K3G560-PB31-03 ebmpapst

Description

The ebmpapst K3G560-PB31-03 is a massive, highly efficient 400 VAC 3-phase EC centrifugal module from the RadiPac series, engineered for advanced industrial and commercial thermal management. Integrating ebmpapst’s state-of-the-art GreenTech EC motor technology (M3G150-IF), this backward-curved, single-intake fan with a support bracket delivers a powerful air flow of up to 9600 m³/h at optimum efficiency, while maintaining a power consumption of 4250 W (4.15 kW). Housed with a die-cast aluminum electronics casing and a 5-blade sheet aluminum impeller, the unit weighs 51.8 kg and features an overall footprint size of 560 mm. Equipped with maintenance-free ball bearings and a robust IP55 protection rating, it operates reliably across an ambient temperature range of -40 °C to +40 °C. Boasting intelligent control inputs, an integrated PI controller, RS-485 MODBUS-RTU, and built-in electrical safeguards, the K3G560-PB31-03 provides a superior, precision-controlled cooling solution for sophisticated air handling units, large-scale automation systems, etc.
