With its small size and low power draw this unit is perfect for a cuddy cab or pilot house. With the help of a 12v inverter this unit will run for hours on a properly sized battery bank or solar system. This unit features a variable speed fan with 120 degrees of rotation for maximum compatibility. Its low profile design makes it ideal for installing under a bunk or other tight spaces. Our newly designed stainless steel drain pan has two drain locations to choose from and handles for easy carrying and handling during installation
