Description
The ebmpapst R3G310-AN43-71 is a high-efficiency 230 VAC EC centrifugal fan with dimensions of Ø 318 x 210 mm. Driven by an M3G084-FA motor, this unit features dual ball bearings, a die-cast aluminum electronics housing, a black-painted rotor, and a 6-blade sheet aluminum backward-curved impeller. It delivers a Working Air Flow of 1065.3 CFM (1810.0 m³/h / 30.17 m³/min) and a Static Pressure Increase of 51.70 mmH₂O (507.0 Pa / 2.04 inH₂O) at a rated speed of 2,435 RPM. Operating on a single-phase nominal voltage of 230 VAC (50/60 Hz) within an operating voltage range of 200 – 277 VAC, it features a Max. Current Draw of 3.0 A with a Max. Power Consumption of 470 W. Equipped with a 0-10 VDC / PWM control interface, 10 VDC output (max 1.1 mA), alarm relay, soft start, and line undervoltage detection, it provides IP54 protection, insulation class B, protection class I, and operates continuously (S1) within an ambient temperature range of -25 to +45 °C (storage -40 to +80 °C). Weighing 4.56 kg, it carries safety certifications including CSA, CCC, EAC, UL, CE, and RoHS.
