Agitated nutsche filter for solid-liquid separation
Ensure high-purity solid-liquid separation with minimized contamination risks and efficient handling of hazardous materials, catering to complex processing needs in batch operations.

Performs Filtration and Separation of Solid-Liquid Mixtures
The Agitated Nutsche Filter (FNB) from Bachiller is designed for efficient solid-liquid separation in industries such as pharmaceuticals and fine chemicals. This equipment operates by pressurized filtration, ensuring hermetic production to prevent contamination and preserve product purity. Suitable for applications including API production and pigment processing, it supports capacities ranging from 19L to 15,000L, with filtering surfaces between 0.07m² and 15m². Operating at pressures up to 3 bar(g) and temperatures reaching 200°C, it integrates seamlessly with batch operations, offering full or semi-automatic processes. The Agitated Nutsche Filter features a versatile filter media selection—textile, synthetics, metal—to ensure compatibility with diverse chemical environments. Built to comply with GMP and EHEDG standards, it is suitable for sterile applications and cleanroom installations. Maintenance is simplified with easy filter cloth exchange and a CIP/SIP system testable with the Riboflavin test. The unit supports further customization with options for mirror polishing, tight thermal insulation, and ATEX certified configurations, meeting rigorous production and safety demands.
