K3G250-RR17-H9 A5E37084910 ebmpapst 230V EC Centrifugal Fan

Description

The ebmpapst K3G250-RR17-H9 (Siemens A5E37084910) is a high-performance 230 VAC EC centrifugal fan with dimensions of Ø 250 x 156 mm. Engineered in Germany as an OEM cooling component for Siemens drive systems, this single-phase backward-curved fan features an integrated Variable Speed Drive (VSD), dual ball bearings, and IP55 ingress protection for demanding industrial environments. Delivering a Working Air Flow of 1412.00 CFM (2400.0 m³/h / 40.00 m³/min) and a Static Pressure Increase of 86.70 mmH₂O (850.0 Pa / 3.41 inH₂O) at a rated speed of 3,100 RPM, it operates on a nominal voltage of 230 VAC within an operating voltage range of 200 – 277 VAC (50/60 Hz). At rated operation (230 V), it features a Max. Current Draw of 1.3 A with a Max. Power Consumption of 300 W and achieves an overall static efficiency of 49.7%. Built for continuous heavy-duty service, it operates in ambient temperatures up to +60 °C and holds safety certifications including CE and RoHS.
