Chemical filter dryer for fine chemical production
When processing chemical intermediates, precise filtration and drying are crucial to ensure product integrity and achieve optimal moisture levels for further manufacturing steps.

Filters, Dries, and Separates Solid and Slurry Products
The Pressofiltro® Series PF 2000 – PF 16000 from COMBER is a versatile filter dryer designed for pharmaceutical, chemical, and food product manufacturers. This equipment combines filtration and drying processes within a closed unit, optimizing production efficiency and reducing contamination risks. Its unique agitator blade design ensures effective and even product movement during the drying process, while the narrow agitator-to-wall clearances enhance emptying characteristics. Suitable for both batch and continuous operations, it handles solid, powder, slurry, and cake products, making it ideal for producing APIs, chemical intermediates, or powdered metals. With a control cabinet featuring PLC and HMI, it supports seamless integration with existing production lines. Constructed from materials like stainless steel and Hastelloy, it offers excellent corrosion resistance for handling aggressive substances. Certified for operation under the EU-Type Examination Certificate and capable of UL-approved installations, it meets high safety standards. The inclusion of a CIP system ensures thorough, contamination-free cleaning, making maintenance efficient while minimizing downtime.
