Variable-Speed Fan

MaxxFan Plus Fan Motor

The 12-volt, variable-speed fan operates in manual mode. You can choose from 4 different speeds to increase or reduce the airflow as needed.

This fan also exhausts stale air out of your RV. To enter ceiling fan mode, close the vent while the fan is still running. The fan then circulates the air inside your RV like a ceiling fan.

The fan has a fuse-protected, ball bearing motor that is sealed to keep out dust, dirt, and moisture.

Flush-Mounted Keypad

Keypad for MaxxFan Plus

The flush-mounted keypad on the vent enables you to operate the fan, including turning the fan on or off. You can also control the fan speed.

Manual-Lift Dome with Twin Arms

MaxxFan Plus Dual Arms - Manual

The dome on this roof vent is constructed of durable high-density polyethylene, and it is translucent so that some natural light can shine through. When it's closed, the dome provides a seamless, low-profile appearance that blends into the roof of your RV.

Unlike a dome that has only 1 arm, this manual-lift dome is supported by 2 sturdy arms so that it will not flutter during high winds or while you are driving.

MaxxFan Plus Manual Knob

And a manual hand knob is built into the underside of the vent to allow you to open and close the dome. Pull the knob outward, turn it to where you want it, and push it in to lock the dome into place.

Removable Bug Screen

MaxxFan Plus Bug Screen

This vent has a bug screen that helps keep insects and debris out of your RV. It is secured to the vent with 4 built-in retainer clips. These clips make it easy to remove the screen for cleaning or maintenance. Just rotate the clips, and the screen will pop out.


The MaxxFan Plus vent fits standard 14" x 14" openings in the roof of an RV, camper, or enclosed trailer. A white interior trim piece (or garnish), insulated electrical connectors, and hardware are included for installation. The vent also has a molded-in mounting flange that is lined with a rubber weather seal, which helps prevent leaks. Roof sealant (sold separately) is required for installation.

To install, connect the two wires on the vent to your RV's electrical system. The black wire is for power, and the white wire is for ground. Then insert the MaxxFan Plus into the opening in the roof and mount the flange to the roof. To finish, trim the garnish as needed to fit the thickness of your roof and install it.

MaxxFan Plus With FanMate Cover

For extra rain protection, install a MaxxAir FanMate vent cover (sold separately) using the molded mounting tabs located on the flange. The tabs are designed to align with the integrated brackets on the FanMate, allowing for a no-drill, tool-free installation. These tabs also have rubber inserts that prevent water from seeping in under the flange.

Video Transcript for MaxxAir RV Vents and Fans - Roof Vent - MA00A04401K Review

Today we're going to be taking a look at the MaxxAir MaxxFan. This fan is going to draw out stale, smokey or hot air from your RV. If you'd like to use this as a ceiling fan, you can close the vent lid and the motor will continue to run and circulate air within the RV cabin. It's going to feature a four-speed design. Right now I have it in the fully-open position. With this installed in the fully-open position, it's going to extend above the roof by about 12-1/4 inches.

If we move it to the fully-retracted or the fully-closed position . It's just got a manual nob right here so I'm rotating that. We're going to move it all the way to a closed position. With it in a fully-closed position, it's only going to extend above the roof by about 4-1/4 inches. I'm going to flip this over so we can see these components right here. You're going to have the manual nob.

Right here, you're going to have your on and off keypad. That's also going to be a four-speed design that's going to allow you to get the fan speed you desire. Now the fan is going to have a diameter of 12 inches and it's going to feature a 10-blade design. It does comes with the roof flange or the interior garnish or trim piece. That is included.

It's going to feature that easy-to-us keypad to control the on and off functions of the fan as well as, again, to adjust between the speeds. Now a couple of thing about the manual pull nob, which is right here. It does have a locked and unlocked position so when it's pushed in, it's locked. When you're ready to open the vent lid, you just pull that out and then it's unlocked. Then you can just rotate it clockwise or counter-clockwise to open or close the lid.

