Description
The ebmpapst R2E120-BB76-11/A01 is a high-performance AC backward-curved centrifugal fan with a nominal voltage of 230 VAC and an impeller diameter of 120 mm, specifically engineered for robust thermal management in compact industrial enclosures. Driven by a high-torque M2E052-BF external rotor motor with a power consumption of 20/19 W, this unit features a heavy-duty dual ball bearing system designed for long-term mechanical stability and continuous S1 duty. Its aerodynamic backward-curved impeller, constructed from high-quality PA plastic, delivers a powerful balance of significant airflow and stable static pressure without the need for a scroll housing. Built with a robust galvanized sheet steel base and featuring IP44 protection with Class F insulation, this 0.7 kg fan provides a dependable and durable cooling solution with thermal overload protection for industrial power supplies, server racks, and telecommunications cabinets at the end.
