ebmpapst K3G450AQ2568 fan

EC centrifugal fan RadiPac K3G450AQ2568, 377.145.381 Industrial EC fan 2.64 kW with energy efficiency 69.2% and MODBUS interface Fan EBM-PAPST K3G450-AQ25-68 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 performance up to 7640 m³/h at static pressure 900 Pa. 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.
