Immerse yourself in the seamless efficiency of our open filter press, a marvel of modern engineering. Crafted with an innovative extended cylinder and beam, this system perfectly synchronizes the opening of all filter plates using a robust stainless steel chain or slide system. When the pressing plate retracts, witness a symphony of precision as each filter plate opens in harmony. The addition of a state-of-the-art vibration device accelerates unloading and enables automatic material discharge, revolutionizing your workflow with effortless ease.
Advantages: Experience an unprecedented leap in operational efficiency with our cutting-edge technology, which not only boosts productivity but also slashes labor costs, setting a new standard in industrial processing.
Disadvantages: Tailored for operations where space efficiency is paramount, we advise selecting models with no more than 30 filter plates to ensure peak performance.
