Description
The ebm-papst W6E630-NT03-01 (also known as W6E630NT0301) is an industrial 630 mm (24.8 in) AxiBlade AC axial fan assembly featuring aerodynamically optimized sickle-shaped blades and an integrated M6E110-GF external rotor motor enclosed in a robust galvanized sheet steel wall ring housing with protective guard grille. Operating on a single-phase 230 VAC 50 Hz supply with an external 14 µF run capacitor, it delivers a maximum free-air throughput of 6,770 CFM (11,500 m³/h) and achieves a maximum back pressure capability of 0.48 in H₂O (120 Pa) at 535 W power input. Engineered for severe thermal and environmental duty, this fan integrates continuous-duty ball bearings, IP54 ingress sealing, Class F insulation, and an auto-reset thermal overload protector (TOP) wired to an onboard terminal box.
Key Features
- AxiBlade Aerodynamic Profile: Five sickle-shaped PP plastic blades maximize static efficiency up to 37.3% while significantly suppressing turbulence noise.
- Heavy-Duty Wall Housing: Galvanized sheet steel frame and steel safety grille with black RAL 9005 plastic protective coating.
- Robust External Rotor Motor: Powered by the single-phase M6E110-GF drive paired with a 14 µF 450 VDB run capacitor.
- Environmental Protection: IP54 rating and H2 moisture classification ensure reliable continuous S1 duty in wet, dusty conditions.
- Integrated Motor Protection: Internal auto-reset thermal overload switch (TOP) prevents winding damage under extreme back pressure or elevated ambient.
- Versatile Mounting Architecture: Designed for horizontal or rotor-down shaft installation featuring integrated rotor condensation drainage holes and standard terminal box.
