Smoke-lid manual-lift MaxxFan roof vent with 4-speed exhaust fan, ceiling-mounted controls, 12V DC operation, and standard 14" x 14" RV roof opening fit.
The Maxxair 00B04401K MaxxFan is a standard manual-lift RV roof vent fan designed for simple, reliable ventilation. This smoke-lid model uses a high-powered 4-speed exhaust fan to help pull warm, stale, humid, or odor-filled air out of the RV while fitting the common 14" x 14" roof vent opening used on many campers, trailers, and motorhomes.
This model keeps operation straightforward with ceiling-mounted controls and a manual opening knob. It is a good option for RV owners who want a powered exhaust roof vent with a tinted smoke lid, but do not need additional automatic features such as a remote control, powered lid, rain sensor, or reversible intake airflow.
