Nutsche filter dryer for pharmaceutical and chemical industries

Achieve precise filtration and efficient drying in one seamless operation with this advanced agitated Nutsche filter dryer, designed to optimize product purity and consistency in critical processing environments.

Performs Filtration, Drying, and Separation Operations

The MAVAZWAG® Agitated Nutsche Filters and Filter Dryers from GMM Pfaudler are versatile units designed for efficient batch operations in the pharmaceutical and chemical sectors. These systems excel in deep bed solid-liquid separation, using a specialized filter media to achieve comprehensive drying and discharge. Ideal for applications like antibiotics, APIs, and vaccine intermediates, MAVAZWAG® units integrate seamlessly into production lines with automation systems and CIP/SIP capabilities. Compact and adaptable, they are available in stainless steel, Hastelloy, and glass-lined options to ensure compatibility with corrosive environments. These units comply with GMP standards and offer advanced vacuum and solvent recovery systems, thus enhancing operational efficiency and safety. The unique “Clean Sweep” design facilitates total product discharge, while options for pilot unit testing ensure precise process optimization.
