The R1G225-AG15-11 from EBM-Papst is a DC-powered centrifugal fan with backward-curved blades, designed for energy-efficient and quiet operation. This compact unit combines a 225 mm fan impeller with an integrated EC motor (M1G074-CF) powered by 48 V DC. With an airflow of up to 1175 m³/h, it is perfectly suited for demanding ventilation and air handling applications.
Thanks to its control input for 0–10 V DC or PWM signal, the fan offers easy integration into modern control systems. It is well-suited for air handling units, heat pumps, air treatment units, and industrial ventilation where precision control and reliable operation are crucial.
- Airflow: up to 1175 m³/h
- Voltage: 48 V DC (range 36–49 V DC)
- Power: 115 W, speed 2850 rpm
- EC motor with soft start and current limit control
- Control input: 0–10 V DC or PWM, tach output 3 pulses/revolution
- Protection: reverse polarity and locked rotor protection, IP44
- Ball bearings for long service life, mounting position optional
- Connection: PVC cable AWG20 with 4-pin Tyco connector
