Experience the epitome of seamless operation with our state-of-the-art open filter press. Ingeniously crafted with an extended cylinder and beam, this system features an advanced stainless steel chain (or slide system) that ensures simultaneous opening of all filter plates as the pressing plate retracts. This marvel of engineering is further enhanced by a vibration device, facilitating rapid unloading and automatic material discharge, streamlining and optimizing your operational processes like never before.
Advantages: Unleash the power of unparalleled efficiency and drastically reduce labor costs with our groundbreaking advanced technology, setting a new standard for excellence.
Disadvantages: Perfectly tailored for operations requiring a compact setup, we recommend models equipped with no more than 30 filter plates to ensure optimal performance and functionality.
