The R3G450-RT03-H1 from EBM Papst is an EC-driven centrifugal fan with backward-curved blades, developed for demanding ventilation and air handling applications. The fan delivers an impressive airflow of 3,690 m³/h at 278 Pa and is powered by an electronically commutated motor with a single-phase 230 V AC supply. Thanks to the RadiCal design, high efficiency is achieved with a low noise level of only 59 dB(A).
The fan is excellent for use in air handling units, industrial ventilation, and air treatment where energy efficiency and control options are important. The integrated PID controller and support for RS-485 MODBUS-RTU, as well as 0–10 V DC/PWM control input, make it easy to integrate into modern automation systems.
- Airflow: 3,690 m³/h at 278 Pa

| Motor frame | The fan weighs 7.5 kg and the mounting position is horizontal shaft or rotor downwards as standard; mounting with rotor upwards is possible upon request. Condensate drainage is located on the rotor side. An accessory inlet ring (part no. 45901-2-2943) is not included in the delivery and must be ordered separately. Screw fastening with a maximum 16 mm clearance hole is specified in the product drawing. |
| Casing | die-cast aluminum, electronics enclosure |
| Impeller | The fan impeller is made of PP plastic and has 6 backward-curved blades with single-sided intake. The rotor diameter is 450 mm and the rotor surface is black-painted. The fan impeller is designed according to the RadiCal principle for centrifugal fans and achieves a total efficiency of 61% at optimal operating point. At nominal operating conditions, the fan delivers 3690 m³/h at 278 Pa pressure increase. |
