Self-cleaning filters are used in industrial liquid filtration systems where continuous removal of suspended solids is required without disposable filter cartridges or filter bags. These filtration systems use wedge wire filter elements combined with scraper cleaning mechanisms to maintain stable operation during filtration.
Industrial self-cleaning filtration systems are commonly used in water treatment, coatings, chemicals, oils and process liquids where reliable particle removal and minimal maintenance downtime are essential.

Self-cleaning filtration – technical overview
Self-cleaning filters are industrial filtration systems designed for continuous removal of suspended solids from liquids without the need for disposable filter elements. These systems typically use stainless steel wedge wire filter elements combined with mechanical scraper cleaning mechanisms to maintain filtration performance during operation.
In industrial filtration systems the filter element captures suspended particles on the external surface of the screen while a rotating scraper removes accumulated solids. The particles are transported to a sediment chamber and discharged through a drain valve without interrupting the filtration process.
Operating principle
Self-cleaning wedge wire filters operate using a cylindrical filter element with precision slots that retain particles while allowing the process liquid to pass through. During operation the filter element rotates while a scraper blade removes solids from the screen surface. These particles settle in the lower chamber of the filter housing and are periodically discharged using system pressure.
