- EC motor runs on 230 V single-phase supply at 50/60 Hz
- Speed controllable 0–100 % via analog or serial interface
- Operates reliably from -25 °C to +45 °C ambient
- External rotor design gives compact, forced-cooled construction
Compact EC centrifugal blower
The Fans R3G250-AK41-71 is a GreenTech EC centrifugal blower driven by an M3G084-DF external-rotor motor. It runs on single-phase 230 VAC across a 200 to 277 V range at 50 or 60 Hz, drawing 3.1 A and 490 W at a fixed speed of 3390 rpm. The backward-curved impeller operates without a scroll housing for a compact footprint.
Installers needing 100 % speed control
This unit suits HVAC technicians and system integrators who require 0 to 100 % speed control via analog or serial interface and plug-and-play commissioning. It is not for buyers who need a forward-curved blower with an integrated scroll housing, nor for applications where the ambient temperature exceeds 45 °C or drops below -25 °C.
3390 rpm fixed-speed rating
The decisive specification is the 3390 rpm operating speed combined with 490 W power consumption and 3.1 A current draw at 230 V. These figures determine whether the blower matches the airflow and electrical load calculated for the target ventilation system.

Questions about this item
How can I confirm the blower is running at the intended 3390 rpm after installation?
Measure the current draw at the 230 V supply; it should read 3.1 A and power consumption 490 W when the unit reaches 3390 rpm.
What comes in the box with the R3G250-AK41-71 and what must be sourced separately?
The box contains the centrifugal blower with integrated EC motor; mounting hardware, ducting, wiring and any speed-control interface are not included.
Which voltage-range version should I choose for a 230 V single-phase supply?
Select the 200–277 VAC nominal range model; it covers 230 V at 50/60 Hz and is rated for ambient temperatures from -25 °C to 45 °C.
