G4D310-DK03-05 ebmpapst 400V 310mm AC Centrifugal Fan

Description

The ebmpapst G4D310-DK03-05 is a heavy-duty 3-phase AC Centrifugal Fan designed for high-static pressure industrial applications. Operating at a nominal 400 VAC (50 Hz), this high-power unit is driven by a specialized external rotor motor, drawing 3.9 A with a substantial power consumption of 2180 W. It features a 310 mm diameter backward-curved (or high-capacity forward-curved) impeller, optimized for delivering maximum airflow in systems with high internal resistance. Rated at a speed of 1310 RPM and protected to IP54 standards, this fan is engineered for durability in dusty or moist environments. The G4D310-DK03-05 provides a robust thermal management solution for large-scale power electronics, industrial HVAC systems, and high-density server room cooling where 24/7 mission-critical reliability is required.
