Practice has proved that dry air is necessary for all industrial production. Such as spraying, pneumatic equipment, instrument control, chemical industry, food, medicine and other general factories need common compressed air; Because compressed air contains a lot of moisture, oil and dust particles, if it is not effectively removed, it will directly affect your product quality, directly affect the economic benefits of the enterprise, increase the production cost, and finally cause equipment damage and huge maintenance costs. The dust particles and oil-water droplets in compressed air can be removed by high-efficiency filter; However, if the gas cannot be filtered out, it will mix with the compressed air and flow to the downstream of the compressed air system
