The 4412/2HP is a compact axial fan from EBM-Papst in the DC fans category, designed for efficient ventilation in electronics, control cabinets, and industrial equipment. The fan measures 119 × 119 × 38 mm and delivers up to 240 m³/h at free airflow. Its square plastic housing and ball bearing construction make it a robust choice for demanding environments.
With PWM control and a wide voltage range (7–15 V DC), the 4412/2HP is ideal where variable speed control is required. Optional mounting position and a 310 mm connection cable provide great flexibility during installation.

Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 240 m³/h |
| Speed | 4300 rpm |
| Power | 8.1 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan is mounted via a flange using ISO 4762 M4 screws (degreased, without washer, and without additional support). The mounting position for the shaft is optional. The maximum tightening torque when mounting across both mounting flanges is 80 Ncm for all corners. |
| Casing | plastic, square |
| Impeller | The impeller is made of plastic and is mounted in a 119 × 119 × 38 mm plastic casing. The airflow direction is out over the struts (air outlet over struts). With free airflow (ΔP = 0) and 4,300 rpm, a maximum airflow of 240 m³/h and a maximum static pressure of 175 Pa are achieved. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is an electronically speed-controlled DC motor with PWM control (1–10 kHz, typically 5 kHz). Nominal voltage is 12 V DC with an operating range of 7–15 V. The motor has built-in reverse polarity protection via a rectifier diode and automatic restart in case of locked rotor. Locked-rotor current is approximately 3,800 mA at nominal voltage. |
