The W4E300-CS72-30 from EBM Papst is a robust axial fan with a wall ring, built for demanding ventilation applications. The fan measures 397×397×88 mm and is powered by a single-phase AC motor at 230 V and 50/60 Hz. Thanks to HyBlade technology with sickle-shaped blades, high airflow is combined with low noise levels.
The fan is ideally suited for air handling units, heat recovery, and industrial ventilation where reliable operation and energy efficiency are crucial. The optional mounting position provides great flexibility during installation.
