The 5212NH from EBM-Papst is a compact DC axial fan with a wall ring, designed for reliable and efficient air circulation. The fan measures 127 × 127 × 38 mm and is powered by a DC motor with a nominal voltage of 12 V and a wide voltage range of 7–14 V. It is ideally suited for electronics cooling, industrial equipment, and ventilation systems where stable airflow is crucial.
Thanks to its ball bearings and robust plastic casing, the 5212NH can withstand demanding operating environments with a long service life. The motor's built-in protection against reverse polarity and automatic restart in case of a locked rotor makes it a reliable choice for OEM manufacturers and service engineers.
