R3G190-RC05-03 ebmpapst

Description

The ebmpapst R3G190-RC05-03 is a highly efficient 230 VAC EC centrifugal fan from the RadiCal® series, engineered for advanced industrial and commercial thermal management. Integrating ebmpapst’s state-of-the-art GreenTech EC motor technology (M3G055-BI), this backward-curved, single-inlet fan delivers a powerful maximum air flow of up to 735 m³/h at free air, while maintaining a nominal power consumption of just 83 W. Housed in a die-cast aluminum electronics casing with an aerodynamically optimized 7-blade PA plastic impeller, the unit weighs 1.1 kg and features an overall size footprint of 190 mm. Equipped with maintenance-free ball bearings and an IP54 protection rating, it operates reliably across an ambient temperature range of -25 °C to +60 °C. Boasting intelligent control inputs (0-10 VDC / PWM), a tachometer output, and built-in electrical safeguards, the R3G190-RC05-03 provides a superior, precision-controlled cooling solution for sophisticated enclosures and automation systems.
