The AxiBlade axial fan with EC motor is used in ventilation, refrigeration and air-conditioning systems. It transports the feed air in an axial direction parallel to the revolving motor shaft. The modular design concept includes fan housings in various sizes with an aerodynamically optimised inlet ring. Together, they are complemented by the profiled impeller geometry. The impellers have been designed for the various compatible motors, which increases efficiency and reduces running noise.
