The MaxxFan® Black Dome is a compact ventilation solution designed for motorhome bathrooms and showers. Measuring just 6 in diameter, it fits neatly into roofs or sidewalls to provide fresh air and effective moisture control. For sidewall installations, the included fan guard doubles as a rain shield, protecting your interior from weather and debris, while also preventing accidental contact with the fan blades. All models come with a matching fan guard for sidewall applications.
