Self-Cleaning Filters remove retained material from the screen surface online without interrupting filtration, making them suitable for water treatment and industrial liquid systems that run continuously. This category includes the Automatic Scraper Filter, PYY/PX/PLP/PT Brush-Type Self-Cleaning Filter, and Modular Self-Cleaning Filter. Cleaning can be triggered by a differential pressure signal, a preset timer, or manual operation.
Screens are mainly 304 and 316L stainless steel, with filtration accuracy ranging from 20 μm to 5000 μm depending on the model, which covers both fine retention and coarse particle interception. These filters are used for cooling circulating water, raw water pretreatment, industrial circulating water, irrigation, paper mills, and liquid filtration in petrochemicals, oils and fats, coatings, and food and beverage. Selection requires confirming medium viscosity, impurity content, working pressure, and the available power and air supply on site.
