  • Our take on the MaxxAir MaxxFan Plus 4500K Roof Vent Fan

    The MaxxFan Plus 4500K is a 12-inch roof vent fan for RVs that moves up to 900 CFM and runs in either exhaust or ceiling-fan mode. Its built-in rain sensor closes the lid automatically when water hits it, and the remote lets you change speed and direction without climbing up. It suits campers who want strong airflow and a vent that stays open in light rain. Against basic vent fans it adds the rain sensor, remote and reversible airflow, but it needs a 14-inch roof opening and 12V wiring, and it is louder at full speed than smaller fans.

    What reviewers say

    Owners of the MaxxFan line generally rate it highly for airflow and the rain sensor, and the Plus remote is a common reason people pick it over the base model. Complaints center on noise at top speed and on the lid closing when they would rather keep venting.

    What people mention
    • AirflowPraisedOwners say it moves a lot of air and cools a hot RV fast.
    • Rain sensorMixedIt saves interiors in sudden rain, but some find it closes too eagerly in drizzle.
    • NoiseCriticisedReviewers call it loud at the top speed setting.
    • RemotePraisedThe remote is a favorite for changing speed without reaching up.
    • InstallationMixedIt fits a standard 14-inch opening, but wiring and sealing take some work.

    Questions and answers

    Does it fit a standard RV roof opening?
    Yes. It is made for the common 14-inch square roof opening and mounts flush. Check that your opening is 14 inches and that 12V wiring reaches it.
    Can it run in the rain?
    The rain sensor closes the lid when it detects water, so it protects the interior. It does not keep venting once the lid shuts.
    What is the difference from the base MaxxFan?
    The Plus adds a remote control for speed and direction. Airflow and the rain sensor are the same idea across the line.
    Does it blow air in or out?
    Both. It exhausts air out of the RV and can reverse to act as a ceiling fan that circulates air inside.
    What power does it need?
    It is a corded 12V fan, so it wires into the RV's 12V system rather than a household outlet.
    Is it loud?
    At low and medium speeds it is modest. At the highest setting owners report it is clearly audible, which is normal for a fan moving this much air.
    Where is the MaxxAir MaxxFan Plus 4500K Roof Vent Fan cheapest?
    At Amazon, for $253.31, 30% under what the other stores charge, as of our latest check.
