The 624L from EBM-Papst is a compact DC axial fan with a wall ring, in the 60 × 60 × 25 mm format. It is ideal for densely packed electronic devices and control systems where quiet and reliable cooling is required. With a voltage range of 18–28 V DC and a nominal voltage of 24 V DC, it is easy to integrate into most DC systems.
The fan is aimed at manufacturers and service technicians in industry, automation, and medical equipment – applications where low noise levels and long operating times are crucial.

Technical specifications
| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 21 m³/h |
| Speed | 3200 rpm |
| Power | 1 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan has a square plastic housing with dimensions of 60 × 60 × 25 mm and a mass of 0.07 kg. Mounting is done with M3 screws (ISO 4762) without a spacer. The maximum tightening torque for mounting is 10 Ncm in the cable corner and 20 Ncm in the other corners. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and generates an axial airflow with air discharge over the struts. At a nominal speed of 3,200 rpm, the fan impeller provides a maximum free airflow of 21 m³/h and a maximum static pressure of 28 Pa. The sound pressure level at free airflow is 20 dB(A) measured at a distance of 1 meter. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with no specified electrical functions but with reverse polarity protection via a rectifier diode. The locked rotor protection has automatic restart. The voltage range is 18–28 V DC with a nominal voltage of 24 V DC. The current consumption at free airflow is 42 mA at nominal voltage. |
