Reversible, Variable-Speed Fan with Thermostat

MaxxAir Maxx Fan Plus Fan and Motor

The 12-volt, variable-speed fan has 2 modes of operation: manual and auto. When the fan is in manual mode, you can choose from 4 different speeds to increase or reduce the airflow as needed. Auto mode works in conjunction with the fan's thermostat.


To enter auto mode, press the auto mode button on either the remote control or keypad. Once the fan is in auto mode, the thermostat is activated with a set temperature of 78 degrees F. Pressing the arrow keys on either the remote or keypad changes the set temperature in 1 degree increments. When the thermostat is set, it senses the room temperature and automatically turns the fan on if it is above the set temperature. The fan shuts off when the set temperature has been reached. If the room temperature rises, the fan turns on again. This keeps your RV cool and comfortable and saves you from having to adjust the fan by hand. The auto mode also saves energy by running the fan no more than necessary, especially while you're away or asleep.


This fan is reversible, which means you are able to both exhaust stale air out of your RV and bring fresh air in from the outside. 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

MaxxAir Maxx Fan Plus Keypad

The flush-mounted keypad on the vent enables you to operate the vent and fan, including opening or closing the dome and turning the fan on or off. You can also control the fan speed, the direction of the airflow, and the set temperature for the thermostat.


Manual-Lift Dome with Twin Arms

MaxxAir Maxx Fan Plus Twin Arms

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.


MaxxAir Maxx Fan 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

MaxxAir Maxx Fan 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.


Installation

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.

Love it! Absolute must for any rv. We added two so one pulls air in and the other pushes out. No need for the air conditioner most nights. Relatively easy to install, just find power close, usually a ceiling light.

Review from a similar MaxxFan Plus in RV Vents and Fans


I love etrailer about 90% of the time. The other 10% is when I attempted to order keyed alike locks. It all ended ok but was a pain. In any case this is a review about a maxxfan 4500k. Let me just start by saying etrailers price was $125 higher than a competitors and they were willing to price match it. So a solid A+ on price matching. The box came just as it would if you bought it off the shelf. No additional packaging which is fine. I’ve had this same fan before and it works great. Thanks again for the price match etrailer. The fan will go in next week when I redo my RV roof on my Montana 3750fl.

Review from a similar MaxxFan Plus in RV Vents and Fans


So far so good. The fan arrived on time, and despite being shipped without the benefit of an outer box, there was no damage to the fan. The installation instructions were clear, and the installation was not overly complicated. The fan itself is very quiet, allows a good amount of light in, and swiftly pulls heat and presumably propane exhaust up and out of the kitchen. It’s a huge improvement for our 2011 Keystone Raptor both in terms of safety and convenience. The materials and construction of the fan appear to be of high quality, but time will tell how well it will hold up to daily use and occasional travel.

Review from a similar MaxxFan Plus in RV Vents and Fans


I ordered and installed a MaxxAir 4500K Vent fan to install in our cabover area of our Class C motorhome from Etrailer.com . This is the second one we installed, the first one in the RV bathroom is still working great after about 1 years time. Reason I installed a 2nd one is so we can have one fan exhaust air while the other fan pulls air into the RV and thereby create a wind tunnel through the RV so we can close and lock the windows but still cool the RV in moderately warm weather when we want to leave the dog in the RV and go somewhere with everything locked up. I chose Etrailer for this purchase because they had a good price and they show MaxxAir as one of their partner brands and state the fan has a 2 year manufacture warranty right on the page where it is listed. The fan was shipped quickly and I was pleased it wasn't old stock, the model label on the fan showed 2018 manufactured. I also bought a Maxx II cover for it.

Review from a similar MaxxFan Plus in RV Vents and Fans


This beats Fantastic in my opinion. Just took the motor apart to clean, that is a good thing. The features and remote are everything I could want. If you want to really clear the air 100% really works, but it can also run smoothly and very quiet at 10%. I would put a hole in my roof for this fan.


Comments
Clear the air. No problems at all. I am always amazed when the rain or wind sensor just close the cover. I did not have space to put a vent cover on. I you have the space I would recommend the additional cover. It will allow you to run the fan even if it is inclement. Cleaning is pretty easy. the screen is simple to remove but if you wish to wash the fan blades, quite possible, it is a bit more work. Keeping it clean helps and is easy. I expect my fans, yes I have two, to last as long as my RV.

Review from a similar MaxxFan Plus in RV Vents and Fans


The vent fan I ordered on line was not in stock. Etrailer advised it would take a couple weeks to get and suggested another model. I was not in rush so stayed with my original purchase. The expected delivery date continued to get pushed back. Etrailer continued to keep me advised and follow up on my order. I desired to change to the model they suggested and had it a few days later. Appreciate great customer service. It’s hard to find these days.

Review from a similar MaxxFan Plus in RV Vents and Fans


I purchased 2 MaxxAir fans about a year ago & I couldn't be more pleased with my purchase! My husband and I installed them ourselves, which was a bit of a task but still doable. Removing the old adhesive before installing the new fan was the hardest part. They aren't cheap, so I was a little hesitate before buying, but they have proven to be worth every penny! I'm actually on a cross country road trip right now, using these wonderful fans everyday since I hit the road in August. They're great for blowing out the hot air after a hot day, cooling off the rv when it gets a bit too warm inside or when you just need a little circulation. The rain sensors are so incredibly helpful and work great! The lids are a bit noisy when they open and close, but once the lid stops moving, the fan isn't that distracting at all, especially on the lower settings. I highly recommend the MaxxAir Fans!

