The 8418N/2H from EBM-Papst is a compact DC axial fan in the 80 × 80 × 25.4 mm form factor, designed for demanding cooling and ventilation applications with a 48 V DC supply. The fan delivers up to 78 m³/h at free air flow and a maximum static pressure of 60 Pa. With ball bearings and a calculated service life (L10) of 70,000 hours at 40 °C, it is built for long-term operation.
Thanks to PWM speed control and a built-in tacho signal (open collector), the 8418N/2H is ideal for applications requiring precise speed control and monitoring – for example, in server cabinets, industrial electronics, and medical equipment.

|---|---|
| Airflow at 0 Pa | 78 m³/h |
| Speed | 3700 rpm |
| Power | 3.4 W |
| Voltage | 48 V DC VAC |
| Motor frame | The fan is mounted via the flanges in all four corners using ISO 4762 M4 screws, degreased and without a washer. The maximum tightening torque varies depending on the corner: 50 Ncm in the cable outlet corner and 70 Ncm in the other corners. The mounting position for the shaft is optional. The housing is made of plastic and the fan weighs 0.095 kg. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and mounted on an axial fan with dimensions 80 × 80 × 25.4 mm. The airflow direction is outlet over struts and the direction of rotation is counter-clockwise when viewed towards the rotor. At free airflow and a nominal speed of 3,700 rpm, a maximum airflow of 78 m³/h and a maximum static pressure of 60 Pa are achieved. |
| Bearing type | ball bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is an electronically controlled DC motor with PWM speed control in the voltage range 35–60 V DC with a nominal voltage of 48 V. It is equipped with reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The motor has a built-in tachometer signal of type /2 (open collector) for speed measurement. The service life (L10) is 70,000 hours at 40 °C ambient temperature. |
