The S4D300-AS34-51 from EBM Papst is a robust axial fan with a protective grille, designed for demanding ventilation applications. The fan is powered by a three-phase 400 V AC motor and delivers an airflow of up to 1,705 m³/h. With IP44 protection and ball bearings, it is suitable for continuous operation in industrial environments.
The fan is an excellent choice for units, ventilation systems, and heat recovery where high capacity and operational reliability are crucial. The three-phase motor in operating mode S1 ensures stable and uninterrupted operation around the clock.
