The 624H from EBM-Papst is a compact axial fan with a wall ring for DC current, in the format 60 × 60 × 25 mm. The fan is designed for 24 V DC with a wide voltage range of 18–28 V, making it flexible in many applications. It is ideal for electronics cabinets, cooling units, and industrial equipment where space is limited.
Thanks to ball bearings and automatic restart in case of locked rotor, the 624H is built for long operating life and high reliability. The built-in reverse polarity protection provides extra safety during installation.

Technical specifications
| Product attribute | Value |
|---|---|
| Speed | 6850 rpm |
| Power | 1.9 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan has a square plastic casing measuring 60 × 60 × 25 mm and a mass of 0.070 kg. Mounting is done via flanges with ISO 4762 M3 screws (degreased, without washer or extra support). The maximum tightening torque is 10 Ncm at the cable outlet corner and 20 Ncm at the other corners. The motor shaft can be mounted in any position. |
| Casing | plastic, square |
| Impeller | The impeller is made of plastic and designed for axial airflow with the air discharge over the support struts. At a nominal speed of 6,850 rpm, the impeller delivers a maximum free air flow of 46 m³/h and a maximum static pressure of 105 Pa. The optimal operating point is 34 m³/h at 36 Pa. The impeller rotates clockwise when viewed from the rotor side. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor |
| Motor code | VWCD060AJEFS |
| Rotation direction | clockwise (viewed facing the rotor) |
| Motor type | The motor is a DC motor with a nominal voltage of 24 V and a voltage range of 18–28 V. The power consumption at free airflow is 1.9 W and the current consumption is 80 mA at nominal voltage. The motor has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The motor casing is made of plastic, and the motor is classified as protection class III. |
