The ship’s compressed air system provides compressed air for generators, main engine start-up and submarine door debris removal, and other places on-board that need compressed air.
The main uses of compressed air in marine applications:
1. Starting the engine
Compressed air is used on ocean-going ships as a powerful and storable energy source for starting large diesel engines. Although air is used at a lower pressure (<150psi), it is usually stored at a higher pressure for compact storage to allow enough volume for multiple start-up attempts.
2. Control and instrument air
There are many systems and processes on board that require compressed air. Engine emission monitoring systems, throttle controls, control valves and tool air are just a few of the many uses and applications of compressed air on-board.
3. Inert gas (Nitrogen)
Ships that use liquefied natural gas (LNG) as a fuel source or transport LNG need to cover their fuel tanks with nitrogen to prevent the possibility of explosion. Instead of bringing nitrogen tanks on board, it makes more sense to generate nitrogen on site.
When untreated compressed gas is used directly, it may cause malfunctions, this is particularly risky in the marine offshore industry, where Health, Safety & Environment (HSE) are top priority. Therefore, it is critical to maintain the compressed air treatment system of a ship’s pneumatic system.

The core functions of compressed air system in railway include trains breaks systems, suspensions, doors and various other equipment. AFE offers a variety of reliable solutions for trouble-free operations.
In many semiconductor and electronics industries, compressed air is often used in sensitive high-tech equipment to process and manufacture electronic components. Contamination of compressed air can lead to costly complications.
As an important energy source for industrial products, compressed air has a wide range of applications in various manufacturing industries and is known today as the "Fourth Utility" in the manufacturing industry.
In the chemical industry, toxic, corrosive and unstable gases are common parts of the production process, making the requirements for compressed air quality strict. This is vital to maintain product purity, to ensure customers the highest quality chemicals.
