A4D630-AD01-01 ebmpapst 400V 630mm 2630W AC Axial Fan

Description

The ebmpapst A4D630-AD01-01 is a high-performance 3~ AC Axial Fan featuring a 630 mm diameter and a 5-blade HyBlade® design, powered by a high-torque M4D138-LA external rotor motor. Designed for 400 VAC (50 Hz) operation, this unit supports both Delta (Δ) and Star (Y) connections, offering dual-speed flexibility with a maximum speed of 1320 RPM and a powerful 2630 W power input. The fan is built for extreme durability, utilizing aluminum sheet inserts sprayed with PP plastic for its blades and a black ABS plastic terminal box. Engineered for S1 continuous duty with Class F insulation and IP54 protection, it operates reliably in ambient temperatures from -40 °C to 60 °C. Equipped with a Thermal Overload Protector (TOP) and featuring condensate discharge holes on both rotor and stator sides, the A4D630-AD01-01 is a mission-critical thermal management solution for heavy-duty industrial condensers, large heat exchangers, and high-capacity cooling systems.

[Application]
The ebmpapst A4D630-AD01-01 is engineered for heavy-duty industrial cooling where massive air volume and high static pressure (up to 220 Pa) are required. Its 630 mm HyBlade® design is optimized for large-scale refrigeration condensers, air-cooled heat exchangers, and cooling towers. The dual Δ/Y connection capability allows operators to toggle between high-performance heat extraction and more energy-efficient or quieter operation, while the robust aluminum-plastic composite blades and dual-side condensate drainage ensure maximum reliability in harsh outdoor or high-humidity industrial environments.
