The DWT-I Type FRP Axial Flow Roof Fan is a high-performance, corrosion-resistant ventilation unit designed for roof installation. Constructed from fiberglass composite material, it is ideal for low-pressure, high-airflow applications in industrial and commercial environments.
· The fan body is constructed from fiberglass composite material, offering excellent corrosion resistance against acids, alkalis, and corrosive chemicals.
· Compact, aerodynamic design for roof installation, with a durable, weatherproof housing.
· Optimized axial flow impeller for high airflow and efficiency, with low noise and vibration.
· Lightweight construction for easy installation and maintenance.
· Corrosion Resistance: The FRP construction provides long-term protection against corrosive gases and weather conditions, making it ideal for industrial facilities.
· High Airflow, Low Pressure: Designed for high-volume ventilation in warehouses, factories, and large commercial spaces.
· Low Noise & Energy Efficient: Optimized impeller design delivers high airflow with minimal noise and power consumption.
· Easy Installation & Maintenance: Roof-mounted design with simple access for inspection and maintenance.
The conveyed gas must not contain sticky substances. The concentration of dust and hard particles must not exceed 150mg/m³. The gas temperature must be ≤60°C, and the relative humidity can be up to 100%.
