Description
The ebm-papst G2E085-AA01-01 (also known as G2E085AA0101) is an industrial single-inlet forward-curved AC centrifugal blower engineered with a rugged die-cast aluminum scroll housing and an integrated M2E042-CA external rotor motor. Designed for compact forced-air cooling, it delivers up to 50 CFM (85 m³/h) at 50 Hz and 60 CFM (100 m³/h) at 60 Hz while operating on a standard 230 VAC single-phase power supply. The assembly combines a galvanized sheet steel forward-curved wheel with heavy-duty ball bearings and an internal thermal overload protector (TOP) for dependable continuous S1 operation. Compact external dimensions of 128 × 118 × 88 mm (5.04 × 4.65 × 3.46 in) and versatile mounting flange orientations ensure seamless integration into space-restricted industrial enclosures and ducted process air assemblies.
Key Features
- Dual-Frequency Airflow: Produces up to 50 CFM at 2350 RPM (50 Hz) and 60 CFM at 2800 RPM (60 Hz).
- Rugged Metal Construction: Heavy-duty die-cast aluminum scroll housing paired with a corrosion-resistant galvanized sheet steel impeller.
- Integrated Motor Protection: Built-in internal thermal overload protector guards against overheating and unexpected operational rotor lockup.
- Precision Ball Bearings: Maintenance-free dual ball bearing architecture ensures continuous S1 duty across all mounting orientations.
- High Static Pressure Capability: Overcomes flow impedance up to 0.56 in H₂O in restricted ducted cooling pathways.
- Pre-Terminated Lead Connections: Factory PVC wire harness with crimped splices simplifies grounding and electrical hookup.