Review from a similar MaxxFan Plus in RV Vents and Fans


Received products quickly! I did have a question regarding the wiring and called to verify since our old bathroom fan had more wiring. Within minutes it was hooked up and ready to go. They only product I would suggest to get is Butyl Tape or proper sealant before starting, saves time. We used Butyl Tape and its working great. The features on this fan are wonderful and love having a remote control. I did mount the base for it just beneath the existing switches, as the original on/off switch needs to remain on for remote to work properly. When the remote is in the holder it covers the switch. There are two features that I have experienced and love about this unit. 1) Temperature control settings and 2) Fan can be reversed bring in fresh air. We also installed the MaxxAir II RV and Trailer Roof Vent Cover - 22-3/4" x 18-1/2" x 9-3/8" - White - MA00-933072 because we like leaving the vent open at times when rv is not in use and not hooked up to electricity. This prevents weather elements from entering and also keeping birds from using it as a nesting site.

This fan is wonderful! It is working as well as the day we installed it. Highly recommend this fan!

I watch a youtube channel called "Big Truck Big RV." You sponsor this channel. This person speaks very highly of your company. I know he is compensated to, but he always gives his honest opinion. I respect his opinion and when I need to replace a faulty MAXX Air Fan, I decided to look at etrailer. The price seemed fair. It was pulled from the warehouse, shipped, and received within days. I have not opened the fan yet because I am waiting for a time when I can install it. I have confidence that if I have any issue that etrailer will help me. I am looking forward to working more with your company.

Review from a similar MaxxFan Plus in RV Vents and Fans


As an owner of 2 RV's, I discovered etrailer.com in the process of maintaining my 2006 Komfort travel trailer. I required 2 Maxxair fans. After shopping on the net, I found etrailer to have the best prices and they also had, that I couldn't find anywhere else, stainless steel braided LP gas supply line for my LP tanks. After placing the order they have stayed in touch with me about every process of my receiving them. They were packaged very well to held avoid shipment damage. These folks have shown me a great deal of respect and appreciation and I will be a loyal customer because of this. Great web site, and a good selection of products at great prices. What more could anyone expect. By the way, in my opinion, the Maxxair fans are great. I chose the 4500K.

Review from a similar MaxxFan Plus in RV Vents and Fans


I delayed writing this review until after I installed the vent fan. Having used other brands over the years, I was reluctant to change to Maxxair. Besides the cost savings, the quality of the new vent is far superior than expected. East install, quiet operation and complete without having to purchase "extras" to finish out the project. Model numbers are CLEAR and easily understood when price shopping. When my other two fans quit, (and with todays quality, they will), I'm going with the Maxxair MA00-04500K.

Still working well, even with outside temps over 110°.

looks good - not installed yet but have a couple more in already. A new minisplit ac and heat pump replaces the old rooftop rattler. Cant reach without a step stool so need remote. After 5 years have achieved heating and air conditioning heaven in my 5th whl.! etrailer is the best outfit around, their photos and videos cover the product well so you know exactly what youre paying for! The fan-tastiks are good units too but a little overpriced these days.

Product worked out wonderfully except for my shortcoming of finding the proper power supply. It was shipped immediately, arrived on time and without damage. Can't ask for much more than that. I can now use my smoke detectors and vent my kitchen area as the OEM manual vent was inaccessable and useless.

Still loving it. So glad I changed out that useless manual vent in the 9 foot ceiling.

  • Can A Maxxair Roof Vent Be added To A 2000 Starcraft Venture 1706 Pop Up Camper
    Adding a vent to your 2000 Starcraft Venture 1706 Pop Up camper requires a few things. The roof opening has to be at least 14" x 14" and the roof thickness has to be between 2" to 6-1/2" thick. If you are replacing a current vent you can remove the inside garnish to measure the opening. A few other things I recommend when installing a new fan.

  • Why Aren't Powered Roof Vent Fans Recommended Above Showers and Cooktops in RVs
    Because of the high humidity environment around showers and range cooking surfaces, it isn't recommended that a powered vent like the # MA00-04002K fan be used in those areas. The high humidity will dramatically shorten the lifespan of the circuit boards and motors of a powered fan. You can certainly install the fan, but you'll likely not be pleased by how long it would last. In that kind of environment, a manual vent like # MA00-03700 is what's recommended.

  • Replacement For Northern Breeze 12V Fan
    You are correct that the replacement motor was discontinued a number of years ago, and the motor you asked about won't work as they aren't interchangeable parts due to size, current, etc. So the only option really is a new vent, and you can choose from a standard one or go for a nice upgrade. For example basic option like the Ventline E-Z Lift Ventadome Trailer Roof Vent with 12V Fan # V3094-603-00 or something like the 4-speed MaxxFan Plus Roof Vent with 12V Fan and Thermostat # MA00-04002K.

    If the dome on your MaxxAir # MA00-04002K vent fan will not open with the manual knob then the MaxxAir # MA10-20281K-3CF "operator" is broken and should be replaced.

    The MaxxFan Dome Plus Roof Vent part # MA00-03810B is an exhaust fan so it can only pull air out.

This fan is reversible and can operate manually or by using the preset 78° thermostat. The 4000K model is still available as part # MA00-04000K, it features a 10 speed fan, versus the 4 speed offered by the # MA00-04002K. I've linked to product description videos for both vent fans

  • Will a Roof Top Vent Fit in the Opening from a A/C Unit
    Most of the roof vents that we carry will fit your opening. Unfortunately, we do not have a clear option for a roof vent cover. We have # FV803350 which will have a tinted cover that you can still see through. You could also go with the same style vent but with a white cover # MA00-04002K. We recommend pairing the roof vent with a vent cover so that you can open the vent while you are driving. Two good options would be # FVU1500BL or # MA00-955001.
