Review from a similar MaxxFan in RV Vents and Fans


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

Review from a similar MaxxFan in RV Vents and Fans


I can't say enough about etrailer, my shipment was early, the price was very competitive and the product works great. I would caution anyone installing this fan to also use a DC to DC 12 volt converter to keep the volts to 12 volt and the amps to 5a. If you exceed this my a small amount the circuit board will burn out.....

Review from a similar MaxxFan in RV Vents and Fans


I purchased this maxxfan to replace the roof vent unit that came on our camper. This new vent fan is whisper quiet and best of all it can remain open while its raining. The install was easy and it fit the original hole perfectly. Used the TremPro 644 sealant also sold by etrailer and the install came out perfect. Thank You! etrailer for quick shipments and quality products.

The exhaust fan works as advertized and we are very happy with our purchase.

MA00-06200K -MaxxAir deluxe 10speed fan I bought this to replace the standard Fantastic Fan that was in my teardrop camper. Best upgrade ever!! The MaxxAir is SO quiet & moves the air!! The low profile smoke color lid is nice too.

Review from a similar MaxxFan in RV Vents and Fans


Nice product, very impressed with it’s design, construction, functions, quality and ease of operations. It looks great on my Transit van. Being it’s a medium height roof I don’t want it to be any higher than it has to be. The low profile is nice. The height of van with Maxxfan open is 9 ft. 4 in. The etrailer installation video on the Transit was very helpful. I made a frame just as described on the video. Using the 2 x 2 ft. piece of 3/4 inch plywood to make the frame is the way to go. It provides the strength I needed due to the weight of my solar panel bracket just 3 inches away. The two screws you see near the edge of the frame is the solar panel bracket. A constructed picture frame style frame would never support the weight. It is a strong solid frame. The roof is solid.


Comments
Maxxair after 1 year is working great and looking good. I didn’t. Mention in my original review that I have it powered by my solar batteries. This way there is no problem with draining the truck battery. I can leave the van locked up and windows closed and exhaust the heat for hours when away exploring.

The product was back-ordered but the communication was excellent around when the product would be back in stock And they received it and sent it out exactly when they said they would. Product was in perfect condition. Couldn't be happier with the service from etrailer.com

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.

I havent hooked it up to power yet but the install was easy once I got the hole in the van the right size. I did opt for getting different hardware. I purchased machines screws and bolts, which worked much better than the wood screws the fan came with.

Review from a similar MaxxFan in RV Vents and Fans


I love these fans. When I bought a caravan I removed the fantastic fan for one of these because it can be left open when it rains....I rarely ever closed it just so I had airflow in the caravan. Now I have a van, installed it for the same reason. Expensive, but worth it in the long run. I wish they offered a non translucent top model.


Comments
A yeah later and it still is the best thing I did to the van for increased comfort...next is solar

Review from a similar MaxxFan in RV Vents and Fans


Installed it ourselves in our 5th wheel. We have 3 Maxx Fans in our 2016 Jayco Pinnacle and all have worked flawlessly. We also had the same fans in our 2001 Jayco Designer - an earlier version - no issues. Easy to install - as long as you can safely climb up on the roof - which I have done - to make sure the seal is done correctly to prevent water from entering the coach.

Review from a similar MaxxFan in RV Vents and Fans


I am really looking forward to installing these fans, I love the concept and the design. Like everything else concerning eTrailer (and Bailey who helped me) the whole process from research, getting questions answered, the videos on the product page, the ordering, fast shipping and follow up has been awesome. I am remodeling an older motor home and everything on the roof is being replaced.. the membrane, fans, air conditioners, etc, etc.

Review from a similar MaxxFan in RV Vents and Fans


We installed this in our fifth wheel bedroom. Installation was easy in our case. It is very quiet, works well and has been reliable. A few things we've noted: 1.) We have three different models of MaxxFans in our trailer and each has an unnecessarily dissimilar interface, ex., to power off, on one unit you press the power button multiple times and on another, there is a separate power off button. Second ex. , to change fan speed, one model you press the power button multiple times, on another, there are high-low speed arrow buttons. Of course, this is only an issue because we have three different models in our trailer.; 2.) The "ceiling fan mode" where the fan reverses and sends air into the room is not particularly effective because the blade is so close to the vent cover and can't move any air. Despite those two small issues, we are very happy with our purchase and would buy again. Also note that the white vent cover BLOCKS more light than the black. We didn't realize that at purchase and there is no way to change the vent cover once installed.

