Ventola ebmpapst K3G500PB3332

EC centrifugal fan RadiPac K3G500PB3332, 377.145.390 Industrial EC fan for air handling units (AHU) with MODBUS control Fan EBM-PAPST K3G500-PB33-32 is a high-efficiency centrifugal fan with an electronically commutated (EC) motor and integrated control electronics. Model of the RadiPac series is specially designed for air handling units (AHU), providing an optimal balance between high performance and energy efficiency. Thanks to the "all-in-one" design (Electronics on Board), the required control functions are already built into the fan. 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.
