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.

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.



by:

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.



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



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:

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:

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:

Installed new vents. No issues so far.



by:

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:

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.



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

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



by:

It works great . Much better than the fan that came with the rv new



by:

fantastic service as allways



by:

Great fan. Wish my Tab 400 came with this from the factory.



by:

Excellent customer service! Excellent p roduct.



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 will have our customer service team reach out to you.



by:

Item arrived in good shape and looks like a quality product. Not installed yet, will add more later.



by:

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.



by:

Directions are fantastic and easy to understand. Install was a breeze.



by:

Looks and works really well really like LED light works awesome for where I put vent
Only issue I have is not with product is that it took almost two weeks to get from date I ordered it



by:

Arrived very fast. Looks just like the photo.

  • Could MaxxAir Mini and Deluxe Roof Vent Be Used in Bathroom Application
    There's no reason you couldn't use the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan # MA00-03851 as a bathroom fan. It's an exhaust fan that would do an excellent job in this application. If you'd rather use the larger in size MaxxFan Deluxe Roof Vent w/ 12V Fan # MA00-05301K you certainly could as well. The fan moves quite a bit more air and is reversible too which you might find helpful.

  • Recommended Fans for Use In Horse Trailer
    I do have an option for you but the only solar powered fan we offer is the Ultra-Fab Solar-Powered Plumbing Vent part # UF53-945001 and this would not move much air in your horse trailer. The same can be said for most solar powered fans of its kind as they are really not designed to move large quantities of air. Therefore, a much better option for you would be to install a few 12 volt powered vent fans. I recommend the MaxxAir Mini Deluxe Trailer Roof Vent part # MA00-03851 or part # MA00-03801...

  • Replacement RV Bathroom Fan Vent
    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.

  • Side Wall Mount of MaxxAir Mini Deluxe Trailer Roof Vent
    The MaxxAir Mini Deluxe Trailer Roof Vent, # MA00-03851 was not designed for side mounting. You can of course attempt to but I suggest you first consider the MaxxFan Dome Plus Roof Vent, # MA00-03810B as this product was designed for either rooftop or sidewall installation. This is designed to fit roof or walls from 1" up to 6" and is more compact than MaxxAir Mini Deluxe Trailer Roof Vent, # MA00-03851.

  • Can the MaxxFan Mini Plus Manual RV Roof Vent be Mounted on Trailer Side Wall
    The MaxxFan Mini Plus Manual RV Roof Vent part # MA00-03851 is too large and heavy to be mounted on the side wall of a trailer. Instead, I recommend using the MaxxFan Dome Plus Roof Vent part # MA00-03810B which although is not technically supposed to be mounted on the side of a trailer either, we have seen many instances of this without issue and it will be much better suited for this than the above due to the smaller size and water resistance.

  • 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.

  • Could MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan # MA00-03851 be Used in Bathroom
    The MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan # MA00-03851 can be used as a bathroom fan but not over the shower as you'll be mixing electricity and water. If you would like an exhaust vent over the shower then you would want the non-powered model # MA00-03750. I attached a review video for more info on this for you to check out as well.

  • Recommended Powered RV Vent For A 2013 Heartland Trail Runner With A 7-1/2 Thick Roof
    Technically you could use the Ventline Ventadome Trailer Roof Vent w/ 12V Fan # V2094SP-30 or the # V2094SP-28 but the garnish wouldn't be long enough to accommodate the depth of your ceiling. The largest garnish we carry for Ventline fans is # VA0445-37 at 5-5/16" so you'd have a gap between the vent and the garnish. You'd honestly be better off with the MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan - LED Light - Black # MA00-03851 or # MA00-03801 for white cover. These two vents...

  • Recommended Low-Profile RV Roof Vent For A Trailer
    The MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan # MA00-03851 or # MA00-03801 for white is going to sit the lowest to your trailer's roof at 4-1/8" in height when installed. These vents come with a Rain Shield cover which will allow you to use them no matter the weather and also while driving, unlike other models. The LED light ring gives you a convenient night light or accent light as well. I've attached a video below where I'll walk you through the installation process of these vents.

  • CFM Rating for MaxxAir Mini Deluxe Trailer Roof Vent # MA00-03851
    The CFM rating for the fan in the MaxxAir Mini Deluxe Trailer Roof Vent # MA00-03851 that you referenced is 200. 200 CFM is a decent amount that would also be on the quieter side as well.

