Advantages

1. Excellent ventilation and air exchange performance, ideal for air extraction or supply in duct systems.
2. Wide applicability; suitable for non-corrosive, non-flammable and non-explosive gas environments.
3. Low noise: Designed with rational impeller blade angles based on aerodynamics, the fan operates without mechanical friction. Optimized blade profiles minimize noise. The noise produced is high-frequency and can be easily blocked by obstacles.
4. Stable operation: The optimized impeller design minimizes axial force. High-efficiency impellers are calibrated through static and dynamic balancing, ensuring smooth running with small bearing vibration 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 intake and air supply directions are perpendicular, requiring proper matching with the system air ducts during installation.
2. Cannot supply air in reverse.
3. Relatively high cost.
