Constant CFM Performance
This WhisperGreenT model features built-in intelligence called SmartFlowT Optimum CFM Technology. This unique "electronic-brain" lets the fan do what was once thought to be impossible: perform at a constant CFM regardless of elbows and other factors that might hinder performance. Basically, when a WhisperGreenT fan faces static pressure, its speed is automatically increased to ensure that the desired CFM is actually achieved. This allows the fan to perform as rated and makes for easier installation because the installer no longer has to worry as much about compromising the fan's performance.

DC Brushless Motor
Panasonic's DC brushless motor provides unparalleled energy efficiency with its magnetic rotor and print circuit board. The magnetic rotor prevents energy loss while the print circuit board incorporates a unique IC chip which monitors and directs the RPM of the fan blade. The combination of these two unique features allows the DC motor to have higher energy efficiency than an AC motor.

Quiet Motor Means Quiet Operation

Panasonic is the first ventilation fan manufacturer to incorporate a DC motor in residential mechanical ventilation fans. The WhisperGreenT series incorporates a totally enclosed DC motor designed for extremely quiet, energy-efficient operation. The permanently lubricated motor is also engineered for trouble-free, continuous run for several years.
ENERGY STARŪ-Qualified for Energy Savings
ENERGY STARŪ-qualified products feature super-quiet operation and high CFM-to-Watt efficiency. The ENERGY STAR program was created to help consumers identify products that can save them money and protect the environment by saving energy. As an ENERGY STAR partner, all of our fans are ENERGY STAR-qualified and labeled accordingly.
