The 6318N/2H3PU from EBM-Papst is a powerful DC axial fan with a wall ring, built for demanding industrial environments. The fan measures 172×172×51 mm and operates within a voltage range of 36–60 V DC, with a nominal voltage of 48 V. With a free air flow of up to 680 m³/h and a maximum static pressure of 450 Pa, it delivers impressive performance in a compact format.
Thanks to its IP68 rating and metal housing, the 6318N/2H3PU is ideal for applications with high demands on sealing and operational reliability – for example, industrial equipment, cooling systems, and heavy-duty ventilation solutions.

Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 680 m³/h |
| Speed | 5000 rpm |
| Power | 58W |
| Voltage | 48 V DC VAC |
| Motor frame | The fan has a metal casing with a depth of 51 mm and a diameter of 172 mm. Mounting is done via a flange with ISO 4762 M4 screws, degreased and without additional support or washer. The maximum permissible torque during mounting is 600 Ncm in all corners. The mounting position for the axis is arbitrary. |
| Casing | metal, axial fan 172 mm diameter |
| Impeller | The fan impeller is made of plastic and is mounted on an axial fan with a diameter of 172 mm. The airflow direction is air outlet over struts. At a maximum speed of 5000 rpm, a free air flow of 680 m³/h and a maximum static pressure of 450 Pa are achieved. The optimal operating point is 490 m³/h at 200 Pa. |
| Bearing type | ball bearing |
| IP class | IP68 |
| Motor protection | automatic restart on locked rotor |
| Motor code | 6318N/2H3PU |
| Rotation direction | counter-clockwise (viewed from the rotor) |
| Motor type | The motor is an electronically speed-controlled DC motor with a nominal voltage of 48 V and a voltage range of 36–60 V. Power consumption at free airflow is 58 W at nominal voltage. The motor has built-in reverse polarity protection via a rectifier diode and automatic restart in case of locked rotor. An internal fuse (Littelfuse Nano2, 4A/75V) protects the circuit, and the motor has a start-up delay of 2.2 seconds after the supply voltage is applied. |
