The 8452/2L is a compact DC axial fan from EBM-Papst, designed for efficient cooling in space-constrained applications. The fan delivers 30 m³/h at 1,700 rpm and is powered by 12 V DC. With a square plastic housing measuring 80 × 80 × 25 mm, it is ideal for electronic enclosures, medical equipment, and industrial apparatus.
Thanks to the integrated speed signal with open collector output, the 8452/2L is a good choice when monitoring functionality is required. Optional mounting position and low profile provide great flexibility in design.

|---|---|
| Airflow at 0 Pa | 30 m³/h |
| Speed | 1700 rpm |
| Power | 0.41 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan has a square plastic housing with dimensions 80 × 80 × 25 mm and weighs 110 grams. Mounting is done with ISO 4762 M4 screws, degreased and without washers. Tightening torque varies depending on the corner: the cable exit corner tolerates a maximum of 30 Ncm and the other corners a maximum of 50 Ncm. The mounting position for the shaft can be arbitrary. |
| Casing | plastic, square |
| Impeller | The fan wheel is made of plastic and mounted on a ball-bearing axle for long service life. The airflow is directed over the struts. Under nominal operating conditions, the fan provides a maximum free airflow of 30 m³/h and a maximum static pressure of 12 Pa at 1,770 rpm. |
| Bearing type | ball bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 12 V and a voltage range of 8–15 V. At nominal voltage and free airflow, the current consumption is 34 mA and the power consumption is 0.41 W. The motor has reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The service life is up to 80,000 hours (L10) at 40 °C ambient temperature. |
