The S4D350-AN08-30 from EBM-Papst is a robust axial fan with a guard grille, designed for demanding industrial ventilation applications. The fan measures 438×438×140 mm and is powered by a three-phase AC motor (M4D074-DF) with a voltage supply of 230/400 V AC at 50/60 Hz. With an airflow of up to 3,320 m³/h and a noise level of only 56 dB(A), it delivers impressive performance while maintaining quiet operation.
The fan is ideal for ventilation systems, air handling units, and industrial refrigeration systems where high capacity and reliable operation are crucial. Thanks to the sickle-shaped blades of the HyBlade S-series, high efficiency and low noise levels are achieved in the same design.
