MAXXAIR503.1555 00-06200K MaxxFan Ventillation Fan with Smoke Lid and Manual Opening Keypad Control

"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.

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 Jayco 25 ft travel trailer and I left the vent open going down the road and the wind made the crank break. I could have just fixed it with an $8 replacement part but I saw this and had to have it. I liked the idea of having a built in cover so I'd never have to worry about leaving it open again, and that it has a much more useful fan over the tiny one speed fan my old unit had.The installation video on here makes the job really easy. Took me a little over 3 hours. The hardest thing is removing the old caulk which just takes time and elbow grease, just peel if off by hand, a putty knife helps. The fan works great and is very powerful. It is virtually silent on the lowest setting and will cool the unit nicely at the highest setting. It also is reversible and has a auto themostat that is set to 76 deg.One thing I did not count on, installed the controls are high up in the unit housing depending on how thick your roof is (mine is 5 inches). The crank and fan switch on the old vent were much lower in the housing and my wife could easily reach them. She now has to stand on her tippy toes to reach the controls on this one. So I advise spending the additional money to get the remote given that issue (the remote allows you to do everything and even open and close the vent without touching the fan). But otherwise very happy with it. You can tell its a very high quality unit.

This fan is a real game changer. We installed in our RV above our bed. The fan works well, in both directions, and the shroud allows it to be used in the rain. VERY nice feature! I really like the low speed controls, which use very little battery. The two lowest speeds have almost no draw, are virtually silent, and move a surprising amount of air for such low settings. Leaving here overnight is enough to keep the RV well ventilated.I also really like the ability to change fan directions. It can act to such the hot air out during the day, and at night we can reverse the flow to blow cool outside air down on us as we sleep. If you're not sure you need the fan to work in both directions, GET IT - you'll find you love it! That said, we decided we really didn't need the remote control and remote open option. Our RV is small enough that it's only a few steps to the fan to open and turn it on.Overall, I'm very happy with this fan, and would recommend it as an almost necessary upgrade for any RV.
