1-27 What are the hazards of impurities in compressed air?

Compressed air from the compressor contains solids, water, and oil, which can corrode equipment, deteriorate materials, cause valve failures, and wear moving parts. Water condensation can also cause system failures, especially in cold climates.
Case Details
Answer: The compressed air output from the air compressor contains a large amount of harmful impurities, the main impurities are solid particles, water and oil in the air.
The vaporized lubricating oil will form an organic acid to corrode the equipment, causing rubber, plastic and sealing materials to deteriorate, blocking small holes, causing valve failure and contaminating the product.
The saturated water in the compressed air will condense into water under certain conditions and gather in some parts of the system. This water has a corrosive effect on components and pipes, causing moving parts to get stuck or wear, causing pneumatic components to fail and leak; in cold areas, water freezing will cause pipes to freeze or crack.
Impurities such as dust in compressed air will wear the relative moving surfaces in cylinders, pneumatic motors and pneumatic reversing valves, reducing the service life of the system.
