Airfoil EC High-efficiency Axial Fan

1. The impeller design adopts airfoil structure, which has good aerodynamic performance and low operating noise;

2. The impeller material is made of new engineering composite materials, which is light in weight, good in strength, has good resistance to corrosion, and is suitable for various environments.

3. The airflow inlet of the square frame is designed with large rounded corners, so that the air inlet is more uniform and the efficiency of the fan is improved;

4. The size is 630-950mm, the air volume can reach 34000m3/h, and the static pressure can reach 275Pa;

5. 0~10VDC/PWM control signals or MODBUS stepless speed control.
