Air System

Compressed air on ships is used for different purposes. High-pressure air of 30 bar is mainly used for the main engine starting. This high-pressure air is reduced to lower working pressures through pressure reduction valves and is used for other important purposes. One of the branches of this 7-8 bar compressed air is used as control air. The control air is a filtered branch of the service air which is made free of any moisture and oil carry-over. This controlled air is used for pneumatic controllers and is important for the operation of Marrine engine controls.
