The Dazhang Program introduces an innovative enhancement to the standard filter press with its automatic high-pressure water washing system. This feature is meticulously designed to elevate the performance of cleaning press cloth, ensuring unmatched efficiency and productivity.
When filter cloth encounters blockages, our cutting-edge cloth washing system utilizes high-pressure water to effectively eliminate solid obstructions. This not only accelerates filtering speed but also significantly extends the lifespan of the machine. The system is available in two distinguished types: the Single Pole Washing System and the Double Poles Washing System.
Engineered to withstand pressures up to 6mpa, our device comes in a range of configurations: the single pole washing system, the double poles washing system, and an advanced Scroll scrubbing system. Each type is designed to meet specific filtration needs, providing versatility and reliability.
