Description
The ebmpapst W2D250-GA02-07 is a high-performance industrial AC axial fan with a nominal voltage of 400 VAC and an impeller size of 250 mm, specifically engineered for demanding thermal management in industrial control cabinets and power electronics. Driven by a robust three-phase M2D068-DF external rotor motor with a power consumption of 112 W at 50 Hz and 180 W at 60 Hz in a Star (Y) connection, this unit features a heavy-duty ball bearing system designed for long-term mechanical stability and continuous S1 duty. Its aerodynamic design with 5 black-coated sheet steel blades delivers a powerful airflow of 1050 m³/h at its optimum efficiency point while maintaining an overall static efficiency of 28.1%. Constructed with a galvanized sheet steel wall ring and a phosphated steel mounting ring coated in black plastic, this 2.9 kg fan provides a dependable and durable cooling solution with IP44 protection and F1-2 humidity class for industrial power supplies, medical imaging systems, and telecommunications infrastructure at the end.
