The 4484F from EBM-Papst is a compact axial fan with a wall ring for direct current, manufactured for demanding ventilation applications. The fan measures 119 × 119 × 25.4 mm and is powered by a DC motor with a nominal voltage of 24 V and a wide voltage range of 12–28 V. With an airflow of 168 m³/h and a sound level of only 43 dB(A), it delivers efficient and relatively quiet ventilation.
The fan is ideal for industrial electronics, cooling units, and ventilation systems where flexible mounting and reliable operation are important. Its optional mounting position makes it easy to integrate into many different designs.

|---|---|
| Airflow at 0 Pa | 168 m³/h |
| Speed | 2900 rpm |
| Power | 5.0 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan has a plastic housing with dimensions 119 × 119 × 25.4 mm and a weight of 0.165 kg. ISO 4762 M4 mounting screws, degreased and without washers, are used for fastening. The maximum tightening torque is 40 Ncm at the cable outlet corner and 10 Ncm at the other corners. The mounting position for 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 over the struts (air outlet over struts). At a nominal speed of 2,900 rpm, the fan impeller provides a maximum free airflow of 168 m³/h and a maximum static pressure of 61 Pa. |
| Bearing type | ball bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 24 V and a voltage range of 12–28 V. At nominal voltage and free airflow, the power consumption is 5.0 W and the current consumption is 210 mA. The motor has built-in reverse polarity protection via a rectifier diode and automatic restart in case of locked rotor. Protection class III applies to electrical safety. |
