Powerful 12-Inch Diameter: Equipped with a large **$12\text{ inch}$ ($300\text{ mm}$) fan diameter** for effective high-volume air extraction, ideal for medium to large rooms and areas requiring rapid air changes. Wall Mounted Design: Designed for permanent installation directly into a wall opening, providing efficient air removal without occupying floor or window space. Effective Ventilation: Capable of quickly removing stale air, smoke, odors, and excessive humidity, significantly improving indoor air quality. Low Noise Operation: Engineered for efficient air movement with an optimized motor and blade design to ensure **relatively quiet performance** despite its powerful output. Shutter/Backdraft Damper (Optional): Many models include an integrated **automatic louver or backdraft damper** that opens when the fan is on and closes when off, preventing unwanted air entry and insect intrusion. (Verify if your specific model has this.) Easy to Clean: The smooth PVC surfaces are simple to wipe down, maintaining hygiene and appearance in demanding environments.
