Delight in the flawless performance of our open filter press, masterfully crafted with an ingenious extended cylinder and beam. This cutting-edge equipment, featuring a sophisticated stainless steel chain (or slide system), guarantees simultaneous opening of all filter plates as the pressing plate retracts. Further enhanced with a state-of-the-art vibration device, it accelerates the unloading process and enables automatic material discharge, revolutionizing your operations effortlessly.
Advantages: Harness extraordinary efficiency and make substantial savings on labor costs with our breakthrough technology, setting a new standard in operational excellence.
Disadvantages: Perfectly designed for environments that require a more compact setup, we suggest models with 30 or fewer filter plates to achieve peak performance.
