A2D250-AA26-51 ebmpapst 400VAC 250mm AC Axial Fan

Description

The ebmpapst A2D250-AA26-51 is a high-performance 400VAC three-phase AC axial fan featuring a fan size of 250 mm. Powered by an M2D068-DF motor with Y wiring, this straight-blade (A series) axial fan delivers reliable airflow and static pressure performance. Operating at a rated speed of 2,670 / 2,900 RPM under 50 / 60 Hz, it draws a maximum current of 0.25 / 0.30 A with a power consumption of 125 / 175 W. Constructed with painted black sheet steel blades, precision ball bearings, and an IP44 protection rating (installation- and position-dependent as per EN 60034-5), it weighs 2.02 kg and supports continuous S1 operation across ambient temperatures ranging from -25 to +70 °C (at 50 Hz) and -25 to +50 °C (at 60 Hz).
