G2E120-DD70-12 ebmpapst 230V 120mm AC Centrifugal Fan

Description

The ebmpapst G2E120-DD70-12 is a professional-grade 1~ AC single-inlet centrifugal fan powered by the M2E052-CA motor. Operating at a nominal 230 VAC (50 Hz), this unit is designed for high-static pressure applications with dimensions of 178 x 184 x 156.5 mm. It features a forward-curved multi-vane impeller made of galvanized sheet steel, housed within a robust die-cast aluminum scroll housing. At 50 Hz, it achieves a rated speed of 2000 RPM with a power consumption of 62 W and a low current draw of 0.28 A. The motor is mounted on a specialized support plate for one-sided vibration damping, ensuring quiet and stable operation. Rated with Class B insulation and H0+ environmental protection, the G2E120-DD70-12 utilizes a 2 µF capacitor and includes an internally connected thermal overload protector for mission-critical reliability in S1 continuous duty cycles.
