Description
ebm-papst S4E315-AC08-07 (also known as S4E315AC0807) is an industrial 315 mm (12.4 in) single-inlet AC axial fan equipped with an integrated protective guard grille engineered for short nozzle installations and powered by a robust M4E068-DF external rotor motor. Delivering an airflow capacity of up to 1,159.5 CFM (1,970 m³/h) at 1,530 RPM on 60 Hz and 1,035.9 CFM (1,760 m³/h) at 1,370 RPM on 50 Hz, this assembly is built for high aerodynamic throughput and continuous S1 duty across demanding commercial thermal systems. Mechanical construction features five black-coated sheet steel blades, heavy-duty ball bearings lubricated with anti-freezing grease, and rotor-side condensate drainage holes. The electrical subsystem is housed within an IP44 terminal box with an integrated 3 µF run capacitor and internal thermal overload protection.
Key Features
- External Rotor Drive: Powered by an integrated single-phase motor delivering up to 1,530 RPM with dependable S1 continuous duty.
- Sheet Steel Impeller: Five aerodynamically balanced black-coated steel blades provide rigid structural integrity and stable air volume delivery.
- Low-Temperature Bearings: Sealed precision ball bearings lubricated with anti-freezing grease ensure reliable rotation in sub-zero operational environments.
