The WhisperGreen line of ventilating fans employs state of the art technology providing a number of
unique features that lead to improved indoor air quality. These features need to be fully understood
prior to installation to full realize the benefits fans offer.
Spot and Continuous Ventilation: These fans are designed to run continuously ensuring a healthy
environment at low CFM levels 24 hours a day. By utilizing CustomVent Variable Speed Control
the fans are built to run continuously at a pre-set lower level (FV-13VKM3 and FV-13VKS3:0,50,70,90,
110 CFM ; FV-08VKM3 and FV-08VKS3:0,30,40,50,60,70 CFM). The setting is dependent on the size of
the room and the individual wishes of the homeowner. It is crucial that the installer pre-set the lower
setting during the installation. Please refer to the chart below and page 5 of the installation instructions.

These fans are also built to take care of the homeowner's spot ventilation needs when the room is
occupied. This models kick-up to a maximum level of 130 CFM for the FV-13VKM3 and FV-13VKS3
and 80CFM for the FV-08VKM3 and FV-08VKS3 either when the switch is turned on (available with
FV-13VKS3 and FV-08VKS3) or activated by the SmartAction Motion Sensor (available with
FV-13VKM3 and FV-08VKM3).
A High / Low Delay Timer, located inside the fan unit, is utilized to return the fan back to the pre-set
Continuous ventilation mode. The installer needs to consult with the homeowner for the desired
setting on the timer (0.5 - 60 minutes) and make the adjustments during the installation.
Optimum Ventilation Performance: Generally duct length, elbows and other factors increase static
pressure hindering the performance of most ventilation fans. This fan utilize SmartFlow microchip
technology that monitors the static pressure in the system and speeds up or slows down the rpm of the
fan depending on the amount of resistance. This allows the fan to perform as rated, whether facing
0.1,0.2 or even 0.25 inches water gauge. The bottom line is that it makes for easier installation.
The installer no longer has to worry about compromising the fan's performance.
Outstanding Energy Savings: These fans are the very first to be built using DC motor technology.
The new DC motor is 30% - 70% more energy efficient than the minimum ENERGY STAR requirements.
