The R3G280-AC66-30 from EBM-Papst is a compact EC centrifugal fan measuring 280x121 mm, powered by an electronically commutated 48 V DC motor. It combines high efficiency with an impressive airflow of 1270 m³/h, making it ideal for demanding industrial applications. Thanks to EC technology, it offers intelligent control, low energy consumption, and a long service life.
The fan is well-suited for ventilation units, cooling systems, and air handling units where a compact design and flexible mounting position are important. PWM control and tach output make it easy to integrate into modern control systems.
