Introducing the innovative Once Open Filter Press, designed with an extended cylinder and beam. This cutting-edge system utilizes a stainless steel chain (or slide) for seamless connection of each filter plate, enabling simultaneous opening while the pressing plate withdraws. Equipped with a state-of-the-art vibration device, it ensures rapid unloading and automatic discharge of materials, streamlining your industrial filtration process.
Advantages: This filter press boasts remarkable high efficiency and substantial labor-saving capabilities, making it an ideal choice for modern industrial needs.
Disadvantages: While highly efficient, this filter press is optimal for operations requiring a smaller quantity of filtering plates, with a recommendation of not exceeding 30 plates to maintain peak performance.
