EC Ø 190 mm Backward-Curved Centrifugal Fan
The EC Ø 190 mm Backward-Curved Centrifugal Fan is a high-efficiency motorized impeller engineered for compact ventilation, precision cooling, and HVAC equipment requiring superior energy performance and precise speed modulation. Combining electronically commutated (EC) brushless motor technology with an aerodynamically optimized backward-curved impeller, it delivers elevated static pressure with minimal acoustic and electrical footprint.
With integrated drive electronics supporting 0-10V and PWM continuous modulation, the unit dynamically matches airflow output to instantaneous cooling or ventilation demand. Its compact envelope, dynamically balanced rotating mass, and maintenance-free ball bearing arrangement provide dependable, continuous operation across industrial and commercial equipment enclosures.
