ebmpapst K3G400AQ2331 fan

EC centrifugal fan RadiPac K3G400AQ2331, 377.145.376 Industrial EC fan 3.0 kW with intelligent MODBUS control and IP55 protection class Fan EBM-PAPST K3G400-AQ23-31 is a high-efficiency centrifugal fan with an electronically commutated (EC) motor M3G150-FF and integrated control electronics. The RadiPac series model with 7 backward-curved aluminum blades and single-sided suction provides exceptional performance (up to 8880 m³/h) and high static pressure. Failure of the standard fan is critical — it leads to overheating and emergency shutdown of equipment. Installing an exact original replacement guarantees quick restoration of system operability.
