WhisperGreen Ventilation Fan

The Panasonic Home and Environment Company's WhisperGreen ventilation fan combines energy efficiency and quiet operation. The WhisperGreen series also incorporates DC motors and built-in controls to regulate performance. These ceiling-mounted ventilation fans offer 75 to 400 percent more energy efficiency than the minimum ENERGY STAR requirements, the company says. The custom variable speed control allows the fan to run continuously at 30 to 80 cfm (cubic feet/minute), and 80 cfm when switched on or activated by an integrated motion sensor in some models. Its delay feature, which keeps the fan running at 80 cfm after a person leaves the bathroom, allows for moisture and odors to be effectively evacuated.
