The A4D350-AN08-01 from EBM Papst is a powerful axial fan in HyBlade design, engineered for demanding ventilation applications. With a compact size of 352×352×110 mm and a three-phase AC motor, it delivers impressive performance with an airflow of up to 2,105 m³/h. The fan is ideal for air handling units, heat recovery, and industrial ventilation where high capacity and operational reliability are crucial.
Thanks to HyBlade technology – a hybrid construction with sickle-shaped blades made of pressed steel sheet injected with PP plastic – high efficiency is combined with a low noise level of just 56 dB(A). The M4D074-DF motor can be connected in both star and delta configurations for 400 V and 230 V respectively, providing great flexibility during installation.
- Airflow: 2,105 m³/h
