Description
The ebmpapst R3G310-AN43-71 is a high-efficiency EC centrifugal fan featuring a backward-curved, single-intake impeller design for professional ventilation, HVAC and industrial air movement applications. Equipped with an integrated EC motor and intelligent control electronics, this fan provides efficient operation, variable speed control and reliable airflow performance.
The R3G310-AN43-71 uses the M3G084-FA EC motor and operates with a 230VAC nominal voltage and a wide 200-277VAC voltage range. The integrated electronics support 0-10VDC and PWM control input, allowing flexible speed adjustment for different system requirements.
Designed with a 310 mm impeller size, the fan features a sheet aluminum impeller, die-cast aluminum electronics housing and a black painted rotor surface. The six-blade backward-curved impeller provides efficient air movement and stable pressure performance for demanding ventilation systems.
With a rated power consumption of 470 W, airflow performance of 1810 m³/h and pressure increase of 507 Pa, the ebmpapst R3G310-AN43-71 is designed for applications requiring energy-efficient airflow control, long operating life and reliable thermal management.
