Stirred nutsche filters

Bachiller Nutsche Filter – Advanced Vacuum and Pressure Filtration System

Pressure filters from Bachiller (models FNB and FNB-S) are state-of-the-art solutions for solid-liquid separation in closed systems. Their design enables both pressure and vacuum filtration, making them ideal for applications in the pharmaceutical, chemical, cosmetics, and food industries. The sealed, hermetic vessel minimizes product loss and contamination risk, ensuring high product purity. For this reason, the Nutsche filters from the Spanish company Bachiller are a trusted solution in demanding processes where product integrity and safety are critical.

Filtration area: 0.07 m² to 15 m²
Volume: 19 – 15,000 L
Temperature: up to 200º C
Pressure: 3 – 10 bar
Material: Hastelloy®, stainless steel

Key Features

• Hermetic construction – the sealed vessel enables loss-free production without exposure to the environment, eliminating the risk of contamination.
• Bidirectional agitator – the specialized centrifugal agitator can be adjusted in both direction and height, ensuring suspension homogenization, effective mixing, and easy product discharge.
• Vacuum and pressure filtration – the system allows simultaneous vacuum and overpressure (up to 10 bar), significantly accelerating both filtration and drying.
• Temperature control – a jacketed vessel enables precise heating or cooling of the contents according to process requirements.
• Operational safety – robust construction complies with strict ATEX standards, allowing safe operation with flammable or explosive materials.

Options and Customization

• Available in stainless steel, Hastelloy, titanium, and other chemically resistant materials.
• Configurations range from laboratory scale (below 100 L) to full industrial installations.
• Various filtration media available: textile fabrics, metallic meshes, sintered or ceramic filter elements.
• The FNB-S version combines filtration and vacuum drying in a single unit.

Applications

• Pharmaceuticals: APIs, antibiotics, plant extracts, chemical syntheses.
• Chemicals: catalysts, pigments, polymers, minerals.
• Cosmetics: colorants, oils, active ingredients.
• Food processing: additives, flavors, vitamins, natural extracts.

Benefits

• High product purity ensured by a fully enclosed process.
• Reduced time and costs thanks to integrated operations (filtration, washing, drying).
• Increased safety and easy automation.
• Full compliance with GMP and ATEX standards.
