Application scope
The Fans R3G310-AN48-78 is a 230 VAC centrifugal blower built for industrial HVAC and ventilation systems. It suits installers who need a backward-curved impeller that delivers up to 35000 m³/h without a separate scroll housing. The unit operates on single-phase mains at 50 or 60 Hz and is rated for ambient temperatures from -25 °C to 50 °C.
Installation notes
The blower uses an external-rotor motor with integrated electronics, so wiring is limited to the mains supply and an optional 0-10 V or serial speed-control signal. No separate driver board is required, but the 3.0 A current draw at 470 W demands appropriately rated cable and over-current protection. Verify that the mounting arrangement can handle the reaction torque of the metal impeller at 2400 min⁻¹.
Decisive specification
The nameplate voltage range of 200 to 277 VAC is the single figure that determines compatibility; the blower will not start reliably outside this window. If your supply is fixed at 230 VAC ±10 % the unit matches directly, otherwise a different voltage variant must be sourced.

Questions about this item
How can I verify the blower is running correctly after installation?
Confirm the motor reaches 2400 rpm, draws about 3.0 A at 230 VAC, and operates within the -25 °C to 50 °C ambient range.
What comes in the box and what must I source separately?
The package contains the R3G310-AN48-78 centrifugal blower with metal impeller; mounting hardware, ducting, speed-control wiring and any required filters are not included.
Which voltage and speed variant should I select for a 230 VAC supply?
Choose the 230 VAC, 2400 rpm version (model R3G310-AN48-78) rated for 470 W and 3.0 A, compatible with 50/60 Hz and a 200–277 VAC range.
