D2D146-BG03-16 ebmpapst 400V/480V 146mm AC Centrifugal fan

Description

The ebmpapst D2D146-BG03-16 is a high-performance 3~ AC dual-inlet centrifugal blower powered by the heavy-duty M2D068-GA motor. Designed for global industrial grids, it operates across a wide nominal voltage range of 400V to 480V (380-480 VAC) with a Star (Y) wiring configuration. This unit features dual 146 mm forward-curved impellers made of black-painted sheet steel, housed in a robust galvanized sheet steel casing with a RAL 9006 white-aluminum coated guard grille. At 60Hz/480V, it reaches a peak speed of 2960 RPM with a power consumption of 560 W and a current draw of 0.76 A. Engineered for extreme reliability, it carries an IP55 protection rating and Class F insulation, making it ideal for S1 continuous operation in high-static pressure environments like industrial HVAC, cabinet cooling, and power electronics ventilation.

Application
The ebmpapst D2D146-BG03-16 3-phase blower is an industrial thermal management solution designed for high-density electrical enclosures, frequency inverters, and HVAC air handling units. Its dual-inlet centrifugal design is optimized to provide high-velocity airflow even when facing significant back pressure (up to 385 Pa). The IP55 rating ensures the motor is protected against dust and water jets, making it suitable for harsh industrial factory floors. With multi-voltage support (400V-480V) and robust sheet steel construction, this blower provides 24/7 maintenance-free performance for mission-critical cooling in power conversion systems, medical equipment, and large-scale telecommunications infrastructure.
