The 4154N/2H7P from EBM-Papst is a high-performance DC axial fan with a wall ring, built for demanding applications where high airflow and a compact form factor are critical. The fan measures 119 × 119 × 38 mm and delivers up to 475 m³/h at free air flow. With S-Force technology and a metal casing, it is designed for long-lasting and reliable use.
Thanks to a wide voltage range (16–30 V DC) and support for both PWM and analog control, the 4154N/2H7P is ideal for control cabinet cooling, industrial equipment, and ventilation systems where precise airflow control is required.

|---|---|
| Airflow at 0 Pa | 475 m³/h |
| Speed | 9500 rpm |
| Power | 83 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan is mounted with ISO 4762 M4 screws, degreased and without washers. Maximum torque at the mounting flanges varies depending on the corner: 420 Ncm at the cable outlet corner and 600 Ncm at the other corners. The mounting position of the shaft can be in any direction. |
| Casing | metal |
| Impeller | The fan impeller is made of plastic and mounted in a metal frame with dimensions 119 x 119 x 38 mm. At a maximum speed of 9500 rpm and free airflow, the fan impeller delivers an airflow of up to 475 m³/h and a maximum static pressure of 1100 Pa. The optimal operating point is 340 m³/h at 328 Pa. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with electronic speed control via a PWM signal (1–20 kHz) or an analog control signal of 0–5 V. The rated voltage is 24 V DC with an allowed voltage range of 16–30 V. The motor has reverse polarity protection via an N-channel FET, as well as automatic restart in case of a locked rotor. An internal fuse (8 A) is installed to protect the electronics. |
