High Pressure Roof Mounted Centrifugal Fan
,Corrosion Resistant Centrifugal Roof Fan
DWT-II Type FRP Centrifugal Roof Fan
The DWT-II Type FRP Centrifugal Roof Fan is a high-pressure, corrosion-resistant ventilation unit designed for roof installation. Constructed entirely from fiberglass composite material, it is ideal for applications requiring higher static pressure, such as industrial facilities, warehouses, and commercial buildings.
DWT-II Model Features
Material & Structural Properties
· The base, impeller, and wind cap are all constructed from high-quality fiberglass composite material, offering excellent corrosion resistance against acids, alkalis, and corrosive chemicals.
· Centrifugal design delivers higher static pressure compared to axial roof fans, making it suitable for systems requiring more pressure.
· Compact, aerodynamic design with a durable, weatherproof housing.
· Optimized impeller for high efficiency, low noise, and reliable operation.
Core Advantages
· High Static Pressure: Centrifugal design provides significantly higher pressure than standard axial roof fans, making it ideal for long duct runs or high-resistance systems.
· Full FRP Construction: Corrosion-resistant fiberglass composite material ensures long-term performance in corrosive and outdoor environments.
· 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.
