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:

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:

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



by:

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



by:

fantastic service as allways



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.



by:

Items ordered arrived on time and in perfect condition. Can't use any of them till the snow melts. All I can say is that etrailer service is fantastic.

  • 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. I've attached a video to help with some of the other components, but have attached a photo for reference to the measurement you requested.

  • 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.

  • Diameter of Output Shaft on the MaxxAir Mini Deluxe Trailer Roof Vent
    The output shaft on the fan motor within the MaxxAir Mini Deluxe Trailer Roof Vent part # MA00-03851 has a d-shape and is 1/8" diameter.

  • What is the Fan Only Amp Draw Rating of the MaxxFan Mini Plus Manual RV Roof Vent
    The MaxxFan Mini Plus Manual RV Roof Vent part # MA00-03851 draws around 2 amps max with both the fan and light on. Unfortunately, we don't have specific amp draw ratings for the fan only or the light only but the light is likely around .5 amps or less which means the fan would then take up the remainder of the amp draw rating around 1.5 amps. Please note, the fan speed on this model is not adjustable. There are three modes to choose from; fan only, light only, or fan and light.

  • Can MaxxAir Mini Deluxe Trailer Roof Vent be Powered by Wiring to Bathroom Light Switch
    The light switch in your bathroom should be connected to 12V power but I'm not sure that's where I'd connect the power for the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan # MA00-03851. Reason being that if you wanted to leave the fan on but turn the light off then you wouldn't be able to do that. Since this vent fan has it's own on/off switch I'd try to locate another 12V power source or connect this to the light circuit before the switch so that your light and fan can be operated...

  • 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.

  • MaxxAir Mini Deluxe Roof Vent # MA00-03851 The Lights Wont Turn On
    I have found in some cases when installing new vents with lights like your MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan - Powered - 1 Speed - Black Item # MA00-03851. In order for the light to work a wall switch must be turned on.

  • 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.

  • 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.

  • 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.

  • 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.

  • Are There Any 9" x 9" RV Roof Vents With Fans Available
    While there aren't any 9" x 9" options available for an RV roof vent you can easily cut the hole larger to 14" x 14" to fit a standard vent with fan. Depending on how much space you have I recommend installing the MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan - LED Light - Black # MA00-03851 or # MA00-03801 for White. These vents have a rain shield cover which will allow you to use the vent no matter the weather and even while driving, unlike other roof vents that would have to close.

  • How Many Amps Does the MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan # MA00-03801 Draw
    I spoke with my contact at MaxxAir who said that the MaxxAir Mini Deluxe Trailer Roof Vent # MA00-03801 draws just under 2 amps with the fan and the lights on. This fan is also available in black with part # 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.

    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...

  • 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.

  • Can MaxxAir Mini Deluxe Trailer Roof Vent Fit on Box Truck
    The MaxxAir Mini Deluxe Trailer Roof Vent # MA00-03851 (Black) and # MA00-03801 (White) will fit on your box truck's roof if the roof is between 1" to 4-1/2" thick and has a standard 14" x 14" opening. In regards to weight, these vents are 7 lbs. Additionally, if it is less than 1" thick would be able to use some plywood to increase the thickness to install the vent. I have added links to video reviews of both.

  • How is MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan Powered
    You will need a 12 volt power supply from a battery in order to install the MaxxAir vent you asked about, which is the following part number: - MaxxAir Mini Deluxe Trailer Roof Vent with 12V Fan # MA00-03851 This vent is a simple 2-wire design with a white ground wire and black power wire that connects to your RV's 12V power supply. It does come with the mounting screws so the only other thing you will need is sealant, the TremPro 644 Silicone Sealant # 0160297.

  • 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.

  • Can The MaxxAir Maxxfan Deluxe Be Mounted Backwards On A Trailer
    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. I got the old roof vent off and grabbed the # MA00-07500K to put up in the opening and the cover was 2" too long and came into contact with another cover on the...

  • Can The MaxxFan Deluxe Roof Vent Be Used In A Bathroom Application?
    I went ahead and checked out the MaxxFan Deluxe Roof Vent w/ 12V Fan # MA00-05301K, and it turns out that you can use this in a bathroom application, however you are going to want to make sure that you aren't putting this above any tubs, showers or range cooking surfaces and the moisture/heat would be too high for the unit. If you'd rather use a smaller roof vent fan, you also could use the MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan # MA00-03851.
