Introducing the Dazhang Program: a cutting-edge, automatic high-pressure water washing filter press. This innovative system enhances the capabilities of the standard model by incorporating a sophisticated high-pressure washing system, specifically designed to clean press cloth efficiently.
When the filter cloth becomes obstructed, our advanced cloth washing system utilizes high-pressure water jets to effectively clear away the solid blockage. This process not only accelerates the filtering speed but also significantly extends the lifespan of the equipment. Our offerings include two sophisticated types: the Single Pole Washing System and the Double Poles Washing System.
Engineered for excellence, this device boasts a maximum design pressure of 6mpa and is available in various models: the Single Pole Washing System, the Double Poles Washing System, and the innovative Scroll Scrubbing System.
