Advantages

1. Excellent ventilation and air exchange effect, highly suitable for air extraction or supply in duct systems.
2. Strong applicability; can be used in non-corrosive and non-flammable/explosive gas environments.
3. Low noise: The centrifugal fan adopts a reasonable impeller blade angle design based on aerodynamics, with no mechanical friction during operation. The optimized blade profile minimizes noise. The noise generated is high-frequency and can be easily blocked by obstacles.
4. Stable operation: The optimized impeller design minimizes axial force. High-efficiency impellers are dynamically and statically balanced to ensure smooth running, resulting in small bearing amplitude without additional vibration damping devices.
5. Easy maintenance: Some models are equipped with inspection/cleaning doors, allowing maintenance and cleaning without disassembly, saving time and labor.

Disadvantages

1. Relatively large size. The air inlet and outlet directions are perpendicular, requiring proper matching with the system air ducts during installation.
2. Cannot supply air in reverse.
3. Relatively high cost.
