D3G146-LV05-31 ebmpapst 230V 146mm EC Centrifugal Fan

Description

The ebmpapst D3G146-LV05-31 is a high-efficiency 200-240 V single-phase GreenTech EC dual-inlet centrifugal fan featuring a 146 mm forward-curved galvanized steel impeller integrated into a robust PP plastic scroll housing. Driven by the M3G055-DF motor with integrated control electronics, this unit is engineered for optimized air displacement in space-constrained environments, delivering an airflow of 745 m³/h with a power consumption of 170 W. The motor features dual-side vibration damping and cooling openings on both rotor and stator sides to ensure stable, long-term operation. Equipped with an active PFC, tachometer output, and a 0-10 VDC/PWM control interface, the D3G146-LV05-31 provides a smart, low-vibration, and energy-saving thermal management solution for precision cooling and ventilation across an ambient temperature range of -25 °C to 60 °C.
