The 4312T from EBM-Papst is a compact DC axial fan with a flanged housing, designed for reliable and quiet cooling in demanding environments. Measuring 119 × 119 × 32 mm and offering an airflow of up to 170 m³/h, it delivers impressive performance in a small footprint. The fan is powered by a 12 V DC motor with speed control via an external NTC temperature sensor, ensuring energy-efficient and demand-responsive operation.
Thanks to its wide voltage range of 8–13.2 V and optional mounting position, the 4312T is ideal for electronics cooling, industrial equipment, and ventilation systems where compact size and stable airflow are crucial.
