Experience the ultimate in operational efficiency with our state-of-the-art open filter press! Designed with an extended cylinder and robust beam structure, it utilizes a stainless steel chain (or slide) for seamless connection of each filter plate. This ensures simultaneous opening of all filter plates when retracting the pressing plate. Additionally, our integrated vibration device efficiently unloads and discharges materials automatically, making your processes faster and more convenient than ever before.
Advantages: Remarkable efficiency, significant labor savings, and enhanced operational productivity.
Disadvantages: Best suited for smaller operations, this model is recommended for use with no more than 30 filter plates.
