The RER133-41/14/2TDP from EBM-Papst is a DC centrifugal fan with backward-curved blades, designed for integration into applications where compact size and high airflow are combined. The fan measures 133×133×91 mm and delivers up to 540 m³/h at free airflow. It is powered by an EC motor (electronically commutated) with a wide voltage range of 16–36 V DC.
Thanks to integrated PWM control and reverse polarity protection, the RER133-41/14/2TDP is ideal for demanding industrial applications, medical equipment, and advanced ventilation systems where precise speed control and operational reliability are crucial.

Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 540 m³/h |
| Speed | 6000 rpm |
| Power | 94 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan is supplied without a chassis (blower without chassis) and is equipped with an intake nozzle. The unit has a depth of 91 mm and a diameter of 133 mm, and weighs 0.89 kg. The shaft can be mounted in any position. The fan is designed for integration into an application and is measured between two steel plates (140 x 140 mm) under specified test conditions. |
| Casing | plastic |
| Impeller | The fan impeller is made of plastic and has a diameter of 133 mm. The airflow is axial in and radial out, which is typical for centrifugal fans. With free air intake and 6000 rpm, a maximum airflow of 540 m³/h and a maximum static pressure of 745 Pa are achieved. The optimal operating point is 315 m³/h at 565 Pa. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor |
| Motor code | RER133-41/14/2TDP |
| Rotation direction | clockwise |
| Motor type | The motor is an EC motor (electronically commutated) without a chassis, designed for 24 V DC with a voltage range of 16–36 V. It features built-in speed control via PWM signal (1–10 kHz) and reverse polarity protection via a P-channel FET. In case of a locked rotor, automatic restart occurs, and the current consumption at locked rotor is approximately 1300 mA at nominal voltage. The motor is supplied without a chassis but with an intake nozzle. |
