The 4312 from EBM-Papst is a compact axial fan with a wall ring for direct current, designed for reliable and quiet ventilation. The fan measures 119 × 119 × 32 mm and is powered by a brushless DC motor with a nominal voltage of 12 V. It is perfectly suited for electronic cabinets, medical equipment, and industrial devices where efficient cooling is required in a small form factor.
Thanks to its wide voltage range of 6–15 V and optional mounting position, the 4312 is easy to integrate into existing systems without complex adaptations.
