K3G310-PH38-32 ebmpapst 400V 310mm EC Centrifugal Fan

Description

The ebmpapst K3G310-PH38-32 is an industrial-grade, three-phase RadiCal EC centrifugal motorized impeller designed for high-capacity air management in mission-critical HVAC and industrial cooling systems. Operating on a 380 – 480 VAC three-phase supply at 50/60 Hz, this unit features a high-performance integrated EC motor that delivers an input power of 1800 W at a nominal speed of 3410 RPM. The 310 mm backward-curved impeller, crafted from glass-fiber reinforced PA6 plastic, is optimized for peak aerodynamic efficiency and low noise emissions. Equipped with advanced electronics supporting RS485 MODBUS RTU and 0-10 VDC control, the K3G310-PH38-32 provides an IP54-rated, high-pressure thermal solution for demanding environments ranging from -25 °C to 60 °C.
