Large Diameter EC Fan for High-Volume Ventilation Applications
SZR's 200mm EC axial cooling fan series is designed for equipment requiring strong ventilation capacity and stable air circulation across larger cooling surfaces. By combining EC motor technology with large-diameter blade design, the fan delivers efficient airflow output while lowering operating energy consumption and acoustic load. The series is suitable for renewable energy systems, industrial ventilation equipment and large electrical cabinets.
Mechanical Configuration
The fan frame uses heavy-duty aluminum alloy construction with precision balancing treatment to maintain rotational stability at higher airflow loads.
Aerodynamic impeller blades are developed using multi-angle airflow simulation to improve static pressure distribution and air delivery efficiency.
The EC motor assembly adopts integrated electronic commutation technology to reduce electrical loss and improve operational lifespan.
Internal components are optimized for thermal resistance and reliable performance under variable environmental conditions.
