The R3G225-RH19-01 from EBM-Papst is an EC-driven centrifugal fan with backward-curved blades, designed for demanding ventilation and air handling applications. The fan delivers an airflow of up to 1,135 m³/h with a power consumption of only 107 W. Thanks to EC technology, you get high efficiency, soft start, and easy control via 0–10 V DC or PWM signal.
The fan is ideal for air handling units, heat pumps, and industrial ventilation where energy efficiency and operational reliability are crucial. The optional mounting position provides great flexibility during installation.
- RadiCal fan impeller made of PA plastic, 225 mm diameter, 7 backward-curved blades