Review from a similar MaxxFan in RV Vents and Fans


I use my van for construction as well as camping. I wanted an all weather fan to keep it more comfortable. I just installed the MaxxAir fan today and so far is seems great. I followed the install video for my Nissan NV2500 on etrailer.com and everything went perfectly. The only thing in did differently was use pvc board instead of plywood for the pack out material. It looks great and functions great. I would highly recommend this product.

Review from a similar MaxxFan in RV Vents and Fans


This fan works great in our camper. I like the smoke colored lid, because it helps keep the bathroom cooler. The fan is strong and pulls out all heat, moisture and odor from the bathroom. I wish we had replaced our old fan sooner, this is a much better product!

Product is well made of heavy plastics. Easy to install once you get over the fear of cutting into your vehicle. Did not hook up to power yet to see how fan operates. Looks good on roof of vehicle.


Comments
Fan was installed as per the directions. Working as described. Would purchase again. The fan only has one speed. Added a fan control switch and I can now adjust the fan speed.

The extra items you will need are as follows: Key Wall Control part # MA00A03550K Ceiling Garnish part # MA54FR RJ11 Communication Cable part # 34279523 Roof Vent Installation Kit part # 344270KITW

  • Will 14" x 14" Roof Vent Fit a 2015 Lance 1052 Camper with 14-1/4" x 14-1/4" Roof Opening
    You will definitely be able to install the MaxxAir MaxxFan Plus Roof Vent w/ 12V Fan # MA00-04751KSX on your 2015 Lance 1052 truck camper just fine. Basically anybody that measures 14" or 14-1/4" for a vent has the same vent dimensions. People will measure either the opening on the inside or outside, the lid, or even just the opening in their roof which is where the slight differences come into play. If you measured 14-1/4" then the MaxxAir vents will fit like a glove. Please note that...

  • How High does the MaxxAir MaxxFan Plus Roof Vent part # MA00-04751KSX Stick up off the Roof?
    The MaxxAir MaxxFan Plus Roof Vent part # MA00-04751KSX will be 3.25 inches over the roof line of your trailer when installed. To ensure proper installation I recommend using the Roof Vent Installation Kit part # 344270KITW. This will have all of the sealant and screws that you will need to make your vent water tight and ready for use after just a short drying period. I linked a video showing an installation.

  • Correct Replacement For A MaxxFan 4951KS
    Yes you are correct the Replacement MaxxFan Plus 4-Speed Roof Vent with White Lid # MA00-04751KSX is the right replacement and measures 18 1/8" long and 16 1/2" wide, which is the same measurements as your current MaxxFan Plus Roof Vent w/ 12V Fan, Thermostat, and Remote # MA00-04500K.

  • Is There RV Roof Vent Option with Wall Mount Controller
    I have a solution that I think would work well for you but all of the roof vents we offer for RVs do use either remotes or controllers on the assembly itself. The MaxxFan Plus Roof Vent # MA00-04500K though comes with a wall mount for the remote though so you could leave the remote in the wall mount and you'd basically have a wall mount controller. If you check out the picture I attached you can see the remote being held in the wall mount.

  • Can MaxxAir MaxxFan Plus Roof Vent # MA00-04751KSX Replace 4951KS

    If you have the wall control part # MA00A03550K installed in the wall of your trailer the Maxxair Fan part # MA00-04751KSX would easily integrate into it and work great. If you have a different switch setup let me know and I'll see what options you may have.

  • Which MaxxFan Circuit for MaxxFan with Electric Lift Arms and Rain Sensor
    Since your MaxxFan has powered lift arms and a rain sensor that would mean you have the # MA00-04751KSX and the required circuit board replacement is the part # MA39FR. At this time we do not have an install video we can share though.

    It looks like you have the MaxxAir MaxxFan Plus Roof Vent w/ 12V Fan - Powered Lift - 4 Speed - White # MA00-04751KSX. The unit sounds like it is malfunctioning and this could be due to the rain sensor # MA34FR.

If so, then simply replace that sensor. If the other features still do not work,...

  • Can RV Vent Hook up to Existing Wiring
    Vent fans are two-wire designs so they are much less complicated than air conditioning units. They only have a 12 volt wire and ground wire so you just need to be able to attach the 12 volt to a power source and have a good ground and that's all there is to it. To install them you will need the Roof Vent Installation Kit # 344270KITW and for extra wire if needed the 16-Gauge # DW02359-1, which is sold by the foot.
