The 4118N/2H3P from EBM-Papst is a compact DC tubeaxial fan for 48 V DC, built for demanding applications where high airflow and reliable operation are crucial. The fan delivers up to 310 m³/h at free air flow and reaches a maximum static pressure of 350 Pa at 6,000 rpm. The metal housing and ball bearings guarantee a long service life even in harsh environments.
Thanks to PWM speed control and a wide voltage range (36–60 V DC), the 4118N/2H3P is ideal for control cabinets, industrial equipment, and cooling systems where precise airflow control is required. Optional mounting position provides great flexibility during installation.

| Motor frame | The housing is made of metal with a square cross-section (119 × 119 mm) and a depth of 38 mm. ISO 4762 – M4 mounting screws (degreased, without spacer washer) are used for assembly. The maximum permissible torque is 420 Ncm for mounting over both mounting flanges with cable outlet corners, and 560 Ncm for other corners. The mounting position is optional. |
| Casing | metal |
| Impeller | The fan impeller is made of plastic and is mounted in a metal housing with dimensions 119 × 119 × 38 mm. Air intake is over the struts and the direction of rotation is clockwise when looking at the rotor. At free airflow, a maximum airflow of 310 m³/h and a maximum static pressure of 350 Pa are achieved at 6,000 rpm. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is an electronically controllable DC motor with PWM speed control in the 36–60 V DC voltage range, with a nominal voltage of 48 V. It has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The motor is equipped with an internal fuse (4 A, Littelfuse NANO2 451 series) and has a maximum starting current of 1,300 mA. Protection Class III applies to electrical safety. |
