The W4D350-CR06-31 from EBM-Papst is a robust AC axial fan with a 350 mm impeller. The fan is powered by a 4-pole AC motor, type M4D068-EC, and can operate at both 230 V and 400 V at 50/60 Hz. It is built for demanding industrial environments and delivers an airflow of 3,340 m³/h in free air.
The fan is ideal for ventilation units, industrial cooling, and air handling systems where high capacity and operational reliability are crucial. Its black-painted sheet metal casing and IP44 rating make it durable even in harsher installation environments.
