The W3G450-ZR75-01 from EBM-Papst is a powerful EC axial fan with a panel housing from the AxiEco series, designed for demanding ventilation applications. The fan combines a square PP plastic housing with an integrated guard grille and an electronically commutated motor of type M3G112-EA for three-phase operation at 400 V AC. With an airflow of up to 8,795 m³/h in free air and IP55 protection, it is excellent for harsh operating environments.
The fan is well-suited for air handling units, cooling towers, industrial ventilation, and heat recovery where high efficiency and robust construction are critical.

Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 5590 m³/h |
| Speed | 1910 rpm |
| Power | 1050W |
| Frequency | 50/60 Hz |
| Voltage | 400V AC VAC |
| Motor frame | The fan is designed as a panel fan with a PP plastic casing and integrated protective grille. Mounting is carried out via 8 holes on a relevant pitch circle, and the fan can be mounted on the flange on the intake side, via a suction nozzle, or on the flange on the exhaust side. M6 cap head screws with hexagon socket (DIN 912) are recommended for fastening. A condensate drain is located on the impeller side. |
| Casing | PP plastic, square panel housing with protective grille |
| Impeller | The impeller is made of PP plastic and has 5 blades. The rotor surface is painted black for increased corrosion resistance. The airflow direction is axial (designation V) and the direction of rotation is clockwise when viewed towards the rotor. At a nominal speed of 1910 rpm, the impeller delivers an airflow of up to 8795 m³/h in free air and a maximum back pressure of 390 Pa. |
