In the process of oil drilling, compressed air is used to drive pneumatic tools underground, such as the rotation of roller bits. Purified compressed air can ensure the normal operation of tools and reduce tool wear and failure caused by impurities.

In thermal power generation, boiler combustion requires a large amount of air to support the full combustion of fuels such as coal, natural gas, etc. Compressed air purification equipment can remove dust, moisture, and other impurities from the air. Pure air contributes to efficient combustion of fuel and improves the thermal efficiency of boilers.

In the process of ironmaking, blast furnaces require a large amount of pure air to support the combustion of coke, thereby providing heat for the reduction reaction of iron ore. Compressed air purification equipment can remove dust, moisture, and harmful gases from the air.

In the process of car body painting, compressed air is used to drive the painting equipment. Pure compressed air can ensure that paint is evenly and of high quality sprayed onto the vehicle body. If the compressed air contains impurities such as oil, water, dust, etc., it can cause defects on the painted surface, such as orange peel, pinholes, particles, etc.
