The 624N from EBM-Papst is a compact DC axial fan, complete with a wall ring and designed for reliable cooling in confined spaces. The fan measures 60 × 60 × 25 mm and operates within a wide voltage range of 12–28 V DC, offering great flexibility during installation. With an airflow of 40 m³/h and a low noise level of 35 dB(A), it is perfectly suited for applications where both performance and quiet operation are important.
The 624N is an excellent choice for cooling equipment, the telecom industry, and industrial electronics where a compact size and operational reliability are crucial.

Technical specifications
| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 40 m³/h |
| Speed | 6100 rpm |
| Power | 2.2 W |
| Voltage | 24V DC VAC |
| Motor frame | The casing is made of plastic and measures 60 × 60 × 25 mm with a mass of 0.070 kg. Mounting is performed using ISO 4762 M3 screws, degreased and without spacers or additional support. The tightening torque during assembly across both mounting flanges is max 10 Ncm at the cable outlet corner and 20 Ncm for the other corners. |
| Casing | plastic, square |
| Impeller | The impeller is made of plastic and rotates clockwise when viewed from the rotor. At a nominal speed of 6,100 rpm, the fan delivers a maximum free air flow of 40 m³/h and a maximum static pressure of 88 Pa. The impeller is designed for axial airflow where the air flows out over the struts. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 24 V and a voltage range of 12–28 V. With free airflow (∆p = 0), it consumes 2.2 W and draws 92 mA. The motor has reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. Protection class III according to electrical safety standards. |
