Product Review

Panasonic WhisperGreen 80 CFM Premium Ceiling Mounted Continuous and Spot Ventilation Fan Combination with DC Motor and Ligh - FV-08VKSL2Constant CFM PerformanceThis 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 installation because the installer no longer has to worry as much about compromising the fan's performance.Variable Speed ControlThis fan is equipped with a CustomVent™ Variable Speed Control. This allows the fan to run continuously at a pre-set lower level of 30-70 CFMs that can then be elevated to a maximum of 80 CFMs when the switch is turned on for intermittent ventilation. In fact, it is quiet enough that you might not even know it's on.
