Combine vacuum pressure as impetus, the filtration cloth as the filtration medium. accomplish the solid-liquid seperation.

1.  The process of the feeding, filtering, washing, discharging and the regenerating can be achieved efficiently and automatically.

2.  It can wash slurry by the methods of multistage current or countercurrent. The filtration liquor and the washing liquor can be collected separately.

3.  It can filter a thin layer cake quickly for the hard filtration and the high viscosity slurry.

4.  It is flexible to assemble equipment because of the modular structure.

5.  It is convenient to do the remote and spot control for the PLC.
