This roof fan features a molded axial-flow impeller, a built-in high-temperature motor (equipped with a dedicated motor cooling system), a rainproof cap, and a flashing base. It offers high-temperature resistance, high efficiency, compact size, and easy installation. An optional dual-speed motor enables dual-purpose operation (normal ventilation and high-temperature smoke exhaust during firefighting). Equipped with an electrical control box, it can be remotely controlled. According to the GA211-1999 firefighting fan high-temperature test method, it can operate continuously for over 100 minutes at 400°C and for 20 hours at a medium temperature of 100°C without damage. It has been approved by provincial and municipal fire departments for rooftop fire smoke exhaust and ventilation applications.
The roof fan's product structure: The conveyed gas does not come into direct contact with the motor, and it is equipped with a dedicated motor cooling system. It is heat-resistant, moisture-resistant, and corrosion-resistant, suitable for rooftop ventilation in high-temperature, high-humidity industrial environments such as the power industry, petroleum industry, chemical industry, and metallurgy.
