Description
The ebm-papst D2D133-AB02-07 (also known as D2D133AB0207) is an industrial dual-intake forward-curved AC centrifugal blower with integrated scroll housing, powered by an external rotor M2D068-DF three-phase motor across a 180 mm × 173.5 mm × 215.0 mm (7.09 in × 6.83 in × 8.46 in) compact footprint. Operating on 400 VAC in star (Y) connection at 50/60 Hz, the unit delivers up to 485 CFM (825 m³/h) airflow and nominal operating speeds reaching 2170 RPM (50 Hz) and 2640 RPM (60 Hz) under 225 W and 215 W power ratings. Robust mechanical engineering features a galvanized sheet steel scroll housing, black-painted forward-curved steel impeller, galvanized steel guard grille, and maintenance-free dual ball bearings rated for IP44 ingress protection in continuous S1 duty. Electrical termination is provided via an axial silicone multi-conductor cable (3× 0.5 mm²) terminating in 2.8 mm × 1.0 mm flat quick-connect receptacles.
Key Features
- High-Efficiency Aerodynamics: Dual-inlet forward-curved galvanized steel impeller generates 485 CFM against continuous industrial back pressures.
- Three-Phase 400VAC Motor: Integrated external rotor M2D068-DF motor supports star wiring for stable continuous S1 operation.
- Heavy-Duty Construction: Rugged galvanized sheet steel scroll housing with RAL 9006 powder-coated intake guard grille.
- Harsh Environment Sealing: Rated IP44 with F2-2 environmental moisture protection and integrated rotor condensation drainage holes.
- Flexible Power Termination: Axial high-temperature silicone cable fitted with crimped 2.8×1 mm flat quick-connect slide receptacles.
