Thanks to an aerodynamically modified housing with improved strut design, the operating noise has been reduced by approximately 4 dB(A) compared to the 3300 series. Combining the aerodynamic design with a 35.10 motor has increased efficiency from 14% to 21%.
This fan series fully reflects our GreenTech® philosophy, providing even better economic and ecological performance with reduced power consumption.
