The 8414NHU from EBM-Papst is a compact DC axial fan with a flange, in a format of 80 × 80 × 25 mm. It is built for demanding environments thanks to its IP68 protection rating and ball bearings with an impressive L10 lifetime of 70,000 hours at 40 °C. The fan is perfectly suited for applications where operational reliability and long service life are crucial.
With a wide voltage range of 18–26 V DC, the 8414NHU is easy to integrate into industrial and automation systems, medical equipment, or outdoor installations where moisture and dust place high demands on sealing.

|---|---|
| Airflow at 0 Pa | 78 m³/h |
| Speed | 3600 rpm |
| Power | 2.4 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan has a square plastic casing with dimensions of 80 × 80 × 25.4 mm and a mass of 0.095 kg. Mounting is done with ISO 4762 M4 screws, degreased and without washers. The maximum permissible torque during mounting varies depending on the corner: 50 Ncm at the cable outlet corner and 70 Ncm at the other corners. The mounting position on the shaft is optional. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. The airflow is directed with the air exhaust over the struts. At a nominal speed of 3,600 rpm, a maximum free airflow of 78 m³/h and a maximum static pressure of 58 Pa are achieved. The optimal operating point is 64 m³/h at 14 Pa. |
| Bearing type | ball bearing |
| IP class | IP68 |
| Rotation direction | counterclockwise (viewed from the rotor side) |
| Motor type | The motor is a DC motor with a nominal voltage of 24 V and a voltage range of 18–26 V. The power consumption at free air flow is 2.4 W and the rated current is 100 mA. The motor has built-in restart protection for locked rotor conditions and reverse polarity protection via a rectifier diode. The bearings are ball bearings with an L10 lifetime of 70,000 hours at 40 °C. |
