Filtres Philippe® Horizontal vacuum belt filter

Horizontal Vacuum Belt Filter Systems

horizontal vacuum belt filters

Filtres Philippe® horizontal vacuum belt filters provide an ideal solution for solid-liquid separation.

Technology and expertise ensure 98% uptime – and enable us to meet process requirements. Filtres Philippe®  is dedicated for mineral or bulk chemical processing application.

The belt is a key component, as well as a significant portion of system cost. Our filter cloth and rubber belt system are optimized because we manufacture and test our own belts. We have dedicated facilities at our plant, in Le-Mêle-Sur-Sarthe. Then, we run the belt on a proprietary robotic machine to remove residual stresses, true edges, cut grooves, and bore drain holes. Our belts are factory spliced and hot vulcanized, and feature chemically bonded belt curbs (patented) to ensure a long life. The modular construction of our belt filter ensures the highest operating efficiency, and easy access for routine maintenance – as well as a perfect alignment. Frames are constructed from the highest quality steels and are assembled by bolting together for simpler disassembly. The belt can be replaced from the top, speeding change-out in facilities with limited access. The exclusive tilting vacuum box design enables quick inspections as well as easy access to replaceable wear strips.

In the last years, HASLER Group has also developped new solutions to reduce water consumption (up to 100% recycling) wich can be implemented for your projects.

Finaly, the main advantages of our horizontal vacuum belt filter are

  • Operating factor up to 99%
  • Washing Efficiency
  • Large filtration range (0,25m² à 200m²)
  • Availabilty à Up to 98%
  • Easy maintenance and utilization
