Industrial blower for HVAC systems
The Fans K3G560-RB31-71/F03 is a 560 mm centrifugal blower built for industrial HVAC installations. It uses an external rotor motor integrated into the impeller for compact dimensions and forced electronic cooling. The unit suits engineers specifying airflow equipment for air-handling units or ventilation plants.
Three-phase 400 VAC supply with 50/60 Hz operation
The motor requires a three-phase supply rated at 400 VAC and tolerates a range from 380 to 480 VAC at 50 or 60 Hz. It draws 4.43 A at full load and consumes 2900 W. Speed is fixed at 1650 rpm and the controller accepts 0–100 % speed control via an analog or serial interface.
Ambient temperature range from -25 °C to 55 °C
This blower is rated for continuous operation between -25 °C and 55 °C ambient. Installations outside that window will exceed the motor’s thermal limits. Buyers who need operation beyond 55 °C or below -25 °C must select a different model.

Questions about this item
Should I choose the 380 VAC or 480 VAC end of the voltage range for my supply?
The fan accepts a nominal range of 380 to 480 VAC three-phase, so any supply within that window will work; 400 VAC is the rated nominal voltage.
What airflow can I expect once this 560 mm blower is installed in a duct system?
The impeller is rated for up to 35000 m³/h free air; actual delivered flow will depend on duct static pressure and any inlet or outlet restrictions.
How does the analog or serial speed-control interface limit the motor in practice?
The interface provides 100 % speed control from zero to the rated 1650 rpm, letting you match airflow to demand without exceeding the 2900 W power rating.
