The R3G280-RR05-N1 from EBM-Papst is an EC-driven centrifugal fan with backward-curved blades, specially designed for demanding railway applications. The fan combines a 280 mm RadiCal impeller with an integrated M3G084-DF EC motor, delivering up to 3,445 m³/h at 2,900 rpm. The cast aluminum housing and IP55 protection class provide robust protection in harsh environments.
The product complies with railway standards EN 50155, EN 45545-2 (HL3), and EN 61373 category 1B, making it ideal for ventilation in trains and rail vehicles. The integrated PID controller, soft start, and RS-485 MODBUS-RTU communication offer full control and easy integration into existing systems.
