Vacuum belt filters for solid-liquid separation
Ensure high-efficiency solid-liquid separation and maximize filtrate recovery with continuous vacuum belt filtration. Ideal for processes requiring precise cake drying and washing, this system offers industry-leading performance and adaptability for various applications.

Separates and Dries Solid-Liquid Mixtures Continuously
The PHILIPPE Vacuum Belt Filter from HASLER Group is engineered for efficient solid-liquid separation across various industries, including fertilizer production, hydrometallurgy, and chemical processing. This continuous filtration system leverages a vacuum-driven process to ensure high-efficiency cake drying and filtrate recovery, catering to applications ranging from ammonium nitrate fertilizers to refined bauxite.
Using an endless belt system with patented edges, it facilitates superior containment and thorough separation under gravity and vacuum forces. The system supports diverse process requirements through customizable washing zones and is designed to achieve over 98% filtrate recovery, depending on the material.
Operational throughput varies with configurations up to 200 m² and is enhanced by integrated PLC controls allowing precise adjustments and remote monitoring. The equipment is optimized for energy efficiency with optional recirculation systems that minimize water usage. Constructed from stainless steel and other durable materials, it offers resilience against corrosive and abrasive substances.
The PHILIPPE filter meets CE standards, emphasizing safety and compliance. Its design includes features like an easy-access pneumatic vacuum box, automatic cloth guidance, and tensioning systems, reducing downtime and ensuring seamless integration into existing production lines. For maintenance, the system is equipped with a tilting vacuum box for straightforward access and cleaning, supporting high-pressure and ultrasonic washing. HASLER Group offers extensive customization and engineering support to tailor the filter to specific processes and product requirements.
