This past weekend we picked up the MaxxAir fan, simple 4 seed manual open,to replace the stock single speed fan in our Avenger travel trailer bathroom. With the vent cover over it that little fan barely pulled the steam from the shower out of the room much less drew any air through the trailer. Anyway, Removal was as I expected except, when I lifted the fan from the roof,there was no Butyl tape. It had the same caulk that was on the top side covering the screws and flange. I don't guess it is anything "wrong" with it,but of all the videos and how to's I had read they all had butyl tape under the factory install. It did make for a longer prep for the new install. Is this another example of Prime Time cutting corners? I've found a few...Now I just have to adapt my perfectly good Camco cover to the new fan. MaxxAir fans are now made to only use redesigned MaxxAir covers.

Guy'sI just installed the same fan in the living area of my RV a few weeks ago, prior to a visit to the North Rim, and it seemed to work well enough to keep air moving in that larger area. I did use the Maxxair cover on mine which is supposed to allow additional air flow. I am surprised to hear you had such poor performance. Could you possibly have a reduced voltage at the fan due to poor connections? Just surprising to me since mine works so well.

I think he is talking about the little whirr and buzz being inadequate, not the new one.a reminder, do not have the bathroom door closed, the fan on max and flush the toilet.bumpy

Yes,I'm talking about the old fan being very weak. The MAxxAir fan preformed great. With both doors open I could got each one and feel air being drawn in.
I was was just surprised that Prime Time used Lap Sealant under the old fan flange as I have never seen or read of it before. That was mainly what my post was about.

Speaking of MaxxAir. I would like to find a MaxxFan 1200T.
I put one on our 2003 mh. In 2015 we bought a new mh, and when I tried to get another 1200T, I found that that model is no longer made. We liked that model so well that we want another.

If you had the same caulk under the fan that you had over the fan the manufacturer did an excellent installation job and you should have no concerns. This is fairly normal and very good installation using a Dicor type caulk under mounts.

You're lucky. A lot of the sealants cure to be almost unremoveable, making it near impossible to remove whatever without damaging the roof. Good quality butyl tape (Dicor makes that, too) under, sealant on top. That way you can carefully cut through the sealant around the edges and easily remove whatever since the butyl won't act like a strong adhesive. That applies double for things with wide flanges, like the base for an antenna.
