The RER190-39/14/2TDMLO from EBM-Papst is a DC centrifugal fan with backward curved blades from the RadiCal series. The unit measures 190×190×69 mm and delivers up to 660 m³/h at free air flow. The 24 V DC EC-driven motor makes it energy-efficient and suitable for demanding applications.
The fan is ideal for ventilation systems, air handling units, and industrial equipment where a compact size and high airflow are needed. The flexible control option via PWM or analog 0–10 V signal allows for easy integration into existing control systems.

Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 660 m³/h |
| Speed | 2900 rpm |
| Power | 61 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan is supplied as a fan unit without a casing but with an inlet nozzle. The depth is 69 mm and the diameter is 190 mm with a weight of 0.858 kg. The mounting position for the shaft can be arbitrary. The unit is intended to be mounted between steel plates according to the specified measurement setup. |
| Casing | plastic, round |
| Impeller | The fan impeller is made of plastic and has a diameter of 190 mm. Airflow is axial in and radial out, which is typical for centrifugal fans. At free air flow and maximum speed, an airflow of 660 m³/h and a maximum static pressure of 445 Pa are achieved. The optimal operating point is 350 m³/h at 300 Pa. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor |
| Motor code | RER190-39/14/2TDMLO |
| Rotation direction | clockwise |
| Motor type | The motor is an EC motor (electronically commutated) with a nominal voltage of 24 V DC and a voltage range of 16–30 V. It has speed control via either PWM signal (1–10 kHz) or analog voltage 0–10 V. The motor is equipped with reverse polarity protection via a rectifier diode and automatic restart in case of locked rotor. Maximum speed is 2,900 rpm, and the motor has a built-in open collector tachometer output. |
