These large ventilators have been placed and installed on top of their respective dorade boxes. These are quite large, and look terrific as a pair. The dorade boxes were built specifically to match the exact camber of the deck while remaining level along the top surface. Unlike other ventilators on the ship, these two have a very important purpose. These provide a specific volume of air to adequately ventilate the Engine Room. The port side ventilator is designated as the intake, while the starboard side will be mated to an exhaust fan in the engine compartment to cycle the air through the space. Like everything on a ship, they are beautiful but also serve a purpose.Bookmark the permalink.
