Experience seamless operation with our open filter press, designed with an innovative extended cylinder and beam. Utilizing a stainless steel chain (or slide system), it ensures all filter plates open synchronously as the pressing plate retracts. Enhanced with a vibration device, it facilitates rapid unloading and automatic material discharge, streamlining your processes like never before.
Advantages: Unleash unparalleled efficiency and significantly reduce labor costs with our advanced technology.
Disadvantages: Ideally suited for operations requiring a smaller setup, we recommend models with no more than 30 filter plates for optimal performance.
