Description
The ebm-papst R2E210-AA34-05 (also designated as R2E210AA3405) is a specialized Ø210 mm (8.27 in) single-inlet AC centrifugal hot air circulation blower driven by an integrated M2E068-DF external rotor motor. Operating on a 230 VAC, 50 Hz single-phase electrical supply with a 2.0 µF operating capacitor, it delivers a nominal rotational velocity of 2500 RPM and free-air throughput of 310 CFM (525 m³/h) against system backpressures reaching 1.36 in H₂O (340 Pa). Built with a 6-blade stainless sheet steel impeller mounted onto a hot-dip galvanized support plate with integrated one-sided vibration damping, the assembly ensures mechanical resilience in elevated-temperature environments. Standard connectivity features an internal thermal overload protector (TOP), dual ball bearings, silicone power cabling, and an integrated Hall IC speed sensor circuit for precision feedback.
Key Features
- Aerodynamic High-Static Impeller: Delivers 310 CFM (525 m³/h) free air and generates up to 1.36 in H₂O backpressure.
- Corrosion-Resistant Metallurgy: Fabricated with high-grade stainless sheet steel blades and a hot-dip galvanized mounting plate for thermal durability.
- Integrated Vibration Isolation: Engineered with dedicated one-sided elastomeric damping mounts to eliminate structural acoustic resonance and mechanical vibration transfer.
- Active Hall IC Feedback: Equipped with an auxiliary three-wire Hall sensor assembly providing real-time rotational pulse monitoring to external controllers.
- High-Temperature Duty Architecture: Features silicone 4G 0.5 mm² harness, Class F motor winding insulation, and internal thermal overload protector.
- Robust External Rotor Drive: Powered by the M2E068-DF motor utilizing heavy-duty dual ball bearings rated for S1 continuous operation.

Applications
The ebm-papst R2E210-AA34-05 is primarily deployed as an induced draft or forced hot air circulation blower within automated pellet stoves, biomass boilers, and commercial solid-fuel heating systems. It serves as a vital thermal exchange blower in commercial bakery ovens, industrial drying kilns, heat treatment tunnels, and high-temperature curing enclosures. Additionally, maintenance technicians rely on this motorized impeller assembly for MRO replacement across ducted exhaust flues, flue gas recirculation units, and ventilation heat recovery systems.
