Industrial Centrifugal Fan 400V AC
The Fans R3G280-AU11-C1 is a three-phase industrial centrifugal fan built for rail transportation and photovoltaic installations. It runs on a nominal 400 VAC supply across a 380 to 480 VAC range at 50/60 Hz. The external-rotor motor M3G084-GF reaches 3100 rpm while drawing 1.6 A and consuming 1000 W.
Compact External-Rotor Design
The motor sits inside the impeller, giving a compact footprint and forced electronic cooling without a separate scroll housing. Speed is fully controllable from zero to maximum via analog or serial interface, allowing simple open-loop start-up with matched components. The steel-plate construction suits harsh environments and supports plug-and-play integration.
Sustained Operation from -25 °C to 60 °C
Rated for continuous ambient temperatures between -25 °C and 60 °C, the fan delivers up to 35000 m³/h airflow under steady load. The external-rotor layout keeps motor temperatures stable during prolonged duty cycles. Not suited for builds requiring lower voltage supplies, variable-frequency drives outside the stated range, or installations that cannot accommodate three-phase 400 VAC power.
