The 4624N from EBM-Papst is a robust axial fan with a wall ring, designed for demanding industrial ventilation applications. The fan measures 119 × 119 × 38 mm and is powered by a 24 V AC motor supporting both 50 and 60 Hz. It is a twin-compatible model with a metal housing and a balanced impeller for long and stable operation.
The fan is ideal for air handling units, cooling systems, and industrial ventilation where reliability and flexible mounting are important. Optional mounting position and plug connection make installation easy.
