Roof Mounted Extractor Fans are advanced ventilation solutions designed for efficient air circulation, smoke extraction, and environmental comfort across industrial, commercial, and residential spaces. Manufactured with modern aerodynamic design and durable materials, they deliver stable performance even under challenging conditions. With high airflow output, low noise levels, and energy efficiency, these fans ensure long-term, reliable operation. Shandong Wanneng Group provides these fans to meet demanding ventilation and smoke extraction requirements.
Detailed Description
Our Roof Mounted Extractor Fans are engineered to combine durability, high performance, and energy efficiency. Equipped with multi-wing forward-curved impellers, these fans produce powerful airflow with minimal noise, ensuring a comfortable environment for users. They are capable of running continuously at high temperatures up to 300°C for more than 60 minutes, making them a dependable choice for fire safety and industrial ventilation applications.
If a single unit cannot meet specific air volume requirements, multiple fans can be installed in parallel, providing scalable solutions for large facilities. The robust construction and advanced aerodynamic design guarantee stability, efficiency, and long service life. Ideal for factories, warehouses, shopping centers, and large buildings, these extractor fans ensure fresh, clean, and safe air circulation while reducing operational costs through energy-saving technology.

Installation Precautions
To maximize performance and extend service life, follow these guidelines during installation:
-
Foundation Requirements: The fan base must be higher than the roof surface, perfectly level, and fitted with anchor bolts to avoid water leakage and ensure stability.
-
Vibration Control: Place a 5mm rubber pad under the base and use spring washers on anchor bolts to reduce vibration and prevent loosening.
-
Outlet Standards: Never reduce the outlet diameter; larger outlets are acceptable. Install an insect-proof net and wind cap if exposed to strong winds.
-
Winter Usage: In cold regions, operate fans regularly to prevent snow or ice from blocking the outlet.
-
Duct Connection: Use flexible, flame-retardant hoses (minimum 200mm) that match inlet/outlet sizes. Ensure moderate tension—tight enough to prevent sagging but not so tight as to distort airflow.
