The R3G146-EC50-01 from EBM-Papst is a compact centrifugal fan with forward-curved blades and an integrated EC motor, designed for efficient and quiet operation in demanding applications. The fan delivers an impressive airflow of 815 m³/h at 2,750 rpm and is powered by an electronically commutated 26 V DC motor. The integrated control electronics support both 0–10 V DC and PWM control signals, allowing for easy integration into modern systems.
The fan is ideal for applications where energy-efficient and precisely controlled ventilation is required, such as in industrial equipment, refrigeration units, and air handling systems.
