Description
The ebm-papst K3G710-PV05-01 (also known as K3G710PV0501) is an industrial high-efficiency EC centrifugal fan module featuring a rigid cube support frame and a 5-blade backward-curved aluminum impeller driven by an integrated M3G200-LA motor. Operating across a wide three-phase supply of 380 to 480 VAC (50/60 Hz), this Ø710 mm (27.95 in) assembly delivers up to 17,990 CFM (30,565 m³/h) of airflow and reaches a maximum static pressure of 5.02 in H₂O (1,250 Pa) at a nominal power input of 7,050 W. Built for demanding commercial and industrial installations, it incorporates a corrosion-resistant galvanized steel support plate and inlet nozzle, an IP55-rated die-cast aluminum electronics housing, and sealed heavy-duty ball bearings. Control is managed via an integrated terminal box providing RS-485 MODBUS-RTU communication, 0–10 V / PWM speed inputs, an internal PID loop controller, and comprehensive active electronic thermal and locked-rotor protection.
