The S4D300-AS34-30 from EBM-Papst is a robust axial fan with a guard grille, designed for industrial ventilation systems that require high capacity and reliable operation. The fan is driven by a three-phase AC motor and delivers an airflow of up to 1,705 m³/h at 400 V AC. Thanks to HyBlade technology with sickle-shaped blades, high efficiency is combined with a low noise level of 52 dB(A).
The fan is ideal for units, cooling systems, and industrial ventilation where reliable performance and energy efficiency are crucial.
