K3G630-AR02-01 ebmpapst 400VAC 630mm EC Centrifugal Fan

Description

The ebmpapst K3G630-AR02-01 is a high-efficiency RadiPac EC centrifugal fan unit with a nominal voltage of 400 VAC and an impeller size of 630 mm, specifically engineered for advanced thermal management in high-density data centers and large-scale industrial ventilation systems. Driven by a massive three-phase M3G200-HF EC external rotor motor with an integrated electronic control system and a power consumption of 6750 W, this unit features a heavy-duty ball bearing system designed for long-term mechanical stability and continuous S1 duty. Its aerodynamic design with 7 aluminum sheet blades delivers a massive airflow of 14635 m³/h at its rated speed of 1500 RPM, achieving a total pressure increase of 1016 Pa with an overall static efficiency of 63.5%. Constructed with a galvanized and plastic-coated (RAL 7035) steel support structure and an integrated PID controller with RS-485 MODBUS RTU interface, this 125 kg fan unit provides an intelligent and extremely powerful air-moving solution with IP54 protection and Class F insulation for precision air conditioning units, clean rooms, and large-scale industrial AHU infrastructure at the end.
