Product Description
WhisperGreenTM 80 CFM Premium Ceiling Mounted Vent Fan: Home Improvement. This unique electronic-brain inch 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. This WhisperGreen(TM) model features built-in intelligence called SmartFlow(TM) Optimum CFM Technology. Basically, when a WhisperGreen(TM) fan faces static pressure, its speed is automatically increased to ensure that the desired CFM is actually achieved.
