1Excellent corrosion resistance: Stainless steel, anti-corrosion alloy or anti-corrosion coating is adopted for the parts requiring contact with materials.

2Easy Maintenance:Complete overall turnover cover design allows flip angle of over 90°; overall structure of basket is exposed for easier cleaning of the machine and replacement of the filter cloth.

3All-directional online cleaning and disinfection: CIP online cleaning system is configured to complete all-directional cleaning and disinfection of the inner cavities, meeting the GMP standards and the requirements for cleanliness.

4Advanced structural design: Enclosed modular structure is adopted to avoid contamination caused by belt-worn dust and foreign matters.

5 Precise polishing is adopted for the parts requiring contact with the materials and no sanitary dead angle exists inside the equipment, meeting the GMP standards.

6Equipment has low gravity center, small floor covering area and is easy to maintain.

7 Variable-frequency startup and stepless speed regulation are designed to ensure stable operation and low failure rate.

8Internal nitrogen filling structure and nitrogen protection system are configured to meet the requirements for explosion protection in occasions involving toxic, flammable and explosive materials.

9Wide application scope: It can be used for the separation of not only suspensions containing solid particles but also fibrous materials. Manual discharging for better grain protection
