The 8315100157 from EBM-Papst is a powerful DC axial fan, designed for demanding industrial applications where high airflow and a compact design are crucial. Measuring 172 × 150 × 51 mm, the fan is powered by an electronically speed-controlled 24 V DC motor designated AF172-00157. With a maximum airflow of 530 m³/h and a static pressure of up to 660 Pa, it delivers impressive performance in a robust metal housing.
The fan is ideal for applications requiring reliable cooling or ventilation – for example, in industry, power electronics, and telecommunications. The optional mounting position makes installation flexible.

|---|---|
| Airflow at 0 Pa | 530 m³/h |
| Speed | 6800 rpm |
| Power | 58W |
| Voltage | 24V DC VAC |
| Motor frame | The casing is made of metal with an outer diameter of 172 mm, a width of 150 mm, and a depth of 51 mm. ISO 4762 M4 screws are used for mounting, and the maximum tightening torque for mounting is 190 Ncm in all corners. The fan weighs 0.86 kg and can be mounted in any position with respect to the shaft orientation. |
| Casing | metal |
| Impeller | The fan impeller is made of plastic and is mounted in an axial fan with the airflow direction outward over the support struts. At 6,800 rpm and free air flow, a maximum flow of 530 m³/h and a maximum static pressure of 660 Pa are achieved. The optimal operating point is 425 m³/h at 255 Pa. The fan impeller rotates counter-clockwise when viewed toward the rotor. |
| Bearing type | ball bearing |
| Motor protection | locked rotor protection with automatic restart |
| Motor code | AF172-00157 |
| Rotation direction | counter-clockwise (viewed from the rotor) |
| Motor type | The motor is an electronically speed-controlled DC motor with a nominal voltage of 24 V DC and a voltage range of 16–30 V DC. Power consumption is a maximum of 58 W with free airflow and 100% PWM. The motor has built-in reverse polarity protection via a rectifier diode and locked rotor protection with automatic restart. An internal Littelfuse NANO2 6.3 A/125 V fuse is installed, and the motor also has built-in under- and overvoltage protection. |
