The WhisperGreenâ„¢ Series ventilation fan line includes the premium ceiling-mounted fan Model FV-11VKS1 and Model FV-11VKM1 premium ceiling-mounted fan with Smart Actionâ„¢ motion sensor. The motion sensor automatically activates whenever someone enters or leaves the room, so there's no need to manually turn the fan on or off. The Custom Ventâ„¢ variable-speed control with delayed-off timer allows the fan to run continuously at a preset level (30 to 110 cfm). When the switch is turned on or the motion sensor is activated, the fan switches to the maximum level of operation. A delayed-off timer returns the fan to the minimum cfm level after a period of time set by the user. With the SmartFlowâ„¢ optimum cfm technology, the fan is designed to perform at a constant cfm. When a WhisperGreen fan faces static pressure, its speed is automatically increased to ensure that the desired cfm is not compromised, the company states.
