R3G250-RR01-H1 ebmpapst 230V 250mm EC Centrifugal Fan

Description

The ebmpapst R3G250-RR01-H1 is an ultra-high-performance EC Centrifugal Fan with an impeller size of 250 mm. Driven by the powerful M3G084-DF motor, this backward-curved fan is part of the aerodynamically optimized RadiCal series. Operating on a single-phase nominal 230 VAC (input range 200-277 VAC), it features a significant power input of 500 W and a rated current of 2.2 A. At its maximum load speed of 3740 RPM, it delivers a massive airflow of 1300.8 CFM (2210 m³/h) and can overcome static pressures up to 1100 Pa. Specifically engineered as a high-end “EC Retrofit Solution” for Fan Filter Units (FFU) and cleanroom ventilation, it includes integrated Modbus-RTU (RS485) for intelligent networking. With IP55 protection, F-class insulation, and a glass-fiber reinforced PA plastic impeller, it provides superior durability and efficiency (60.3% overall) for demanding industrial and medical environments.

Application
The R3G250-RR01-H1 is an industry-leading “EC Retrofit Solution” specifically tailored for high-performance Fan Filter Units (FFU) and mission-critical cleanroom ventilation. Its robust 500 W motor and 4.42 inAq static pressure capability make it ideal for overcoming the extreme resistance of ultra-dense HEPA/ULPA filters in semiconductor fabs and pharmaceutical labs. The integrated Modbus-RTU interface allows for large-scale networking, where hundreds of units can be synchronized and monitored from a central Building Management System (BMS). Its IP55 rating and die-cast aluminum construction ensure reliable performance in harsh industrial environments, while the aerodynamically optimized RadiCal impeller maintains high efficiency and reduced noise levels, making it the definitive choice for precision cooling in server rooms and large-scale HVAC systems.
