With the rapid development of science and technology, compressed air has become the second largest power energy in the world after electricity. A set of reliable, efficient and cost-effective compressed air purification system plays an important role in maintaining the stability of the production process and ensuring the high quality of the final product.

However, the current market is flooded with a large number of compressed gas purification products without authoritative certification. These products generally expose many quality hazards, such as the filter accuracy does not meet the international ISO8573 air quality standards, poor water removal performance, and high energy consumption. The use of such inferior products will easily lead to erosion of the inner wall of the pipeline, greatly shorten the normal service life of the equipment, and even cause irreparable damage to precision instruments.
