The G1G146-BA07-52 from EBM-Papst is a compact EC centrifugal fan with a 146 mm forward-curved single inlet impeller. Powered by an electronically commutated DC motor, it delivers up to 470 m³/h air flow at 2,200 rpm. The fan is excellently suited for demanding applications where energy efficiency and precise control are important.
Thanks to the 0–10 V DC or PWM control input, the speed can be easily adjusted as needed. Soft start and built-in protection against reverse polarity and locked rotor make it reliable in continuous operation (S1). The cast aluminum housing provides a robust construction with flexible mounting positions.
