The R3G250-AD62-30 from EBM Papst is a DC centrifugal fan with backward-curved blades, designed for demanding ventilation and air handling applications. The fan is powered by an energy-efficient 48 V DC EC motor and delivers an impressive airflow of up to 1,580 m³/h. With a compact size of 252×252×107 mm, it easily fits into confined installations.
The built-in M3G084-CA EC motor offers smart control via 0–10 V DC or PWM signal, making the fan ideal for energy-optimized systems in air handling units, industrial ventilation, and air treatment.
