Experience the unparalleled efficiency of our Once Open Filter Press, enhanced with a premium extended cylinder and beam. Every filter plate is harmoniously connected with a robust Stainless Steel chain (or slide), ensuring synchronized opening of all plates upon pressing plate retraction. For swift material unloading, our state-of-the-art vibration device automates the discharge process for seamless operation.
Advantages: Delivering outstanding efficiency while drastically reducing labor requirements, our product stands out as a top choice for modern operations.
Disadvantages: While highly effective, this model is ideally suited for setups with a smaller number of filtering plates-best recommended for configurations not exceeding 30 plates.
