The 7112N/2 from EBM-Papst is a compact DC tube axial fan, designed for efficient and quiet cooling in a wide range of applications. Measuring 92 × 92 × 25.4 mm, the fan is powered by a 12 V DC motor with a voltage range of 8–15 V. With an airflow of 91 m³/h and a low sound pressure of 35 dB(A), it combines performance with discreet operation.
The fan is ideal for electronics cabinets, server equipment, and industrial control systems where reliable cooling is required in confined spaces. Its optional mounting position and flexible connection cable facilitate installation in most designs.

|---|---|
| Airflow at 0 Pa | 91 m³/h |
| Speed | 3000 rpm |
| Power | 2.5 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan is mounted via mounting flanges with ISO 4762 M4 screws, degreased and without washers. The mounting position for the shaft is optional. The maximum tightening torque during assembly is 40 Ncm in the cable outlet corner and 60 Ncm in the other corners. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and is housed in a plastic casing with dimensions of 92 × 92 × 25.4 mm. At 3000 rpm and free air flow, the fan delivers a maximum airflow of 91 m³/h and a maximum static pressure of 47 Pa. The airflow is directed outwards over the struts. |
| Bearing type | ball bearings |
| 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. At nominal voltage and free airflow, the current consumption is 208 mA and the power consumption is 2.5 W. The motor has built-in locked-rotor protection with automatic restart, as well as reverse polarity protection via a diode. The direction of rotation is counter-clockwise when viewed from the rotor side. |
