Maxxfan Deluxe - All-In-One RV Vent, Shield & Fan; Built-In Rain Shield, 10 Speed Reversible Fan with Thermostat, Fits Standard 14"x14" Roof Openings, 12V Long Life Motor, White (00-05100K)

The Winnebago OEM bathroom vent fan is a pitiful waste of time. I wanted a vent I could leave open in heavy rain that would also move air. So far this Maxx Fan is functioning fine. Based on all the problems in the reviews I have no idea how long it will last. Installation is very easy for anyone with DIY skills.

I have a Keystone Passport 28 foot Travel trailer with two "standard issue" roof vents. One is over the bathroom, one is over the kitchen area. My first MAXXAIRunit that I purchased was to replace the bathroom one, because the bathroom fan seemed to be merely a noisemaker. The fan diameter was about 4" and didn't move much air.We have done RV work before, and the process to remove the old fan and vent frame and replace it with this one was no trouble. Before you start on replacing the vent with this one, make sure you have proper supplies specifically the ones needed to re-seal the replacement unit to the RV. We used Butyl rubber tape between the lip of the vent and the roof, and we used a self leveling roof sealant / caulk to additionally seal the upper part of the vent lip to the rest of the exposed roof area.Start by disconnecting any power source from the RV (shore power, batteries, etc). Removing the old vent was not an issue. We removed the outer sealant by scraping it off the frame and then removed the screws holding the vent lip to the roof. I would suggest going VERY SLOW and separating any adhesives holding the old vent in that seal it to your roof using a dull spatula like tool (Painters scraping tool that has been dulled, etc). Power was disconnected between the fan and the DC power supply (I clipped the old fan wires going into the wire nuts so that I would match the polarity of the replacement fan). Once we had the fan unit out, we cleaned the remaining sealants from the vent hole.Putting the fan base in was a relatively easy task. We sealed the area between the lip and the roof with Butyl rubber tape. We had one person inside the RV pulling the frame in place and centering it right, and the other on the roof would then screw in the frame. Most of the holes from the old frame matched the holes on the new frame so there was not a lot of worry about putting extra holes in the exterior roof.Once the frame is on and secured, we put the fan assembly on top with the vent hatch raised. Putting the 4 screws in the side of the fan (2 on passenger side, 2 on driver side) was a challenge in alignment, but after several tries, we got it in and secured.DC power connections were properly replaced (White to White, Black to Black), Inside trim frame was cut to fit (follow the directions, it's simple). and the frame was secured. The fan part now is about a full 12" (as opposed to a 4" fan) and it pulls air MUCH nicer than the old fan.We were so impressed by the fan, we bought a second to put over the Kitchen area. (and it went in quicker because if our experience on the first).Note about the Vent cover -- you DO NOT NEED an additional vent cover for this unit. The vent opens up enough where you can operate the fan and let some air out without raising it completely which helps during rain storms. Plus - we couldn't find a version of the additional vent that would actually fit over and not obstruct the operation of the vent raising and lowering.Very happy with the airflow from these vents. Got the versions without the remote control as the fan controls are very reachable by me and my wife.

Love my fan ! Works great cooling my van, would def have gotten two of them looking back

"Revised" 11/29/2024Hey, these fans are excellent!I had some issues early on but Maxxair stepped up and absolutely took care of me. Thank you Maxxair. I should have revised this 1.5 years ago.I would absolutely purchase this fan again, though the current one that Maxxair helped me with works flawelessly so I don't have a need to buy another. Super quiet, high air flow, and I run it all night in our camping trailer have experienced no negative effects, and this is on my trailer batteries for days at a time. It uses very little juice. I highly recommend. I'm sure Maxxair has removed all the ones with circuit boards that were having problems. I would buy with confidence. I only leave the information below from my original review to show where I've come from to where I am now with Maxxair. They solve problems!Read the negative reviews and believe them. I took a chance against my better judgement and purchased this fan. Just like you'll read in negative reviews and in a host of forums, for many buyers this fan runs perfectly for a while, then one day you turn it on, it runs for 10 seconds, then you get a loud obnoxious beep for about 10 seconds and it won't run. Everything I've researched says its board has very strict voltage requirements. RV's simply don't lock on to exactly 12v all day and night. Shore power, battery charge fluctuations and other factors cause a voltage variance. Everything else in my trailer runs fine with these variances, but apparently the Maxxair board was designed to operate in a vacuum with minimal voltage fluctuation. I've reached out to Maxxair but have not yet heard back. For the two days it functioned it was great. I'd recommend shopping other brands. If I get a positive solution from Maxxair I'll quickly update this review.Update 9/12/22 Still nothing from Maxxair except for the auto reply to my email 4 days ago saying someone will respond to me quickly!Update 4/25/2023. Maxxair is sending me a new circuit board. There was no explanation, just an email stating that I'll be receiving one. Hopefully this makes the fan function as it should. If it does, I'll amend this review.
