Experience the advanced functionality of our Once Open Filter Press, ingeniously designed with an extended cylinder and beam. It utilizes a state-of-the-art S.S. chain or slide mechanism to synchronously connect each filter plate, ensuring simultaneous opening while the pressing plate retracts. Integrated with a cutting-edge vibration device, this system facilitates rapid unloading and automatic discharge of materials, epitomizing efficiency and convenience.
Advantages: Experience unparalleled efficiency and significant labor savings with our innovative filter press technology.
Disadvantages: Best suited for operations with a smaller range of filtering plates, where using up to 30 plates is ideal for optimal performance.
