The WhisperGreen™ FV-08VKM1 with DC motor and built-in controls 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.
