Description
The ebm-papst W4E400-CP14-71 (also known as W4E400CP1471) is an industrial AC axial fan assembly engineered with an integrated M4E074-EI external rotor motor, a 400 mm (15.75 in) 5-blade steel impeller, and a robust Ø 528 mm (20.79 in) coated wall ring housing. Powered by a single-phase 115 VAC 60 Hz supply, it delivers up to 2910 CFM (4944 m³/h) of airflow at 1680 RPM with a nominal input power draw of 270 W to 280 W. Mechanical construction features heavy-gauge galvanized sheet steel coated in black RAL 9005 plastic, dual maintenance-free ball bearings, and an integrated steel guard grille. Internal protection includes an automatically resetting thermal overload protector (TOP) and IP44 moisture sealing rated for continuous S1 industrial duty.
Key Features
- High-Flow Aerodynamic Profile: Five aerodynamically curved sheet steel blades deliver up to 2910 CFM for demanding ventilation and heat rejection.
- Rugged Wall Ring Assembly: Galvanized sheet steel ring coated with RAL 9005 black plastic provides high-rigidity structural panel mounting.
- Integrated Motor Protection: Internally wired thermal overload protector automatically safeguards motor windings against phase faults and high-temperature overloads.
- Heavy-Duty Ball Bearings: Dual sealed maintenance-free ball bearings ensure 40,000 hours of continuous S1 operation in any horizontal orientation.
- Comprehensive OEM Compliance: Certified to UL 1004-3, CSA C22.2 No. 77, and CE standards for reliable industrial panel integration.
