that one broke off too and the maxx air it's seem more durable pastic... Thanks maxx air.... love



by:

Very poor quality. In less than 6 months, the control knob had fallen off. Another couple of months & the switch no longer works at all. Don’t waste your money!

This unit does have a one year warranty and I am happy to provide the details to you.

Installed new vents. No issues so far.

This vent works great as my bathroom also has a window so I really didn’t need a regular vent that opens. I couldn’t be happier with it. The LED light is a nice touch.

Good product grea service

Fans have been working good. The light on one fan stopped working recently however. I’ll probably upgrade to the bigger max fan size to move more air. I give them a 7 out of 10

  • Looking To Redo Roof On A 2010 Keystone Passport Ultralite
    Hi Christopher, There unfortunately isn't a guide to tell us the exact part numbers for the vents, skylights, etc. on your Passport. We offer a variety of plumbing vents and 12v fan vents but we unfortunately do not offer skylights. If you want to send some pictures and measurements on the plumbing vents in then we can figure out the best replacements, for the 12v fan vent I'd want your opinion on the features you'd prefer for the roof vent. The MaxxFan Mini Plus Manual RV Roof Vent...

  • Need A Replacement Dome For My Ventline Roof Vent.
    According to my research I can not find a replacement dome with the side mounted lift arm for that model anymore. You can replace it with the Ventline Ventadome Roof Vent w/ 12V Fan - Powered Lift - 14-1/4" x 14-1/4" - Smoke # V2119-603-00. I do favor the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan - Powered - 1 Speed - Black # MA00-03851. I like the style and build of the unit. plus it has a built in light. There is no need to install a separate vent cover due to the integrated...

  • RV Roof Vent Recommendation
    The smallest roof vents we carry are 14" x 14" in size. If you are willing to alter the cutout hole to fit that then I recommend the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan - Powered - 1 Speed - Black Item # MA00-03851. It has a vent cover that will allow the vent to be open in all weather and will protect against bugs and debris. It also comes with LED lights and the exhaust fan is quiet and energy efficient.

  • Replacement Bathroom Vent Recommendation for a Ventline V2290-50
    Hey Phillip, thanks for reaching out! To replace your V2290-50 the best thing we have is the Ventline Breeze LED 360 Bathroom Vent # VE76FR which is a little larger than what you have and runs off of AC power. If you're wanting to stick with 12V power then we'll have to get you a whole different vent design as the circular ones have all converted to the AC power for whatever reason. For a different design I recommend using the MaxxFan Mini Plus Manual RV Roof Vent # MA00-03851 since it's...

  • Do I Have To Reseal My Roof When Using the MaxxAir In Place Of a Fan-Tastic Vent Roof Vent
    The MaxxAir Mini Deluxe Trailer Roof Vent part # MA00-03851 will fit the same size opening as the Fan-Tastic Vent Roof Vent that you have now but you will need to use the included garnish that is supplied with the unit that way everything lines up properly. Therefore, you will need to do a bit of weatherproofing but this is really easy and all you will need is some silicone sealant like part # 0160297.

  • MaxxFan RV Roof Vent that Has Remote
    We have a similar RV roof vent that comes with a remote but the # MA00-03851 that you referenced does not come with a remote. Instead you'd want the part # MA00-07500K that does have this feature as well as a 10 speed fan instead of a single speed fan.

  • 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...

  • How Low Does the MaxxAir Mini Deluxe Trailer Roof Vent Sit Below the Ceiling
    The MaxxAir Mini Deluxe Trailer Roof Vent part # MA00-03851 once installed will sit almost flush with the ceiling. The panel which houses the light and control knob I would say is around 1/4" - 1/2" thick so that is all that would sit inside the trailer. I have attached a photo for reference.

    The only round ceiling vent we have is actually made to fit the standard vent hole that is square. It is the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan in white # MA00-03801 or black # MA00-03851. We do not carry anything that is like the residential round bathroom fan.

  • Does the Trim Piece On the MaxxAir Mini Deluxe Trailer Roof Vent Need Trimmed for Installation
    In regards to installing a roof vent like the MaxxAir Mini Deluxe Trailer Roof Vent part # MA00-03851, the white trim piece that connects the top and bottom of the vent is called the garnish and this will be trimmed to fit the exact thickness of your roof. The provided garnish works with roofs 1" to 4-1/2" thick but there are taller ones available if you needed.

  • Does the MaxxAir Mini Deluxe Trailer Roof Vent Have a High/Low Fan Speed Setting
    The MaxxAir Mini Deluxe Trailer Roof Vent part # MA00-03801 for white or part # MA00-03851 for black is a single speed fan yes. However, when the light is on the power to the fan is reduced so you will get sort of a low speed setting but it's not exactly controllable outside of this instance.

    We have the MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan, # MA00-03851 that fits roofs 1" to 4-1/2" thick with an opening size of 14" wide x 14" long. What I also like about this option is that it has a built in LED light, it is great for cargo trailer application.

  • Recommended Vent Fan for Cargo Van with Reversible Motor
    In order for a vent fan to have both an intake and exhaust feature it will need to have a reversible motor. The MaxxAir Mini Deluxe Trailer Roof Vents like part # MA00-03801 for white or part # MA00-03851 for black don't have reversible motors. Instead, I recommend the Fan-Tastic Vent Roof Vent part # FV801250. In regards to installation which will apply to pretty much all roof vents, the roof thickness will need to be at least an 1". That said, if you have a thin metal roof like in a...

  • MaxxAir MaxxFan Will Not Stop Or Close Without Pulling Fuse
    I contacted MaxxFan and according to them you have a bad circuit board. Circuit boards are model specific so you will need to purchase the correct board for your model. This means you will have to look at your fan to find the model number and identify which model you have in order to choose the correct replacement part. The Replacement Printed Circuit Board for MaxxAir Powered Lift RV Roof Vents w/ Reversible Fan # MA10A21275K is compatible with the following models: MaxxFan Plus: 00-04500K,...

  • Recommended Replacement For A Ventline AS-13M RV Roof Vent
    An AS-13M is an older Ventline model so I recommend just replacing it with a MaxxFan Mini Plus Manual RV Roof Vent # MA00-03851. This powered vent features a rain shield that will allow you to use your vent in any weather or even while driving. The LED ring light will offer extra light to see in your trailer or just offer a nice accent. I do recommend picking up some Butyl Tape # 344270341410-1 and Self Leveling Sealant # 34427034145-1 to complete your installation as the vent will only...

    Manufacturers don't list the part numbers for pretty much anything on their trailer's so we would need some more information on the vent that you have to determine which model you actually have.

  • CFM Rating for MaxxAir Mini Deluxe Trailer Roof Vent # MA00-03851

  • Exterior Height of MaxxAir Mini Deluxe Trailer Roof Vent with Fan
    The black top of the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan # MA00-03851 is just under 4 inches tall so with the white base and black top combined, it will sit about 4-1/8 inches above the roof.

    Per the manufacturer, the MaxxFan Deluxe Roof Vent w/ 12V Fan # MA00-07500K can only be placed with the louvers (back opening portion) facing the rear of the trailer. Any damage to the vent caused by it being incorrectly installed would void the manufacturer warranty. I actually ran into this a couple weeks ago doing an install.
