The 4312NHH is a DC axial fan from EBM-Papst in the S-Panther series. The fan measures 119 x 119 x 32 mm and delivers an impressive airflow of 250 m³/h at 3600 rpm. It is powered by a DC motor with a nominal voltage of 12 V and a wide voltage range of 6.0–13.2 V.
The fan is ideal for cooling units, electronics cabinets, and industrial equipment where a compact size and high performance are required. Optional mounting position and motor shaft make it easy to integrate into existing designs.
