Description
The ebmpapst W2E250-HJ28-01 is a high-performance 230VAC single-phase AC axial compact fan featuring an impeller size of Ø 250 mm and external dimensions of 280 x 280 x 80 mm. Powered by an M2E068-DF motor, this 7-blade sickled-blade axial fan (S series) with a die-cast aluminium wall ring delivers high-volume airflow and reliable thermal management. Operating at a rated speed of 2,600 / 2,850 RPM under 50 / 60 Hz, it draws a maximum current of 0.51 / 0.7 A with a power consumption of 115 / 160 W and utilizes an integrated 3.5 µF / 400 VDB motor capacitor. Built with a black-coated sheet steel blade design, precision ball bearings, Insulation Class B, and an IP44 protection rating, it weighs 3.2 kg and supports continuous S1 operation across ambient temperatures ranging from -25 to +70 °C.
