Industrial EC centrifugal blower
The Fans R3G630-RA38-76 is a 400V EC centrifugal blower built for industrial HVAC systems that demand controllable, high-volume airflow. Its external-rotor motor sits inside the impeller for compact installation and direct motor cooling. Speed is adjustable from 0 to 100% via analog or serial interface, simplifying integration into building-management or process-control networks. The unit arrives new and ready for duct-mounted or free-wheeling deployment.
Replaces fixed-speed AC blowers
Fixed-speed AC blowers run at a single operating point and waste energy when demand drops. This EC model delivers 1240-1300 rpm across a 380-480 VAC range while drawing 3.8 A at 2500 W, so the upgrade pays back where variable air volume is required. The jump is worth it when the system needs continuous speed modulation, lower inrush current, or simpler commissioning with matched open-loop controls. It is not for installations that must stay on legacy AC voltage taps without a controller.
Airflow capacity and thermal limits
The impeller moves up to 35000 m3/h in a sturdy steel housing rated for -25 to 40 °C ambient. At 2500 W the motor reaches its thermal ceiling, so sustained operation above rated power or in ambients above 40 °C will trip protection. The design handles ducted supply or exhaust duties with full speed headroom down to minimum flow, but it cannot serve applications needing higher static pressure than the backward-curved blade geometry provides.