When you're done with it, whether it's open or closed, just push that back in to lock it in place. It's also going to come with an insect screen. That's right there. That's going to keep out unwanted items. That can be removed for easy cleaning. These tabs right here that just keep it in place, they rotate and then you can simply remove that. Located right here on the same point on the other side as well, we're going to have the waterproof molded mounting tabs. That's going to allow for fast and tool-free installation of a MaxxAir FanMate vent cover. That item is sold separately. The lid is smoke-colored and it has a translucent design to let through some light. Another neat thing I want to point out is right here. I need to open it back up, but I just want to point out that on the underside of the lid, it's like a dual brace design. It's got two lifting arms. What that does is that provides sturdy support for the lid when it's open. That's going to help it withstand high winds without fluttering and it can remain fully open while you're driving. That's the dual arm brace right here. It gives the unit a very strong and stable feel and overall just increases the strength, durability and stability of the unit. There is also going to be a rubber seal that goes around the opening that's going to keep dirt and moisture out. This is going to install into the standard RV roof opening, the 14 inches by 14 inches. It's designed for a maximum roof thickness of anywhere from 2 inches to 6-1/2 inches. It does comes with the necessary hardware to get it fully installed and it's going to have two wire connectors. On this unit, there's going to be a white wire and a black wire. Your white wire is going to be for ground and the black wire is going to be for power. You'll need to get that connected to a minimum 12-volt DC, 5 amp service. It comes with those butt connectors right there to easily get your wires connected. Again, it's going to come with all your mounting hardware. You're going to get the screws needed to get it fully installed. Overall, it's a really nice design. All the holes are there. They're pre-drilled. On the flange right here, they don't actually pre-drill the holes. What they do is the put divots in here so that's like a pilot start. That way, you can put the hardware in there and it just indicates where those holes are. The last thing I want to mention is the measurement we have from outside edge to outside edge. If we do that real quick, going across the front, that's going to give us a measurement of about 18-1/8 inch. Front to back, that's going to measure right around 16-1/2 inches. That's going to do it for today's look at the MaxxAir MaxxFan.

Xcellnt Vent - Installed my vent a yr ago (long story), but only made it operational 10-2018, so I Very much like that it's manual, so i could open/close it without power. Best feature, dual lift arms. Able to drive with the vent open without the lid flapping "Very Stable". A great "Basic" fan vent without all fancy stuff like Rain Sensor, Thermostat, Variable Speed, like my last one that ends up not working after parts are no longer available. 4 speeds is enough. It's Quiet. Lifetime Lid Warranty "Awesome", my last one spider cracked from UV. Only option I'd like to see is "reverse". Doesn't feel like it's moving much air with the lid closed but I have not as yet used it as a ceiling fan to circulate heat. If it does it will be the perfect vent. I will be putting it to that test in the coming months so the jury is still out on that one. 583861

Great fan for the price. Installation was easy. You will spend time removing the old dicor on the roof if you are replacing a fan like we did but it was worth it. 553408

Great still!

Nice fit, very powerful, very adjustable, and much quieter than the unit that it replaced. Appears to have an option for a winter cover, based on some additional female sliding holes of some sort? that I know nothing about. 453835

Gregory, Thank you for your review. This Maxxfan includes molded mounting tabs to install a FanMate vent cover. The FanMate part 955003 slips over the molding tabs and clips on to provide superior rain protection.

I have finally found a company that's is a pleasure to do business with. They are friendly an helpful, shipping was great and supper fast the quality was great also this will my go to for parts I need for my R V 509705

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 749504

I installed this fan in a home built camper that I filmed while building and posted the entire build on You Tube. The fan has help up perfectly and on low speed it will run a very long time with out recharging the battery. I have built five of these small campers and four of them have been equipped with this fan. 736026

Purchased to install in fifth wheel bedroom, where no fan existed, just a roof vent. Most time consuming was removing the old vent. The caulking removal was a real labor intensive operation. The factory must have used a fire hose to apply the stuff. Once the vent removed and the caulking mostly removed, the install of the maxxair went pretty smooth. Putty tape (purchased from local shop) under the rim, several stainless screws (15), came with fan, then finish roof top install with self leveling caulk around rim and on screw heads. Inside had to tie into 12v wiring at bathroom fan and fish wires to bedroom vent hole, less than 4 feet. Made connections, put on interior trim, and now wait for next RV outing to test efficiency. Works great in driveway. And one more thing, I also installed a Maxxair II vent cover in black. Helps to darken bedroom along with protecting vent. 279793

Review from a similar MaxxAir MaxxFan in RV Vents and Fans

They still work but 2 out of the 3 fans squeak at low speed.. which I feel is a little premature for only being a year old. When really they started squeaking at 6months. All in all they do a great job of exchanging the air in our rig.. 719771

Review from a similar MaxxAir MaxxFan in RV Vents and Fans

Good quality and perfect for my needs! I had one installed in the bedroom and one in the living room to replace current vents and it creates great air circulation. Haven't tested yet whether it can be open while it's raining. 680222

Review from a similar MaxxAir MaxxFan in RV Vents and Fans

We ordered and DIY-installed two of these MaxxAir fans to replace ineffective and aging vent fans in our 5th wheel RV. Installation was straightforward using the easy-to-understand instructions. All the necessary hardware is included, although you'll need some butyl tape and self-leveling sealant to complete the installation on the rooftop. We love the ease of operation, the relatively quiet 10-speed fan, and the ability to use the fan even during a rain. The mounting bracket that fits the 14" roof opening is a one-time install, meaning that you don't have to tear into the roof and sealant again should you ever need to replace the fan and cover unit with the same or similar model. I agree with all the other positive reviews I've read about this product. 680545
