The W4D450-CU01-02 from EBM-Papst is a robust axial fan with a wall ring for demanding industrial ventilation applications. The fan is powered by 400 V AC and comes with a three-phase motor type M4D094-EA with insulation class F. Thanks to HyBlade technology, high efficiency is combined with low noise levels and long operational reliability.
The fan is ideally suited for large ventilation units, cooling systems, and industrial processes where reliable air treatment around the clock is required. The wide temperature range down to -40 °C makes it suitable even in harsh environments.
