ebm-papst S2D250-BH14-10 Condensing Fan Assembly

The ebm-papst S2D250-BH14-10 is a three-phase AC diagonal compact fan designed for condensing unit heat rejection in industrial refrigeration and heavy machinery applications. It features a 250 mm impeller diameter with sickle-shaped blades for optimized airflow and low noise emission. The outer rotor motor design integrates the rotor directly into the impeller hub, ensuring high mechanical stability and efficient heat dissipation from the windings. Electrical configuration supports 400 VAC three-phase supply at 50/60 Hz with a power consumption of 100 W at 50 Hz and 140 W at 60 Hz. Rated current is 0.22 A at 400 V. The fan delivers a nominal speed of 2,500 RPM at 50 Hz and 2,580 RPM at 60 Hz, generating an airflow of approximately 2,450 m3/h (50 Hz) to 2,810 m3/h (60 Hz) at a static pressure of 150 Pa. The unit is equipped with maintenance-free ball bearings and achieves an IP44 ingress protection rating. Housing and impeller are constructed from coated sheet steel and aluminum respectively, suitable for ambient temperatures ranging from -25 °C to +60 °C. Electrical connection is via two wire leads.
