The W1G250-HJ20-02 from EBM-Papst is a powerful DC axial fan with a wall ring, measuring 280×280×84 mm and powered by an electronically commutated EC motor at 48 V DC. It combines high performance with robust construction and is well-suited for demanding industrial ventilation applications. The IP6K9K protection class for the electronics makes it resistant to high-pressure washing.
The fan is perfectly suited for applications where operational reliability, energy efficiency, and resistance to moisture and dust are crucial – for example, in the food and process industries.

|---|---|
| Airflow at 0 Pa | 1300 m³/h |
| Speed | 3000 rpm |
| Power | 121 W |
| Voltage | 48 V DC VAC |
| Motor frame | The casing is made of cast aluminium and is painted black. Mounting is done with self-tapping M5 and M6 screws respectively, according to the product drawing. Condensate drainage holes are located on the rotor side. The mounting position is with the shaft horizontal or the rotor downwards; mounting with the rotor upwards is possible upon request. |
| Casing | cast aluminum, black lacquered |
| Impeller | The impeller is made of PP plastic and has 7 blades. The airflow direction is marked V (exhaust from the rotor side). The direction of rotation is counter-clockwise when viewed from the rotor. Under nominal operating conditions, the impeller delivers up to 1300 m³/h at a static pressure drop of 130 Pa and a speed of 2625 rpm at the optimal efficiency point. |
| Bearing type | sealed bearings |
| IP class | Motor IP24KM, electronics IP6K9K |
| Motor protection | thermal overload protection for electronics |
| Motor code | M1G074-BF |
| Rotation direction | counter-clockwise, looking at the rotor |
| Motor type | The motor is an EC type (electronically commutated) with the designation M1G074-BF and operates on 48 V DC with a nominal voltage range of 36–57 V DC. The rated power is 121 W at a rated current of 2.5 A and a nominal speed of 3000 rpm. The motor is equipped with sealed ball bearings and insulation class B. The ingress protection rating for the motor is IP24KM and for the electronics IP6K9K (with connected counter-connector). The motor has several protection functions such as current limiting, soft start, overvoltage detection, thermal overload protection for the electronics, and reverse polarity protection. |
