Immerse yourself in the effortless functionality of our revolutionary open filter press. Crafted with precision, this device boasts an ingenious extended cylinder and beam design. Equipped with a resilient stainless steel chain (or slide system), it guarantees the synchronous opening of all filter plates as the pressing plate retracts, resulting in unparalleled efficiency. Enhanced by an innovative vibration device, it accelerates unloading and enables automatic material discharge, thus elevating your operational efficiency to new heights.
Advantages: Harness the power of advanced technology to unlock unmatched efficiency, substantially cutting down labor costs and amplifying productivity like never before.
Disadvantages: Perfectly crafted for operations with limited space, we advise selecting models with a maximum of 30 filter plates to maintain peak performance and optimized operation.
