The 4118N/2H3 from EBM-Papst is a compact DC axial fan with a wall ring, measuring 119 × 119 × 38 mm. The fan is built for demanding environments with a metal housing and ball bearings, and delivers an impressive 310 m³/h at free air flow. S-Force technology combines high airflow with operational reliability in a single compact format.
Thanks to a wide voltage range of 36–60 V DC, the 4118N/2H3 is well suited for industrial cooling equipment, control cabinets, and power electronics where stable and efficient air cooling is crucial. Optional mounting position and built-in reverse polarity protection simplify installation and increase operational reliability.

| Motor frame | The fan has a metal housing with dimensions of 119 × 119 × 38 mm and a weight of 0.39 kg. Mounting is done with ISO 4762 M4 screws, and the mounting position for the axis can be in any direction. The maximum torque for mounting is 420 Ncm at the cable outlet corner and 560 Ncm at the other corners. |
| Casing | metal |
| Impeller | The impeller is made of plastic and rotates clockwise when viewed from the rotor side. The airflow is drawn in over the struts. At 6000 rpm and free airflow, the fan delivers up to 310 m³/h and a maximum static pressure of 350 Pa. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with electronic speed control and a nominal voltage of 48 V DC (voltage range 36–60 V DC). It has built-in reverse polarity protection via a rectifier diode and automatic restart in case of locked rotor. An internal Littelfuse NANO2 2 A fuse is installed. Power consumption at free airflow is 20 W at nominal voltage. |
