R3G355-RB03-10 ebmpapst 230VAC 355mm EC Centrifugal Fan

Description

The ebmpapst R3G355-RB03-10 is a high-efficiency 230 V single-phase GreenTech EC centrifugal fan featuring a 355 mm backward-curved RadiCal impeller. Driven by the compact M3G074-DF external rotor motor with integrated electronics, this unit delivers an optimized airflow of 2105 m³/h while maintaining an exceptionally high static efficiency grade of N 82.5. The impeller is constructed from durable PP plastic, designed for quiet and energy-saving air displacement in a variety of ventilation scenarios. Featuring a “plug-and-play” electrical hookup and advanced motor protection including soft start and power limiting, the R3G355-RB03-10 offers a reliable, low-maintenance thermal management solution for industrial and commercial HVAC systems across an ambient temperature range of -25 °C to 50 °C.
