Why do manufacturers of high-end range hoods favor this EC146 Extractor blower?
The dual-inlet centrifugal fan is the correct choice for kitchen exhaust systems because it delivers approximately 40% more airflow at the same impeller diameter and speed, generates high static pressure to overcome the resistance of grease hoods, elbows, and fire dampers, reduces noise by 8-12 dB(A) compared to traditional single-inlet fans, and, with EC motors maintaining efficiency above 85% even under partial load, achieves energy savings of up to 70% compared to traditional AC motors while supporting 0-10V/PWM stepless speed control for "on-demand ventilation" based on grease concentration.
