K3G280-BC01-N3 ebmpapst 400V 400mm EC Centrifugal Fan

Description

The ebmpapst K3G280-BC01-N3 is a heavy-duty RadiCal EC centrifugal fan module housed in a precision-engineered 400 x 400 x 273.4 mm aluminum support structure, specifically designed for high-pressure industrial cooling and demanding HVAC applications. Operating on a 3-phase 400 VAC supply (380 – 480 VAC), this integrated module delivers 940 W of power to drive its 280 mm backward-curved impeller at a nominal speed of 3140 RPM, generating a formidable static pressure of 1000 Pa. The expanded 273.4 mm installation depth ensures optimal aerodynamic clearance and robust mounting stability. Featuring IP55 protection, integrated RS-485 MODBUS-RTU control, and an extensive operating range from -40 °C to 60 °C, the K3G280-BC01-N3 provides a reliable, high-performance air management solution for mission-critical infrastructure.
