The 4394 from EBM-Papst is a DC axial fan with a wall ring, measuring 119 × 119 × 32 mm and optimized for industrial cooling and ventilation needs. It is powered by a DC motor with a wide voltage range of 12–28 V and delivers an impressive airflow of 170 m³/h at 2800 rpm. With a noise level of only 45 dB(A), it is equally suitable for sensitive environments and more demanding applications.
The fan is suitable for electronics cabinets, industrial machinery, and ventilation systems where reliable cooling and flexible voltage supply are important. The optional mounting position makes installation easy regardless of orientation.
