The 6448H from EBM-Papst is a robust axial fan with a wall ring for direct current, built for applications that require high airflow and reliable operation. The fan measures 172 × 150 × 51 mm and is powered by a DC motor with a nominal voltage of 48 V and a wide voltage range of 36–56 V. With a free air flow of 460 m³/h and a maximum static pressure of 245 Pa, it delivers impressive performance in a compact format.
The fan is ideal for industrial electronics, refrigeration units, and ventilation systems where stable airflow and operational reliability are crucial. The optional mounting position makes installation easy in many different configurations.

Technical specifications
Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 460 m³/h |
| Speed | 4000 rpm |
| Power | 26 W |
| Voltage | 48 V DC VAC |
| Motor frame | The fan has a metal casing with a diameter of 172 mm, a width of 150 mm, and a depth of 51 mm. Mounting is performed via flanges on both sides using ISO 4762 M4 screws (degreased, without washers). The maximum tightening torque for the mounting screws is 260 Ncm in all corners. The shaft can be mounted in any position. |
| Casing | metal, round |
| Impeller | The fan impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. The airflow is directed outwards over the struts. At nominal operation (4000 rpm), a maximum free airflow of 460 m³/h and a maximum static pressure of 245 Pa are achieved. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor |
| Motor code | VWS0143XULCS |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 48 V and a voltage range of 36–56 V. At nominal voltage and free airflow, the power consumption is 26 W and the current consumption is 550 mA. The motor has reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. An internal fuse (4 A) is included for overload protection. |
