Clean and Dust
The powerful spray of compressed air can remove dust, particles, and other dirt on the surface of the parts, go deep into the gap to remove inaccessible dust, and will not wear or scratch the surface of the parts, especially for objects that cannot be cleaned with solvents or be touched. Usually pneumatic tools, such as Air blowing gun will be used.
Removal and installation
Using screws and nuts for installation, disassembly, and assembly of parts, drilling tools and so on, all need to be executed by compressed air, often used together with pneumatic tools, such as pneumatic wrenches, pneumatic drivers, etc.
Lifting and Handlings
Used for lifting -- compressed air drives the lifting equipment such as cranes or pneumatic lifting equipment.
