Industrial centrifugal fan for HVAC systems
The Fans R3G310-AN43-71 is a motorised impeller built for industrial cooling and air-intake duties. It runs on 230 V AC across a 200–277 V range at 50/60 Hz. The unit suits engineers specifying ventilation in commercial or industrial plant rooms.
Thermals noise and power at 47 W draw
Rated power consumption is 47 W with a current draw of 3.0 A. The motor operates continuously between -25 °C and 45 °C ambient temperature. An IP54 enclosure protects the internals from dust ingress and water splashes in harsh environments.
Backward curved blades remove need for scroll
The backward-curved impeller design allows direct air intake without a separate scroll casing, simplifying installation. Speed is adjustable from 0 to 100 % via analogue or serial interface. The package includes the matched motor and impeller assembly for plug-and-play commissioning.

Questions about this item
How is the R3G310-AN43-71 centrifugal fan mounted, and what step is often missed?
The 318 mm diameter impeller fits directly into the duct or housing without a separate scroll; the step often missed is verifying the 119.5 mm motor depth clears the rear panel before tightening the flange.
What maintenance or replacement will the ebm-papst motorised impeller need over time?
The sealed IP54 motor bearings are lubricated for life; plan only periodic cleaning of the backward-curved blades to maintain the 35000 m³/h airflow capacity.
At what ambient temperature does the fan hit its thermal limit during continuous operation?
The maximum rated ambient temperature is 45 °C; sustained operation above this trips the internal thermal protection and reduces the 47 W power draw.
