The 4118N/2H7P from EBM-Papst is a high-performance DC axial fan with a wall ring, designed for demanding applications where strong airflow and a compact size are crucial. The fan measures 119 × 119 × 38 mm and delivers up to 475 m³/h at maximum speed. With a voltage range of 36–60 V DC and built-in PWM control, it is flexible and easy to integrate.
Thanks to S-Force technology and a high static pressure of up to 1100 Pa, the 4118N/2H7P is excellently suited for dense electronics, control cabinets, and industrial systems where air resistance is high. The optional mounting position provides great freedom during installation.

| Airflow at 0 Pa | 475 m³/h |
| Speed | 500-9500 rpm |
| Power | 82 W |
| Voltage | 48 V DC VAC |
| Motor frame | The fan has a square metal housing with dimensions 119 × 119 × 38 mm and weighs 0.425 kg. Mounting is done with M4 screws (ISO 4762, degreased, without additional support or washer). The mounting position is optional with the shaft in any position. The maximum tightening torque during mounting over both flanges is 420 Ncm at the cable outlet corner and 600 Ncm at the other corners. |
| Casing | metal |
| Impeller | The fan impeller is made of plastic and is designed for axial airflow with air intake over the struts. At a maximum speed of 9500 rpm, the fan delivers a free airflow of up to 475 m³/h and a maximum static pressure of 1100 Pa. The optimal operating point is at 340 m³/h and 328 Pa. |
| Bearing type | ball bearing |
| Motor code | 4118 N/2H7P |
| Rotation direction | clockwise looking at the rotor |
| Motor type | The motor is a DC motor with electronic speed control via PWM signal (1–20 kHz) or analog control signal 0–5 V. The nominal voltage is 48 V DC with an allowed voltage range of 36–60 V. The motor has reverse polarity protection via N-channel FET and automatic restart in case of locked rotor. An internal fuse (5 A / 125 V) is installed for overload protection. |
