Description
The ebm-papst R4E400-AR05-06 (also known as R4E400AR0506) is an industrial single-inlet, backward-curved AC motorized centrifugal impeller powered by an integrated M4E094-FA external rotor motor with an overall diameter of Ø400 mm (15.75 in). Engineered for high-aerodynamic-efficiency ventilation plenums, it operates on single-phase 230 VAC (50/60 Hz) to deliver up to 3535 m³/h (2080 CFM) and static pressures up to 550 Pa (2.21 in H₂O). The unit features a rugged 6-blade sheet aluminum impeller, dual maintenance-free precision ball bearings, and an 8 µF run capacitor circuit configured for continuous S1 operation. Comprehensive environmental shielding includes an IP54 ingress protection rating, Class F winding insulation, and internal thermal overload protection wired via a heat-resistant 6-conductor silicone lead.
Key Features
- Aerodynamic Impeller Geometry: Heavy-duty 6-blade backward-curved sheet aluminum impeller engineered for high static pressure and non-overloading air handling performance.
- M4E094 External Rotor Motor: Single-phase permanent split capacitor motor delivering high torque density and stable continuous S1 operation at all speeds.
- Robust Environmental Sealing: Rated to IP54 ingress protection with F4-1 environmental classification and corrosion-resistant black-painted external rotor surface.
- Integrated Thermal Protection: Factory-fitted thermal overload protector with basic insulation safely disconnects power during excessive winding temperatures or mechanical lockups.
- Dual Precision Ball Bearings: Sealed maintenance-free industrial bearing system permits dependable continuous operation across horizontal or vertical mounting orientations.
- Flexible Silicone Harness: Factory-installed silicone 6G 0.5 mm² multi-conductor cable with crimped splices ensures thermal durability in harsh ambient environments.

Applications
The ebm-papst R4E400-AR05-06 unhoused motorized impeller is specifically developed for ducted air handling units (AHUs), modular air filtration banks, and precision computer room air conditioners (CRAC/CRAH). Its high-efficiency backward-curved pressure profile makes it suitable for cleanroom Fan Filter Units (FFUs), commercial heat recovery ventilation (HRV) systems, and fume exhaust plenums. It also serves as a direct drop-in replacement for retrofitting roof-mounted industrial exhausters, industrial dehumidifiers, and electrical power inverter cooling chambers.
