™
Technology that surpasses all other range hoods in performance,
sound and energy use. Never before has there been a blower system
built to embody quiet flow design, intelligent operation, and digital
motor technology in one package—delivering superior sound, power
and energy efficiency.
2X Quieter Operation
Three innovations make the quiet operation of
the BEST iQ Blower system possible.
• A smooth interior blower housing reduces turbulence.
• Improved blower wheel design delivers greater airflow at lower RPMs.
• A balanced, digital DC motor minimizes vibration.
0.5 sones is like a quiet whisper (low speed).

Competitors models can lose up to 30% of their
stated CFM in a normal duct run.
1. When the installation is complete, the installer touches the
calibration button to activate the GPS technology.
2. GPS tells the control board to run the motor at different speeds
3. In the event of a severe restriction the calibration button will
