MAXX Air Covers

Hi everybody, our new motorhome is equipped with 2 Fantastic Fans (without the rain sensors) and 1 standard bathroom fan. The manual advises against Air Covers because they will restrict air flow and increase the amount of noise. We would like to install them anyway to provide some ventilation when the coach is stored and during rains. Has anyone used Air Covers for powered fans and have they worked out for you? Appreciate any help you can provide. Thank you.

    There are 2 different types of Maxx covers. We had the Maxx air 2 installed that allows more air flow. Plus it is hinged for easy clean out.

    Have covers on all vents.The small ones on regular vents and bath room,larger on power vent.Easy to install. Do not have to worry about some one leaving a vent open when raining.

    After reading your post I looked and found three different MaxxAir covers. The standard is the smaller one and from there I see the MaxxAir 850 rain cover for high powered fans and the MaxxAir II larger vent vent cover. I'll do a little more research before I buy. Do you remember if you used one of these?

    The manual is just following the standard CYA procedures that all companies use to protect themselves.

    There are millions of RV running around out there with multiple vent covers on each one of them with no problems and many benefits.

    If you do not run the fan on high, the small ones are not going to restrict air flow. I silicone the small ones to my roof vents and after 10 years, recently replaced with smoke colored ones. Was a little surprised how much light they restricted compared to the white ones I replaced. Do not worry about the vent hitting them before all the way open as the high current from a stalled motor shuts the system off.

    I've had the MaxxAir Fan mate on mine for years without any problems. Allows me to keep the cover open 24/365. The cover does not open all the way, but I've never had any air restriction problem. That's what they're designed for.

    I really like them and would not be without them. I have 3 on my MH and 2 of them are power vents, no problem with restricted flow.

    I highly recommend vent covers, but prefer the Aero-Flo by Camco to the MaxxAir.



    MaxxAir must think they are better too, they came out with the MaxxAir II that has the benefits of the Aero-Flo. (hinged opening)
