The RG140-22/14N/2TDPU from EBM-Papst is a DC centrifugal fan with backward-curved blades, designed for demanding environments where humidity and salt air impose high requirements. The fan measures 180×180×40 mm and delivers up to 118 m³/h at free airflow. Its high IP68 rating makes it a robust choice for industrial and marine applications.
Thanks to PWM control and tacho signal, the fan is excellent for systems where precise speed control and feedback are important, such as cooling electronics, control cabinets, and ventilation equipment in humid environments.

|---|---|
| Airflow at 0 Pa | 118 m³/h |
| Speed | 2500 rpm |
| Power | 9.3 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan is mounted via a flange using ISO 4762 M4 screws, degreased and without a washer. The housing measures 180×180×40 mm and weighs 0.75 kg. The motor shaft can be mounted in any position. The maximum tightening torque during assembly is 70 Ncm for all corners. |
| Casing | mixed media, 180×180×40 mm |
| Impeller | The fan impeller is made of plastic and is part of a centrifugal fan (blower) where air flows in axially and out radially. At free air flow (Δp = 0), a maximum air flow of 118 m³/h is achieved at 2500 rpm. The maximum static pressure is 215 Pa. The optimal operating point is 43.0 m³/h at 157 Pa. |
| Bearing type | ball bearing |
| IP class | IP68 |
| Motor protection | automatic restart at locked rotor |
| Motor code | RG140-22/14N/2TDPU |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with electronic speed control via PWM signal (1–10 kHz, typically 5 kHz). Nominal voltage is 24 V DC with a permissible voltage range of 20.4–27.6 V. The motor has reverse polarity protection via a rectifier diode and automatic restart in case of locked rotor. IP68 protection class makes the motor suitable for use in humid and salty environments. |
