Our state-of-the-art once open filter press is ingeniously equipped with an extended cylinder and beam, utilizing a durable stainless steel chain (or slide) to seamlessly connect each filter plate. This innovative design ensures that all filter plates open simultaneously as the pressing plate withdraws. The incorporation of a vibration device enhances efficiency by enabling quick unloading and automatic material discharge, streamlining your operations like never before.
Advantages: Experience unparalleled productivity with our filter press known for its exceptional high efficiency and labor-saving capabilities, making it an indispensable asset to any operation.
Disadvantages: While ideal for operations requiring a limited number of filter plates, we recommend using no more than 30 plates for optimal performance and efficiency.
