Advantages

1. Excellent ventilation effect, highly suitable for air extraction or supply in ducts.
2. Strong applicability; can be used in non-corrosive, non-flammable and non-explosive gas environments.
3. Low noise: Designed with reasonable impeller angles based on aerodynamics, the fan runs without mechanical friction. Optimized blade profiles minimize noise. The noise generated is high-frequency and can be easily blocked by obstacles.
4. Stable operation: The optimized impeller minimizes axial force. High-efficiency impellers are calibrated by static and dynamic balancing, ensuring stable running with small bearing amplitude even without additional damping devices.
5. Easy maintenance: Some models are equipped with 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 air duct system during installation.
2. Cannot supply air in reverse.
3. Relatively high cost.
