The 4374S from EBM-Papst is a compact axial fan with a flanged rim for direct current, designed for reliable air circulation in demanding applications. The fan measures 119 × 119 × 32 mm and operates within a wide voltage range of 12–28 V DC, with a nominal voltage of 24 V. With an airflow of 170 m³/h and a maximum static pressure of 78 Pa, it delivers impressive performance in a small format.
The fan is ideal for electronics cabinets, industrial machinery, and medical equipment – in short, anywhere efficient cooling is required in confined spaces and flexible mounting is a necessity.

|---|---|
| Airflow at 0 Pa | 170 m³/h |
| Speed | 2800 rpm |
| Power | 5 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan has a plastic housing with dimensions of 119 × 119 × 32 mm and a weight of 0.220 kg. Mounting is done with degreased ISO 4762 M4 screws, without additional support or washer. The maximum torque during mounting is 25 Ncm at the cable outlet corner and 20 Ncm at the other corners. The mounting position for the motor shaft can be arbitrary (horizontal or vertical). |
| Casing | plastic |
| Impeller | The fan impeller is made of plastic and rotates clockwise when viewed from the rotor side. The airflow direction is outwards over the struts. With free airflow and 2800 rpm, a maximum airflow of 170 m³/h and a maximum static pressure of 78 Pa are achieved. |
| Bearing type | ball bearing |
| 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 and nominal voltage, the motor consumes 5 W and 210 mA. The motor has built-in protection against locked rotor with automatic restart, as well as reverse polarity protection via a rectifier diode. Ingress protection (IP) rating is not specified, and the motor is intended for protected indoor environments with controlled temperature and humidity. |
