The W3G500-KM03-M1 from EBM-Papst is a powerful EC axial fan with a wall ring, designed for demanding ventilation applications where high capacity and energy efficiency are crucial. The fan delivers an impressive 5,735 m³/h at 1,370 rpm and is powered by an electronically commutated EC motor for three-phase operation. With an IP55 protection rating and robust construction, it is perfectly suited for industrial environments with high demands on reliability.
Thanks to the integrated PID controller, soft start, and RS-485 MODBUS-RTU communication, the fan is easy to integrate into modern control systems. It is a natural choice for large ventilation units, cooling systems, and air handling units.

Technical specifications
Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 5735 m³/h |
| Speed | 1370 rpm |
| Power | 630 W |
| Frequency | 50/60 Hz |
| Voltage | 400V AC VAC |
| Motor frame | The fan casing is made of PP plastic, and the protective grille is steel coated with black plastic (RAL 9005). The guide vanes are also made of PP plastic. The installation position is either with a horizontal axis (the support struts are mounted only in the X-position) or with the rotor downwards; in the horizontal axis position, the cable outlet must be placed on the lower right. Condensate drainage holes are located on the rotor side. |
| Casing | PP plastic, round; electronics housing in cast aluminum, black lacquered |
| Impeller | The fan wheel has 5 shielded blades with a scythe-shaped (S-series) profile for high efficiency and low sound pressure. The blades are made of pressed sheet metal (bright steel) and coated with PP plastic by spraying. The airflow direction is marked V and the direction of rotation is counter-clockwise when viewed towards the rotor. At nominal operation (1370 rpm, 400 V, 50 Hz), the fan delivers up to 5735 m³/h with a maximum static pressure increase of 170 Pa. |
| Bearing type | low-temperature grease ball bearings |
| IP class | IP55 |
| Motor protection | Thermal overload protection (TOP), internally connected |
| Motor code | M3G084-GF |
| Rotation direction | counter-clockwise, looking at the rotor |
| Motor type | The motor is an EC motor (electronically commutated) of type M3G084-GF for three-phase operation (3~) with a rated voltage of 400 V AC (range 380–480 V AC). It has insulation class F and operating mode S1, which means continuous operation. The motor is equipped with an integrated PID controller, soft start, motor current limitation, and RS-485 MODBUS-RTU communication. Thermal overload protection (TOP) is internally wired and protects both the electronics and the motor. |
