Description
The ebmpapst R2D280-RB06-01 is a high-performance 230/400VAC three-phase AC centrifugal fan with an impeller size of Ø 280 mm and external dimensions of 295 x 295 x 170 mm, specifically engineered for intensive thermal management in industrial ventilation and commercial HVAC systems. Powered by a robust M2D074-GA motor, this single-intake backward-curved motorized impeller delivers high-volume airflow and static pressure capabilities. Operating at a nominal speed of 2,500 RPM under 230V Δ / 400V Y 50Hz configurations, it efficiently draws 1.58 / 0.91 A with a maximum power consumption of 570 W. Built with an IP44 protection rating, Class F insulation, 6 PP plastic blades, and precision ball bearings, the R2D280-RB06-01 weighs 5.4 kg and ensures reliable, continuous-duty performance in demanding thermal environments.
