Description
The ebmpapst R2E220-AA40-05 is a high-performance, single-inlet centrifugal fan featuring a backward-curved motorized impeller. This unit integrates the M2E068-BF single-phase AC external rotor motor directly into the impeller hub, a hallmark of original engineering that optimizes cooling efficiency while minimizing installation depth. The impeller is precision-molded from fiberglass-reinforced polyamide (PA6), offering superior chemical resistance and reduced rotational inertia compared to metallic alternatives. Designed for continuous operation, the motor utilizes maintenance-free ball bearings and includes an internally wired thermal overload protector to prevent failure under stall conditions. This specific configuration is engineered for applications requiring high static pressure development in restricted spaces. We verify technical compatibility for seamless integration into existing ventilation architectures and prioritize supply chain management to minimize lead time for critical spares.

Industrial Application Profile:
This motorized impeller is specifically calibrated for use in precision cooling units for telecommunications base stations and electronic cabinet cooling where high back-pressure resistance is required. The backward-curved blade geometry ensures the motor does not overload if the system runs with zero static pressure (free air), making it a fail-safe solution for variable air volume (VAV) systems and heat exchangers requiring consistent airflow against dense filter media.
