K3G310-BE90-N1/F01 ebmpapst 400V 400mm EC centrifugal fan

Description

The ebmpapst K3G310-BE90-N1/F01 is a premium-grade RadiCal EC centrifugal fan module integrated within a 400 x 400 x 245.5 mm aluminum support structure, designed for heavy-duty railway and industrial applications. Operating on a 3-phase 380 – 480 VAC supply, this module utilizes the M3G112-EA motor to deliver a powerful 1300 W output at 2900 RPM. The 310 mm sheet aluminum backward-curved impeller and galvanized inlet nozzle are engineered for high-pressure efficiency and compliance with EN 45545-2 (HL3) and EN 50155 fire and vibration safety standards. Featuring IP55 protection, an integrated PID controller, and RS-485 MODBUS-RTU interface, this fan module provides advanced thermal management and long-term reliability in extreme environments from -40 °C to 60 °C.
