Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a pneumatic scraper self-cleaning filter. Background Art

[0002] A self-cleaning filter is a kind of filter that uses a columnar filter element on the inner wall of the barrel to intercept impurities in the water to remove suspended matter and particulate matter in the water, reduce turbidity, and purify the water quality.
