The 8414NH-221 from EBM-Papst is a compact DC axial fan with a flanged housing, designed for reliable cooling in electronics and industrial applications. Measuring 80 × 80 × 25 mm, the fan is powered by a 24 V DC motor with a wide voltage range of 18–28 V. With an airflow of 78 m³/h and a noise level of just 37 dB(A), it delivers efficient ventilation without unnecessary noise.
The fan is ideal for confined spaces where mounting flexibility is important—it can be mounted in any position along the motor axis. Built-in reverse polarity protection and automatic restart in case of a locked rotor make it robust and reliable.

| Motor frame | The fan features a square plastic impeller with dimensions of 80 × 80 × 25.4 mm and a mass of 95 g. Mounting is done with ISO 4762 M4 screws, and the fan can be mounted in any position along the motor shaft. The maximum tightening torque varies depending on the mounting corner: 50 Ncm at the cable exit corner and 70 Ncm at the other corners. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. The airflow exits over the struts. At a nominal speed of 3600 rpm, the fan provides a maximum free airflow of 78 m³/h and a maximum static pressure of 58 Pa. |
| Bearing type | ball bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor designed for 24 V nominal voltage with a voltage range of 18–28 V. The power consumption at free airflow is 2.4 W and the current consumption is 98 mA. The motor has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. Protection class III. |
