Designed with an extended cylinder and robust beam, this innovative equipment utilizes a sleek S.S. chain (or slide) connection for each filter plate, ensuring simultaneous opening as the pressing plate withdraws. Equipped with a cutting-edge vibration device, it guarantees rapid unloading and automatic material discharge, elevating your filtration process to unmatched levels of convenience.
Advantages: Embrace unmatched high efficiency and significant labor-saving benefits, propelling your operations to new heights of productivity and ease.
Disadvantages: Best suited for operations with a limited number of filtering plates, ideally no more than 30 pieces of the recommended plate type, ensuring optimal performance.
