Experience unparalleled efficiency with our once-open filter press, which features an extended cylinder and beam. Each filter plate is seamlessly connected using a stainless steel chain or slide mechanism, allowing for simultaneous opening of all plates while retracting the pressing plate. Enhanced with an integrated vibration device, this innovation ensures rapid unloading and automatic discharge of materials, streamlining your industrial filtration process like never before.
Key Advantages: Our filter press boasts unmatched high efficiency and significant labor-saving capabilities, making it an indispensable asset for industrial applications.
Considerations: Ideal for operations requiring a smaller number of filter plates, we recommend usage not exceeding 30 pieces to maintain optimal performance.
