The 6424M from EBM-Papst is a robust DC axial fan with a wall ring, designed for demanding ventilation applications. The fan measures 172 x 150 x 51 mm and is powered by a DC motor with a wide voltage range of 12–32 V. With a generous airflow of 325 m³/h and a low noise level of 49 dB(A), it is well-suited for industrial climate and ventilation systems.
Thanks to its optional mounting position and metal housing, the 6424M is easy to integrate into existing designs. It is ideal for control cabinets, industrial equipment, and air handling units where reliable and consistent air circulation is required.
