A roof ventilation fan is a mechanical system designed to improve airflow by expelling hot, stale air from indoor spaces through the roof. Essential components include durable fans (for air movement), motors (to power the fan), and weatherproof housing (for protection against elements). Designed with advanced technologies such as aerodynamics and thermal efficiency, these fans are built using materials like galvanized steel, often coated for corrosion resistance. Roof ventilation fans are widely used in industries like manufacturing, agriculture, and warehouses. They reduce heat buildup, enhance energy efficiency, improve indoor air quality, and maintain a comfortable, safe environment.
