Our state-of-the-art open filter press is enhanced with an extended cylinder and beam, ingeniously utilizing a stainless steel chain (or slide) to seamlessly connect each filter plate. This innovative system ensures simultaneous opening of all filter plates while the pressing plate retracts. Equipped with a vibration device, it facilitates rapid unloading and automatic discharge of materials, significantly boosting efficiency.
Advantages: Experience exceptional high efficiency and labor-saving capabilities with our advanced design.
Disadvantages: Ideal for smaller-scale operations, our system is optimized for use with up to 30 filtering plates.
