K3G630-PC04-L1 ebmpapst 400V EC Centrifugal Fan

Description

The K3G630-PC04-L1 is a powerful, three-phase EC Centrifugal Fan module from ebmpapst’s RadiPac series, featuring the M3G150-NA external rotor motor and a 630 mm aluminum impeller with 5 blades. It operates on a 400 VAC nominal voltage with a wide range of 380 to 480 VAC (50/60 Hz). The fan delivers an impressive airflow of 14,085 m3/h and a high static pressure of 868 Pa at 1,610 RPM, consuming 5,250 W. The unit is highly robust with IP55 protection and H1 environmental rating, and features advanced EC technology including a MODBUS RTU interface, an integrated PI controller, and comprehensive electronic motor protection, making it ideal for large, complex HVAC systems.
