Description

Technical Field

[0001] The utility model relates to the technical field of air source filtering, in particular to an air source filtering device. Background Art

[0002] With the development of science and technology, various industries are developing better and better. However, in the production process of many industries, gas sources carrying impurities will be generated. Gas sources carrying impurities cannot be discharged directly, and thus need to be filtered through gas source filtration devices.
