The A4D250-AI40-01 from EBM-Papst is a robust AC axial fan, sized at 250 mm with a round housing of 251×75 mm. The fan delivers an airflow of up to 1,030 m³/h and is suitable for demanding industrial ventilation applications. The housing is made of black-painted sheet metal, and the motor meets IP44 protection class.
The fan is excellent for use in air handling units, ventilation systems, and cooling equipment where reliable axial airflow is required. The three-phase AC motor, type M4D068-CF, can be operated in delta or star connection at 230 V and 400 V respectively, allowing flexible installation in both European and international power grids.
