Description
The ebmpapst A2D250-AA02-02 is a high-performance three-phase AC axial fan featuring straight blades (A series) driven by an M2D068-DF motor. Engineered for a nominal voltage of 400 VAC at 50 / 60 Hz in star connection (Y), it delivers multi-frequency performance under running at free air (rfa) conditions: operating at 50 Hz, it provides a speed of 2,650 min⁻¹, drawing a power input of 110 W, a current draw of 0.22 A, and a max. back pressure of 205 Pa with a max. ambient temperature of 70 °C; operating at 60 Hz, it provides a speed of 2,950 min⁻¹, drawing a power input of 160 W, a current draw of 0.26 A, and a max. back pressure of 300 Pa with a max. ambient temperature of 40 °C. Constructed with an impeller size of 250 mm, a mass of 2.05 kg, black-coated sheet steel blades, black-coated rotor surface, and 5 blades, this unit ensures robust industrial operation. It features ball bearings, clockwise direction of rotation seen on the rotor, “A” direction of air flow, IP44 degree of protection, insulation class “B”, F2-2 humidity class, and continuous S1 duty mode with shaft horizontal or rotor on bottom mounting position. It includes rotor-side condensate discharge holes, lateral cable exit, leakage current < 0.75 mA, protection class I, conformity with EN 60335-1, and CCC approval. It operates reliably within a transport and storage temperature range of -40 to +80 °C.
