Optimum ventilation performance:
Duct length, elbows and other factors increase static pressure which can hinder the performance of most
ventilation fans. This fan utilizes Smart Flow microchip technology that monitors the static pressure in the
system and speeds up or slows down the RPM of the fan depending upon the amount of resistance within the
ducts. This feature allows the fan to perform as rated and avoid potential installation issues.
Outstanding Energy Savings:
The WhisperGreen Select line of fans are built using DC motor technology. The DC motor is 30% - 70% more
energy efficient than the minimum ENERGY STAR requirements.
