1. Plate structure can assure stable running and easy operation. Liquid damping technics makes the vibration isolation and damping performance of the machine more perfect. 2. Long bearing support length, good supporting performance. Bearing support is individual structure type and easy to carry through maintenance. 3. Equipped with pneumatic auxiliary scrapper and recoil device, residual filtrated layer can be effectively cleaned, so the filtration effect will be improved. 4. Nitrogen anti-explosion device and online cleaning technics have been applied in the machine.
