The RLF100-11/12/2HP-200 from EBM-Papst is a compact DC centrifugal fan with backward-curved blades, designed for demanding applications where high pressure and reliable airflow in a small form factor are crucial. The fan measures 127 × 127 × 25.4 mm and is powered by 12 V DC with support for PWM speed control. Its compact FlatPak design makes it easy to integrate into tight spaces.
Thanks to its high static pressure of up to 500 Pa, the fan is ideal for cooling electronics, control cabinets, and medical equipment where air needs to be forced through dense ducts or filters.

Technical specifications
Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 80 m³/h |
| Speed | 6400 rpm |
| Power | 18.6 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan measures 127 × 127 × 25.4 mm and weighs 300 g. Mounting is done with ISO 4762 M4 screws without washers or additional support. Maximum tightening torque when mounting across both mounting flanges is 190 Ncm. The mounting position for the shaft can be in any direction. |
| Casing | mixed media, square |
| Impeller | The fan impeller is made of plastic and rotates clockwise when viewed towards the rotor. Airflow is axially inward and radially outward, classifying the unit as a centrifugal fan (blower). At a maximum speed of 6400 rpm, a maximum free airflow of 80 m³/h and a maximum static pressure of 500 Pa are achieved. The optimal operating point is 20 m³/h at 383 Pa. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with electronic speed control via PWM signal (35 Hz–10 kHz). The nominal voltage is 12 V DC with an allowed voltage range of 10–13.2 V. With free airflow and 100% PWM, the power consumption is 18.6 W and the current consumption is 1450 mA. The motor has reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The protection class is III. |
