EC Centrifugal Blower for HVAC Applications
The Fans R3G280-RR10-P1 is a new EC centrifugal blower built for HVAC systems. It uses an external-rotor motor (M3G084-DF) that runs on 110 VDC with an input range of 77 to 138 VDC. The unit draws 4.3 A at 475 W and spins at 2600 rpm. It operates from -40 °C to 60 °C and offers 100 % speed control via analog or serial interface.
Industrial Installers Needing Compact Air Movement
This blower suits engineers and contractors who need a sturdy steel-plate housing, forced electronic cooling and plug-and-play commissioning in a compact design. It is not for buyers who require an integrated scroll housing, as the backward-curved impeller is designed as a free-wheeling fan. It also does not fit projects that demand AC-only drive architecture.
Matched Open-Loop Control and Motor Package
The bundled advantage is a perfectly matched open-loop control, motor and fan assembly that simplifies start-up. The 100 % speed-control interface and plug-and-play wiring reduce integration time, while the external-rotor layout provides direct motor cooling without extra ductwork.

Questions about this item
What DC voltage supply do I need to power the R3G280-RR10-P1 blower?
The blower runs on a nominal 110 VDC supply and will operate across a 77 VDC to 138 VDC range.
Will the blower's 2600 rpm speed and 4.3 A current draw overload my existing 110 VDC circuit?
At full load the unit draws 4.3 A and consumes 475 W, so the circuit and wiring must be rated for at least that current.
How can I verify the blower is running correctly after installation?
Confirm the fan reaches 2600 rpm, draws approximately 4.3 A at 110 VDC, and moves air within the 35000 m³/h capability while ambient temperature stays between -40 °C and 60 °C.
