Description
The ebmpapst R2D250-RA10-15 is a high-performance 400VAC three-phase AC centrifugal fan with an impeller size of Ø 250 mm, specifically engineered for intensive thermal management in industrial and commercial HVAC systems. Powered by a robust M2D068-EC motor, this single-intake backward-curved motorized impeller delivers optimized aerodynamic throughput and high reliability in a compact footprint. Operating at a nominal speed of 2,500 RPM under a 400V 50Hz Y connection, it efficiently draws 0.33A of current with a power consumption of 200W. Built with an IP44 protection class, H1+ environmental protection, 7 PA plastic blades, and precision ball bearings, the R2D250-RA10-15 ensures long-lasting continuous-duty operation. It also features built-in thermal overload protection and complies with strict safety standards including UL 1004-1 and CSA.
