Description
The ebmpapst R2E225-AT51-14 is a high-performance 230VAC single-phase AC Centrifugal Fan, featuring backward-curved impellers in a compact motorized impeller design. Driven by the M2E068-DF motor with integrated thermal overload protection (TOP), this 225 mm impeller size fan is specifically engineered for slim-profile cabinet cooling, ventilation modules, and electronic equipment thermal management. Operating on a 230 VAC supply, it delivers a Power Consumption of 105 W / 145 W and a Current Draw of 0.46 A / 0.64 A at rated speeds of 2650 / 2950 RPM. Featuring a glass-fiber reinforced PA6 plastic impeller with 11 blades and a high-quality 3.0 µF / 450 VDB capacitor system, it ensures superior aerodynamic efficiency, IP44-rated protection, and reliable continuous S1 operation in demanding environments at the end.
