The W2E142-BB05-28 from EBM-Papst is a compact axial fan for DC operation, designed for reliable ventilation in demanding environments. The fan delivers an airflow of up to 91 m³/h at 3,000 rpm and is powered by a 12 V DC motor with a wide voltage range of 8–15 V. The square plastic housing measures 92 × 92 × 25.4 mm and is ideal where space is limited.
The fan is well-suited for electronics cooling, industrial equipment, and ventilation systems where quiet and efficient operation is important. With a sound pressure level of only 35 dBA, it does not disturb sensitive environments.

|---|---|
| Airflow at 0 Pa | 91 m³/h |
| Speed | 3000 rpm |
| Power | 2.5 W |
| Voltage | 12 V DC VAC |
| Motor frame | The housing is square with dimensions of 92 × 92 × 25.4 mm and is made of plastic. The fan is mounted with M4 screws according to ISO 4762, degreased and without a washer. The maximum tightening torque is 40 Ncm at the cable outlet corner and 60 Ncm at the other corners. The mounting position for the motor shaft is optional. |
| Casing | plastic, square |
| Impeller | The impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. The airflow is directed outwards over the struts (air outlet over struts). In free air and at 3000 rpm, the impeller delivers a maximum flow of 91 m³/h and a maximum static pressure of 47 Pa. |
| Bearing type | ball bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 12 V and a voltage range of 8–15 V. The current consumption at free air flow is 208 mA at nominal voltage. The motor has built-in locked rotor protection with automatic restart and reverse polarity protection via a rectifier diode. The locked rotor current is approximately 640 mA at nominal voltage. |