  • Replacement Circuit Board For A MaxxFan Mini Roof Vent
    Since your MaxxFan Roof Vent, like the MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan # MA00-03851 will turn on, but won't turn off, it sounds like your circuit board. I recommend replacing your circuit board with the Replacement Printed Circuit Board for MaxxAir Powered Lift RV Roof Vents w/ Reversible Fan # MA10A21275K.

  • Replacement Bathroom Vent with 12V Fan
    I am not able to see what is currently in your 2016 Sierra 371REBH, but it sounds like you are looking for something that will function well and is made well. My recommendation is the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan - Powered - 1 Speed - White # MA00-03801 or # MA00-03851 in black that install into any 14x14 standard trailer vent opening. You can add this using installation kit # 344270KITW.

  • Roof Vent Recommendation for a 2014 Forest River Lightening Enclosed Car Hauler
    For your application I have a few options depending on what exactly you're looking to get out of a roof vent. For a basic roof vent that will just help keep heat from really building up in your car hauler trailer I recommend the MaxxAir Mini Manual RV Roof Vent # MA00-03700 because it has a manual lift and is covered so it requires no electricity and you can keep it open all the time - even when you're driving or it's raining outside. For a mid-tier option I recommend the MaxxFan Mini...

  • Difference Between MaxxAir Mini Deluxe Roof Vents # MA00-03851 and # MA00-03801
    The MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan - Black # MA00-03851 and the MaxxAir Mini Deluxe - White # MA00-03801 that you referenced are indeed identical units except for their lid color. Both are 12V DC powered exhaust fans with 1 speed option and feature an integrated rain shield to prevent water from entering the RV or trailer. Any difference in price between the two options is simply related to manufacturer pricing and supply and demand. I have attached a video demonstration...

  • Does the MaxxAir Mini Deluxe Trailer Roof Vent MA00-03851 Have A Wall Switch
    If you need a powered roof vent fan that has a control panel that you can mount on the wall then I recommend using the Ventline Ventadome Roof Vent w/12V Fan and Wall Switch part # V2119-3-533. The controls for the MaxxAir Mini Deluxe Trailer Roof Vent part # MA00-03851 are on the unit itself and there is not a wall mount for this fan so I don't think it would be a good option for what you are looking for but the above will do what you need. The Ventline Ventadome has a 12 volt fan, powered...

  • Replacement Bathroom Fan Vent for 2017 Keystone Laredo
    For a bathroom fan for your 2017 Keystone Laredo we have the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan # MA00-03851 that fits the standard 14 inch by 14 inch roof openings that RVs have for bathroom vents. This has a quiet one-speed fan and an LED light.

  • Solution for MaxxAir MaxxFan that Clicks and Fan Won't Shut Off
    Sounds like your roof vent lid isn't closing all the way when you ask it to which is why the fan isn't shutting off and also explains the clicking of the operator as it's trying to close it. In the past we've seen similar issues to this turn out to be fixed by replacing the operator with the part # MA10-20281K-1AF which is correct operator for your MaxxAir MaxxFan.

  • Recommended Vent For Cargo Trailer
    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.

  • Best RV Roof Vent For An Enclosed Trailer Used For Lawncare

The first option being the MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan - LED Light - White # MA00-03801 (black # MA00-03851). This style vent has no lift to it but does come with an LED light ring, which could be useful in your trailer when the sun goes down. This vent can fit a roof thickness of 1" to 4-1/2" thick. The next option would be the MaxxFan Deluxe Roof Vent w/ 12V Fan...

  • Replacement Motor for Ventline V2265 Vent Fan with Plug-In Port
    Since your Ventline V2265 model fan assembly features the plug-in port for the motor, the correct replacement is indeed the part # BCD0390-00. This is a direct replacement and it will plug right in just like your existing unit. Unfortunately we don't currently have a replacement fan blade that will fit your existing Ventline model. If a new blade is needed your only option will be to replace the entire unit with a current model, such as the MaxxAir Mini Deluxe # MA00-03851.

  • 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.

  • How To Wire In The MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan
    The two MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan # MA00-03851 you bought will have black and white wires hidden above the fan that you'll connect to the 12v wiring of the trailer. The black wire is your power and the white wire is your ground/neutral. To connect it to the trailer's wiring you'll need to use some butt connectors # DW05714 or wire nuts to splice the wiring together. If there isn't 12v wiring in the locations near the vents then you'll need to run some 14 gauge wire...
