Description
The ebm-papst W6D910-GB01-01 (also known as W6D910GB0101) is an industrial high-capacity three-phase AC axial fan engineered with an integrated M6D138-NA external rotor motor and a heavy-duty square full nozzle measuring 1070 mm (42.13 in) in outer flange width. Operating on 400 VAC at 50 Hz with dual Delta/Star (Δ/Y) wiring capabilities, it delivers up to 28,260 m³/h (16,633 CFM) of airflow and reaches up to 160 Pa (0.642 in H₂O) maximum back pressure at 920 RPM with a 2020 W rated power draw. Aerodynamic propulsion is driven by a 5-blade HyBlade structure featuring sheet aluminum inserts overmolded with PP plastic, paired with an IP54-rated cast aluminum rotor and pre-galvanized coated sheet steel housing. The fan integrates an internal thermal overload protector (TOP) with basic insulation and terminal box connectivity, supporting reliable continuous S1 duty across an ambient envelope of -40 °C to +60 °C.
Key Features
- Aerodynamic HyBlade Impeller: Five sickle-shaped composite blades with sheet aluminum inserts overmolded in polypropylene ensure high efficiency and low noise.
- Dual-Speed Δ/Y Operation: Dual Delta and Star winding connections provide flexible airflow outputs of 28,260 m³/h and 25,660 m³/h.
- Rugged Square Nozzle Housing: Pre-galvanized sheet steel frame with black plastic coating provides rigid structural mounting and optimized inlet flow geometry.
- Thermal Overload Protection: Built-in TOP thermal contacts provide continuous winding temperature monitoring to protect the M6D138-NA motor from thermal runaway.
- Industrial Ingress & Corrosion Defense: Sealed to IP54 standards with F3-1 environmental protection class, rotor/stator condensation drainage, and robust Class F insulation.
- ErP 2015 Efficiency Compliance: Surpasses European eco-design regulations with an overall static efficiency rating of 38.4% and an efficiency grade of N42.9.
