The R3G500-RT04-H1 from EBM-Papst is a powerful EC centrifugal fan with backward-curved RadiCal blades, designed for demanding ventilation and air handling applications. With an impressive airflow of 3,860 m³/h and an IP55 protection rating, it delivers reliable performance even in harsh environments. The M3G084-GF EC motor type provides energy-efficient operation with an integrated PID controller, active PFC, and soft start.
The fan is ideal for air handling units, industrial ventilation, and air conditioning systems where high capacity, low noise, and smart control are crucial. Support for RS-485 MODBUS-RTU and 0–10 V DC/PWM control input makes it easy to integrate into modern automation systems.
