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 sizing because the specifiers no longer has to worry as much about compromising the fan's performance.
Variable Speed Control
This fan is quipped with a CustomVent™ Variable Speed Control. This allows the fan to run continuously at a pre-set lower level of 0, 50-110 CFM that can be elevated to a maxium of 130 CFM when the switch is turned on. A High/Low delay timer (adjustable up to 60 minutes), will then return the fan to the mimimum CFM level after a period of time set by the user.
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 an (more...)
