The W4E350-WN02-30 from EBM-Papst is a robust axial fan with a ring wall, designed for demanding ventilation systems that require high capacity and reliable operation. The fan is powered by a single-phase AC motor at 230 V / 50 Hz and delivers an airflow of up to 2,835 m³/h. With dimensions of 557 × 417 × 179 mm, it fits well into industrial air handling units and ventilation systems.
The model is suitable for applications where continuous operation is required under varying temperature conditions, including cooled environments down to -40 °C. The guide vanes in the PP plastic casing improve aerodynamic flow and contribute to smooth and efficient operation.

| Motor frame | The fan housing is made of PP plastic and designed as a circular casing with integrated guide vanes for improved aerodynamic performance. The casing has condensate drainage holes on the rotor side. The mounting dimensions follow the standard drawing, and the fan is mounted with the shaft horizontally or with the rotor downwards as the standard position; rotor upwards can be ordered. |
| Casing | PP plastic, round, with guide vanes |
| Impeller | The fan impeller has 5 sickle-shaped (S-series) shielded sheet steel blades, press-fitted and coated with PP plastic. The rotor surface is painted black. The airflow direction is marked 'V' (away from the motor), and the fan has single-sided intake. At the maximum load point, the fan delivers 1755 m³/h against a back pressure of 70 Pa. |
| Bearing type | low-temperature grease-lubricated ball bearings |
| IP class | IP44 |
| Motor protection | thermal overload protection (TOP), internally connected |
| Motor code | M4E074-DF |
