The W3G800-GA77-51 from EBM-Papst is a large EC axial fan with a wall ring, designed for demanding ventilation applications where high airflow and energy efficiency are crucial. The fan is equipped with the three-phase EC motor M3G112-EA and HyBlade fan impellers with sickle-shaped blades, providing impressive performance with up to 8,145 m³/h at a low noise level of 54 dB(A).
Thanks to the built-in PID controller, soft start, and RS-485 MODBUS-RTU communication, the fan is perfectly suited for modern control systems in industrial ventilation, air handling units, and large ventilation systems.
