The 9291708111 from EBM-Papst is a compact DC axial fan with a flange, measuring 40×40×20 mm. The fan is designed for 24 V DC and is suitable for applications where space is limited but performance cannot be compromised.
Thanks to PWM control and low noise levels, it is ideal for electronics cooling, medical equipment, and industrial automation where quiet and precise air cooling is required.
- Voltage: 24 V DC (permitted range 20–28 V)
- Airflow: 14.5 m³/h at 100% PWM
- Speed: 8,100 rpm
- Maximum static pressure: 78 Pa
- Sound pressure level: 31 dB(A)
- PWM control: 21–28 kHz (typically 25 kHz)
- Built-in reverse polarity protection and automatic restart upon locked rotor
- Connection via 310 mm cable with 4 conductors

|---|---|
| Airflow at 0 Pa | 14.5 m³/h |
| Speed | 8100 rpm |
| Power | 1.45 W |
| Voltage | 24V DC VAC |
| Motor frame | The housing is square and made of plastic, with dimensions of 40×40×20 mm and a mass of 0.027 kg. ISO 4762 M4 mounting screws (degreased, without additional support or washer) are used for assembly. The maximum tightening torque during assembly is 80 Ncm at the cable corner and 90 Ncm at the other corners. The mounting position is optional relative to the motor shaft. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and is located on an axial fan with dimensions of 40×40×20 mm. The airflow is directed out over the struts. At nominal operating conditions (PWM 100%, 25 kHz), a rotational speed of 8,100 rpm, a maximum free air flow of 14.5 m³/h, and a maximum static pressure of 78 Pa are achieved. |
| Bearing type | plain bearing |
| Motor protection | automatic restart on locked rotor |
| Motor code | VWCC040YJDCS |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with electronic control via a PWM signal (21–28 kHz, typically 25 kHz). The nominal voltage is 24 V DC with an allowable voltage range of 20–28 V. The motor has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The protection class is III and the insulation resistance exceeds 10 MOhm. |
