Dimension Requirements and Operational Characteristics of Axial Roof Fans

Dimension Requirements and Operational Characteristics of Axial Roof Fans Axial roof fans are a type of FRP axial fan. Aside from their FRP casing and impeller, their shape and size are identical to standard axial roof fans. Featuring corrosion resistance and acid/alkali tolerance, they are widely used in office buildings, shopping centers, theaters, seminar halls, and other venues. When the axial roof fan starts and the propeller rotates, air enters the axial impeller through the air inlet. The airflow increases along the impeller blades and flows into the guide vanes. The airflow, altered by the curvature of the guide vanes, becomes axial. The gas is then directed into the diffuser, where its kinetic energy is converted into pressure energy. The blades of axial roof fans resemble aircraft wings, which support the aircraft's weight, while corrosion-resistant blades stabilize the airflow. The cross-section of corrosion-resistant fans is typically aerodynamic, with blades fixed in position or rotating around their longitudinal axis. The blade angle relative to the airflow or the spacing between blades cannot be adjusted.
