Roof Fan

Utilizing airflow modeling and centrifugal impeller technologies, and equipped with a dedicated direct-drive motor system, this roof ventilator—combined with an anti-corrosive cowl and a metal or FRP base—demonstrates four key core advantages:

1. High Efficiency and Energy Saving: Aerodynamically optimized impeller design significantly boosts operational efficiency.
2. Strong Corrosion Resistance: Constructed from high-quality materials to withstand various harsh environments.
3. Stable Operation: Features low vibration and low noise levels, ensuring long-term, reliable performance.
4. Easy Maintenance: Rationally designed structure substantially reduces maintenance costs.

This series of roof ventilators is divided into three main categories:

① Axial flow roof ventilators (DWT-I), with diameters ranging from Φ300-Φ2400mm, totaling seventeen sizes;

② Centrifugal roof ventilators (DWT-Ⅱ), with nine sizes ranging from Φ300-Φ1000mm;

③ Mixed flow roof ventilators (DWT-Ⅲ), with diameters ranging from Φ280-Φ800mm, totaling ten sizes. Other sizes can also be provided according to user requirements.
