Description
ebm-papst W2E143-AB09-06 (also known as W2E143AB0906) is an industrial-grade AC axial compact fan driven by an integrated M2E052-BF single-phase capacitor motor enclosed in a robust 171.5 mm diameter by 51.0 mm (6.75 in x 2.01 in) die-cast aluminum round wall ring. Engineered for versatile thermal management, it operates on a 230 VAC 50/60 Hz electrical supply to deliver up to 247.2 CFM (420.0 m³/h) at 2800 RPM and 288.4 CFM (490.0 m³/h) at 3300 RPM. Aerodynamic efficiency is maximized through five coated sheet-steel blades, precision dual ball bearings, and continuous S1 duty operation. The assembly incorporates internal thermal overload protection (TOP), an IP20 ingress rating, and dual 2.8 x 0.5 mm flat spade terminals for straightforward electrical integration.
Key Features
- Rugged Metal Construction: Combines a durable die-cast aluminum wall ring with black-coated sheet steel blades for demanding environments.
- High Aerodynamic Output: Generates up to 288.4 CFM (490.0 m³/h) airflow and 85 Pa static pressure at 3300 RPM.
- Integrated Thermal Protection: Features an internal thermal overload protector to safeguard the single-phase motor against overtemperature and lockup.
- Maintenance-Free Bearings: Heavy-duty dual ball bearing system enables universal mounting orientation and reliable continuous S1 duty.
- Standard Blade Termination: Equipped with 2.8 x 0.5 mm flat terminals for rapid wiring and seamless field replacement.
