Which type of air is used for elevators and auto starting diesel generators?

The correct answer pertains to High Pressure Air. High pressure air is specifically utilized for critical operations such as elevating the lift of elevators and for the auto-starting of diesel generators. The use of high pressure air in these applications ensures that the necessary force is available to initiate movement or engine operation effectively and efficiently.

Control Air, Ship Service Air, and Compressed Air serve distinct purposes in a marine environment. Control Air is typically used for system controls and regulation, ensuring safe operation of various machinery and systems. Ship Service Air serves broader purposes such as supplying air for tools and other ancillary systems aboard the ship, while compressed air generally refers to any air that has been compressed for various uses, not specifically tied to the critical functions of elevators or generator starts. Thus, high pressure air stands out as the most suitable choice for these specific applications.
