Description
The ebm-papst W2E143-AB09-01 (also known as W2E143AB0901) is an industrial-grade compact AC axial fan powered by an integrated M2E052-BF single-phase external rotor motor, housed in a robust 172 mm × 51 mm (6.77 in × 2.01 in) round die-cast aluminum wall ring frame. Operating on 230 VAC at 50/60 Hz, it delivers nominal speeds of 2800 RPM to 3300 RPM with air deliveries up to 290 CFM (490 m³/h) and static pressures up to 0.34 in H₂O (85 Pa) while consuming just 24 W to 30 W. Designed for rigorous continuous duty (S1), the unit combines a rugged 5-blade sheet steel impeller with dual precision ball bearings and an internally connected thermal overload protector (TOP). Electrical connection is facilitated via standard 2.8 mm × 0.5 mm flat quick-connect terminal lugs, making it an exceptional thermal management solution for mission-critical enclosures.
Key Features
- Heavy-Duty Construction: Built with a rugged die-cast aluminum housing and black-coated 5-blade sheet steel impeller for exceptional durability.
- Dual-Frequency Operation: Supports both 50 Hz and 60 Hz line frequencies delivering airflow rates up to 290 CFM.
- Internal TOP Protection: Integrated thermal overload protector safeguards motor windings against elevated operating temperatures and locked-rotor conditions.
- Maintenance-Free Bearings: Sealed precision dual ball bearings provide smooth, long-term continuous S1 duty across any mounting orientation.
- Standard Terminal Hookup: Equipped with dual 2.8 mm x 0.5 mm flat blade quick-connect terminals for simplified cabinet integration.
