The 624HH from EBM-Papst is a compact axial fan with a wall ring for direct current, measuring 60 × 60 × 25 mm. It is designed for 24 V DC with an operating voltage range of 18–28 V and is excellent as a spare part or component in new designs. The fan delivers an airflow of 56 m³/h and is a reliable choice for cooling in confined spaces.
The fan is well suited for cooling electronics, control cabinets, and industrial equipment where a compact form factor and stable air performance are required.

|---|---|
| Airflow at 0 Pa | 56 m³/h |
| Speed | 8,200 rpm |
| Power | 2.9 W |
| Voltage | 24V DC VAC |
| Motor frame | The casing is made of plastic and has dimensions of 60 × 60 × 25 mm with a weight of 70 g. ISO 4762 M3 mounting screws are used for assembly, and the torque limit varies depending on the corner: 10 Ncm at the cable outlet corner and 20 Ncm for the other corners. The mounting position for the shaft is optional. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and designed for axial flow where the air is directed out over the support arms. At a nominal speed of 8,200 rpm, a maximum airflow of 56 m³/h is achieved at free airflow and a maximum static pressure of 145 Pa. The optimal operating point is 40 m³/h at 51 Pa. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor without a specified motor designation, designed for a nominal voltage of 24 V DC with a voltage range of 18–28 V. The motor has built-in protection against locked rotor with automatic restart, and reverse polarity protection via a rectifier diode. The motor shaft can be mounted horizontally and the direction of rotation, when viewed facing the rotor, is clockwise. |
