R3G355-AM14-61 ebmpapst M3G084-FA FFU purification fan

Description

The ebmpapst R3G355-AM14-61 is a highly efficient 355 mm EC Centrifugal Fan (Backward Curved, Single Inlet) designed for single-phase operation. It operates on a nominal voltage of 230 VAC with a voltage range of 200 VAC to 277 VAC at 50/60 Hz. The fan achieves a speed of 1900 RPM, consuming 350 W of power with a current draw of 1.5 A. At its free air point, the fan delivers a maximum air flow of 3500 m³/h, and its maximum static pressure is 550 Pa (2.21 inAq). This fan features an IP20 protection rating, active Power Factor Correction (PFC), and an integrated PID controller for intelligent speed regulation, making it ideal for ventilation units and air handling systems that require high air volume and precise control.
