Constant CFM Performance
This WhisperGreen model features built-in intelligence called SmartFlow 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 WhisperGreen 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.
Quiet Motor Means Quiet Operation
Panasonic is the first ventilation fan manufacturer to incorporate a DC motor in residential mechanical ventilation fans. The WhisperGreen 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 Star® Qualified for Energy Savings
