WhisperGreen® 80 CFM Ceiling Mounted Ventilation Fan with DC Motor and Variable Speed ControlsConstant 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 sizing because the specifiers no longer has to worry as much about compromising the fan's performance.Variable Speed Control
This fan is equipped with a CustomVent™ Variable Speed Control. This allows the fan to run continuously at a pre-set lower level of 0, 30-70 CFM that can then be elevated to a maximum of 80 CFM when the switch is turned on. A High/Low delay timer (adjustable up to 60 minutes), will then return the fan to the minimum CFM level after a period of time set by the user.Delay Timer
A High/Low delay timer (adjustable from 30 seconds - 60 minutes), will then return the fan to the minimum CFM level after a period of time set by the user.
